Member Function Documentation
◆ set_filter()
| void apf::conv::Output::set_filter | ( | const Filter & | filter | ) |
Set a new filter.
The first filter partition is updated immediately, the later partitions are updated with rotate_queues().
- Parameters
-
filter Container with filter partitions. If too few partitions are given, the rest is set to zero, if too many are given, the rest is ignored.
Definition at line 659 of file convolver.h.
◆ queues_empty()
| bool apf::conv::Output::queues_empty | ( | ) | const |
Check if there are still valid partitions in the queues.
If this function returns false, rotate_queues() should be called.
- Note
- This is important for crossfades: even if set_filter() wasn't used, older partitions may still change! If the queues are empty, no crossfade is necessary (except
weightwas changed in convolve()).
Definition at line 683 of file convolver.h.
◆ rotate_queues()
| void apf::conv::Output::rotate_queues | ( | ) |
Update filter queues.
If queues_empty() returns true, calling this function is unnecessary.
- Note
- This can lead to artifacts, so a crossfade is recommended.
