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
2013-07-25reset meters only when *really* necessaryRobin Gareus
..and continue to calculate fall-off in audio-cycle (rather than UI thread) TODO: check if this works properly when switching between audio/midi meter modes on a midi-track. One of the motivations to always reset meters when the meter-point changes was to resolve peak-hold & fall-off issues when a midi-meter replaces an audio-meter and vice versa.

2013-07-10use accurate log10 for meter (fast_log2 is unsuitable inaccurate)Robin Gareus
fast_coefficient_to_dB() returns a lower bound value, unsuitable to catch audio peaks. The difference to 20*log10 is as large as 0.4 dB! The effective speedup of fast_log10 compared to log10f is marginal (sweep of all 24bit values) i686 (1.6GHz Intel core): 2.36 [times faster] x86_64 (core2 2.4GHz): 1.63 x86_64 (I3 2.80GHz): 2.03 the execution time of one log10f() averaged over a sweep of all 24 bit values i686 (1.6GHz Intel core): 0.131 usec x86_64 (core2 2.4GHz): 0.033 usec x86_64 (I3 2.80GHz): 0.044 usec PeakMeter::run() is called from dedicated non-rt, no harm done.

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
