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.
In theory there is no limit to the inter-sample peak level.
It *could* matter for some technical test signals etc. For
normal music signals even 0.5 dB should be enough, and even
if it clips you very probably won't notice.
