Spectrograms Not Equal When Running Tests

[jvel07]

Hi, thanks for the repo, seems to be promising. We have run some tests with your test file and got:

AssertionError: 
Not equal to tolerance rtol=1e-07, atol=0.0001
(shapes (513, 30), (513, 1, 14977) mismatch)
 x: array([[4.878030e-09, 4.919218e-07, 3.511721e-04, ..., 1.196331e-01,

       [1.071588e-08, 1.510490e-06, 3.254034e-04, ..., 9.578773e-02,...

         1.956094e-02, 1.939876e-02]],

This is just for the spectrograms --not currently testing mel_specs. We are testing test_melpec_vs_torchaudio().
Any ideas on the possible reasons?

UPDATE: similar outcome with test_melpec_vs_librosa()

Apologies for the huge delay. I just re-ran the tests and they are all passing on my macOS arm64 machine:

To reproduce this, I basically created a micromamba environment called convspec as follows (conda should work too):

micromamba env create -n convspec python=3.9
micromamba activate convspec
pip install -e .

And then ran the tests as showed above.

What system are you trying this on?
