Thank you very much! And thanks for the great software! Cheers, tiki

Hello, I get audio data by an external digital PDM mic, connected to a STM microcontroller. This data is sent to the PC through a USB-COM-port with a selectable baudrate. Is REW able to process this data instead coming from a microphone? If yes, how do I have to set the REW configuration? If...

Thanks! For these measurements I used the Java drivers with 32k/32k buffers for the in-/outputs. Mostly there will be one usable measurement, if repeated. Cheers, Timo

Wow! Thank you for the quick update! Meanwhile I did some measurements on the transducer, see the attached pdf (in German), if interested. The software works fine for this application, except for some discontinuities from time to time. It can be observed by watching the "signal" LEDs at the...

Hello, The RTA measurement seems to show the correct levels. The Measurement was conducted using different gains in the RME input of 0 dB and +55dB, respectively. A hint regarding REW capture function: If the comment grows "too big", the dialog elements (especially the lower buttons) run out...

Hi, aha, the last remark points to the same direction. So only the sweep measurement is not suitable. I will try the RTA mode next time. Thank you very much! Cheers, Timo

Yes, I followed that (simple) order, described in the REW help. Before that I did the soundcard calibration. At least I believe, I did it right. ;) If REW produces an output (if not sine, it may be noise?), which should drive the sound source, this procedure may fail, because REW should expect...

Hello John, Thank you for the quick response! The soundcard calibration is done, see the attached screenshot. I tried this recommended SPL meter cal procedure several times with reproducible results. I did not use an REW/soundcard driven sound source but an independent SPL calibrator with a...

Hello all, I use as measuring equipment: - Microtech Gefell MK 221 (50mV/Pa) and MK 301 for ultrasound (4,5mV/Pa) with the appropriate preamp MV225P48 - RME Fireface UC (Line outputs 3/4, Mic inputs 1/2, gain 0dB) - SPL calibrator for the mics, giving 94dB SPL at 1kHz sine - Win10 PC Is there a...
