Re: [SoX-users] using sox to do simple cross-fade? or some other tool?

[Chris B. <ch...@cn...>]

There is no single effect in SoX to do this but it contains enough 
building blocks to get it done.  Please see 
http://sox.sourceforge.net/Docs/Scripts for some sample script 
(crossfade_cat.sh) that will do cross fading and result in a single 
file.  You can do this multiple times to keep appending and cross fading 
new files to the end.
