plugin LV2 plugin URI.

-n frames
Number of audio frames to be processed at each cycle (default is 512).

-c port:value
Assigns value to the port identified by port symbol port. The specified port must
be a control input port and value must be a floating-point number in a form that
strtof(3) undestands, assuming that the "C" locale is being used.

Disables latency compensation that is generously offered to you by default.

Report some timing statistics on the standard output after sound processing.

Normalize the output file by applying the same gain factor to all channels. No
fancy loudness estimation going on here, just trying to make use of the whole
dynamic range of the output file format.


Used to override the list of directories where LV2 plugin bundles are looked for
(as per LV2 FHS, see <http://lv2plug.in/trac/wiki/Filesystem_Hierarchy_Standard>).
