what is a good wave editor program? i would like one that can detect leading and trailing silence on tracks and delete them. eac doesnt always do a good job of that, and neither does its built in editor. also, the option to do this in batches would be great too.

IMO, the best audio editor is Samplitude 2496. But is's definetely not for newbies.

A good and easy editor is CoolEdit.

I also believe Cool Edit is a very good program. However I'm a heavy user of Sound Forge 6 and the Noise Reduction package. Unfortunately it isn't "bargain bin" priced. Just having either of the programs isn't enough ~ you must experiment with the options, read the help files and mutter "What do they mean by that", make a few bad mistakes and so forth to "get a handle" on what's happening. So called "Wave editors" can be generators of artifacts.

If you just want to delete leading and trailing silence, check out WavTrim (http://www.logiccell.com/~mp3trim/wavtrim.htm)
