pbrinich asks: "I am in the process of designing a new audio system for a house under construction. I have been looking for a purely IP-based audio system. Has anyone heard of a good, open, IP-based, multi-zone audio system that is ready for consumer use? I have read a bit on a company called netstreams and their DigiLinx line. Any thoughts?"

How I'd do it (1)

Marxist Hacker 42 (638312) | about 9 years ago | (#13768751)

RealNetworks StreamServer. Then you could simply write a webpage on a central server for doing such things as choosing from a centralized MP3 library, or setting another audio source through server side scripting and an IR blaster. At that point, any computer in the house with a web browser becomes an interface point for your sound server- and the local computer soundcard and speakers become the output.

A very interesting idea- and maybe evenutally when I have a 400GB hard drive on my home server, I'll do something similar.

Enjoy your iTunes music library in virtually any room of your house. Share a single broadband Internet connection and USB printer without inconvenient and obtrusive cables. Create an instant wireless network on the go. Extend the range of your current wireless network. How many devices do you need to do all this? Just one.

Presenting AirPort Express.
Speed 54 Mbps

Featuring AirTunes for playing your iTunes music wirelessly on your home stereo or powered speakers, AirPort Express brings not only the Internet but your music to wherever in your home you like to enjoy them most -- whether you use a Mac or Windows PC. Unmatched in its ease of use, it delivers data rates up to 54 megabits per second, fits in the palm of your hand so you can take it wherever you go -- and it costs just $129.
Driving the Wi-Fi Revolution

In 1999, Apple sparked the wireless revolution with the introduction of AirPort, the first affordable and easy-to-use solution for accessing the Internet without restrictive cables. In 2003, AirPort Extreme took your unwired connection to the next level by harnessing the superfast 802.11g wireless standard for data rates nearly five times those of the 802.11b standard that the original AirPort used and many current wireless networking devices still use. With AirPort Express, Apple continues to advance wireless, delivering the first device to pack wireless networking, audio, printing and bridging capabilities into a single affordable, portable unit.
AirTunes Unleashes Your Music
AirTunes

AirPort Express with AirTunes brings your iTunes music in your Mac or PC into your living room -- or wherever in your home you have a stereo or a set of powered speakers.(1) All you have to do is connect your sound system to the audio port on the AirPort Express Base Station using an audio cable (included in the optional AirPort Express Stereo Connection Kit) and AirTunes lets you play your iTunes music through your stereo or powered speakers -- wirelessly. iTunes automatically detects the connection of your remote speakers, so you just have to select them in the popup list that appears at the bottom of the iTunes window and click play.(2)

Enjoy your playlists, set iTunes to shuffle through your entire library or repeat your favorite songs over and over again -- however you like to enjoy your music on iTunes, you can now enjoy it that way through your stereo speakers, wherever they're located in your house.

Buy more than one AirPort Express Base Station and connect one to every stereo or set of powered speakers in your house -- one to your stereo in your living room and another to a pair of powered speakers in your kitchen, for example. Its small size and affordability make it perfect for having more than one. Imagine being able to play your iTunes music on whichever speakers in your house you prefer.
AirTunes

Because AirPort Express is so compact, you can also easily take it along with your laptop to a friend's house and share your unique musical taste on your friend's stereo.
Add Music to Your Current Wireless Network

If you already have a wireless network in place, you can use AirPort Express to add music to its capabilities. Let's say, for example, you have AirPort Extreme set up in your den. There's no need to scrap this setup and create a whole new one with an AirPort Express Base Station, your DSL or cable modem, printer and stereo all in one place. Simply connect AirPort Express to your stereo in your favorite music room and plug it into an electrical outlet -- it wirelessly links to your existing network, letting you play your music in your room of choice without moving anything or connecting anything else.
Connect Wirelessly

AirPort Express uses the 802.11g wireless standard to deliver blazing data rates -- up to 54 Mbps.(3) It supports both Macs equipped with an AirPort Extreme Card and Wi-Fi-compliant 802.11g Windows PCs, as well as Macs with the older AirPort Card and 802.11b Windows PCs. Everyone in your family can surf the web wire-free because AirPort Express provides simultaneous wireless Internet access via your DSL or cable modem for up to 10 computers(4).

