description: Process audio using a SoX effect.
bugs:
  - Some effects are stereo only, but MLT processes each channel separately.
  - Some effects have a temporal side-effect that do not work well.

            [-e|-b|-B|-r] [-n] [-l|-h] [gain-dB]
            -e    Equalise channels: peak to that with max peak;
            -B    Balance channels: rms to that with max rms; no clip protection
            -b    Balance channels: rms to that with max rms; clip protection
                  Note -Bn = -bn
            -r    Reclaim headroom (as much as possible without clipping); see -h
            -n    Norm file to 0dBfs(output precision); gain-dB, if present, usually <0
            -l    Use simple limiter
            -h    Apply attenuation for headroom for subsequent effects; gain-dB, if
                  present, is subject to reclaim by a subsequent gain -r
            gain-dB    Apply gain in dB
