I am looking for a Software from which I can Extract the Sound Waves to be used in a Graphic Software. It is basically for gifting to someone. Can someone guide me in right direction? A command line tool should also be just fine.

This question came from our site for sound engineers, producers, editors, and enthusiasts.

  • Do you want to export the whole sound wave to an image? Even for one second of sound that makes a very big image. Or are you OK with only 1000 pixels? – Nicolas Raoul Nov 5 at 9:39
  • I came across this recently so haven't used it yet but the html 5 web audio api might be able to help css-tricks.com/introduction-web-audio-api – karen Nov 5 at 10:40

The FFmpeg showwavespic filter can produce an image of the waveform of an audio input and has a few parameters to customize the output.

Here's an example invocation (from the above link) :

ffmpeg -i audio.flac -lavfi showwavespic=split_channels=1:s=1024x800 waveform.png

Example output: enter image description here
