Sorry to bother you again. I made two recording choices:

mic: Earthworks M23; microphone amplifier: K&L kl GA PRE-73 JR, gain 35dB; recording code: rec_gui.py from sounddevices. The recorded audio is good and everything is normal
mic: Earthworks M23; sound card: Zen Go synergy core, gain 25dB; recording code: rec_gui.py from sounddevices. The recorded audio is "clipped". However, everything works fine when I use Audition software to record choice2.

Many thanks to you!

Sorry, I don't really know how to help here. The audio data is provided by the underlying PortAudio library, the Python bindings don't change the signal values.

Maybe the OS mixer levels are too high?
