Denoised audio 0db on NSDTSEA

zfqy opened this issue 6 years ago · comments

The training process starting with the code according to "readme.md" has been early terminated at epoch 34 with loss 0.034, I consider the trained model has satisfied some requirements and could deal with denoising but I got the 0dB audio which contains nothing but silence. I do not know whether it is related to the early stop but the very low loss makes it confusing.

@zfqy do you deal with 0 db problem?

Nope, but I discover a phenomenon that the denoised results are more likely to be silence with more epochs input into training process. Some input audio pieces are randomly set to be zero in the code with the rate 10% ( config.json : "noise_only_percent": 0.1), I haven't tried this yet but you could try and set it to zero. Good luck.

@zfqy I think you're True. I change noise_only_percent to zero, and then i get correct results as picture shows.

Congratulations bro. Thanks for your consideration and it helps me indeed.

Does anyone know the reason why noise augmentation shows this 0dB problem?
I tried 0.0 noise_only_augmentation setting several times.
For the lower epochs there is sound in *_denoisedNdB.wav,
but for the higher epoch (long, over 50 epoch) then I got the denoised0dB.wav (which contains silence only.)
