Hola, no sé si será de utilidad, pero hace unos años escribí una serie de objetos para max que realizaban síntesis por onditas (wavelets) por medio de una implementacion del algoritmo de Daubechies. No trabajan en tiempo real. Solo llenan tablas de onda. Como el código está disponible en los archivos zip, quizá pueda ser reutilizado para escribir objetos en PD o SC que trabajen en tiempo real. Son jmb.dauby, jmb.daubya y jmb.daubyb. Están en mi página web en el link a cosas de Max :
