RTBUF Type Reference

C types

double

64 bit Double-precision floating-point format .

Signal types

See rtbuf_signal.h for details.

Signal sample

A signal sample is defined to be a 64 bit double float.

typedef double t_rtbuf_signal_sample;
#define RTBUF_SIGNAL_SAMPLE_SIZE sizeof(t_rtbuf_signal_sample)
#define RTBUF_SIGNAL_SAMPLE_TYPE "double"

Signal

A signal is an array of RTBUF_SIGNAL_SAMPLES samples.

#define RTBUF_SIGNAL_SAMPLES     1024
typedef t_rtbuf_signal_sample t_rtbuf_signal[RTBUF_SIGNAL_SAMPLES];
#define RTBUF_SIGNAL_SIZE sizeof(t_rtbuf_signal)
#define RTBUF_SIGNAL_TYPE RTBUF_SIGNAL_SAMPLE_TYPE "[1024]"

Signal function

A signal function is a typed accessor to sample data.

A signal function can access sample data per frame from either a single sample or from a signal (an array of RTBUF_SIGNAL_SAMPLES samples).

typedef t_rtbuf_signal_sample
f_rtbuf_signal (const t_rtbuf_signal_sample *signal,
                unsigned int sample);

typedef struct rtbuf_signal_fun {
  f_rtbuf_signal *sample_fun;
  const t_rtbuf_signal_sample *signal;
} s_rtbuf_signal_fun;

void rtbuf_signal_zero (t_rtbuf_signal_sample *signal);
t_rtbuf_signal_sample

void rtbuf_signal_fun (s_rtbuf *rtb,
                       unsigned int in,
                       s_rtbuf_signal_fun *data);

f_rtbuf_signal rtbuf_signal_sample_from_sample;
f_rtbuf_signal rtbuf_signal_sample_from_signal;
