Fantastic - looks great to me @MENGZHEGENG . Just some very minor changes requested in the submodules. Everything else looks good. I tested preprocessing out on my machine and it worked great. I didn't try training yet.

Could you also update the e2e dataset loader to use .wav and not .pt? https://github.com/roedoejet/EveryVoice/blob/03dca0e270e6cf173c12f8b71bd4139a9aa8db88/everyvoice/model/e2e/dataset.py#L102

It looks good Tim.

I di a few extra tests to compared training times using this and the latest version of EV. using 1000 entries of LJ .. Both took ~ 1h2minutes. So it looks like it does not impact the training performance.
