They're a bit tricky to learn but fmiser wrote some great posts: https://sourceforge.net/p/sox/mailman/message/23427259/ https://public-inbox.org/sox-users/20090829011522.cf27e6ee.fmiser@xxxxxxxxx/ For simple cases or a final pass after compand/mcompand; I like tap_limiter from the TAP-plugins LADSPA package: sox $IN $OUT ladspa -lr tap_limiter -4 3.5 (limit to -4dB, add 3.5dB gain) http://tap-plugins.sourceforge.net/ I usually use compand or mcompand for recordings which need a lot of correction. tap_limiter is good for recordings which only need a little correction, or after everything else (EQ, compand/mcompand, etc...) _______________________________________________ Sox-users mailing list Sox-users@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/sox-users
