NAME¶

lv2proc - a simple command line effect processor using LV2 plugins

SYNOPSIS¶

lv2proc [ options ] -i input -o output plugin
lv2proc -h|--help
lv2proc --version

DESCRIPTION¶

lv2proc generates an output sound file by applying a LV2 effect plugin to an input sound file.

OPTIONS¶

-h, --help

Print a short description of the command line options on the standard output and quit.

--version

Print version and copyright information on the standard output and quit.

-i input

Indicates the input sound file.

-o output

Indicates the output sound file.

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.

--with-latency

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

--timing

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

--normalize

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.

ENVIRONMENT¶

LV2_PATH

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>).
