Well, in a different thread you mentioned that you were concerned about space, so I assumed that compressing your WAV files would be a good idea.
As far as quality is concerned, I’m pretty sure that you won’t be able to hear a difference when you use a good encoding software and appropriate compression parameters. Of course, you should
not just use default parameters – by default, most software uses 128 kbps CBR with ISO joint-stereo mode and algorithmic parameters that present a trade-off between quality and speed. Obviously that is not optimal.
Personally I use LAME (
audio/lame) with the options
-m j -q 0 -v -V 2 -B 320
. This uses VBR with joint-stereo (
-m j
, LAME’s implementation is better than the ISO one) at highest algorithmic quality (
-q 0
) and medium-to-high VBR quality (
-V 2
). This results in 160 to 180 kbps, on average, with most of my music, sometimes more. In general it is indistinguishable from CD, using my headphones (Sony WH-1000XM3 and Cambridge Audio Melomania 1). If that’s not enough for you, you can set the VBR quality to 1 or even 0; this will produce larger files (higher average bitrate). If your music makes excessive use of stereo effects (some psychedelic music does that, for example), you should use left-right mode (
-m s
) instead of joint-stereo mode. And if you’re truly paranoid, you can encode at 320 kbps CBR. This will produce even larger files, but they will still be much smaller than uncompressed WAV files.
