Never completes.

[cocode]

Hi -

Even when using the "Simplest usage" code, it never returns, until it throws a signal 10+ minutes later, on a twenty-second wav file.

Does this require linux? (I'm on a mac), or some particular version of python? (I'm using 3.10).

Currently, it does not work for me, at all.

Hmm. I tried several files wav files, and found one that did complete. The others are valid, and play on multiple players. What are the requirements for a .wav file to work with noisereduce?

Hello, I’m not by a computer until October so I can’t help just now, but is it possible you could upload a wav file that doesn’t work? Thanks!

Try this

`
from scipy.io import wavfile
import noisereduce as nr
import numpy as np

rate, data = wavfile.read("file.wav")
nframes, nchannels = data.shape
reduced_data = nr.reduce_noise(y=data.reshape(nchannels, nframes), sr=rate)
wavfile.write("file.wav", rate, reduced_data.reshape(nframes, nchannels))
`

Btw, I ran into this problem with WAV files with more than 1 channels (8 in my case)

Ryan: your solution works for me too.

The channels and samples are just transposed in these cases, we could catch this by raising an error if there are more than say 1000 channels.
