Code: Select all
calib_in.peaklevel=[120 120]
But the calibration is wrong for my set-up and I have to increase the input peak level to:
Code: Select all
calib_in.peaklevel=[135 135]
1) How can I check with MHA, if peak clipping occurs in the input chain?
I recorded now the direct input signal with audacity and can see, that my whistle is not clipping. But this does not check if my settings in the MHA might cause peak clipping. That's already my solution to check this, although I would prefer a solution, where I am able to check this directly in the MHA.
2) Any ideas how I can check with MHA if peak clipping occurs in the input chain?
Last question: If I configure the MHA to a low calibration value (low mic sensitivity) and add e.g. 20 dB of gain so that a sine with 80 dB SPL input level (full scale) have an amplitude above "1". Will this signal be clipped by the MHA or can the MHA internally process signals with amplitudes larger than 1 dB FS? The output calibration might be sufficient to play back the sine with 100 dB SPL:
Code: Select all
calib_in.peaklevel=[80 80]
calib_out.peaklevel=[120 120]
