While this is quite fast on x86 (order of a few microseconds), the computation can take a few milliseconds on ARM (measured at 1.9ms (32000 -> 48000) and 3.3ms (32000 -> 44100) on a Cortex A53). Let's precompute some common rates so that we can avoid this overhead on each stream (or any other audioconvert) instantiation. The approach taken here is to write a little program to create the resampler instance, and run that on the host at compile-time to generate some common rate conversions. |
