lovewav

Use this lightweight library with LÖVE framework to generate WAV file data from love.SoundData.

Usage

Below is an example with Lua:

-- main.lua

-- this file will generate a 1 second sine wave and save it to save folder

local lovewav = require("lovewav")

local sample_rate = 44100
local freq = 440

local sound_data = love.sound.newSoundData(sample_rate, sample_rate, 16, 1)

for i = 0, sample_rate - 1 do
    local sample = math.sin(math.pi * 2 * freq * i / sample_rate)
    sound_data:setSample(i, sample)
end

local wav_data = lovewav(sound_data)

love.filesystem.write("output.wav", wav_data)

You can also use the libary with YueScript:

-- main.yue (to be transpiled to main.lua)

-- this file will generate a 1 second sine wave and save it to save folder

import "lovewav"

sample_rate = 44100
freq = 440

sound_data = love.sound.newSoundData sample_rate, sample_rate, 16, 1

for i = 0, sample_rate - 1
    sample = math.sin math.pi * 2 * freq * i / sample_rate
    sound_data\setSample i, sample

wav_data = lovewav sound_data

love.filesystem.write "output.wav", wav_data
