Re^3: Audio::WAV data problem

i think i might be able to use the code you provided if i remove the header from the WAV file and apply it to the rest of the file. however, i am afraid it might produce the same strange results if the problem is that Audacity is putting something strange in the file. i will certainly give it a try when i have some time.

i made my own files instead of making them in Audacity. i think the problem is that Audacity does strange stuff. it is really an editor for audio files and there does not seem to be much concern with the accuracy of single samples. i sort of remember running into this sort of problem in the past. for example, it does not like DC offsets and tries to fix things up at the end of a file. it seems that when it makes "silence" there is some jitter about 0. there are possibly some other quirks. i tried the code you provided and it works just the same as mine although it is a little more elegant. thanks for helping me to see that there is really nothing wrong on the Perl side of things.
