Plugin List

  • Oscillator - Multi-waveform audio signal generator with precise frequency control

Oscillator

A versatile audio signal generator that produces various waveforms with precise frequency control. Perfect for testing audio systems, creating reference tones, or experimenting with sound synthesis.

Features

  • Multiple waveform types:
    • Pure sine wave for reference tones
    • Square wave for rich harmonic content
    • Triangle wave for softer harmonics
    • Sawtooth wave for bright timbres
    • White noise for system testing
    • Pink noise for acoustic measurements
  • Pulsed operation mode for burst testing and intermittent signals

Parameters

  • Frequency (Hz) - Controls the pitch of the generated tone (20 Hz to 96 kHz)
    • Low frequencies: Deep bass tones
    • Mid frequencies: Musical range
    • High frequencies: System testing
  • Volume (dB) - Adjusts output level (-96 dB to 0 dB)
    • Use lower values for reference tones
    • Higher values for system testing
  • Panning (L/R) - Controls stereo placement
    • Center: Equal in both channels
    • Left/Right: Channel balance testing
  • Waveform Type - Selects the type of signal
    • Sine: Clean reference tone
    • Square: Rich in odd harmonics
    • Triangle: Softer harmonic content
    • Sawtooth: Full harmonic series
    • White Noise: Equal energy per Hz
    • Pink Noise: Equal energy per octave
  • Mode - Controls signal generation pattern
    • Continuous: Standard uninterrupted signal generation
    • Pulsed: Intermittent signal with controllable timing
  • Interval (ms) - Time between pulse bursts in pulsed mode (100-2000 ms, step 10 ms)
    • Shorter intervals: Rapid pulse sequences
    • Longer intervals: Widely spaced pulses
    • Only active when Mode is set to Pulsed
  • Width (ms) - Duration of pulse ramp time in pulsed mode (2-100 ms, step 1 ms)
    • Controls the fade-in/fade-out time of each pulse
    • Shorter widths: Sharp pulse edges
    • Longer widths: Smoother pulse transitions
    • Only active when Mode is set to Pulsed

Example Uses

  1. Speaker Testing

    • Determine minimum audible volume
      • Test different frequencies at varying volumes
      • Map personal equal-loudness contours
    • Temporal processing evaluation
      • Use pulsed mode with varying intervals to test temporal resolution
  5. System Calibration
    • Level matching between components
      • Use sine waves at reference frequencies
      • Ensure consistent levels across the signal chain
    • Channel balance verification
