| dear Angelo (thanks for these great tools!)
I have a couple of questions:
1. Is there anything wrong if I use a sweep limited to 20-1000 Hz? I just wonder if the Aurora tools assume that one always uses sweeps between 20 and 20k Hz.
I'm characterizing tactile transducers and I'm only interested in frequencies below 1 kHz. I record the transducers' response with a measurement accelerometer (frequency response flat +/- 5% between 5-15000 Hz).
2. I usually measure simple vibration signals such as sine waves or band-passed noise, recording them as audio. The sensitivity specifications of the whole I/O chain are known, and making use of them I can easily obtain the corresponding values of acceleration in m/s^2. Of course for this to work, the first step is to make sure that the digital amplitudes in dBFS are meaningful. So my question is: does Aurora (namely, the convolution of sweep response with inverted sweep) alter in some way amplitudes?
