Description

if dynaudnorm could support a side-chain version (similar to acompressor) -

using an audio's peak is innacurate
but an upsampled-version of audio is closer to 'true-peak'

How would you normalize non-upsampled audio with upsampled one? That is just impossible.

comment:2 by mtc, 5 years ago

pretty-easy:
by applying the side-chain to a aevalsrc=1 , downsampling(non-sinc to avoid ringing) that to match original rate, and then multiplying that to original

that way you don't have to deal with resampling degrading original, unfortunately doesn't seem very simple :/

Then upsample prior to calling filter.
