Very simple question

Thank you for the wonderful software!

It used to work fine, until I attempted using a very basic code, and for whatever reason it does not work. Why?

import soundfile as sf
sample_rate = 48000
wavdata = []

for i in range(10):
    wavdata.append(0)

for x in range(40):
    wavdata.append(1)

for y in range(10):
    wavdata.append(0)

sf.write('blip.wav', wavdata, sample_rate)  

Thank you so much!!

what's the error message?

Thank you for the reply! When viewed in Audacity, the wav is simply all zeros.

@zeke800 You might want to explicitly specify the data format subtype i.e., in your case maybe 'FLOAT'?

EDIT: From how I quickly grasp the implementation, *.wav files would use 'PCM_16' by default, which would require values to be scaled to 16bit integer for full-scale (to show up as 1 in the floating point representation in Audacity).

Try writing float data
