love.sound.newSoundData

Creates new SoundData from a filepath, File, or Decoder. It's also possible to create SoundData with a custom sample rate, channel and bit depth.

The sound data will be decoded to the memory in a raw format. It is recommended to create only short sounds like effects, as a 3 minute song uses 30 MB of memory this way.

-- Beware: if doom.mp3 is a huge file, it will take 
-- ages to decode.
mp3 = love.sound.newSoundData("doom.mp3")

Beep function

local rate = 44100 -- samples per second
local length = 1/32 -- 0.03125 seconds
local tone = 440 -- Hz
local p = math.floor(rate/tone) -- 100 (wave length in samples)
local soundData = love.sound.newSoundData(length*rate, rate, 16, 1)
for i=0, length*rate-1 do 
	soundData:setSample(i, i%p<p/2 and 1 or -1) -- the half of the wave is 1, another half is -1
end
local source = love.audio.newSource(soundData)
local function beep() source:play() end
