Why does Lame's CBR and ABR modes reduce the amplutude of the sound data by 0.44 dB (RMS) while VBR "tries" to preserve it and "succeeds". Can I turn it off? Thanks.
use "--scale 1.0" option with ABR/CBR encoding.
Regarding "why", this is to prevent occasionnal clipping on the decoder side.
Thank you very much for your replies.
But this scaling does not fix the clipping problem because: - usually clipping (if there is any) happens to be greater than this value or there might be no clipping at all depending on the source material (already clipped/square wave-like or quite silent), - clipping may also occur when using VBR.
Even I don't have a single scaling value (used even 0.75), not to mention the great variety of sound material out there.
A note about the default value for "scale" in --longhelp or switchs.html would be nice.
