Hey there if I play one single file with e.g. 30 seconds in it plays pretty much instantly. e.g.: play file1.mp3 trim 30 If I pass more than one file sox somehow takes much longer to seek to the desired position: play file1.mp3 file2.mp3 trim 30 I think modifying the command to: play file1.mp3 trim 30 ; play file2.mp3 works fine in most cases but it introduces an audible gap between the files. Is there a solution for gapless playback and fast trimming?
