Sweep Tone Generator
Create frequency sweeps for audio testing and analysis
This sweep tone generator lets you test how a sound changes across a frequency range. It's an online frequency sweep generator that supports smooth transitions from any start to end frequency, making it perfect for testing speakers or headphones using sine sweep tones.
What Is a Frequency Sweep Generator?
A frequency sweep generator, also known as a sweep tone generator, produces a continuous tone that gradually changes in frequency over time. This tool is essential for audio testing, as it helps identify how speakers, rooms, and other audio equipment respond to different frequencies.
- Linear and logarithmic frequency sweeps from 20 Hz to 20 kHz
- Adjustable sweep duration from 1 to 30 seconds
- Multiple waveform options: Sine, Square, Triangle, and Sawtooth
- Precise volume control for safe testing
- Automatic sweep completion with smooth audio handling
How to Use This Sweep Tone Tool
Room Acoustics Analysis
Identify room modes, resonances, and acoustic problems. Logarithmic sweeps are particularly useful for revealing how your space responds across the frequency spectrum.
Speaker Testing
Evaluate speaker frequency response, detect resonances or distortions, and identify potential crossover issues. Use slow sweeps for detailed analysis or faster sweeps for quick assessments.
Audio Equipment Calibration
Test and calibrate audio equipment like equalizers, crossovers, and filters. Linear sweeps are ideal for testing time-based effects and processing equipment.
Sound System Troubleshooting
Quickly identify problem frequencies in sound systems. Use different waveforms to test how your system handles various types of audio content.
Understanding Sweep Types
Linear Sweeps
Changes frequency at a constant rate over time. Useful for testing time-based effects and when equal time needs to be spent at each frequency interval. Best for technical measurements and calibration.
Logarithmic Sweeps
Changes frequency exponentially, matching how we perceive sound. Spends proportionally more time in lower frequencies, making it ideal for room acoustics analysis and general audio testing.
Frequently Asked Questions
Important: Use appropriate hearing protection and maintain safe listening levels. Frequency sweeps can produce unexpected resonances and standing waves. Always monitor levels carefully and stop the test if you hear any distortion or excessive loudness.
