How to convert fbank features back to audio ?

[YuanGongND]

Hi there,

The goal of reconstruction loss here is just to force the model to learn a good audio representation. We didn't mean to make the model a strong reconstructor. But if you want to convert spectrogram back to waveforms, you will need a vocoder (not included in this repo).

Thanks for your warmly reply.
Any vocoder recommend? I want to inverse fbank features to audios.

Hi there,

I am not familiar with vocoder - you can check the github list: https://github.com/topics/vocoder. Note most of these are for TTS (speech) rather than general audio.
