iSoundFile is a Cocoa frontend for libsndfile. It makes use of many of the features provided by this library and offers a comfortable GUI for them. The source code is released under the GPL. There is also support for file playback which supports CoreAudio for output and purely uses libsndfile's routines to read the contents of the file.

Features:

• Tab "info": On the info tab, basic information about the file is displayed. The playback section allows you to choose the mapping for left and right audio output routing.
• Tab "strings": On file formats which support it, the "strings" tab offers you a possibility to read and write them. If the file format doesn't support it, the tab will not be shown.
• Tab "BEXT": On file formats which support it, the "BEXT" tab offers you a possibility to read and write broadcast wave extension information. If the file format doesn't support it, the tab will not be shown.
• Tab "peak": To see the maximum peak values of each channel, open this tab. You will have to calculate this information once.
• Tab "convert": Here, you can convert the file into any other format libsndfile supoprts. See their website for detailed information.
