Support playing of mono/stereo np.array waveform in cell output

[p-i-]

I perform work as an audio/DSP engineer.

I generate waveforms in Notebook cells, and use display( Audio( waveform, rate=SAMPLERATE ) ) where waveform is a 1D or 2D numpy.array

This works in Jupyter Notebook (browser-based) but not in VSCode's .ipynb editor.

Numerous issues have been filed, e.g. microsoft/vscode-jupyter#1012 (116 upvotes) and #118275 (176 upvotes).

This is a gaping hole in an exquisitely engineered product.

The conversation cites difficulties with ffmpeg, possibly licensing issues. I can find no clear exposition of what the blocker is.

Could we please have, as a stopgap, a basic functionality for playing a mono/stereo numpy.array from a cell output?

This will yield massive bang-for-buck -- engineers will be able to use their initiative to convert audio into raw numpy arrays, and... achievement unlocked.

Please could your team consider prioritizing this?

This makes a lot of sense. I am happy to do the conversion with code and accept the license terms for ffmpeg on my own. All I need is for VSCode to play raw signals that's in a numpy array.
