[vorbis] (Un)Usefulness of Vorbisgain?

[Erik Stenborg]

I will quote Frank Klemm:

Overload is a problem of all gadgets which do audio processing.
These are lossy codec and also the processing inside ever D/A converter.

Download http://www.uni-jena.de/~pfk/mpp/audio2/overloadtest.zip
unpack it and

listen to the WAV directly
encode it with mppenc and listen with "mppdec"
... listen with "mppdec --scale 0.5"

end quote

Try to play this file at full scale and then halve the volume with some
audio editor (CEP or whatever) and listen again.
