4+ channels of Bluetooth/wifi audio using jambox/logitech speakers?

May 14, 2013 | 3:06 pm

Are there any (relatively) inexpensive ($3-500) solutions for achieving surround sound (at least semi-quadraphonic, i.e. two stereo speakers) using commercial bluetooth/wifi/rf speakers? Ideally I would like to do the audio routing through Max, Logic, Live or M4L. I have an 8-output interface where I could run 1/4" out to speakers that require their own receivers with wireless capabilities, but I’d rather keep this set up as light as possible, because it would mainly be for field use and outside class demonstrations. If it’s possible to send two separate stereo feeds (maybe using soundflower?) to different bluetooth devices, then my next question would be, would it be possible to send 4 mono feeds to 4 different stereo speakers? Then I could really have some fun…

So I guess the main question here is "is it possible to create an aggregate output device for Bluetooth devices?" Similar to what you can do with audio interfaces, but with Bluetooth in a way that will let you designate in the sound preferences which channels go to which device?

No one here is interested in wireless audio routing? Put down your ipads and iphones for a second, and contemplate the possibilities of setting up mobile/wireless surround sound installations anywhere in the world, just carrying a laptop and 4 small battery powered speakers…

Then, once we’ve figured out how to make this possible, pick up your i-devices again and design a killer quadraphonic panning interface like the one that was included in the Dexter app by jazzmutant over 5 years ago! 100% wireless and 100% fun in the sun… can’t think of anything cooler to do with Max, besides finding a killer multitouch monitor for my new hackintosh to run live painting software and custom visuals for half the price of an ipad (see my most recent forum post)…

Come on bluetooth wizzes, it’s your time to shine!

Myeah wireless audio… got some experience with that lately. Tried cooking up DIY wearable senders with this kinda Chinese boards: http://www.freqchina.com/en/productview.asp?id=49 . Fail. Too unreliable signal, which could totally be due to my lack of electronics skills though.

I reverted to these discontinued devices: http://www.creative.com/emu/products/product.aspx?pid=18609
Stereo and 3 radio channels to choose from so could provide up to 6 audio channels. I’ve been using 2 devices alongside each other, strapped to my arms.
There’s lotsa noise in the signal but I haven’t yet confirmed whether it’s the devices or my audio source electronics (photodiode+preamp) generating it.

As for your original question, I don’t know about aggregating bluetooth audio devices. If they show up as a regular audio interface in the OS, my gut feeling is it would work.

Question is whether you’ll get decent sound quality from them.

Just checked, the noise is not from the e-mu devices but my pre-amp circuit.

no idea about bluetooth specific issues but as DTR, my guts tell me that with Jack anything routing related should be possible.

Not sure if you’ve ever heard one of the larger jamboxes (jawbones I think they’re called), but they pump sound and they have a pretty impressive battery life. I’m not sure how much better the audio quality would be from one of those E-MU devices, but maybe I’ll look into it. Still really interested in routing bluetooth audio, it appears they show up in the audio output devices list in system preferences so I imagine they should work for creating an aggregate device? Anyone with previous experience in these regards that could confirm/deny this?

Multi-output bluetooth audio from a single mac, feasible or not? It’s hard for me to believe that no one else on these forums (or anywhere else on the internet for that matter) has developed a similar itch for mobile, wireless surround sound!?!?

hi gmix, I have the same kind of question. I want to use two battery powered portable pa speakers via bluetooth – to avoid cables!!!!

I have set my eyes on the "Samson expedition express". How do I connect the 2 channel’s outputs from MAXMSP with the two different bluetooth devices? This is your question as well, right?

I was thinking that if you could try to turn on for example two or more smartphone’s bluetooth, and then check out if you can have max / your computer find them and connect with both (all). Doesn’t matter that you don’t use them for routing sound. If this is possible, routing sounds should not be a problem, right?
