At 44/48khz, the main delay line comes out to 20k to 22k samples, which gets
rounded up to 32k as the next power of two. This leaves plenty of room for the
full 1k BUFFERSIZE without having to increase the delay line beyond what it
already is.
It still requires a proper custom decoder configuration for speakers, so that
proper distances can be specified. Ambisonic output still relies on the
nfc-ref-delay option, and HRTF uses the dataset's distance.
Remove the cmake function:
INCLUDE_DIRECTORIES(..)
Replace it by:
TARGET_INCLUDE_DIRECTORIES(...)
It gives us the opportunity to define whether or not OpenAL dependencies
should be exported or not (using PUBLIC or PRIVATE keywoard).
[user visible changes]
The OpenAL PUBLIC headers are exported. When a target depends on OpenAL,
it will have access to its public headers.
Some small refactor along the way.
Specifically, the A2B and output mixing, as well as applying the band-pass with
B2A mixing (the latter of which hiding a bug that was overwriting the early
buffer storage).
Particularly, handle "holes" in the record stream and premature end-of-buffer.
Also don't bail out when capturing while disconnected (the extension says it
should provide anything it previously reported available, going to silence for
anything no longer readable).
Unfortuantely, the relevant KDE bug still seems to exist (streams are forced to
KDE's default device after opening, even when they're created with a specific
device at user request). I do not know why KDE thinks this is in any way good
behavior (the user doesn't get their desired device, nor does the stream get
the appropriate format for the device its ultimately put on), but making
streams non-movable as a workaround has been a thorn in the side of non-KDE
users for too long. C'mon KDE, it's been nearly (if not more than) 7 years now.