AirPort Express connects you and everyone in your family not only to the Internet but to each other. Since it employs the powerful 802.11g standard, you can wirelessly share photos, movies and other files without having to worry about slow data transmissions. Nor do you have to concern yourself over a difficult network setup procedure. AirPort Express uses the revolutionary Bonjour technology in Mac OS X to allow your AirPort-equipped Macs running Mac OS X to detect each other with no effort on your part -- they discover each other just by virtue of being within the range of the network.
Extend Your Network
Extend Your Network

If you already have a wireless network in your home and would like to extend its range, AirPort Express is your answer. Suppose you want to connect to the Internet with your PowerBook in an area that lies beyond the 150-foot range of your AirPort Express or AirPort Extreme Base Station. You can use AirPort Express as a wireless bridge to extend the range of your primary base station.(5)

There's no need for extra wires or cables -- serving as a bridge, AirPort Express doesn't have to be physically connected to your primary base station or to your DSL or cable modem. Simply place AirPort Express within the range of your primary base station and near the area where you'd like to enjoy your wireless connection.

      1. Requires compatible stereo system or powered speakers.
      2. AirTunes requires iTunes 4.6 or later.
      3. AirPort Express uses the 802.11g wireless standard. Accessing the wireless network requires an AirPort or AirPort Extreme enabled computer or Wi-Fi-certified 802.11b or 802.11g computer. Achieving data rates of 54 Mbps requires that all users have an AirPort Extreme or Wi-Fi-certified 802.11g enabled computer and connect to an AirPort Express Base Station. If a user of a Wi-Fi-certified 802.11b product joins the network, that user will get up to 11 Mbps and AirPort Extreme and Wi-Fi-certified 802.11g users will get less than 54 Mbps. Actual speed will vary based on range, connection rate, site conditions, size of network, and other factors.
      4. Wireless Internet access requires a wireless-enabled computer, a base station or other access point and Internet access (fees may apply). Some ISPs are not currently compatible with AirPort Express.
      5. AirPort Express can extend the range only of an AirPort Extreme or AirPort Express wireless network.
      6. Wireless printing over USB requires Mac OS X v10.2.7 or later or Windows XP or Windows 2000 and a compatible printer.
      7. Cables for connecting the AirPort Express Base Station to a DSL or cable modem, USB printer or a stereo or a set of powered speakers are sold separately.

Ever wonder why the dialog doesn't sync with the actors' lips when you watch a DVD on your computer? Even if you have [dedicated] hardware-accelerated MP3?

And that's just local to one system. Try pushing an audio stream across two different TCP/IP stacks - heck, "ping" [which lives in ICMP, somewhere down beneath even UDP] is lucky if it can make 1ms or 2ms over CAT5.

Oh, and yes: YOUR EARS ARE VERY, VERY SENSITIVE - THEY CAN AND WILL HEAR THIS STUFF.

I've always streamed the video with the audio over the link to stop that problem. But on local video hdtv compressed mpeg4, and my PC seems to play it without a sync problem.

I dont think the latency in your home lan would be enough, though, what is the noticable latency, 5ms? 20ms?

Ever wonder why the dialog doesn't sync with the actors' lips when you watch a DVD on your computer? Even if you have [dedicated] hardware-accelerated MP3?

Maybe because DVD audio isn't MP3?

You need hardware-accelerated MPEG-2 decoding in video, a processor fast enough to demultiplex and decode your preferred audio stream AND the video, and buses fast enough to shove all that data through, alongside the usual OS noise. I don't recall ever seeing a sound card that offers hardware AC3 decoding. Your biggest latency issue is going to be the sound buffer: if you can't fill it fast enough, the system has to use a bigger one, and it will desync.

I'd check your system before you start blaming that. I've owned a Pentium III 900 MHz, an AMD Athlon XP 1700+, and a Pentium 4 3.0GHz system, and neither had any trouble at all with synchronization. Maybe it's your software, also. On a Windows box, WinDVD, PowerDVD, Windows Media Player, and PCFriendly all seemed to work fine for me on both systems.

Just 3 hours ago I was talking to someone who was trying this out. He said that when he has watching a DVD on his computer downstairs, by going upstairs the system should make the movie go upstairs too.

