- I think it would be nice to have some form of auto-attenuation (and also
auto normalize-to-peak or even amping/compressing), but to make it perfect wouldn't you have to scan all your files first, or could you make some setup for that ?
The expected mode of use would be that an appropriate setting would be learned the first time a song is played, and recalled when the song is played again.
Ok, but where would you store the info ? And would it be fast enough with large song-collections ? If you do this it would perhaps be good to put the plugin in a "learn"-mode so you could get the info from all your songs fast and write it in a file for later use.
I have testet some files and they typically have clipping about 1db, but i found one file with 6db clipping in one sample (?), and if you auto-attenuate that the result is not good, so you should have some form of setup to prevent that.
This is a good point, but also a tough decision... how much clipping is acceptable?
Are there any audio technicians on the list (Anthony? :) who could go into details with me about sound energy levels, compression, normalization, etc.?
I found another file with a few (160 ?) samples with 8db clipping so i think that some kind of setup would be nice!
Thanks, Peter

The setting would probably either be stored in an RVA2 ID3 tag frame or in the registry. A setting would only need to be saved if it is not 0 dB.
It's not clear what "fast enough" means; I don't think there would be a separate "learn" mode -- the plug-in would always be learning as long as the automatic clipping attenuation option is enabled.

Maybe the right thing to do is limit the amount of automatic attenuation? You could then configure the maximum attenuation level to, say, 4 dB or whatever.

from the winamp plugin:

At least 1 decimal would be better (->1.9 MB)

Can I use MAD in Winamp to create .wav files for burning to cd or does Winamp somehow default to the FhG garbage for that function?

Winamp will use the same input plug-in (e.g. MAD) regardless of output plug-in. So yes, you can use MAD to create .wav files. Make sure you select the 16-bit output resolution if you want to put the result on audio CDs.
