Downgrade "using all channels" warning to info - part 2 2020-01-25 04:17:53 +01:00

Explicitly use OSX
Previously this was inherited via PBD.

On MacOS/X,  this adds
  "-undefined dynamic_lookup -flat_namespace"
and various "-framework .." options to linkflags

Without this flag, .dylibs fail to link usually because
of missing `-lintl` (Undefined symbols: "_libintl_dgettext")

On other systems this is a NO-OP:
CFLAGS_OSX, CXXFLAGS_OSX and LINKFLAGS_OSX
are only set on the darwin platform.

Dummy: Engine-Pulse audio/midi generators
This produces synchronous events on Audio and MIDI ports.
One rvent per second, exactly at every second since engine-start.

MIDI: C-4 Note-on/off (1 sample long)
Audio: +1/-1 transition:
       +1 in sync with Note-on,
       -1 in sync with Note-off

NO-OP: fix some Wimplicit-fallthrough
gcc can recognize various regexps in comments. Since C++17 provides
[[fallthrough]], using /* fallthrough */ consistently seems
appropriate until we switch to C++17.

37df98d0af CoreAudio/MIDI: add locks for port-registration
CoreMIDI ports are dynamic. When dis/connecting a device CoreAudio's
AudioHardware-PropertyListener triggers a callback which can
add/remove ports.

This can not happen concurrently with processing, but it may happen
concurrently with a user creating tracks using Ardour's UI
and/or session-load/setup.

587a2dee55 backends: jack: display playback only devices
When starting ardour using the jack backend, playback only devices

case into account by adding them to the device list. Tested on Linux
with jack-alsa.

This issue is not always reproducible but when it does occur it happens

well be indefinite) and as it is not strictly necessary just remove it.

- 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 XML node for TempoSection named 'beats-per-minute'

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.

xxxAudioBackend::connected_to() is called O(N^2) when building the graph.
Mitigate this by using an O(log(N)) lookup.

This duplicates the storage (both set and map and both are kept in sync.
Changing this to a boost:bidirectional might be nice, before updating
other backends.

e9be313c11 Fix latency compensation for audio data in portaudio backend
For drivers that correctly report latency values(ASIO) this should result a
much closer alignment of audio in a loopback test. Measurement and
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.

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.