It does security, telecom, home automation, media, entertainment and computing. Seems to run on Linux too, and uses your modern mobile phone as a remote control / tracker.

Squeezebox2 (2, Informative)

Malor (3658) | about 9 years ago | (#13769472)

Slim Devices' Squeezebox2 is very, very good. It's about the size of a VHS tape, has a truly beautiful, professional-grade display, and talks to a central server. It outputs both digital and analog, either passing data via coax and optical, or using the high-quality onboard DACs.

On my fairly forgiving (rather warm/laid back) main speaker system, I wasn't able to hear any difference at all when switching back and forth between the DACs on the Onkyo 901 and the SB2. I don't have golden ears or anything, but they're reasonably good, and digital and analog mode sounded identical to me. The 901 retailed at $1500 (though you could buy them at around $950), so the SB2 matching that means it's doing a pretty good job. If you happen to have gear that's better than mine, and you think you can hear a difference.... well, that's what the coax and optical outs are for.

The unit also has a headphone jack, which sounds good. It does not, however, seem to have a huge amount of onboard power, so you'd probably want a separate headphone amp for high-impedance cans like the Sennheiser HD580s or 600s. (They still sound good without one, but have much more authority with more power driving them.)

The higher-end models come with built-in 802.11g wireless, which is more than fast enough to support several streams (ie, several players), though if you got seriously into the networked music thing, with lots of stations, you'd probably want to do it with wires. The wireless model will also bridge to Ethernet via the single RJ45 jack. If you add a hub, you can bridge a whole stack of stuff to your WiFi.

You can control the boxes from either the included remote, using a very easy interface, or via web browser. If you have several SB2s, you can coordinate them all to play at the same time, so that you have synced music in several rooms or the whole house. (I believe it will do subgroups as well, but I have only the one and can't test that.) I'm not sure if units will sync from the remote or only from the web interface. I'm fairly sure you have to CREATE the sync via web browser, but I suspect it will probably just work from then on. I believe you'd hit play on any unit in a group, and they would all start playing.

Of course, if that DOESN'T work, you can add the feature yourself. The server software is Perl and very open-source. I believe the boxes themselves run Linux and can be hacked on, but honestly, the software is just so good that I can't really imagine wanting to. Maybe if I had a second one... that display really is neat, and it'd be fun to play with it for other stuff. I'd just hate to break my only one.

The box natively speaks MP3, FLAC, and WAV. The server software can translate from many other music formats, and will sync with iTunes if you have that. (I don't think it can play Apple's DRM, so you'd have to crack that first.) It understands CUE/BIN images, which is GREAT, because that's how I have all my music archived. It actually supports CUE/FLAC too, so I compressed all my music to save some space. I have verified that I get bit-perfect output... playing a DTS-encoded WAV file through the SB2 (at full volume, of course) gives me music on a DTS-enabled receiver, not just noise. If the bitstream is damaged in any way, DTS doesn't work. It just comes out as a hiss. So a DTS file is a great test of bit-perfect transfer... if you hear music, you're delivering a truly lossless stream.

If you archive your CDs losslessly, then you'll probably get better results from this unit than you'd get from most 'real' CD players. You can't scratch a CUE file, or get it dusty. I have no way to test it, but I'd guess that eliminating the vagaries of the optical pickup would probably diminish jitter a great deal. I've never learned how to hear digital clock jitter myself, but some people are very focused on the issue. I don't know if it REALLY matters, but if it does, my guess is that the SB2 should do a better job than most real CD transports would.

Overall, it has more features than you can shake a stick at... the software has been worked over very thoroughly by a bunch of real music geeks. There is just a TON of stuff buried under the easy interface... if all you want is music, that's just a few buttons away, but there's alarms, and snooze functions, and internet streaming... lots and lots of power under the nice interface.

If you haven't gathered this already, I'm very happy with mine. This is a dynamite product.

Re:Squeezebox2 (1)

uradu (10768) | about 9 years ago | (#13771064)

Or, for about half that, you can get a Roku SoundBridge [rokulabs.com] , and you also end up with a much more attractive device. It also works in Squeezebox mode if you must, though doesn't offer all its features in that mode.

