Re: sndfile-waveform PNG generator ?

[Vytautas Jancauskas <unaudio@xxxxxxxxx>]

import matplotlib.pyplot as plt

import scipy.io.wavfile as wav

import sys

if __name__ == '__main__':

    data = "">

    plt.plot(data[1])

    plt.show()

    

The python code to show wave data from a command line file name is above. You can modify it easily to output a .png image. Read matplotlib documentation.

It's fairly trivial to write one your own with python using scipy. Should be in the ballpark of 20 lines or so.

Hi *,

Is there a command-line tool akin to `sndfile-spectrogram` that
generates an image (preferably PNG) of an audio wave-form?

I found endless GUI apps, but command-line tools are scarce.

TIA
robin
