permalink Why did I get 2-channel audio? I asked for mono.

That's a bug, and we'll have it fixed soon. A library in our toolchain always reports AAC audio as 2-channel, even if it is mono. If you want to verify this for yourself, download the offending file, open it up in iTunes, and call "Get Info" on the file. It should report the correct number of channels.
