Thanks Fons. Do you have a recommendation for how much headroom to leave
before the conversion, and if you do clip during the conversion is there
any sort of warning? I used to leave around 1.5 dB. The way I used to
go about this was to apply all limiting to the 24-bit 48000 kHz track,
then SR convert, then normalize (to ~ -0.3 dB) or set a final level, and
finally dither/quantize.
I don't know about zresample but (if my memory doesn't fail me)
sndfile-resample automatically restarts in case of clipping and adds some
headroom.
