Does Replay gain work differtly in Media monkey, Foobar and Media Monkey given 2 differnt Results Options

[jimmanningjr]

Hey Anyone,
For the past 2 years I have been using Media Monkey to Organize and play my music collection which is now about 42,000 tracks about 75% of my collection has Replay gain Values....I am making the switch over to Foobar2000 and was about to replay gain the other 25% with it (Foobar) when I discovered that for the same album I was getting 2 different values...and it is making me wonder does Media Monkey use a different algorithm or is there something I am overlooking...both are set to tag by ALBUM with the track value put in there also. Here are my results:

Miles Davis /Jack Johnson Soundtrack/
Trk1 Right Off -FOOBAR--Album Gain -1.97db Trk Gain -2.49db
Trk 2 Yesternow-FOOBAR Album Gain -1.97db Trk Gain -0.87db

Trk 1 Right Off Media monkey--Album Vol=-7.9db Trk Vol= -8.4db
Trk 2 Yesternow Media Monkey--Album Vol= -7.9db Trk Vol= - 6.8db

Could someone shed some light on this for me.
Thank You

I had to register here to say thank as well! I am a MM user for the last 3-4 years and was curious as to what(if any) differences were with MM, Replay Gain/MP3 Gain.

I had posted a question on MM forums right before we left for Hawaii, and my question branched off a bit. Here: http://www.mediamonkey.com/forum/viewtopic...f=1&t=52653

David's Q & A session on this thread seemed to answer most of my questions as well. Although, can MP3 Gain(Level Track Volume in MM) be done more than once to a track or is it better to go to a different db level from the original untouched tracks? I was thinking of going from 89db currently to 93db.

Thanks, and thanks to the OP for starting this thread!

... can MP3 Gain(Level Track Volume in MM) be done more than once to a track or is it better to go to a different db level from the original untouched tracks?

With mp3s, there's no advantage to going back to the original tracks. Unless something goes wrong (software bug), or you use utterly stupid numbers (a target of several 100 dBs), you'll get the same result going straight to 93dB as you will applying a different target level first.

One caveat: if you use Album Gain for the latest gain change, then you must have also used Album Gain for any previous gain changes. If you apply Track gain first, and then try to apply Album again, it won't be right. You'll have to go back to the original files to get the right Album gain applied (unless the application stores "undo" information when you apply the Track Gain first time, and uses it when calculating the Album gain - I don't know if this happens or not).

Hope this helps.

Cheers,
David.
