What are you trying to achieve?: Microphone recording does not work in the Macbook pro
What did you try to make it work?:
Audio recording via the microphone component
What specifically went wrong when you tried that?:
Silent (blank) audio clip was generated and did not record any sound.
Here’s my diagnostic steps to debug/solve the issue
Microphone recording does not work in the Macbook Pro, so I debugged into the microphone component (microphone.py):
- Printed out
- Audio input devices returned ‘Microsoft Sound Mapper - Input’ as channel 0
- Noticed that by default, chnl parameter from AdvAudioCapture is always 0 when generated by experiment builder.
- Located the correct input device ‘Internal Microphone (Cirrus Log’ in the log, changed the code to define the chnl parameter to be ‘1’.
- Audio recording starts working
Note: The computer audio input device is set to ‘Internal Microphone’, I am sure of that.
Is it possible to introduce a text field for ‘Channel’ in the Mic properties in the next release?
The text field will auto generate the ‘chnl’ parameter in the AdvAudioCapture method.
I went ahead in my installation of Psychopy3 and updated the builder code/interface and it seems to work fine for me.
I’ve been searching around and I’ve noticed a common theme when people complains of audio not working, it’s to do with devices not matching the required channel.
Do let me know if this is a good idea?
Edit: Tested the same change in Mac mode and audio fails to record
