float	clip
	Clip indicator (set to 1 when |value| >= 1, fading otherwise).

	Falloff of clip indicator (b1 coefficient of a 1-pole filter); set to 1 if no falloff is required (manual reset of clip indicator).
int	count_over
	Amount of samples > 1.f; Clipping occurs if 3 samples are over 0dB.

inline

Member Function Documentation

copy_falloff()

void dsp::vumeter::copy_falloff ( const vumeter & src )

inline

Copy falloff from another object.

fall()

void dsp::vumeter::fall ( unsigned int len )

inline

process()

void dsp::vumeter::process ( const float value )

inline

reset()

void dsp::vumeter::reset ( )

inline

run_sample_loop()

void dsp::vumeter::run_sample_loop ( const float * src, unsigned int len )

inline

set_falloff()

void dsp::vumeter::set_falloff ( double time_20dB, double sample_rate )

inline

inline

update()

void dsp::vumeter::update ( const float * src, unsigned int len )

inline

Update peak meter based on input signal.

update_stereo()

void dsp::vumeter::update_stereo ( const float * src1, const float * src2, unsigned int len )

inline

Update peak meter based on louder of two input signals.

update_zeros()

void dsp::vumeter::update_zeros ( unsigned int len )

inline

Update clip meter as if update was called with all-zero input signal.

Member Data Documentation

clip

float dsp::vumeter::clip

Clip indicator (set to 1 when |value| >= 1, fading otherwise).

clip_falloff

float dsp::vumeter::clip_falloff

Falloff of clip indicator (b1 coefficient of a 1-pole filter); set to 1 if no falloff is required (manual reset of clip indicator).

count_over
