speex-float-10 provides better quality than say speex-float-2 - higher values produce better quality and consume more CPU, lower values have lower quality and consume less CPU. soxr-vhq produces better audio quality than speex-float-10 but it is also more CPU-intensive. The difference in CPU power required to re-sample audio mattered in 2005 ...

I suggest changing the default resample-method to speex-float-10, instead of speex-float-1, which is the current default now, in /etc/pulse/daemon.conf. In my day-to-day usage, it gives better sound quality without sacrificing CPU power. I have always done that since at …

Your current config allows for “speex-float-1” resampling which is a bit hit to audio quality. Pulseaudio also likes to pick a sample rate and stay with it, re-sampling everything else. There are resamplers that do a pretty darn good job (SoX/SRC), but they use a fair about of CPU and on an embedded device that might not work well.

They exist in two flavours: fixed and float. The former uses fixed point numbers, the latter relies on floating point numbers. On most desktop CPUs the float point resampler is a lot faster, and it also offers slightly better quality. See the output of dump-resample-methods for a complete list of all available resamplers. Defaults to speex-float-1.
