calf2lv

calf2lv.py generates an ecasound command line from the xml file created by calfjackhost GUI

With it, you can tune your filter using the powerful GUI, then use it on a headless system with lower specs.

The provided calf.xml file is a reasonable effect for an AM radio: it gives you a filter, a compressor, and a limiter. They are meant to be used in exactly that order.

You can generate a command line with python calf2lv.py calf.xml filter comp limiter.

To make it even easier, use --exec, which will actually run the effect as a stream.

A complete usecase is provided in lv.liq: run liquidsoap, with mono downmixing, which uses ecasound (through calf2lv.py) and aplay to actually play audio.

Install

calf2lv requires python3.

On debian

apt install python3 calf-plugins ecasound lilv-tools liquidsoap

enjoy!
