Thanks.Â* On the subject of compression, the bulk of the files I'm
working with are m4a recordings of a male speaking voice and they have a

them (and there are a lot) manually adjusting the levels, but could
applying compression achieve a decent quality result?Â* I do need to
retainÂ* the clarity and unmuddyness they have at present.Â* I've very
little experience with compression of audio files and would be grateful
for any thoughts.

yes. that should work if you have a decent package.
Audacity is not bad for that


Thanks.
