<arg name="samplerate" type="number">The sample rate of the sound. Must be 11025, 22050 or 44100.</arg>
<arg name="length" type="number">The length in seconds of the sound to generate.</arg>
<arg name="callback" type="function">A function which will be called to generate every sample on the sound. This function gets the current sample number passed as the first argument. The return value must be between -1.0 and 1.0. Other values will wrap back to the -1 to 1 range and basically clip. There are 65535 possible quantifiable values between -1 and 1.</arg>

<description>Plays a 2000 Hz sine wave at maximum volume</description>
<code>
local frequency = 2000 -- Hz
local samplerate = 44100
local function data(t)
return math.sin( t * math.pi * 2 / samplerate * frequency )
end
test_sound_id = test_sound_id and test_sound_id + 1 or 10
sound.Generate ("testgen" .. test_sound_id, samplerate, 2, data)
surface.PlaySound("testgen" .. test_sound_id)
