looking for open source (free) software codec for an uncompressed audio over ip stl. i want to home brew a wireless uncompressed ip stl using surplus wisp equipment or off the shelf consumer wifi equipment.
any idea's?
I don't know about sending uncompressed audio, but you could use a lossless audio codec like FLAC which is open source. A quick google shows someone using FLAC in this manor:

Good luck.
I did some snooping around awhile back about this, but I found that both hardware and software are expensive. I never ran across any such items as surplus, because the technology is still in its infancy. Here's one:

... but even that is for ethernet, not designed for wireless AFAICS. My guess is that wireless gear, especially off-the-shelf, isn't adequate to handle uncompressed audio. Here's some more stuff (watch linewraps):
How far does the wireless signal have to go? If a short range, you might consider buying the new Sennheiser digital wireless headset and tinkering with it .... after all the audio only has to go one way meaning bi-directional signals aren't necessary, so you don't really need IP gear, per sé.
But who knows? Maybe your research will turn up a bright gold nugget 😉
How about the Barix Ex-Streamer?
Their are at least two distinct devices. A streaming device and a receiving device.
I am not familiar with the audio formats employed by Barix.
i am on disability (thus not much money) and am looking for something i can make using what i have on hand.
The Barix gear is MP3, i.e., compressed.
Once again, uncompressed audio over wireless IP is in its infancy, and is usually part of wireless HD video systems because there is more money in video.
I'm not saying it can't be done in someone's garage shop (Steve Wozniak and Steve Jobs started Apple Computer that way), but if you come up with something that works for cheap ... well ... you'd better patent it.
I've used USB microphones. And, there are several audio to USB convertors available that convert line level audio to USB, i.e. USB sound cards.
From there, a WIRELESS USB device could transport the audio to a PC. Range might be a problem but that should be an uncompressed audio data stream arriving at the PC.
Someone out there has probably figured out how to extend the range of the wireless USB devices with pie pans and coat hangers.
Not sure why it must be over IP, but how much wireless range do you need? If short, would this kit work for you? ...

... not too expensive. Range isn't given, though.
