DSP
Digital signal processing means the creation of sound effects via digital processing.
It requires:
- MCU: a microcontroller like arduino or ESP32
- DAC/ADC: digital to analog and analog to digital, at least 12bits
- control:
- analog: GPIO
- midi: with opto-cuopler
axoloti
Axoloti is a DSP programmable board.
We build an axoloti pedal and program the effect bank.
Pedal
Axoloti connected to a button pedal via ethernet cable
We put a display, buttons and poti in the case
We build an axoloti controller pedal plus controls in the case. We program the effect bank.
We connect two buttons, two potis, a display and two ethernet ports for the pedals
We build a pedal with 6 buttons and an expression (from a gaming joystick)
We program the effect bank and push it to github>
We connect the pedal to the axoloti and the music box.
