puriFIR

A Max/MSP port of Kallyn's puriFIR.

Go check the demo video because is super good and explains very clearly what this does.

I created this port because I'm not using FL Studio anymore since 2013 but really wanted to try this tool so this was the fastest solution. I guess it could be useful to other people too.

Pre-built Windows and Mac standalone applications and cross-platform Max For Live Audio Device are provided in the release section.

If you just want to make your own fork take a look at PuriFIR.ts, everything else is just to read and write buffers.

Overview

puriFIR is a tool for converting any sample into a minimum phase impulse response. Useful for techniques like "Color Bass" but probably has a million other use cases.

This version features:

• Basic sample import
• Region selection and cropping
• Processing with selectable window size
• Output impulse response export to audio file
• Drag and Drop for input and output files
