In telephony, a standard audio signal for a single phone call is encoded as 8,000 analog samples per second, of 8 bits each, giving a 64 kbit/s digital signal known as DS0. The default signal compression encoding on a DS0 is either ?-law (mu-law) PCM (North America and Japan) or A-law PCM (Europe and most of the rest of the world). These are logarithmic compression systems where a 12 or 13-bit linear PCM sample number is mapped into an 8-bit value. This system is described by international standard G.711.
I have sent raw audio from my Arduino to a Web Host and saved it as a file
I think we're on the right track with the WAV header. But then I can't use uLaw compression?
I'm sure I can figure out how to play a WAV file by referencing the file URL with a specific browser. How can I make it easy for everyone else regardless of their browser? Is there some sort of website where I can pass the WAV file URL and it will play thru the browser?
