View Full Version : A question about the AGC option in JetAudio 5
I understand that AGC is Automatic Gain Control, and it normalizes the volume when playing files. However, what is AGC level? In JetAudio, AGC level is a slider which goes from 0 to 10.
...However, what is AGC level?...
What you said about the gain control is absolute right: it normalizes. With the slider you can choose the dimension of normalisation because, if you have different compressed audio files,e.g. files with different qualities (kbps) or encoded with different encoders, then you have a different scale of loudness of the compressed music. And in many cases that's the reason why a e.g. MP3 file is louder than the uncompressed file. I never tried it but I think it makes sense when you turn the slider up that it turns the loudness of your files down. I use for normalisation MP3Gain (http://www.geocities.com/mp3gain/), it normalized without deficit in quality but you have to do this before playing your files...maybe a disadvantage.
But I think there is one interesting question more about this. Does the gain control in JetAudio bring all files on one loudness or reduce it all files at a special value depending on their basic loudness?
