No more coconuts.
Like most apps from Rogue Amoeba, it's a fairly powerful tool with a smart and friendly interface, and you can try it out free before you shell out $US49 ($64) for a licence (currently on sale for $US39 ($51)).
Using the app, I was able to whip up an Arrested Development soundboard by dragging audio files from Finder (and from Chrome's download pane) onto the app. Each instantly got an associated keyboard key, which I could change by moving the sound sample around the app window. I even custom-built a loop using the very basic waveform editor on the right pane.
As with other Rogue Amoeba apps, your Farrago licence covers installations on multiple machines, so you can stick it on your laptop, desktop, and work computer. The app automatically saves the sound sets you build, as well as copies of the sounds themselves, so you don't need to shuttle files around.
If you just want a couple funny fart sounds for your podcast, use a free website. But if you want more control, try Farrago.
