fixes#6277
This indicates a deeper problem though. Even removing a punch-range never
clears out the events. and ession::process_with_events() does not use
process_without_events() until re-start.
This still leaves cache_aligned_malloc() in
libs/pbd/malign.cc pending _aligned_free (windows crashes when using
free() on memory allocated with _aligned_malloc()).
So far however there seems to be no issue with default malloc
for audio+midi buffers on win32…
1) Disambiguate 1.0 to GAIN_COEFF_UNITY, and 0.0 to GAIN_COEFF_ZERO
2) Add GAIN_COEFF_SMALL which replaces SMALL_SIGNAL (-140dB)
3) GAIN_COEFF_SMALL can used to avoid interpolating towards -inf on a db scale
4) GAIN_COEFF_SMALL is used to detect very small (denormal?) gains and memset to zero
The tool mp4chaps by the following command
$ mp4chaps -i test.mp4
looks for the file "test.chapters.txt" to read the chapter marks
from. So removing the original file name extension (e.g. wav or flac)
makes it slightly more convenient for the user.
Players like vlc seem to stumble, if there es no chapter at the zero
position. As Ardour wouldn't let us put a track mark at the zero
position we can just use our header_func to put some kind of dummy intro
chapter. If a future version of Ardour allows track marks at zero, we
need to do a bit more work.
The mp4 file format supports chapter marks using the so called
mp4chaps format to enable chapter wise navigation in an mp4 file. The
format is like
hh:mm:ss.sss Chapter Title
This commit adds the ability to export those kind of chapter marks
along with TOC and CUE marks. The filename extension for the chapter
mark file is "chapters.txt". The format specification description is
"MP4ch".
Copy the 'Cut time' code from Mixbus, making a few obvious fixes to work in
A3 (e.g. nframes_t => framepos_t / framecnt_t).
Seems to work to move & remove markers, tempo & meter markers, and regions on
selected tracks.
Still TODO:
- use existing A3 'Insert time' dialogue
- make it respect 'No selection = all tracks'
- rename the command to something like 'Remove time' or 'Delete time': 'Cut'
sounds to me as if the removed range should end up on the clipboard ready
to be pasted somewhere, which of course it doesn't.
[Details] This bug does not show up when buffers are 16 byte aligned, but when they are not - this bug will lead to crash.
I tested all these functions with non-aligned buffers as well as long they do handle the situation with unaligned buffers.

-> click.
Mixbus in particular uses both types of tooltip so we might as well make them look the same.
N.B. The appearance is fine now on Windows but needs to be tested on the other platforms (i.e. some tweaking might be necessary).
All canvas objects share just one tooltip object which is based around Gtk::Label. The Label expands if the current tooltip text is wider than the previous text. However, it doesn't shrink again if the next tooltip has shorter text. Eventually, this results in some very strange looking tooltips (especially in Mixbus where they're used quite extensively).
Deleting the object after use will force a new object to get generated next time (at the correct size). There's still only ever one object per canvas but it's no longer persistent.
This reverts commit 6ba555c2f5.
which does not yet take monitoring states into account.
Ideally the case handled here should not happen in the
first place, It should be fixed in session_transport
transport_sub_state.
If there's port-latency > period-size, there is a
split cycle with (this_event->action_frame - _transport_frame).
Yet Session::check_declick_out() keeps PendingDeclickOut if
StopPendingCapture is set. The route declick’ed twice:
Once with the period-size and one with the remaining frames,
which resulted in a click.
fixes various fader zipper noise issues.
It voids sample accuate fader automation (the fader-gain
is low-pass filtered at 10Hz). Yet all musical purposes this
makes a lot more sense than sample accuracy anyway.
This does NOT work with MIDI files at present, because of SNAFU in SMF class, where end_write()
opens the file on its own, without _file_path being set. Needs some careful work, because basically
the SMF<=>SMFSource relationship is not tenable
* don’t allow to rename read-only sessions
* prevent periodic save (while rename is in progress)
* no renaming while actively recording (peak files
among other things will mess things up)
Lock was not held across a replace_{tempo,meter}() operation because of re-use
of {remove,add}_{tempo,meter}. Moved functional code into _locked variants so
that replace operation can hold lock across its entire active lifetime.
