Modulate brown noise in python

[pyxel]

Indeed I looked at the documentation, but I did not find what I wanted.

I tried something else:

newWaveFile.writeframes(struct.pack('h'*framerate*duration, int(maxVolume*0.7*acoustics.generator.brown(framerate*duration))))

But python does not like it:

Error:
TypeError: only size-1 arrays can be converted to Python scalars

Any idea?
