Make your own jumps!

Djump is a tool that lets you craft your own chiptune-style jumping sound effects!

Three six-note wave channels with per-channel wave-shapes are supported. You can choose any natural note within 8 octaves, specify the length and volume of each note, and even slide one note's frequency and volume to the next one!

Saving, loading, and exporting audio are all supported as well. Click on the heart icon to load some presets and see what's possible!

Controls

All buttons are used by left clicking, as you'd expect.

Left clicking a number input increases the value by one, right clicking will decrease it by one. The mouse scroll-wheel can also be used to quickly change values when hovering over an input.

To play your sound (and make the little guy on the right jump) you can click on the logo on the bottom right, or press your spacebar.

A Note About Exporting

Currently, the tool can only output audio files in .webm format. I've not yet figured out a way around this, which means you'll most likely have to convert it to another format before you use it.
