Reply to comment by CeFurkan in [D] Are there any AI model that I can use to improve very bad quality sound recording? Removing noise and improving overall quality by CeFurkan

The audio is a bit distorted possibly due to noise gating. I don't see too much noise, so maybe noise reduction is not what you need. The audio has 8 kHz bandwidth (16 kHz sample rate), maybe you may try to use an audio super-resolution network such as https://github.com/mindslab-ai/nuwave2 to increase the audio bandwidth.

yes i had tried some options obs back in time. it was probably noise gate. even i forgotten it.

thank you so much for reply gonna test that repo now

their example really good improvement but do i need training for that?

opened an issue thread but not much hope : https://github.com/mindslab-ai/nuwave2/issues/11

Just download the checkpoint and use the command at Inference session. sr should be 16000

Process with a sliding window would solve your problem, see e.g. https://colab.research.google.com/github/asteroid-team/asteroid/blob/master/notebooks/04_ProcessLargeAudioFiles.ipynb

thanks

no idea where to put this code in nuwave2
