A/B Sense - Compare two versions of a song

When mastering, it can be difficult to compare your music choices, without switching back and forth between the two songs and manually seeking in a music playing app.

Using A/B Sense, it's possible to load up mutliple tracks and have a single playhead, so that way you can easily switch (with N on the keyboard) between two or more versions of a song.

You can also highlight regions to auto-loop, to really dive in and inspect individual choruses or solo's.

As a non-music producer, the app is also useful to compare quality across different speaker types. For example, loading a lossless .FLAC file and checking it against a compressed 320Kbps MP3.
