Syntax

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

Required Arguments

  • sound: A sound element that is created using playSound or playSound3D. Streams are also supported
  • iSamples: Allowed samples are 128, 256, 512, 1024, 2048, 4096, 8192 and 16384

Optional Arguments

  • 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

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.
