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
- 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
- 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
- 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
- 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
- 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.
