Digital audio and video basics – two excellent videos

I’ve just come across two outstanding tutorial videos over on xiph.org – an open-source organisation dedicated to developing multimedia protocols and tools. So, the first one covers the fundamental principles of digital sampling for audio and video, and discusses sampling rates, bit depth and lots of other fun stuff – if you’ve ever wondered what a 16-bit, 128kbps mp3 is, this is for you.

The second one focusses on audio and gets on to some more advanced topics, about how audio behaves in the real world.

They’re both fairly long (30 mins and 23 mins respectively) but well worth watching. If you’re just getting started with digital audio and/or video editing and production, these could be really useful.

TTFN.

A primer on digital audio from Engadget

Another very quick link-out post I’m afraid ladies and gentleman – all this damn pushing back of the boundaries of science I’ve been doing lately has left me absolutely no time at all, plus have you ever tried pushing back a boundary? It’s bloody exhausting.

Anyway, following on from my recent post about the auditory gorillas experiment, where I talked a little about audio editing, I spotted a fantastic little piece over on Engadget about the basics of digital audio, covering things like sampling rates, bit-rate, file-formats and loads of other useful/mildly-nerdy stuff. In fact their whole ‘primed’ series (where they dissect common bits of computer technology from first principles) is well worth checking out.

Have a good weekend!
