the mixing matrix at runtime, without reinitializing the entire filter
chain.
-``drc[=method:target]``
- Applies dynamic range compression. This maximizes the volume by compressing
- the audio signal's dynamic range. (Formerly called ``volnorm``.)
-
- ``<method>``
- Sets the used method.
-
- 1
- Use a single sample to smooth the variations via the standard
- weighted mean over past samples (default).
- 2
- Use several samples to smooth the variations via the standard
- weighted mean over past samples.
-
- ``<target>``
- Sets the target amplitude as a fraction of the maximum for the sample
- type (default: 0.25).
-
- .. note::
-
- This filter can cause distortion with audio signals that have a very
- large dynamic range.
-
``scaletempo[=option1:option2:...]``
Scales audio tempo without altering pitch, optionally synced to playback
speed (default).
