如何从 Jupyter Notebook 下载音频？

Question

I have loaded an audio file in Python and I add some white noise to it. How do I download the new file with the white noise in it?

I have attached my code below. Please note that this is being done in Jupyter Notebook.

data = load_audio_file("chunk0_1.wav")
wn = np.random.randn(len(data))
data_wn = data + 0.01*wn
ipd.Audio(data_wn, rate=16000)

Answer 1

You can save the wav file using librosa, with the write_wav function.

Then in Jupyter you can browse to the file location and download it by checking the box and selecting download at the top.

Answer 2

If you are using Jupyter Lab, you should see something like this:

Left-click the three dots and you should get the opportunity for a local download. I am currently running GPUs in a specialized kubernetes container with multiple layers of indirection, but I access it on a windows laptop via Jupyter from anywhere, and I can download those individual files direct to my laptop.

I cannot at the moment verify this works on older Jupyter set-ups, but if you're not using Lab, strongly consider upgrading.
