Sirp is a computer program for measurement on loudspeakers. Sirp can be used to measure the acoustic frequency response, and use a gating technique that eliminates the room reflections at high frequencies. Sirp uses logarithmic sine sweeps and derives the impulse response of the system from the response to the log sweep. Using a special technique also harmonic distortion can be measured for the entire frequency range, using just a single sweep of a few seconds. Sirp can also be used to measure the electrical impedance of the loudspeaker as a function of frequency.
Response data from Sirp can be imported into Basta! versions 220.127.116.11 and higher.
