2020-04-07Atomically reset peak meters #7465Robin Gareus
2020-04-03Consistent processor labels "Meter"Robin Gareus
Track name is implicit, so instead of "meter-<name>", showing a translatable label "Meter" is sufficient and consistent with "Fader". Under the hood, for introspection, the processor name remains as is.

2019-06-09Consolidate meter-type state and APIRobin Gareus
In theory different UIs can show different meter-types, so it can make sense to maintain the type in different places. MeterType is a bit-set and PeakMeter implementation provides for this. However, this is not being used, and the current implementation was rather fragmented, cross-connected signals to keep types in sync, allowed inconsistent meter-types in GUI and backend. MeterType is now kept by meter itself, however it is still saved/restored as part of the Route state. N.B. This change breaks the API, various methods have been renamed for consistency.
2017-10-04Clean up State API:Robin Gareus
* Processor implement get_state(), classes derived from Processor implement protected ::state() -- as documented in processor.h * likewise for Route, Track: make ::state() a protected interface * removal of "full_state", use explicit "template_save" * use RAII/Unwind to skip saving automation-state

2016-06-25major internal plugin & processor API change:Robin Gareus
Pass current (latency compensated) cycle times to plugin. This fixes time-reporting to plugins and also fixes automation and when bouncing (the session->transport* is not valid) etc.
2015-09-28Fix Mackie control metering (fixes #6608).Len Ovens
2015-05-02professionalize peak-metersRobin Gareus
The peak meter needs to withstand various test-signals without visual jitter (in particular 1kHz sine) regardless of settings (period-size, sample-rate, custom fall-off). This needs to be done in sync (and not by a random non-rt ‘smoothing’ thread). On the downside this voids the ‘visual smoothing’ particularly with large buffersizes - but then again exactly this “always fall-off no matter what [the next real data will be]” is the problem. One the upside, there’s one less high-frequency (100Hz) thread (Yay!) PS. it probably never worked on windows, anyway. Only peak-meters are affected by his change. K-meters, IEC I/II and VU were never visually smoothed.
2015-04-29delegate signal emission to dedicated thread.Robin Gareus
This works around abysmal performance (~.15ms) of boost::function and boost::bind (in PBD::Signal). The overall load is probably higher but the realtime thread remains unaffected.

2013-08-02rework MIDI [processor|plugin] chainRobin Gareus
* forward midi-data around plugins that have no MIDI-out * allow to insert plugins with no MIDI-input at a point with one MIDI-channel This works because excess ports (both plugin and route) remain unconnected and use scratch-buffers. Tested with LV2, LXVST and LADSPA. (AU plugins with variable in/out retain the old behavior, no bypass) fixes http://tracker.ardour.org/view.php?id=5630
2013-07-25Don't allow to deactivate meter.Robin Gareus
before this change: 1) switch to 'custom' meter point, 2) deactivate meter processor. -> meters does not run regardless of meter-point -> meter can only be re-nabled in 'custom' mode

2013-03-27Squashed commit of the following:Paul Davis
commit fdbae82077db53add90df7448a06869dac89acc6 Author: Paul Davis <paul@linuxaudiosystems.com> Date: Wed Mar 27 21:45:28 2013 -0400 mammoth changes in basic signal flow, total redesign of MIDI channel filtering and more. commit 59343a8283698e02bc0f622313b29e98f449e4c8 Author: Paul Davis <paul@linuxaudiosystems.com> Date: Wed Mar 27 01:58:53 2013 -0400 initial working version after changes to MIDI channel filtering. may affect metering input too. testing not yet finished this commit merges many deep changes in ardour's internal architecture, combined with a total redesign of how MIDI channel filtering works. data in a track used to flow from JACK port buffers to diskstream's ringbuffers and was then copied from the ringbuffers into a BufferSet for use during Route::process_output_buffers(). The butler thread would handle the movement of data between the ringbuffers and disk. with this commit, data now flows from JACK port buffers into the BufferSet used for Route processing, and is copied from the BufferSet into the diskstream's ringbuffers (the butler thread continues to handle interactions with disk as usual). this change allowed a dramatic consolidation of code and simplification of most aspects of Track/Route::roll() and Track/Route::no_roll(). in particular, see Route::fill_buffers_with_input() which now concisely describes how we move data from JACK port buffers into the BufferSet for all Route types (including Tracks). this work was initially motivated by changing MIDI channel filtering so that we can process capture and playback independently. there is now a very clean pathway for this - see MidiTrack::roll() (NOTE: This needs implementing in the no-roll case too - a TODO item). the channel selector for MIDI tracks has been moved out of the track header and is now accessible via the context menu. more work is likely here, to make it (more) obvious to the user when filtering is going on.
2012-05-24Remove over 500 unnecessary includes (including 54 of session.h).David Robillard
It's slightly possible that this causes trivial build failures on different configurations, but otherwise shouldn't cause any problems (i.e. no actual changes other than include/naming/namespace stuff). I deliberately avoided removing libardour-config.h since this can mysteriously break things, though a few of those do seem to be unnecessary. This commit only targets includes of ardour/*.h. There is also a very large number of unnecessary includes of stuff in gtk2_ardour; tackling that should also give a big improvement in build time when things are modified. git-svn-id: svn://localhost/ardour2/branches/3.0@12420 d708f5d6-7413-0410-9779-e7cbd77b26cf

2009-05-07The great audio processing overhaul.David Robillard
The vast majority of Route signal processing is now simply in the list of processors. There are definitely regressions here, but there's also a lot of things fixed. It's far too much work to let diverge anymore regardless, so here it is. The basic model is: A route has a fixed set of input channels (matching its JACK input ports and diskstream). The first processor takes this as input. The next processor is configured using the first processor's output as input, and is allowed to choose whatever output it wants given that input... and so on, and so on. Finally, the last processor's requested output is used to set up the panner and create whatever Jack ports are needed to output the data. All 'special' internal processors (meter, fader, amp, insert, send) are currently transparent: they read any input, and return the same set of channels back (unmodified, except for amp). User visible changes: * LV2 Instrument support (tracks with both MIDI and audio channels) * MIDI in/out plugin support * Generic plugin replication (for MIDI plugins, MIDI/audio plugins) * Movable meter point Known Bugs: * Things seem to get weird on loaded sessions * Output delivery is sketchy * 2.0 session loading was probably already broken... but it's definitely broken now :) Please test this and file bugs if you have any time... git-svn-id: svn://localhost/ardour2/branches/3.0@5055 d708f5d6-7413-0410-9779-e7cbd77b26cf

2009-02-25*** NEW CODING POLICY ***David Robillard
All #include statements that include a header that is a part of a library bundled with ardour MUST use quotes, not angle brackets. Do this: #include "ardour/types.h" NOT this: #include <ardour/types.h> Rationale: This is best practice in general, to ensure we include the local version and not the system version. That quotes mean "local" (in some sense) and angle brackets mean "system" (in some sense) is a ubiquitous convention and IIRC right in the C spec somewhere. More pragmatically, this is required by (my) waf (stuff) for dependencies to work correctly. That is: !!! FAILURE TO DO THIS CAN RESULT IN BROKEN BUILDS !!! Failure to comply is punishable by death by torture. :) P.S. It's not that dramatic in all cases, but this (in combination with some GCC flags specific to the include type) is the best way I have found to be absolutely 100% positive the local ones are being used (and we definitely want to be absolutely 100% positive on that one). git-svn-id: svn://localhost/ardour2/branches/3.0@4655 d708f5d6-7413-0410-9779-e7cbd77b26cf
