View Full Version : combining .mp3 files

Is there a good app to combine two .mp3 files to make one soundtrack for an iPhoto slideshow? I don't think you can use more than one file for a slideshow created in iPhoto. I don't want the song to repeat and I want the slides to appear for more than 1 second.

I have used a program called HJSplit for Java (http://www.freebyte.com/hjsplit/). Check it out, this will work on OS X or any platform running Java. You can split or join multiple files. I have never joined two MP3's but I do not see why it would not work.

There is a great open source program called Audacity. Check out http://audacity.sourceforge.net

I'll second on audacity. It's a great little app that does a lot of nice sound editing. Unfortunately it still does not support AAC and needs a separate library (LAME) installed to support MP3, but instructions are on their site.

If you simply want to join two (or more) mp3's end to end, AND the settings are the same in each, you can simply cat them together in the terminal ( `cat file2.mp3 >> file1.mp3 #note that this command will change file1.mp3`). If the metatags are important it will mess things up a little as you only see the tags for the first file.

For the tags, it's even more confusing when you use acmes method:

You'll have tags from the first and the last mp3 if they have v1 and v2 tags, so you should definitely either strip or fix them.

I'd strip tags and cover-art before to be on the safe side.
