The default threshold for silence is -48db, but this threshold is very much dependent on the mp3. How can I determine the correct threshold? At the moment, I'm running mp3splt -s multiple times with different threshold values. If mp3splt cannot find any silences, I know the threshold is too low. So i try a higher threshold.
th=-48, th=-36, (no silences)
th=-24 (lots of silences)
Then i use this threshold (or continue to look between -24 and -36 for a better value) to split with -t.
Any of the following would help:
mp3splt determines a suitable silence threshold automatically by analyzing the entire track and looking for minimal levels. The user then reruns mp3splt using this threshold.
mp3splt -t -a doesn't require a threshold value, but looks for the "most silent" interval in the range, i.e. the interval with the lowest maximum volume.
E.g. Using "mp3splt -t 5.0 -a -p gap=30,min=1 ..."
would search for a silent interval of length 1 second somewhere in the interval 4.30 to 5.30, and make the split according to this.
