Originally posted by tvmann MP3Gain is lossless. It modifies the "global gain" bits in the MP3 to adjust the level. The overall level can be adjusted in 1.5 db steps in this way. It doesn't do anything else. The track remains the same, it just plays back at a different level compared to the original, depending. MP3Gain does not compress the signal, which you seem to be saying. It is possible for a klutz to raise the level too high with MP3Gain so it will sound clipped, but if the "don't clip when doing Track Gain" option is used, no clipping will happen because the level will automatically be set lower. If you have found anything negative about MP3Gain, please post it. I don't think there is any negative information out there.

also if you havce analyzed track with MP3Gain, have you noticed that a lto of tracks they clip originally at the volume they are recorded.

I remember I had a plug-in for winamp, and it would analyze how many times the mp3 would clip, sometimes it was a few times, so if you get the db up by 1.5, at the first time they clip, they wouldn't do it that much.

of course this is not in all cases, but I remmeber when i tested the tracks, as you were upping the DB, the times that the tracks used to clip were a major number.

I think when people talk about 0 db it is more about analog line level signals, where the standard maximum level is considered to be 0 db. It don't know how this relates to levels on CDs.

Yes I noticed that too. About half the original tracks seem to have clipping according to the MP3Gain anaysis. I'm guessing here, but it probably means those tracks just barely hit the maximum level. They sounded OK. MP3Gain would reduce those track levels a bit to get rid of the clipping.

I'm also surprised that the MP3s showed any clipping at all. I'm using Exact Audio Copy / LAME which is the standard. Maybe there is a setting in Exact Audio Copy to set the level lower, so no clipping is possible.

***EDIT***
BTW here is another thread about the clipping, basically they recommend using MP3Gain to clean this up, it can happen when you make a MP3 from a heavily compressed & loud CD like from a lot of modern/electronic music:

Thanks, I'll check it out.

anyways when it barely hits the maximum level its not a big concern to me.

but let's sya I have a track sounding at 96 DB

and I have a track that is recroder and clipping at 91DB.

If I'm mixing, I would have to increase the gain volume from the mixer a lot to reach the other volume, it will be clipping a lot.

it's seems to me that If I change the gain with mp3 gain, it would be the same as changing the gain when live mixing.

I don't like track when they clip at 92 db, I like to have them from 94 DB to 96 DB, that's what seems to be standard.