Made correct error handling for cases we didn't see before.
Removed redundant and experimental code I forgot to remove months ago.
Added debug output which will help in future testing

This works around a bug in OnsetDetector.
It requests a buffer of 1114 samples but later FFT
bails out if the buffer size is not a power-of-two.
Also large buffersizes fail.
Work-around: use ADAPT_ALL_SAFE (no buffersize
adapter), use a reasonably small buffersize.
The current settings work, even though it produces
the following warnings (vamp-plugins/OnsetDetect.cpp)
WARNING: OnsetDetector::initialise: Possibly sub-optimal step size for this sample rate: 512 (wanted 557)
WARNING: OnsetDetector::initialise: Possibly sub-optimal block size for this sample rate: 1024 (wanted 1114)
This commit should be reverted once VAMP/QM/aubio
is updated/fixed.
Technically it doesn't make much difference but from what I can tell, the only files which #include 'gtk2_ardour/gui_thread.h' are the source files from gtk2_ardour itself. The support libraries always #include 'gtkmm2ext/gui_thread.h' directly (which seems sensible). So for consistency's sake, let's keep it the same for libcanvas.
This moves MIDI channel filtering into a reusable class and moves filtering to
the source, rather than modifying the buffer afterwards. This is necessary so
that the playlist trackers reflect the emitted notes (and thus are able to stop
them in situations like mute).
As a perk, this is also faster because events are just dropped on read, rather
than pushed into a buffer then later removed (which is very slow).
Really hammering on mute or solo still seems to produce stuck notes
occasionally (perhaps related to multiple-on warnings). I am not yet sure why,
but occasional beats always.
Add "PERFORMER" to the exported .toc & .cue files based on the value of the
"album_artist" metadata field, and also use the value of the "album" field
for the TITLE if is set, falling back to the session or range name if it is
blank.
Invalidate all source entries from the image cache when we get our
region's DropReferences signal, while ignoring any subsequent regions with
no source.
Fixes bug #6166 (except record).
This attempts to follow the "current" control value somewhat aggressively:
* On locate, slider is set to the value from the top region at the new
transport position.
* Playback or MIDI input is followed "live".
* Whenever the slider is moved (including automatically), that value is emitted
as an immediate event to keep external gear in sync.
General idea is that the Ardour slider should act as a mirror of an external
hardware knob, and both should be synced to whatever the control is at the
current transport position. Since we lack real playback/touch/etc modes for
these for now, we must choose one behaviour, and this seems like the most
reasonable one.
Follow is handled in the audio thread, which is probably not ideal, but since
these controls have no lists and do not record, should be fine. Probably.
<oofus> rgareus: pre fader sends are not really used
for FX sends, they would either be sending to other
busses or to something like headphone/cue feeds.
You don't want those mixes having stuff muted in
them as you are muting you main mix.
ignore non-plugin processors for OSC
/ardour/routes/plugin/parameter
fixes issue with hidden internal processors. (rec-en
track adds a hidden [meter] processor at the top,
internal returns on busses have returns etc.)
Add an option to insert new routes at the top of the list ("First").
Reorder/rename the entries in the dialog.
Session's _order_hint is now the signed int it always wanted to be.
Fixes bug #6179. Top vs. bottom seems pretty arbitrary to me, and this solves
the obscuring issue (which is quite common since there are often PC events at
the start of MIDI files), so bottom it is.
When building with MSVC, some libraries had PROGRAM_NAME set to "Mixbus" and PROGRAM_VERSION set to "3". Whereas other libraries had PROGRAM_NAME set to "Mixbus3" while PROGRAM_VERSION was an empty string.
I've a horrible feeling there must have been a reason for this but I can't quite think what it was. Hopefully though, this change will standardize everything.
this is not a fix yet, just some comments and
code cleanup done while reading/investigating:
* limit reads to available write-space
* skip inactive tracks
* handle potential unsigned + negative value.
This breaks the build for windows builds that don't use the pthreads_win32
library. Using the opaque pthread_t type like this is probably not a great
idea. Using PBD::pthread_name is another option that I've used elsewhere
that seems more useful.
