These files are sometimes also used in acoustic experiments. Here we describes how to convert a 16-bit integer sound file to a .WAV file, and explains some of the technical details of the .WAV file construction. http://www.geocities.com/tpsbpl/wav_file.zip http://www.8051projects.net/forum-t2250.html 2009-01-08T09:57:23-08:00 Ajay Thank you TPS, its really informative..so.. if i record a wav file with 8Khz sample rate and 8-bit PCM, is it easy to play on 8051? the only problem is the size..that is the reason i used Roman Black's BTc algorithm.. but it gives a poor sound quality.. i can still try to optimize it rather..
