I have 100 music I want to make a playlist. At each end of a song I want to make the effect “cross fade out”. And the beginning of each song I want to make the effect “cross fade in”. I can do it manually but 100 files it’s very long. Is there a method to do it automatically or faster than one by one.
Winamp (now pretty-much orphanware) has crossfading (which you access through the equalizer). I’m pretty sure Windows Media Player and iTunes also have it as an option.
[u]SqrSoft[/u] has a free “smart” crossfading plug-in for Winamp. It analyzes the file volume, so you can start the crossfade when the current song fades to a pre-set level, etc. Or, you can do a “smart DJ style” crossfade where the songs overlap with no additional fading. when the “natural” fade-out hits a preset level. …But, I get glitches with it. I believe Media Monkey supports Winamp plug-ins, but I haven’t tried it.
There are also some DJ applications that can do an automatic smart crossfade.
