There's an interesting aside here relating to midi and pianola. Both these techniques are extremely effective lossless compression technologies but solve the problem in a quite different way. User:Rjstott


I have moved the page Audio compression to Audio data compression because I believe it more accurately describes the topic of discussion and leaves the original page for a discussion of audio compression in recording.

Audio compression is now a disambig, as it should be. - Omegatron 23:02, Apr 6, 2005 (UTC)

Under the section titled "Lossless compression", it is said "...audio waveforms, which are generally difficult to simplify without a (necessarily lossy) conversion to frequency information...". I dispute that conversion to frequency-domain is necessarily lossy. 57.66.65.38 13:06, 15 January 2007 (UTC)Andrew Steer www.techmind.org


can someone tell me any simple algorithm to compress a wav file back to a wav file. i'm not sure if lzw will work. Xhamlliku

[edit] Latency

"In general, latency must be 15 ms or lower for transparent interactivity."

This is nonsense. Transaltanic telephones calls always have a latency significantly greater than this, thanks to the distances involved:

15,000,000 round trip / 300,000,000 metres per sec = 50 ms.

With modern telephone systems it is difficult to impossible to notice any latency. I have chopped out the above sentence.

[edit] lzw compression of wav file

I don't know where user Xhamlliku went but I know of no reason lzw compression wouldn't work with a .wav file.. Charlie 11:52, 26 October 2005 (UTC)
