What is a Frequency Sweep?
A frequency sweep (also known as a chirp) is a signal in which the frequency increases (up-sweep) or decreases (down-sweep) with time. This tool generates a continuous audio sine wave that glides from your chosen start frequency to the end frequency.
Common Uses
- Speaker Testing: Test your speakers or headphones for buzzing, rattling, or "dead spots" across the entire audio spectrum.
- Room Acoustics: Identify resonant frequencies in your room.
- Hearing Test: Find the upper limit of your hearing range (typically decreases with age).
- Subwoofer Test: A 20Hz to 100Hz sweep is perfect for testing bass response.
