[Solved] pulseaudio resampling question

When I dump the available resample methods in pulse, I don't see any of the src-* resampling methods. I would like to test with them, how do I make them available?

When I configure pulse to use src-sinc-best for instance, it reverts to the default speex-float-1.

I'm checking what is being used with pacmd --list-sink-inputs

Thanks!

Re: [Solved] pulseaudio resampling question

Support has been deprecated from pulseaudio and subsequently removed from the Arch package as they were unmaintained and testing showed there not to be any benefit compared to the speex-float resamplers in both quality and cpu usage. However there are now new soxr based resamplers which are of higher quality than the speex resamplers but are currently having a bug that introduces a 20ms delay on everything

If you still want to test them, you can rebuild the pulseaudio package with support added in again (there's a --disable-samplerate or similar flag which needs to be removed)

Re: [Solved] pulseaudio resampling question

Thanks, no need to recompile pulse, it's not that important. I just wanted to try it out,that's all.

I'll look into the sox based resamplers instead.
