Blip

Blip is a library to procedurally generate and play sound effects for games. The library is based on the Sfxr project by Dr.Petter.

Installation

You can use Blip in your own project by adding this project as a Defold library dependency. Open your game.project file and in the dependencies field under project add:

https://github.com/britzl/blip/archive/master.zip

Or point to the ZIP file of a specific release.

Usage

You generate a sound by calling one of the predefined sound effect groups:

local seed = 1234
local wav = blip.explosion(seed)

This will generate a sound effect as a WAV sample using the specified seed. The seed is a number that is used to generate a specific version of the sound effect. Passing in a certain seed will always result in the same sound. Use the example app to find seeds that you like and use them in your own project.

Once you have a sound effect that you like you set it on an existing sound component and play the sound:

-- set the sound data on the sound component #sound
local resource_path = go.get("#sound", "sound")
resource.set_sound(resource_path, wav)

-- play the sound
sound.play("#sound")

Try it!

Try the HTML5 version of the example app.
