Need Greatest Thing Since Canned Beer . . ., Change Long Track length? Options

[DBinNC]

I am looking for two features in a simple track editor to enhance the live shows I burn to CD:

1) Allow me to change the output volume of a song that is any given length. GarageBand can do this with Track Volume, but seems to only import the first 6:40 of a song. I often download live performances of tape-friendly bands where songs can run upwards of 20 minutes, but a track might contain 5 minutes of crowd noise at the beginnng (or end) of a song that I want to delete by tapering up/down the output volume.

2) Affect the EQ and compression output settings.

Since these discs are for my own enjoyment I am not looking to spend a lot of $$. Does anyone know of an inexpensive app that can do this? Name and web address of your suggestion would be greatly appreciated!!

Thanks in advance,
