◆ apply_gain_to_buffer()

static void AudioGrapher::Routines::apply_gain_to_buffer ( float *  data,
uint_type  samples,
float  gain 
)
inlinestatic

Applies constant gain to buffer
RT safe

Parameters
datadata to which the gain is applied
sampleslength of data
gaingain that is applied

Definition at line 43 of file routines.h.

float  current_peak 
)
inlinestatic

Computes peak in float buffer
RT safe

Parameters
databuffer from which the peak is computed
sampleslength of the portion of buffer that is checked
current_peakcurrent peak of buffer, if calculated in several passes
Returns
maximum of values in [data, data + samples) and current_peak
