Loop Editor 2 is a is powerful music loop editing tool developed by musicians and engineers for musicians and engineers.

Loop Editor is the perfect replacement for Apple Loops Utility. It supports all audio file formats that support loop points: AIFF Apple Loops, compressed & uncompressed CAF (AIFF, AAC & Apple Lossless) Apple Loops, AIFF, WAV, W64 and ACID. Additionally, Loop Editor supports forward, forward-backward, and backward looping. Loop Editor is one of the only applications available which supports sustain and release loops.

Loop Editor 2 allows you to view, add, edit and export Slices. It also supports advanced property editing capabilities such as the "Genre" and "Descriptors" properties for Apple Loops files.

The most important addition to Loop Editor 2 is full support for AppleScript. AppleScript makes Loop Editor even more powerful 
by allowing you to automate complex workflows and simplify the process of working with large numbers of files.


• Work with all audio file formats that support Loops
• Exports AIFF Apple Loops, compressed & uncompressed CAF (AIFF, AAC & Apple Lossless) Apple Loops, AIFF, WAV, W64 and ACID

Exactly what I needed, and then some

Rivera guitar amps are best

The documentation is sparse, but that’s because the interface is so well designed and intuitive. Why I needed this program, a problem it did solve, was that it was extremely difficult to make use of the large library of Sony Acid format wave loops that I had amassed before I switched from the Windows platform to Mac OS X. Now I can convert them to the format I need and retain all the critical information, like tempo, etc. The one thing I would like to see supported is a file format that Propellerhead introduced about a year ago. When an audio loop is exported from iOS by their Figure or Take applications, an AIFF file with tempo information is created. These files can be imported into Reason and it knows exactly the tempo used to create it, and so can adjust it to whatever is the tempo of the current project. Loop Editor does not use this information and indicates instead that the file has no tempo information. So, I wish Loop Editor could both read the data and add it to AIFF files it creates.

Could use some tidying up

Odat Huh?

The rex converter puts %20 in place of spaces in directory names, when batch converting. It’s a pain! Other than that I’m pretty satisfied.

immediately crashes


That's about it. Never got it to run once.

Follow up: I downloaded version 2.0 from the Audiofile web site and it launches, but is not licensed.

How do you get a refund from the app store? =(
