7e2c002ef6 Propagate Latency to backend/system ports (Dummy backend)

e39a8b90d9 amend ab3889ff: portaudio backend uses a vector for connections 2017-09-23 01:06:10 +02:00
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.

467c801ce8 Abstract definition of rt-scheduler policy
pthread-w32 does not support pthread_setschedparam() with

and sets the priority regadless.

587a2dee55 backends: jack: display playback only devices
When starting ardour using the jack backend, playback only devices
currently do not get displayed. Mixing and Mastering only workspaces
with e.g. a single USB Dac should be a common use case. Take this use
case into account by adding them to the device list. Tested on Linux
with jack-alsa.

d10913e2de Fix intermittent hang when stopping PortaudioBackend
This issue is not always reproducible but when it does occur it happens
somewhat consistently on both 32bit and 64bit builds(Tested on Windows 7).

The midiOutReset call does not return (or it takes so long that it might as
well be indefinite) and as it is not strictly necessary just remove it.

33e95a1577 rename Tempo _beats_per_minute to _note_types_per_minute, provide pulse helpers.
- adds quarter_notes_per_minute(), note_divisions_per_minute (double)
	  pulses_per_minute() and frames_per_quarter_note()

	- this should be a no-op except for the use of tempo by
	  the vst callback which definitely uses quarter notes per minute.

	- the XML node for TempoSection named 'beats-per-minute'
	  has been renamed.

34c9ac9dd7 Tempo ramps - rename bbt_time() -> bbt_at_frame(), frame_time() -> frame_at_bbt() 2016-05-27 23:38:17 +10:00
nick_m
7fc3b0c34c Initial stab at tempo ramps.
Replaces the list of points in TempoMap with TempoSection functions, which
compute tempo-at or tick-at time relative to tempo section start.
TempoMap consults them additively to determine things like bbt_time(),
frame_time() get_grid() etc.
This has a marked effect on scrolling speed along with the code simplification
in the places it has been attempted.

Several things are broken here.
Currently every ramp except the last one is an exponential ramp. this may
be simple to fix :).
Mouse-over midi grid doesn't match mouse click grid. should also be simple.

Many things seem to work, but their accuracy should be in question until
each area has been addressed.

For drivers that correctly report latency values(ASIO) this should result a

adjustment may still be needed, especially for non-ASIO drivers.

Testing with the RME HDSP Multiface and Yamaha AG06 using ASIO drivers results
in maximum offset of a couple of samples.

07b2518979 Fix windows build when using pthreads-win32 library 2015-11-19 20:54:38 +10:00
ac301b998a Use a range of values for ASIO buffer sizes if provided by driver
This has been tested on four devices:

- A RME HDSP Multiface
- A Yamaha AG06
- A Focusrite 2i2
- A built-in soundcard running ASIO4ALL

The HDSP and the AG06 only return one buffer size when queried so the preferred
size is used as before.

The Focusrite returns a min corresponding to the position of the slider in the
control dialog and the max is 1024. The granularity is 1 so this means that the
number of values needs to be reduced for the current UI design with a combo
box so the granularity is increased until there are around 8-9 buffer sizes to
choose from evenly spaced between min and max(but we could easily change this
if the UI changes etc).

The ASIO4ALL driver returns a min of 64 and a max of 2048 and a granularity of
8. So where the minimum buffer size and granularity is a power of 2 use only
buffer sizes that are power of 2.

If the driver returns different values for min and max it is not currently
possible to indicate which is the driver preferred value. A checkbox or other
UI element could be added to the AudioSetup dialog to only use the preferred
value but that is more work and perhaps not necessary.

a fallback using jack_port_set_name().

midiInReset triggers the sysex callback to tell the application that it has

so just return during shutdown.

dcf327f86a Return meaningful error codes when ALSA backend fails to start
Unfortunately it seems that in zita-alsa-pcmi doesn't set state() correctly in
some cases. Setting an invalid SR doesn't display the correct error message,
first guess would be that set_hwpar is failing and state() is not
representative of the actual error.

2015-10-01 09:10:19 +10:00
f178152114 Use portaudio error codes in the PortaudioIO class.
Having error codes defined in PortaudioIO means it is not dependent on the
ErrorCodes in AudioBackend but it doesn't really make sense to have another
set, so just use the PA ones until they become insufficient.
