unsigned int | sample_rate () const |
Read the sample rate as specified in the wav file header. | |
int | bits_per_sample () const |
Return the number of bits per sample as specified in the wav file header. Only 8 or 16 bit are supported here. | |
int | channels () const |
Return the number of channels in the wav file as specified in the wav file header. This is also the max number of outputs you can have. | |