Re:Squeezebox2 (2, Insightful)

Malor (3658) | about 9 years ago | (#13771301)

Not for comparable features/quality, you don't. The M2000 has a better display than the SB2's, (512x32 versus 320x32), but is a great deal more expensive, at $400. The wireless SB2 is $250 right now. There are codes floating around at times that will give you another $20 off that. Roku's M1000 is about $200, but its display is inferior(280x16). And note that BOTH the 'high-end' Roku models only support wireless-B mode. If you have a G network, setting it to mixed mode will give you a speed hit right up front. And you're not going to be able to run more than a couple of boxes if you're using lossless audio. (unless, of course, you want to spend a whole lot of money buying more APs.) The SB2, with native G support, would drive roughly five times as many players, which certainly improves your chances of having useful bandwidth left over once your installation is done.

Slimdevices also offers a wired-only version of their player at $179, which is exactly the same as the higher-end model in all respects, less the antenna and wireless circuitry. Roku's cheapest model is $149, but its display is 2 lines of 40-character monochrome. Yuck.

I also note that Roku doesn't mention what DACs they're using. The SB2 uses Burr-Browns, which have a sterling reputation. You may not need them if you're outputting digital to a (good) receiver or prepro, but if you have cheaper gear or want to use headphones, the SB2 is probably better. And keeping your options open never hurts.

I'll give the Soundbridge an edge on appearance, but the hardware appears to be both overpriced and under-specced. The SqueezeBox2 blends very nicely, has a very attractive display(quite a bit better than the M1000's, not as nice as the M2000's), and does native G and painless network bridging. And it has really good DACs. It's a no-compromises product.

I don't, after all, buy audio gear to look cute. The SB2 looks like a quality piece of hardware (which it is), and that's all I need. I'll leave the chrome edging to the Bose crowd.

It's also nice to support the people sponsoring the SlimServer software, which can (as you point out) be used with other hardware than their own. Money invested there benefits everyone.

Re:Squeezebox2 (1)

uradu (10768) | about 9 years ago | (#13772920)

The SB2 may have higher quality components, I really haven't checked into that. The higher resolution display doesn't excite me much, I just need a what's-playing status, and the SoundBridge does just fine. Other than the resolution difference, it's the same type of VFD display, and they both look great. What seriously turns me off the SB2 is the looks--there's no way around the fact that it looks like a cheap clock radio. Of course, looks are in the eye of the beholder, so YMMV.

Regarding sound quality, I can't really argue. I'm playing MP3 tracks on Logitech X-230 speakers in the living room, so HiFi isn't the main consideration. To me and everyone who has heard it play it sounds just fine, so I'm not going to argue much beyond that. I was going for an easily concealable system that blends into the room without screaming "tech-freak" (which, alas, I am in most respects other than purist audio).

The wireless is indeed only B. However, it does use a CF card, so theoretically it could be upgraded to G, provided Roku added support for one of the cards. Since I have my entire house profusely wired with CAT5, with conduits running to most corners of most rooms, I have no need for wireless, so that aspect doesn't concern me. And considering that my M1000 only cost $150 (after rebate), it's still a better deal to me than the SB2. I think many BB stores still sell the M1000 packaged as an M500 for the M500 price.

I have always respected and liked the Slim guys for their garage workshop roots and open software. I just never cared for the implementation of the hardware and how much they sold it for (though I do understand why), neither in the old days when you just got a naked circuit board, nor in the SB2 "clock radio" incarnation.

One thing I like about the SoundBridge is that it implements an open standard, UPnPAV. While it is still emerging, my feeling is that it has a good chance of becoming big. There are UPnPAV servers that run on all sorts of hardware--the TwonkyVision server runs on many of the NAS boxes and even some routers. There are very flexible ways of controlling a UPnPAV setup, and a bunch of different clients, including software running on a PocketPC that allows streaming music to anywhere in your WiFi range cordlessly (i.e. no power wires).

Plus the SoundBridge also supports a variety of server types, including iTunes, Slim, MusicMatch and UPnPAV. While you could argue that it's better to support one system and do it well, the Roku hardware does work quite well in most setups.

Re:Squeezebox2 (1)

Malor (3658) | more than 8 years ago | (#13868769)

If you're still reading this thread, I thought I'd mention that they just announced (I got the mail about 10 minutes ago) the Squeezebox3, which adds native WMA support and looks nicer. But it's back to the old $299 price for the wireless version, $249 wired. (SB2 is $249/$199). Same very, very high-quality components.

