FFAB unlocks the batch audio powers of the free ffmpeg with a GUI

FFmpeg, the free multimedia toolkit, is so powerful that, honestly, it’s entirely possible not to know all that it can do. For audio, the new FFAB offers a graphical front-end on Mac and Linux, with real-time preview, drag-and-drop filters, parallel processing, and useful visualizations that even command line lovers won’t want to miss.

Nasko’s completely free N-IRIS is a spectrum disperser – why that’s cool

Nasko, the prolific and imaginative software developer, is back with a new one – and it’s completely free, running in Plug Data (Pd) on Mac, Windows, and Linux. It’s a convolution-based spectrum disperser. Say what? Well, you get a powerful, precise, fairly rare method for generating impulse responses for convolution tools, like Kilohearts Convolution (now on sale), the one just added to Serum 2, and more. Or just play it live, because that also sounds kind of awesome.
