Gitea #51 ROOT CAUSE: LoopAtWill was mapped to "loop forever", arming 224 of 603 samples as endless OpenAL sources
SAURON's "coolant flush sound glitched and perma" is one instance of a systemic
defect. SetupPatch (L4AUDLVL.cpp) decided looping from the SAMPLE flag alone:
AL_LOOPING = (info.loop != ForceStatic)
That armed every non-ForceStatic sample -- 224 of the 603 authored zones,
including unmistakable one-shots -- as an OpenAL source that never ends on its
own. Any such sound whose note-off never arrives plays forever. Measured 1946
LoopAtWill x Transient arming events in one short session.
The sample flag expresses PERMISSION; the SOURCE decides. Three facts [T1]:
* the enum's own comments (L4AUDLVL.h:14-19) -- LoopAtWill = "will play once
OR LOOP AS DESIRED", ForceStatic = "plays only once EVEN IF LOOPED" (a
veto), LoopAlways = "ramp up and then down";
* LoopAtWill is enum value 0, i.e. the DEFAULT an unauthored sample receives
(WTPresets.cpp:37) -- it cannot mean "loop forever";
* LoopAlways, the real always-loop, is used by ZERO shipped samples.
"As desired" is the source's authored AudioRenderType (Transient=one-shot vs
Sustained=held), streamed from AUDIO*.RES (AUDLVL.cpp:28) and already consulted
by the renderer (L4AUDRND.cpp:567, AUDREND.cpp:184). SetupPatch now takes it,
threaded from all three L4AudioSource call sites (Direct/Dynamic3D/Static3D).
New rule: LoopAlways->1, ForceStatic->0, LoopAtWill->the source's render type.
MEASURED before changing behaviour (BT_LOOP_AUDIT=1, scratchpad/loopaudit.py):
LoopAtWill x Transient -> loop=0 (was 1) 1946 events
LoopAtWill x Sustained -> loop=1 unchanged 65 events
ForceStatic x Transient -> loop=0 unchanged 292 events
The engine loops (EngineAccel07_z0..z2, EngineMotor01, EnginePower01) are all
LoopAtWill/Sustained and PRESERVED -- no regression there. All 24 reclassified
samples are genuine one-shots: laser charge/fire/explosion/loaded, missile
loading, engine shift, coolant pressure inc/dec.
A/B PROOF (scratchpad/loopab.py, same session both arms, only BT_LOOP_LEGACY
differs), asking the engine's own BT_AUDIO_DUMP what is still playing with
loop=1 long after every release:
[legacy] EnginePower01, CoolantPresInc03_z2, CoolantPresDcr03_z2
[fixed] EnginePower01
The two stuck coolant sources are the reported symptom. They were eventually
reclaimed when a later trigger reused the source, which is why the bug was
intermittent -- the "perma" case is when nothing else retriggers it. The fix
removes the mechanism.
BT_LOOP_LEGACY=1 restores the old rule for a field A/B without a rebuild. The
layers to listen to are the beam sustains: LaserA/CSustain* are authored
LoopAtWill on a TRANSIENT source, so they now end with the sample instead of
looping until note-off. The render type is T1 authored data; the interpretation
that LoopAtWill defers to it is a strong reading of the enum + defaults rather
than a disassembled statement, and is flagged as such in the KB.
Plausibly bears on #32 (audio cutting in/out late in a match): a stuck looping
source holds its pool slot for the rest of the round.
Rigs: scratchpad/flushsnd.py (flush start/stop pairing), flushsnd2.py (stuck-
source hunt), loopaudit.py (the classification matrix), loopab.py (the A/B).
KB: context/wintesla-port.md audio section, context/decomp-reference.md env
table (BT_LOOP_AUDIT / BT_LOOP_LEGACY / BT_AUDIO_DUMP / BT_AUD_TAIL),
docs/AUDIO_FIDELITY.md F38. checkctx.py CLEAN.

