Essa função obtém os parâmetros de um efeito sonoro.

Sintaxe

table getSoundEffectParameters ( element audio, string efeito )

Sintaxe POO(OOP) Não entendeu o que significa isso?

Método: audio:getEffectParameters(...)

Argumentos necessários

  • audio: o elemento de áudio.
  • efeito: o nome do efeito sonoro ao qual os parâmetros você deseja obter.
  • gargle
  • compressor
  • echo
  • i3dl2reverb
  • distortion
  • chorus
  • parameq
  • reverb
  • flanger

Retorno

Retorna uma tabela com os nomes dos parâmetros nas chaves e seus valores. Se o nome do efeito especificado no segundo argumento não existir, um erro será exibido.
