So, Lord "Objective-C" Swift's binary blob size is harder to beat than Quake?

Assuming for the sake of argument that playing back mp3s during gameplay is beyond this device, resampling the wav files to halve the sampling rate when extracting them certainly isn't. You'd get half the storage back, the audio presumably wouldn't suck any worse than it already does on that little device, and it should all work since the 44.1Khz sampling rate isn't baked into the wav file standard (but who cares, you've got the Quake source code anyhow).

It'd be an interesting exercise to see how much you could lower the sample rate without it sucking. On second thought, you could convert stereo to mono first, without even worrying about the sampling rate, and get half the space back. But I'm sure you could do more.