Remote operator control channel + THE teardown crash root-caused and fixed
REMOTE OPERATORS (dev-channel ask): the relay grows a control TCP listener (console port + 7) speaking a line protocol -- AUTH <secret> (auto-generated content\operator_secret.txt), then launch / stop / ping / get mission / set key=value;... The relay's timestamped log stream tees to the authenticated operator (bounded per-conn buffers -- a stalled operator can NEVER stall the relay; overflow = drop), with a 400-line history replay on connect so mid-session operators see current state. One operator at a time; a new AUTH displaces the old. stdin commands unchanged (rigs/GUI local mode untouched). The operator GUI gains a 'Relay host' field: blank = today's local flow byte-for-byte (child relay dies with the window); a hostname = drive that machine's relay remotely (launch/stop/apply-settings over the wire, roster rebuilt from the teed log, local-instance joins point at the remote relay). Only the relay host needs port forwarding. Scripted protocol test: auth reject/accept, takeover, get/set, ping, history replay, and a FULL 2-node mission launched and stopped entirely over the socket. CRASH FIX (the layout-shifting heisenbug -- and almost certainly issue #35): the new crash self-report finally captured its 24-frame stack: InterestManager::OrphanInterestOrigin -> RemoveUninterestingEntity -> DestroyEntityAudioObjects -> {Static,Dynamic}3DPatchSource:: IsAudioSourceClipped, AV reading NULL+0x38 -- the unguarded chain GetMissionPlayer()->GetPlayerVehicle()->GetSimulationState() (the authentic burning-mech death-silence check) hit a NULL vehicle during MP teardown windows. Both sites now null-guard; burning semantics preserved whenever the vehicle exists. Also live-confirms that interest-based entity teardown RUNS in MP (the #38 paint mechanism). Regression: full combat round + control-channel drive, zero crashes. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> |

Audio-dropout fix: OpenAL source-pool lifecycle (uninit aliasing, atomic-delete leak, stranded partials)
Field report: audio cutting in and out toward the end of the match. Three structural defects in the port's source-pool lifecycle: 1. SourceSet.sources[] was uninitialized heap garbage until first acquisition -- AL names are small ints, so a recycled-heap slot could alias a LIVE source owned by another sound; alIsSource() skipped generation, two sounds shared one source, and whichever released first deleted the other's mid-play. SourceSet ctor now zero-inits. 2. ReleaseSourceSet's bulk alDeleteSources(count, sources) is ATOMIC on invalid names (AL spec) -- one empty/-1 slot and NOTHING deleted; after the first pool exhaustion every partial release leaked and the pool never recovered. Now per-slot guarded delete, slots parked at 0. 3. Failed acquisitions stranded partial sets forever (dropped transients are never released by anything). ReleaseChannels() handback at both failure sites (StartRequest + dormant-resume) + a dtor backstop. Verified: 2-node MP smoke (mission + lobby-loop relaunch clean, census live/acquireFails 0/0) + 100s solo combat smoke (52 audio triggers, zero AL errors). Awaiting live playtest confirmation at scale. KB: context/wintesla-port.md audio-dropout section. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> |

Death-crash FIXED: 25-voice explosion preset overflowed the 5-slot audio SourceSet (Gitea #12)
The weekend's crash family root-caused under cdb: SourceSet.sources[5] receives the AllExplosion death preset's 25 streamed voices -- RequestAudioChannels wrote 20 OpenAL source ids past the array, smashing the neighbouring heap object (Release: a vtable overwritten with a source id -> delayed silent AV at AudioControlEvent::Send; Debug: CRT heap- corruption abort in the death Explosion's audio teardown). Explains all three #12 crash flavors (solo enemy kill -- stack-confirmed; MP self- death; MP peer PEER_DOWN cascade -- same generic teardown). Fix: sources[] sized to AUDIO_SOURCESET_CAPACITY=25, static_assert lockstep with MAX_PRESET_SAMPLES, + defence-in-depth clamps at the ctor and acquisition sites. Soak: 26+ deaths across glass AND pod builds under cdb, zero faults, full wreck lifecycle every time. Gotchas S21: the fixed-array-vs-streamed-count overflow class + sweep note. Awaiting human verification: the MP death-and-survive session. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> |

Audio Phase 3 (AUDIO_FIDELITY F9/F11/F12): EFX lowpass + reverb split + cockpit placement
New L4AUDEFX bridge (OpenAL Soft ALC_EXT_EFX): one EAXReverb aux slot at the authentic AUDIO.INI global_reverb_scale (0.3) + a scratch AL_FILTER_LOWPASS (params copied at attach). F9 filters (was: computed then thrown away -- everything full-bright at all distances): Dynamic3D ExecuteModel drives GAINHF from highFreqCutoffScale x brightnessScale x maxMIDIFilterCutoff, UNGATED (decomp part_008.c:7496, 7589-7604 -- every moving 3D sound dulls with distance per the AUDIO.INI knee-60/exp-2.0 model); Static3D from brightness x max (:7831-7884); Direct inside its existing gated NRPN-rate block. AWE 100-8000 Hz curve -> EFX 5 kHz-reference gainhf via a 2-pole approximation [T3 curve, endpoints exact]. F11 reverb (was: bone-dry everywhere): 3D patch sources attach an aux send at Start, exactly where the original sent CC91 = global_reverb_scale (part_008.c:7278-7394); Direct cockpit sources keep CC91=0 -- dry. The wet-exterior vs dry-cockpit contrast is back. F12 placement (was: every cockpit sound dead-center): DirectPatchSource Start places sources by the authored 6-value position enum (front/rear card + pan CC10, decomp @00463848/@004638a8) as listener-relative directions, composed with the zone L/C/R pan. New PatchResource GetBankID/GetPatchID pass-throughs (the LOD accessor is protected). Regression (35s drive+fire): EFX READY, stable, deliveries unregressed, no AL errors.

