Using this device on Mac OS X 10.9, analog video input shows up as a system device. It also works as a firewire video output device.

Input

 

Using Jitter you can get real time input from analog video devices like cameras and VCR’s. Here’s an example using jit.grab (Max help file) to get input from an analog camcorder.

Output

Sending output via firewire to a TV using jit.qt.videoout (Jitter tutorial 22):

This is what it looks like on a TV:

Google+ hangouts studio mode

(update)  The studio mode option in Hangouts only appears on the settings menu after you have checked ‘hangouts on air’ and then actually started the Hangout. Only then can you goto settings (gear icon) and select studio mode.

Raspberry Pi with Pd: audio test

notes

In an audio pass-through test using Pd, with a USB sound card (Griffin iMic), the maximum stereo sample rate before ‘breakup’ is 32000.In mono, it sounds “ok” at 44100. Latency seems low enough to use for music but I’m too sleepy to figure out the numbers.

I don’t know enough about Linux audio to say if the performance deficit is due to ALSA drivers, the sound card, background processes, pd, the CPU, or what?Anyway I ‘m guessing R-Pi will spawn interesting synths and lo-fi FX processors. They’re cheap enough you could use them in parallel.

Prediction: They’ll double the speed, and sell a million more by the end of the year. We’ll see a range of ‘Pi’ clones which run the same Linux distributions, but offer various speeds and IO options. It feels like the democratization of manufacturing has taken another huge leap.
