What is a sine sweep?
A sine sweep is a sine function that gradually changes frequency over time. The sine sweep can also be called "sinusoidal sweep," "frequency sweep", or "chirp".
How do you measure impulse response?
The simplest way of measuring an impulse response is often the use of an impulsive source signal such as a clap of your hands, a balloon or a blank pistol. By selecting External Impulse, the response to an impulsive signal is simply recorded without any subsequent processing.
What are the practical methods for measuring impulse response of an acoustic space?
The impulse response of an acoustical space or transducer is one of their most important characterization. In order to perform the measurement of their impulse responses, four of the most suited methods are compared : MLS (Maximum Length Sequence), IRS (Inverse Repeated Sequence), Time-Stretched Pulses and SineSweep.
What is log chirp?
The log-sine chirp is. essentially a sine wave whose frequency increases. exponentially with time (e.g. doubles in frequency.