Audio Phase 2 (AUDIO_FIDELITY F1/F2/F13/F14): full-zone soundbank -- key-splits,
layers, baked tuning, loop regions, release fades Extractor rewrite (tools/sf2extract.py): every sample-bearing instrument zone becomes a SAMPLEINFO slot -- 603 zones / 241 presets (68/115 + 94/126 multi- zone, matching the audit exactly). Per zone: keyRange(43), sampleModes(54), SBK samplePitch(55) + rootKey(58) + coarse/fineTune(51/52), attenuation(48, INVERTED SBK scale, 0.375 dB/step [T3], baked into the PCM), releaseVolEnv(38), pan(17), shdr loop region. F2 pitch (algebraically exact): WAV rate = round(44100 * 2^(((6000 - rootCents) + tune)/1200)) -- EMU8000 v1 base 44100. Cross-checks: FootFall 17300 Hz (the audit's +4.2 st), MissileLoaded low zone 88200 (-24 st), Warnings01 8-way klaxon split w/ 3 looped zones, Death01 162 Hz extremes. F1 zone selection: SetupPatch/PlayNote take the authored note; attach/play only zones whose [keyLo,keyHi] contains it (detach the rest so a rewound source can't replay a stale buffer). Live-verified: LaserLoaded/ MissileLoaded note 36 -> low clunk zone, note 84 -> high blip zone (pitch 4); LaserCFire plays all 3 authored layers incl the looping sustain. Stereo-pair zones pan via listener-relative AL_POSITION (distance model is AL_NONE). MAX_PRESET_SAMPLES=25 (AllExplosion); fixed PRESET_isImplemented's >=5 bound. F13 loops + releases: authored [loopStart,loopEnd] applied via AL_SOFT_loop_points at buffer load (0 rejections; kills the latent boom-loop on MechExplosion's 1.5% sustain slice + the ~2.4 Hz LaserBSustain wrap tick); StopNote now honors the authored releaseVolEnv (1.1-3.9 s on ~20 looping presets) with a dB-linear fade serviced from AudioHead::Execute; restarts reclaim fading sources. One-shots keep the instant stop (faithful). Regression (40s drive+fire): stable, loop points accepted, key-splits + layers verified in the delivery trace, chirp still dead, footfalls fire.

Audio Phase 1 (AUDIO_FIDELITY F3/F4/F10/F15/F18/F20 + KB): the quick wins
F3 distance: alDistanceModel(AL_NONE); restored the commented authored distance multiply in Dynamic3D::CalculateSourceVolumeScale, added the same override to Static3D, dropped the (now inert) AL_MAX_DISTANCE writes. Far battle audio follows the authored knee/rolloff curve again, and the volume cull / voice steal / ducking chains are distance-aware. F4 volume law: AL_GAIN = volume_scale^2 at all 3 per-frame sites (Direct/ Dyn3D/Static3D) -- the GM CC7 squared curve; linear was ~+6 dB at mids. F10 doppler: alDopplerFactor(0) (AL's model ran wrong constants + sign- inverted velocity: approaching sources pitched DOWN); the AUTHORED dopplerCents (AUDIO.INI range/speed-of-sound model, decomp-proven consumer part_008.c:7466) now adds into the Dynamic3D pitch chain. F15 ConfigureActivePress: published at the MechSubsystem BASE (binary id 2, descriptor @0x50de5c -> +0x110); renamed the misnamed vitalSubsystemIndex member (the weapon ConfigureMappables handler already drives it 0/-1). Removed the invented Sensor/Myomers duplicates and RESTORED their byte- exact layouts (0x328/0x358 allocs + asserts). MechWeapon's pinned-id pad absorbed the +1 chain shift -- which matches the binary's own numbering. F18 cook-off warning: AmmoBin FireCountdownStarted -> the existing cookOffArmed @0x18C (binary table @0x512600); the countdown klaxon can fire. F20 zoom blip: L4MechControlsMapper publishes TargetRangeExponent -> the live @0x1a4 zoom member (own table chained to MechControlsMapper). KB: replaced the bogus divisionParameters+0x10 rate read with SystemClock::GetTicksPerSecond() (FUN_0044e19c is GetFrameRate -- original audio frames were CLOCK TICKS). Regression (35s drive+fire): stable; ConfigureActivePress binds real on all 9 subsystems (idle -1, zero pad redirects); FireCountdownStarted + TargetRangeExponent bind live members; attrnull 53 -> 41; chirp still dead; footfalls still fire (gain now correctly squared).

