Constructor & Destructor Documentation

Delay() [1/2]

sbl::widgets::proc::Delay::Delay ( float *  buf_l, float *  buf_r, uint32_t  max_samples  )

inline

Construct with caller-provided float buffers.

Note

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

Parameters

buf_l	Left delay buffer (must outlive the Delay)
buf_r	Right delay buffer (must outlive the Delay)
max_samples	Maximum delay in samples (buffer size)

Definition at line 43 of file delay.hpp.

sbl::widgets::proc::Delay::Delay ( )

default

Default constructor (must call init() before use)
