I now had a look at the link you provided, and there I saw that BSD-3- Clause and MIT were also mentioned. I had a closer look at the code, and I found two more exceptions: the libspeexdsp based rate plugin (under the pph directory) seems to be licensed under BSD-3-Clause, and rate-lav/gcd.h is licensed under MIT (rate-lav/rate_lavrate.c is LGPL, however). > The licensing is explained here: > > https://git.alsa-project.org/?p=alsa-plugins.git;a=blob;f=rate/rate_samplerate.c > > So this particluar rate plugin is licensed under GPL 2.0 "to follow the > license of libsamplerate", unless you have a commercial license to > libsamplerate.
