Pulse Code Modulation. PCM. Microsoft "WAV" format can have compression and damage incorporated in it, but by convention almost never does. It's one of the formats you can do production and editing in without damage cause by the file format. the other one is Apple AIFF. Those two are easily converted into each other with no damage.

Of course, there's no compression, so the files are very large.

All the compressed formats, MP3, AAC, etc get worse and cause damage with use. These are intended as delivery formats, not production formats.

Hi koz,

Thank you very much for the quick reply! My situation is, I use both audacity and ffmpeg to convert mp3 files to wav, both using PCM encoding with same sample rate, # of channels and so on, so the header information for these 2 files are exactly the same. However the software I am using can recognize the wav file generated by audacity but not the one by ffmpeg. Do you know what is the differences between the wav files generated by these 2 different tools?
