The `gain' effect seems superior as it can "see" across the effects chain to take into account extra/lost headroom. For example, this allows me to add the the "gain -h" effect at the start of my effects chain before the RGFX placeholder in my source command, so when I play a file requiring a -6dB ReplayGain adjustment, I will only need an additional -4dB of headroom to accomodate the 10dB boost at 20Hz I use (for listening through headphones): Before: RGFX='vol -6dB' sox "$INFILE" $SOXFMT - $TRIMFX $RGFX vol -10dB equalizer 20 0.7071q 10 After: RGFX='gain -6' sox "$INFILE" $SOXFMT - $TRIMFX gain -h $RGFX equalizer 20 0.7071q 10
