hello, i keep getting this error when using audiostretchy for a wav to wav speedup. any help would be appreciated. I am running it on windows

code:
from audiostretchy.stretch import stretch_audio
stretch_audio("input.wav", "output.wav", ratio=1.1)

error:

The code is running fine on a linux machine but the audio being produced has white noise after about 5 seconds, any suggestions on how to fix it?

I'm getting a similar error on Windows 11

It's the same for wav and mp3 files using the stretch_audio() or the AudioStretch() method

Will this bug be ever fixed? i have the exact same bug

Worked PERFECTLY first 3 minutes then this started to happen, rebooted PC, reinstalled the module, NOTHING HELPS wtf

Same OSError. Would love a fix.

Are you guys using a stereo input? It's working for me with mono but crashes with stereo.

Fixed it up by adding self.nchannels in the lines below.

audiostretchy/stretch.py:313

            self.samples = np.zeros(
                stretcher.output_capacity(self.nframes, ratio) * self.nchannels, dtype=np.int16
            )
            num_samples = stretcher.process_samples(
                self.in_samples, int( len(self.in_samples) / self.nchannels), self.samples, ratio
            )

There's a similar bit above this for silence_mode that may need changing too.

How do I compile _stretch.so, .dll, etc.?
