NO-OP: Consolidate PortConnect code into shared parent class 2020-09-05 23:05:57 +02:00
92f54b3e98
Add API to query if systemic latency can be measured 2020-06-30 03:34:26 +02:00
b9cb306e8b use shared_ptr to manage backend port lifetimes (Pulse,ALSA,Dummy,JACK)
JACK is not yet finished.

Changes also include minor reformatting and a spelling correction (latecies to latencies)

076e9fddd4
Remove ambiguous API implementation
* PortEngine::available() implementation
* AudioEngine::connected() wrapper

Eventually we may re-introduce PortEngine::available along
with a libardour internal port-engine.

e047b01aa2 add new API for retrieving port flags from backend 2018-10-17 14:11:37 -04:00
ab3889fff8 Propagate Latency to backend/system ports
Set accumulated capture-latency for physical-outputs
and accumulated playback-latency for physical-inputs
after Ardour is done setting all non-physical port latencies.

This will be needed for latency-compensation of the complete graph.

30b087ab3d globally change all use of "frame" to refer to audio into "sample".
Generated by tools/f2s. Some hand-editing will be required in a few places to fix up comments related to timecode
and video in order to keep the legible

a65b1ddedc Add a DSPLoadCalculator class to the PortAudioBackend for DSP load calculation
The class uses the same algorithm as in the coreaudio and alsa backends and
should probably go into libardour at some point
