Build

• Install Daisy Toolchain
• git submodule update --init --recursive
• cd Aurora-SDK; sh ci/build_libs.sh; cd ..
• make
• copy FrequencyBands.bin from build folder to your device USB and reboot it!

Usage

All six knobs are CV-controllable!

FFT Controls:

• Warp: offset FFT bands (=multiple bins) by a number of bins
• Blur: Change number of bins in each band
• Mix: 0-50%: attenuate the bands between 0-100%.
• Mix: 50-100%: Boost the bands between 100-800% (the waveform is also normalized here not to clip, the result currently is it is a lot more silent in this case)

Comb filter controls:

• Time: delay time in samples (1-16k)
• Reflect: feedback
• Atmosphere: TiltEQ, clock-wise to hipass, ccw to lowpass

I/O section

This part could use some more work, right now its essentially only working Left in --> Left out.

• L out: Wet signal
• R out: Unaffected Dry signal
• L in: Used for everything
• R in: Used for nothing!

The code could be a lot more optimized! New features could hence be added pretty easily.

Get it

Prebuilt firmware binary is the file FrequencyBands.bin just grab it an drop onto the device USB
