Clarification for the first question - because here spectrogram is being normalized by the argument I think the answer on my question will be yes.
from encodec.
Clarification for the second question - in the formula number (5) in the SoundStream paper the log is being taken of the mel-spec when computing L2 part of the multi-scale spectral reconstruction loss, so the question remains, did you remove it on purpose?
from encodec.
And one more question about the multi-scale spectral reconstruction loss, when constructing MelSpectrogram
with 64 n_mels
and window_size
< 512 I get the following warning (4 of them)
/opt/conda/lib/python3.10/site-packages/torchaudio/functional/functional.py:539: UserWarning: At least one mel filterbank has all zero values. The value for n_mels (64) may be set too high. Or, the value for n_freqs (65) may be set too low.
Is it an expected behavior and I should leave this loss as it is?
from encodec.
