Hi, Guys.
I'm working with the python api and i'm doing voice mailbox and tones detection (SIT tones) using a recorded file. From what i've seen, even after i've contrainted the codecs to be used, the wav file sample rate still is 8KHz.
 So, what my guess is the recorder is forcing this sample rate.
 There is a way to change this?

Python code to constraint the codecs:
core.audio_codecs = [c for c in core.audio_codecs if (c.channels == 1 and c.normal_bitrate > 16000 and c.normal_bitrate < 70000)]

I'm using version 3.9.1 in a windows 10 machine.
