Hello,
I've done a measurement session that was OK from the measurement part (OK range) and bad from the filtered result.
After listening to SweepMeasurementFile i've found that there is click/pop noise in the measurement file.
This session was done with 6.16:
- Motu 8A ASIO (not working in WASAPI mode)
- UMIK-1 in WASAPI exclusive
I've then tried to understand why my measurements where bad so I've done a test with another soundcard:
- VLINK 192 (USB audio class 2 to DAC) in WASAPI exclusive mode (no ASIO) (set to 48khz 24bits)
- UMIK-1 in WASAPI exclusive
Same things lot of click / pop...
It is coming from the playback as I heard them (not heard during my playback on the Motu with ASIO).
I've tried to put audiolense in realtime prioty and it changes nothing.
I've changed output to Realteak (WASAPI) same click / pop.
I've tried with directsound for playback / recording and it works.
I've done it again with the Motu in ASIO and no pop noise heard but there is pop noise in the recording this time (WASAPI Umik) ....
To sum up WASAPI seems to be broken with audiolense on my side...
I've also a strange hole at 10KHZ at -19db that was not there on my previous measurement.
