Ez a funkció megkapja a gyors Fourier transzformációt, és létrehoz egy táblázatot az aktuális audiokeret összes frekvenciájáról, amely a spektrum mélyhangján kezdődik, majd halad a középtől a magas értékekig. Ez lehetővé teszi például a vizualizálást.
Szintaxis
table getSoundFFTData ( element sound, int iSamples [, int iBands = 0 ] )
OOP Syntax Help! I don't understand this!
- Method: sound:getFFTData(...)
Kötelező Argumentumok
- sound: egy hangelem, amelyet a playSound vagy a playSound3D segítségével hoztak létre. Valamint a stream is támogatott.
- iSamples: megengedett minták 256, 512, 1024, 2048, 4096, 8192 és 16384.
Tetszőleges Argumentumok
- iBands: post processing option allows you to split the samples into the desired amount of bands or bars so if you only need 5 bars this saves a lot of cpu power compared to trying to do it in Lua.
Vissza adott érték
Returns a table of iSamples/2 (or iBands if iBands is used) floats representing the current audio frame. Returns false if the sound is not playing yet or hasn't buffered in the case of streams.
