How can a sine sweep be useful when measuring a room?
The use of sine sweeps is a robust method to measure room impulse responses. One particular advantage is that the frequency spectrum of the excitation signal can be con- trolled in the time domain – by changing the rate of fre- quency change – while keeping the amplitude of the signal virtually constant over time.
What is a sine wave sweep?
Therefore, a sine sweep is a sine wave that increases (or decreases) in a smooth manner over the duration of the signal. There are two classes of sine sweeps: Linear Sine Sweeps and Logarithmic Sine Sweeps. Sometimes these are also known as chirps.
