Hi all. I'm new to audacity, so I'm hoping people can help me learn to use it. There's a specific set of steps that I do to all my music files to sorta spruce them up. Those steps are:
- Normalize to an average loudness.
- Trim silence from the ends.
- Fade the beginning and the end.
- Save as a VBR MP3.
I also want to be able to run these commands in some kind of batch process. Can someone help me figure out how to do this with Audacity?

Re: How do I do these? : Normalize, trim silence, fade, and
Step 3 cannot be done as a batch as apply "fade out" or "fade in" will process the entire file, not just the ends. (Audacity does not know how much of the file you want to fade, so it assumes that it is the complete file).

Re: How do I do these? : Normalize, trim silence, fade, and
I wondered about the batch thing.
I don't think you can do most of that automatically.
Normalize will not operate to an average loudness. Normalize takes the highest peak value and puts it at the preference selected level dragging the rest of the song with it. If you combine two songs, one with high dynamic range and one highly compressed dance tune, the dance tune will come out enormously louder. There are no loudness tools that I know of.
You can compress the volume variations of the first tune to sound like a dance tune and then apply normalization. That will work a lot better. Compression settings tend to vary with the song, so you'll need to tune each song.
Trimming before and after silence depends on the settings of the silence detection. To my knowledge, no silent sense has ever worked right. It either wackes off the lead of the first note, or leaves long tails at the end. Sometimes it cuts holes in the middle of a song. You end up tuning each song which kind of defeats the purpose of batching.
The problems with fade were covered.
Anything else we can help you with?
