Constructor & Destructor Documentation

DelayLine()

sbl::dsp::DelayLine::DelayLine ( float *  buffer, uint32_t  max_delay  )

inline

Construct with caller-provided buffer.

Note

All public methods are ISR-safe — bounded computation, no I/O.

Parameters

buffer	Float buffer (must outlive the DelayLine)
max_delay	Maximum delay in samples (buffer size)

Definition at line 27 of file delay_line.hpp.

Member Function Documentation

clear()

void sbl::dsp::DelayLine::clear ( )

inline

Zero all samples in the buffer.

Definition at line 69 of file delay_line.hpp.

max_delay()

uint32_t sbl::dsp::DelayLine::max_delay ( ) const

inline

Maximum delay in samples.

Definition at line 77 of file delay_line.hpp.

read()

float sbl::dsp::DelayLine::read ( uint32_t  delay ) const

inline

Read a sample at integer delay.

Parameters

delay

Delay in samples (0 = most recent write)

Returns

Delayed sample

Here is the caller graph for this function:

read_fractional()

float sbl::dsp::DelayLine::read_fractional ( float  delay ) const

inline

Read with fractional delay (float)

Linear interpolation between adjacent samples.

Parameters

delay

Fractional delay in samples (e.g. 10.5f)

Returns

Linearly interpolated sample
