Description

A ring modulator that multiplies audio inputs by a modulation signal with a dry/wet mix control. Supports multi-channel audio via the query system.

Parameters

Dynamic count (N = number of audio channels):

# Name Type I/O Details
0..N-1 in 1, in 2, ... ptAudio Input Audio inputs
N..2N-1 out 1, out 2, ... ptAudio Output (ReadOnly) Audio outputs
2N mod ptAudio Input Modulation signal
2N+1 mix ptDataFader Input Dry/wet mix (0–1, default 0.5)

How It Works

  • onCallBack: Stores mix coefficient in std::atomic<float>
  • onProcess: For each channel: output = input * (1-mix) + (input * mod) * mix
  • Uses createEvent for a temporary multiplication buffer

Key Concepts Demonstrated

  • Ring modulation via event multiplication
  • Temporary events with createEvent/destroyEvent
  • Dry/wet mixing pattern
  • std::atomic for thread-safe parameter sharing
