I need to make videos where the audio incorporates only voice and occasional keyboard clicks (loud Cherry MX Blue keys).

My question: what's the best audio codec to choose for this? A mono 128mbps MP3 gives me 1 minute = 1 mb. A variable MP3 encoding set to 'low' gives me half that. But are there codecs which take up even less space and don't result in degraded quality?

Opus has been designed to cover very low bitrate encoding up to high quality sound. Definitely worth a try and a patent and royalty free codec.
