af_drc: remove
Remove low quality drc filter. Anyone whishing to have dynamic range compression should use the much more powerful acompressor ffmpeg filter: mpv --af=lavfi=[acompressor] INPUT Or with parameters: mpv --af=lavfi=[acompressor=threshold=-25dB:ratio=3:makeup=8dB] INPUT Refer to https://ffmpeg.org/ffmpeg-filters.html#acompressor for a full list of supported parameters.

--- This script enables live control of the dynamic range compression
--- (drc) audio filter while the video is playing back. This can be
--- useful to avoid having to stop and restart mpv to adjust filter
--- parameters. See the entry for "drc" under the "AUDIO FILTERS"
--- section of the man page for a complete description of the filter.
---
--- This script registers the key-binding "\" to toggle the filter between
---
--- * off
--- * method=1 (single-sample smoothing)
--- * method=2 (multi-sample smoothing)
---
--- It registers the keybindings ctrl+9/ctrl+0 to decrease/increase the
--- target ampltiude. These keys will insert the filter at the default
--- target amplitude of 0.25 if it was not previously present.
---
--- OSD feedback of the current filter state is displayed on pressing
--- each bound key.
