Making multiple versions with volume differentials

[chrisjj]

What is the best way to convert from a single input file to multiple output files each having volume normalised to ReplayGain /plus/ adjusted by a different differential? E.g.

out1 ReplayGain + 6dB
out2 ReplayGain
out3 ReplayGain - 6dB
out4 ReplayGain - 12dB

To minimise execution time and maximise output quality, I would like to avoid redundant ReplayGain calculation and transcoding.

Thanks.

You would calculate RG and store in the ID Tags (utitlity codec [ReplayGain]).

Then you would convert the file >> Multi Encoder and use ReplayGain (apply).

Thanks. Where best to apply the differential?

1st Pass (batch converter) calc replaygain,
2nd Pass use Multi Encoder, and use the DSP effect volume normalize (use it twice, one with replaygain and one with the fixed amplification).

Ah, neat. Thanks.
