How to measure impulse responses with the Sine Sweep, guide for correct I.R. measurements

No problem.
For STI measurements, I usually employ a Bruel & Kjaer 2250 SLM, which records the full WAV file of the microphone signals.
It is not connected in any way with the computer generating the test signals being sent to the artificial mouth.
Typically, I create a sound file containing:

- 30s of equalized pink noise
- 30s of silence
- 30s of exponential sine sweep (25s of sweep, 5s of silence).

Then I play-loop the file continuosly.

While it is playing, I go around the room, and in each position I record on the SLM the complete 90s-long sequence.
Later one, processing the three 30s-segments I get the three required sound samples for computing STI (Signal+Noise, Noise and Impulse Response).
