some errors throw during infer, and output file generated is bad quality

Finish inference. Check output1.mp3

Although I get an output file, the sound has lots of artefacts/noise and is not smooth at all. I see some warnings and errors in the console output, are they the cause? or is it the models I am using?

Also how to get the output combined with the instrumental when using music audio?

Thanks,
