🤖 🤞

./audiowaveform -i ../path/to/audio.mp3 -o ../path/to/audio.png --end 211 -w 8000 -h 200 --no-axis-labels --background-color 00000000 --waveform-color EF5350FF --border-color 00000000

Output

❌ ✋

TODO:

• Set the customizations as argument instead of hardcoding them
• Fix: not whole waveform is generated (the incrementation is wrong)

Thanks for contributing! If we were to add this feature, we'd need a few options:

• waveform-style: normal / bars
• bar-width
• bar-gap
• bar-style: square / rounded

I know this is from a long time ago but would be a nice feature to add, a lot of websites and apps use this style now.

Hi @chrisn, I'd be keen to take over this PR and make it happen.
Appart from the said missing options and perhaps the "Fix: not whole waveform is generated (the incrementation is wrong)"

Is there anything else I should worry about?

Thanks
