Converting clip gain to volume (and baking volume into clip gain)
evaluated the clip's gain envelope by walking it from the start for
every breakpoint being converted, so a large envelope in an opened or
imported session cost envelope points squared and blocked the engine.
Build a running-maximum index over the envelope once per clip and
binary-search it. It returns exactly what the walk returned, including
for envelopes stored out of order.
* Tempo map: index tempo segments so tick/sample conversions are O(log n)
Every tick<->sample conversion walked all earlier tempo changes, so code
that converts many positions (MIDI import/export, the tempo ruler, score
layout, MIDI scheduling and controller chasing on the audio thread)
cost positions x tempo changes. A session or MIDI file with many tempo
changes and many notes or tracks could stall the engine or the audio
callback.
TempoMap now keeps the elapsed time at each tempo change (rebuilt on
every edit and on deserialize, never serialized) and binary-searches
the segment. MIDI scheduling also skips notes whose on and off both
fall outside the block before converting them.
* Tempo map: index a file's ticks with saturating subtraction
Bundle entries are stored, so the files read out of one can only
outgrow the bundle when several entries point at the same bytes. A
small bundle naming one payload thousands of times was copied out once
per name, up to the 1 GiB total limit, in the browser. Check the
archive for overlapping entry data before reading any entry.
When the aux/folder routing has a cycle, processing_order sorted the
auxes by a bounded feeder depth recomputed inside the sort key: each
evaluation re-searched every aux's output and sends against a growing
list of inputs, for up to eight hops, on every comparison. A session
with many auxes sharing buses made that cubic during audio sync.
Compute the same capped depth for every track at once: per hop, collect
the buses written by auxes reached so far, then mark the tracks reading
them. The result matches the old search (tested against it on a mixed
graph with cycles) and the sort uses it by lookup.
apply_params searched all of the track's automation lanes for every
stored insert parameter on every block, so a session with many
parameters and many lanes multiplied the two on the audio thread.
Collect the slot's lanes once per block, order them by parameter name
(keeping the first lane per name, the one the old search found) and
walk them alongside the sorted parameter map. The lane list reuses a
scratch buffer kept on the plugin slot.
libloading 0.9 prints only "dlopen failed" ("dlsym failed", "LoadLibraryExW
failed") and keeps the dlerror text or the Windows error as the error's source.
The CLAP and VST3 loaders formatted the error alone, so a plugin built for a
newer glibc was reported as "dlopen failed" with no reason. Append the source.
* MIDI: index controller dedup by channel and kind
Remove Duplicate Notes rescanned every controller already kept at the
same tick for each incoming one. A session whose sequence holds one tick
with many distinct channel/controller pairs made that quadratic and
blocked editing. Track where each channel+kind sits at the current tick
in a map instead; the last event per key still wins.
* MIDI: tag dedup index entries with their tick instead of clearing per tick
Clearing the map on every tick change cost O(capacity) per tick after a
dense tick. Store the tick with each entry and treat entries from an
earlier tick as absent. Add an oracle test comparing against the
previous per-tick rescan on mixed-tick input.
Its help said `<plugin id>`, but it only runs built-in plugins, and a
hosted id (clap:, vst3:, au:) failed as "unknown process". The help now
says built-in plugin id, and a hosted id gets an error saying AudioSuite
runs built-in plugins only.
Fixes#1301.
Bounces passed no bwf to the encoder, so mix and stem WAVs had no bext
chunk and post tools placed them at zero. Bounce::new now stamps them
with TimeReference = the session's timecode start plus the bounce start,
in samples since midnight, as other DAWs do. A caller's own bwf wins;
AIFF and FLAC have no bext and are unchanged.
Fixes#1296.
* clap-host tests: scan a freshly created private directory for the garbage-file test
The test reused a PID-named directory under the shared temp dir after ignoring a
failed cleanup, then loaded every .clap candidate in it. Another local account
could pre-create that directory and plant a native library that the test runner
would load. Create the directory exclusively (mode 0700 on Unix) and fail
instead of reusing one that already exists.
* clap-host tests: create the garbage-file test directory beside the test binary, not under TMPDIR
An integration test creates send C while send A's window is open: the window moves to the new send
with its fader on screen, and undoing the send closes it. send_route_menu now opens the window only
after the send command succeeds, without the extra bool, and its comment says reassignment leaves
the window alone.
Picking a destination for an empty send slot, or making one with new bus..., now opens that send's Send window, as in Pro Tools. Moving an existing send to another bus leaves the window as it was.
Bounces ran VST3 plugins with processMode kRealtime and never set
clap.render, so plugins that work differently offline never could.
Offline renders now create their plugins with Plugin::set_offline(true):
VST3 plugins get kOffline in setupProcessing and in every process call,
and CLAP plugins with clap.render are set to CLAP_RENDER_OFFLINE.
Playback stays realtime.
Fixes#1289.
The two link toggles shared the "link" icon (#1262), and Insertion Follows
Playback, although it works with N, had no toolbar button of its own and no
shortcut in the Options menu (#1263).
- icons: "link_track" draws the chain under two track rows so the track link
reads apart from the timeline link; "insertion_follows" draws the insertion
line and the playhead arrow it follows.
- toolbar: the option toggles move into option_toggles, which gains the
insertion-follows entry between the links and Mirrored MIDI, as in Pro Tools.
- options: the Insertion Follows Playback menu item shows N, the key it uses.
- test: option_toggles_have_distinct_icons fails when any two option toggles
share an icon (it fails on the old "link" pair).
Fixes#1262, fixes#1263