The new design is more vertical and cleaner. It still kind of reminds me of a clock radio, but it's nicer-looking than the VHS-tape clock radio style of the SB2.

Re:Squeezebox2 (3, Informative)

FreeForm Response (218015) | about 9 years ago | (#13771369)

I'm also a huge fan of my Squeezebox, and I thought I'd share a couple of tips with you.

If you have several SB2s, you can coordinate them all to play at the same time, so that you have synced music in several rooms or the whole house. [...] I'm not sure if units will sync from the remote or only from the web interface. I'm fairly sure you have to CREATE the sync via web browser, but I suspect it will probably just work from then on. I believe you'd hit play on any unit in a group, and they would all start playing.

The synchronization can be done from any Squeezebox connected to a given SlimServer, with any other Squeezebox(es) also connected to that SlimServer. They do behave as you expect, in that the "play" signal from any member of the group propagates to all of the other members. The synchronized Squeezeboxes also share playlists, though, so you can organize a playlist (or load a saved one) on one Squeezebox that all of them will then follow.

Also, the SlimServer software ships with a Java-based Squeezebox emulator called SoftSqueeze. Your SlimServer web interface should have a link to it somewhere; in the Default skin, it's down in the lower-left corner of the left-hand frame. This software can be used to turn virtually any computer (since it's Java and all) into another Squeezebox, which will then connect to the SlimServer and appear exactly like a hardware Squeezebox. The SoftSqueeze clients can even be synchronized with hardware players.

Have fun!

itzdandy (183397) | about 9 years ago | (#13774743)

firstly, latency sucks but can simply be ignored. for instance, if all devices on a network have a reatime clock, they can sync this clock with a central machine and calculate scew from latency to be very very precise. now the player can be told to play this stream starting at this second. now every device will cache a small amount of data and play the file based on realtime instead of play-as-streamed. now if a song should be playing @ 12:35pm(@23.638 seconds) it will be on all devices and latency will not be an issue.

next, wired devices can of course be used as wireless devices with a cheap access point in client mode(think WRT54g). this way you can link your x-box/ps2/network media player on the same client mode router!

Re:zen (1)

LordMyren (15499) | about 9 years ago | (#13777989)

Afaik the real bitch is that the soundcards have different skews, system clocks are easily adjustable and de-skewed with working ntp. Getting the sound card not to drift from the computer--- more problematic. also, low latency interrupts are very problematic to generate to start play.

Please discuss though... I'm very interestd in getting synced audio.

Re:zen (1)

itzdandy (183397) | about 9 years ago | (#13778201)

i think that calculating system clock from a central machine and adjusting based on average latency will be 'good enough'.

interesting thought about soundcards skewing playback. possibly different clock values on sound chips could do this. 1 or 2 ms is 'ok' but humans have sensitive enough ears to pick up much more, especially on multichannel output.

i think 'smart' programming should be able to anticipate starts/stops on playback to be reasonably acurate, but the song could quite litterally drift out of sync...

anyone have a more technical idea of how these latencies and clock skews could effect output?

another thought:
i suppose you could have the playback program do a "play this packet at this time" as apposed to "start playing stream now" so if the playback were at a different pace on different machines it would be for single packets of audio data. i know this may add an unreasonable amount of overhead OR even cause audio quality to suffer if the playback progam/sound chip had a significantly different playrate than the source.

What I really like about it is that customers can do the following: 1). listen to multiple streams of music from a hdd based media server 2). view the feed from any Panasonic IP camera on any in-wall touchpanel, their PC, web tablet or PDA. 3). control the entire system from their PC (I have one installation that is set up for that). 4). and now control their lighting and heating/cooling system from the same interface. But the best thing I like is that all of the firmware is upgradable so I can add features to a customer's home. By the way, sound quality is excellent because I've placed those little amplifiers / room controllers at the speaker location, so I'm not sending analog audio over 100 feet of 16 AWG speaker cable. I'd recommend the system to anyone looking to install a high quality, completely IP based multi-room audio and control system.

It's a wee bit expensive, but in my opinion Sonos is the best complete system out there. Check it out - http://sonos.com/ [sonos.com]
