Hello All: Back once again for some more questions and I thank all that gave me a better understanding of VBR's and Bitrate. I have installed Foobar and its a great listening tool. I still prefer Media Monkey as its more user friendly, at least more friendly to me. I found it didn't have the latest version of lame installed since I was getting different bitrates in vbr mode when using mediamonkey vs foobar. I believe that the latest version of lame is is 3.99.5 I installed this into media monkey and have some strange results when encoding mp3's in vbr 0 mode. I understand that Bit Rate isn't always a means of measuring quality but I have seen some strange jumps in Bit Rate using the lastest version. I have no idea what the last version that was installed on Media Monkey, but I compared it to some songs that had the old encoder. I found what I thought were some unusual results. Here are some results of my bit rates and I will explain after I list them...

1. In VBR0 with old version of lame: Steely Dan's Black Cow=230kbps
2. Same setting with version 3.99.5 = 254kbps

1.VBRO old Version of lame-Cattle Decapatations "Testcular Manslaugther" = 298kbps
2.New 3.99.5 version=284kbps

I understand that bitrate doesnt always mean what it should when in vbr mode, but aren't these some strange jumps. Steely Dan gained 14bits. Cattle Decapatation lost 14 bits. Doesnt that seem odd? Is my version of lame good (i checked its not a beta) and if it isnt what version do people reccomend. I want the version that is going to be the most rock solid in VBR mode for me, since lame is choosing the quality for me. And a bonus question so to say: Does anyone have any scientific proof that a higher or lower average BR by lets say 15-20bits will make a difference. I understand BR isnt everything but the average does mean something. I was cruising along encoding, I know I am confused about this behavior.
PS---I reseached this version of lame, couldnt find anything about its reliability or anyone that had any problems, so if it was posted already in a previous forum, i applogize, I couldnt find anything on that particular version.