Audio: implement NOTE->PITCH + control pitch -- the AL_PITCH was never applied (task #50)
The whole pitch system existed but was discarded: NoteAudioHandler captured the
MIDI note, ExecuteModel computed relativePitch from the control-chain cents --
and NOTHING ever called alSourcef(AL_PITCH). Every sample played at root.
Consequences fixed:
- The load-time 'chirping' ambience: an authored looped sequence (div=120
tempo=160, note 51 events on bank1:83) plays a rhythmic tick pitched ~9
semitones DOWN; at root it was a high click ('chirp'). Identified live via
the new BT_AUDIO_DUMP playing-source tape + user ear-match at cadence.
- Engine now revs: EngineMotor pitch rides the throttle (measured 1.0 -> 1.12).
- All sequence-authored patterns (alarms/klaxons/ambience) regain their pitch.
Implementation: BTNotePitchFactor(note) = 2^((note-60)/12); applied at all 3
patch-source StartImplementations (fresh attach) and all 3 ExecuteModels
(combined with the control-chain relativePitch, clamped 0.5..2.0 as before).
Uses the existing AudioSource::GetCurrentNoteValue().
Also: [seqcfg] sequence-config dump, g_bufferNames + BT_AUDIO_DUMP live tape
(1/s: every playing AL source with sample name/gain/pitch/loop),
tools/soundboard.py updated mapping.

Audio: restore the dropped ExecuteWatchers poll -- polled audio watchers were ALL dead (task #50)
User: "when I start moving all the sounds fade away, no footsteps." Diagnosis chain (all empirical, BT_AUDIO_SPATIAL/BT_ATTRBIND_LOG traces): - The audio head DOES track the mech (listener-relative positioning verified while driving) -- not a spatial bug. - The idle sounds correctly STOP on leaving the standing state; the MOVING sounds never started because every POLLED audio watcher was dead: the reconstructed Mech::PerformAndWatch replaced the engine performance but dropped the ExecuteWatchers() step from the engine tail (Simulation:: PerformAndWatch = Perform -> ExecuteWatchers -> WriteSimulationUpdate). Only PUSHED StateIndicator watchers (SetState->Execute) ever fired -- which is exactly why state sounds worked but footsteps/motion-scaled audio didn't. FIX: poll ExecuteWatchers() (AreWatchersDelayed-gated) before the update write. Immediately unlocks the polled family: MissileLoaded01/LaserLoaded01 ready dings, ProgramButton01, motion scales (PlayNote 15 -> 30 per run). - FootStep (0x1e) backed REAL: was the inert attrPad (an AudioLogicalTrigger polls it -- threshold-crossing pulse per foot plant). New footStep member, pulsed by SetBodyAnimation on entering any locomotion clip 1..0x17 (runtime stride alternation MEASURED as body states 12<->13 -- the enum-name numbering does not match runtime clip ids), decayed by IntegrateMotion (~1/3 s). - Footstep volume is speed-scaled (AudioMotionScale on LocalVelocity): at standstill the transient start computes volume 0 and the renderer drops it (LowAudioVolumeThreshold) -- so footfalls are audible at real walking speed. Diagnostics kept (BT_AUDIO_SPATIAL): spatial dist/vol per source, CLIPPED/DROP/ START at the request gate, vol=0 factor breakdown, scale->0 sends, trigger notifications, watcher poll-rate probe.

Initial commit: bt411 -- standalone Windows BattleTech (Tesla 4.10 port)
Clean, self-contained extraction of the BattleTech-specific work from the
reverse-engineering workspace -- engine + game + content + build, with nothing
from Red Planet or the raw archive dumps. Builds green (Win32) and runs the
single-player drive->animate->target->fire->damage->destroy loop out of the box.
Layout:
engine/ MUNGA + MUNGA_L4 shared 2007 engine, carrying our BT render/loader
work (bgfload/L4D3D/L4VIDEO: BSL bit-slice decode, LOD/ground/shadow
models) + image codec; the minimal rp/ headers the audio HAL needs
game/ reconstructed BT logic + surviving-original BT source + fwd shims
+ WinMain launcher
content/ full runtime tree (BTL4.RES, VIDEO/, GAUGE/, AUDIO/, eggs, BTDPL.INI)
docs/ format specs + reconstruction ledgers
reference/ raw Ghidra pseudocode (recon source-of-truth) + decomp exporter
tools/ MP console emulator + map/resource scanners
One top-level CMake builds munga_engine lib + bt410_l4 game lib + btl4.exe.
All paths relativized (186 fwd shims + ~437 CMake abs paths -> repo-relative);
DXSDK is the one external, overridable via -DDXSDK. Verified: builds to a
byte-identical 2.27MB exe and runs combat (TARGET DESTROYED, 0 crashes) against
the bundled content.
