Since your input LRA is 9.4, and output LRA is 7 (default), the filter will upsample to 192 kHz. You should resample afterwards.


Ok, whats the correct way to do that?

e.g.

    ffmpeg -i input -af loudnorm=...,aresample=48000 output

Ideally, loudnorm should call a resampler internally, but for now, this is what we can do.

Thanks,
