DecodeWav

Decodifica un archivo PCM WAV de 16 bits en un tensor flotante.
Los valores de 16 bits con signo de -32768 a 32767 se escalarán de -1,0 a 1,0 en flotante.
Cuando se configuran los canales deseados, si la entrada contiene menos canales que estos, entonces el último canal se duplicará para dar el número solicitado; de lo contrario, si la entrada tiene más canales de los solicitados, los canales adicionales se ignorarán.
Si se establece wanted_samples, el audio se recortará o se rellenará con ceros hasta la longitud solicitada.
La primera salida contiene un Tensor con el contenido de las muestras de audio. La dimensión más baja será la cantidad de canales y la segunda será la cantidad de muestras. Por ejemplo, un archivo WAV estéreo de diez muestras debería dar una forma de salida de [10, 2].
