Typedefs
typedef struct gavl_peak_detector_s	gavl_peak_detector_t
	Opaque structure for peak detector.
typedef void(*	gavl_update_peak_callback) (void *priv, int samples, double min, double max, double abs)
	Callback for getting the peaks across all channels.
typedef void(*	gavl_update_peaks_callback) (void *priv, int samples, const double *min, const double *max, const double *abs)
	Callback for getting the peaks for all channels separately.
