Interfaces

wdelaycf wdelaycf_create(unsigned int _delay)∞

Create delay buffer object with a particular number of samples of delay

• _delay : number of samples of delay in the wdelay object

wdelaycf wdelaycf_copy(wdelaycf _q)∞

Copy object including all internal objects and state

wdelaycf wdelaycf_recreate(wdelaycf _q, unsigned int _delay)∞

Re-create delay buffer object, adjusting the delay size, preserving the internal state of the object

• _q : old delay buffer object
• _delay : delay for new object

int wdelaycf_destroy(wdelaycf _q)∞

Destroy delay buffer object, freeing internal memory

int wdelaycf_print(wdelaycf _q)∞

Print delay buffer object's state to stdout

int wdelaycf_reset(wdelaycf _q)∞

Clear/reset state of object

int wdelaycf_read(wdelaycf _q, float complex * _v)∞

Read delayed sample at the head of the buffer and store it to the output pointer

• _q : delay buffer object
• _v : value of delayed element

int wdelaycf_push(wdelaycf _q, float complex _v)∞

Push new sample into delay buffer object

• _q : delay buffer object
• _v : new value to be added to buffer
