As mentioned libcanberra does. But it might be the only one.

pa_stream_peek() will allow you to monitor the PCM data that is
actually written to the device, i.e. the end product of resampling/remixing,
volume adjustments and so on. Since we apply per-stream volumes before
we resample/remix it's a bit hard to give you the data unmodified.

Instead of monitoring particular sinks you can also monitor
particular sink inputs, which will give you the data without the sink
volume applied. (but with the sink input volume applied). To do use
pa_stream_set_monitor_stream().
