sfxr.lua

A port of the sfxr sound effect synthesizer to pure Lua, designed to be used together with the awesome LÖVE game framework.

Demo

To run the demo application you first need to download LoveFrames as a submodule:

git submodule update --init
love demo

Note: Due to LoveFrames only supporting LÖVE 0.9.x, this dependency is inherited by the demo. A move to a new GUI framework is pending.

Example usage

The following code examples demonstrate how to play a randomly generated sound:

With LÖVE:

local sfxr = require("sfxr")

function love.load()
    local sound = sfxr.newSound()
    sound:randomize()
    local sounddata = sound:generateSoundData()
    local source = love.audio.newSource(sounddata)
    source:play()
end

With lao:

require("ao")
local sfxr = require("sfxr")

local driverId = ao.defaultDriverId()
local device = ao.openLive(driverId, {bits = 16, rate = 44100, channels = 1})

local sound = sfxr.newSound()
sound:randomize()

local buffer = sound:generateString()
device:play(buffer, #buffer)
