Dropsound was made to fill the void left by SoundApp, which was not ported to OS X. It is designed for previewing samples, which can be dropped one at a time, or many at a time, onto the main window. Each file is placed in a queue, which can be played through in sequence, if you like, and clear itself when at its end. Dropsound is powered by Quicktime, so it can play anything that QT can, including AIFF's, WAV's, and MP3's. These files can be played at half speed, double speed, backwards, or be looped, through the S, D, A, and L keys, respectively. By pressing the small triangle in the lower left of the window, you also get a little bit of info about the file (more info will be shown in later versions). Personally, I really like Dropsound, and other people seem to, as well. I've heard nothing but good things from all who've tried it. It's small, quick, simple, and completely free, so what's not to like? |
