How to take fast impulse response measurements in Smaart© without pissing people off
Use these settings to efficiently investigate room modes with the impulse response module in Smaart©. FFT: 128kAvg: NoneDelay: 0 (doesn't matter)Options > IR > Overlap: 0%Signal Generator: Pink noise, Pseudorandom, Drop IR Data WindowLevel: +10dB above noise floor Measuring room modes sucks. It takes too long, pisses people off, and the ROI is debatable. The last one is user dependent. Let's work on the first two. Why does it take too long? This was user error on my … [Read more...]
