sam here thanks for responding stereo depth perception is a term i came up with to explain what i'm hearing with flac compression level 4 compared to wave and all other flac compression levels which have stereo + mono depth perception making the audio sound 2 dimensional and flac 4 sounding 3 dimensional. i also hear this three dimensional sound on vintage vinyl.
i have tested this with foobar2000 / jriver media center 23 / audacity 2.1.0 / weiss saracon 1.61.27 / sony soundforge pro 10 / free audio converter 6.5 / using a dell pc running windows 7. played back the audio using both windows pc and sandisc mp3 player and the results are the same. re-encoding audio to flac compression level 4 converts the audio to sound like vintage vinyl.
