This is a tool intended to apply an LV2 plugin with a specific set of settings to an audio file. It supports any type of input file supported by libsndfile. The output format is FLAC 24 bit.
I needed something to run a limiter on a bunch of files and so I wrote this to use the Calf Multiband Limiter. All the LV2 port related stuff is hard coded, so it's not particulary good practice, but I wanted to get it done quickly and it worked for me.
Usage:
$ audiomaster <input.wav> <output.wav>
