AR/getSoundFFTData

This function gets the fast fourier transform data for an audio stream which is a table of floats representing the current audio frame. This allows things like visualisations.

a fast fourier transform generates a table of all the frequencies of the current audio frame which starts at the bass end of the spectrum to mids to highs in that order

Should you have any problems there is an example resource located on the resource svn here: Visualiser

just type "startmusic mystreamurl" in your console and it will play on the cinema billboard near A51 If the element is a player, this function will use the players voice.

Syntax

table getSoundFFTData ( element sound, int iSamples [, int iBands = 0 ] )

Required Arguments

sound:عنصر الصوت يتم انشاؤه باستخدام playSound او playSound3D.
iSamples: العينات المسموح بها هي 128 و 256 و 512 و 1024 و 2048 و 4096 و 8192 و 16384

Optional Arguments

iBands: يسمح لك خيار ما بعد المعالجة بتقسيم العينات إلى العدد المطلوب من الأشرطة أو الأشرطة ، لذلك إذا كنت تحتاج إلى 5 أشرطة فقط ، فهذا يوفر الكثير من طاقة المعالج مقارنة بمحاولة القيام بذلك في Lua

Returns

Returns a table of floats representing the current audio frame. Returns false if the sound is not playing yet or hasn't buffered in the case of streams.

Example

addCommandHandler("playsound",
function () 
    local sound  = playSound("wasted.mp3")
    local data = getSoundWaveData(sound, 512) -- returns table
    for i, v in pairs(data) do
        outputChatBox(v) -- outputs the float representing the current audio frame
    end
end
)
