Other Audio Tools

A collection of specialized audio tools and generators that complement the main effect categories. These plugins provide unique capabilities for sound generation and audio experimentation.

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

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

Example Uses

1. Speaker Testing
   • Check frequency reproduction range
     • Use sine wave sweep from low to high frequencies
     • Note where sound becomes inaudible or distorted
   • Test distortion characteristics
     • Use pure sine waves at different frequencies
     • Listen for unwanted harmonics or distortion
     • Compare behavior at different volume levels
2. Room Acoustics Analysis
   • Identify standing waves
     • Use sine waves at suspected room mode frequencies
     • Move around the room to find nodes and antinodes
   • Check resonance and reverberation
     • Test different frequencies to find problematic resonances
     • Use pink noise to evaluate overall room response
   • Map frequency response at different positions
     • Use sine sweeps to check consistency across listening area
3. Headphone/Earphone Testing
   • Evaluate crosstalk between channels
     • Send signal to one channel only
     • Check for unwanted bleed into the other channel
   • Test frequency response
     • Use sine sweeps to check frequency balance
     • Compare left and right channel responses
4. Hearing Tests
   • Check personal hearing range
     • Sweep frequencies to find upper and lower limits
     • Note any frequency gaps or weaknesses
   • Determine minimum audible volume
     • Test different frequencies at varying volumes
     • Map personal equal-loudness contours
5. System Calibration
   • Level matching between components
     • Use sine waves at reference frequencies
     • Ensure consistent levels across the signal chain
   • Channel balance verification
     • Test left/right balance at different frequencies
     • Ensure proper stereo imaging

Remember: The Oscillator is a precision tool - start with lower volumes and increase gradually to avoid potential equipment damage or hearing fatigue.
