Generating MFCC with custom sample rate, duration and interval

[sa-paul]

Installing dependent libraries:

I have installed these libraries using these commands.

Errors while running actual code:

OSError: PortAudio library not found

Steps to resolve the errors:

1. I have done these same steps in my local computer with ubuntu 22.04.
2. The same error is showing there also
3. I have searched for the error in google.
4. I found that pyaudio is to be used instead of sounddevice [ Reference ]
5. I have implemented the same but got many errors which is library specific.

6. So, I sticked to sounddevice but tried another method to run through this library. [ References ]

7. But, got another error.

9. I have modified the code, but the error is same.

   Code:

   

   Error:

   

10. I have searched for the error Error querying device -1 but got no implication to my code. [ References ]

Error querying device denotes the inability to access the sound device/microphone. Make sure all drivers are properly installed. This is expected error in case of colab as it cannot mock an audio device input. This progress is good. You can now try performing the same tasks but now on on Arduino board.
