From 6a8076f0c7dc04a69e28fa455954266bfb0e9613 Mon Sep 17 00:00:00 2001 From: Rob Morgan Date: Tue, 30 Dec 2025 08:45:00 +0800 Subject: [PATCH 01/38] feat: Add DJ module with dual-deck playback and beat analysis MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Introduces a new halo-dj crate with comprehensive DJ functionality: - Dual-deck audio playback with separate stereo outputs (external mixer mode) - BPM detection and beat grid analysis using FFT - SQLite library for track management with waveform caching - Hot cues and cue points for live performance - Tempo sync between decks with master deck selection - MIDI controller support (TRAKTOR Z1 MK1 mappings) - Lighting integration via RhythmState sync Core changes: - Add DJ commands to ConsoleCommand for deck control - Extend ModuleEvent with DjCommand routing - Add tempo source (Internal/DJ) to RhythmState - New DJ panel in UI with deck controls and library browser 🤖 Generated with

charset=UTF-8 Content-Transfer-Encoding: 8bit The DJ module was not being registered with the module manager, causing all DJ commands (including folder import) to be sent to a non-existent module and silently ignored. Changes: - Add `register_module` method to LightingConsole to allow registering additional modules after construction - Add halo-dj dependency to the main halo crate - Register DjModule in main.rs before console initialization - Fix TrackId to i64 conversion in get_all_tracks_for_ui The database should now be created at ~/.halo/library.db when the DJ module initializes, and folder imports should work. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 --- Cargo.lock | 1 + crates/core/src/console.rs | 68 +++++++++++++++++++------ crates/dj/examples/analyze_track.rs | 33 +++++++++--- crates/dj/examples/beat_events.rs | 7 +-- crates/dj/examples/multichannel_test.rs | 53 ++++++++++++++----- crates/dj/examples/play_audio.rs | 14 +++-- crates/dj/src/library/analysis.rs | 4 +- crates/dj/src/library/import.rs | 6 +-- crates/dj/src/module/audio_engine.rs | 6 +-- crates/dj/src/module/deck_player.rs | 22 ++++---- crates/dj/src/module/mod.rs | 37 ++++++++++---- crates/halo/Cargo.toml | 1 + crates/halo/src/main.rs | 5 +- crates/ui/src/dj/deck.rs | 36 ++++++------- crates/ui/src/dj/library.rs | 23 ++++++--- crates/ui/src/dj/mod.rs | 5 +- crates/ui/src/lib.rs | 3 +- 17 files changed, 217 insertions(+), 107 deletions(-) diff --git a/Cargo.lock b/Cargo.lock index 4ca650b..c357d54 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -1832,6 +1832,7 @@ dependencies = [ "crossterm", "eframe", "halo-core", + "halo-dj", "halo-fixtures", "halo-ui", "log", diff --git a/crates/core/src/console.rs b/crates/core/src/console.rs index f170167..475d43e 100644 --- a/crates/core/src/console.rs +++ b/crates/core/src/console.rs @@ -124,6 +124,12 @@ impl LightingConsole { }) } + /// Register an additional module with the console. + /// Must be called before `initialize()`. + pub fn register_module(&mut self, module: Box) { + self.module_manager.register_module(module);

charset=UTF-8 Content-Transfer-Encoding: 8bit The import_folder function was using import_directory which only extracts metadata without running BPM analysis. Changed to use import_and_analyze_directory which performs full audio analysis including BPM detection, beat grid, and waveform generation. Also fixes missing frequency_bands field in TrackWaveform and ModuleEvent initializers. Note: Existing tracks in the database will still show 120 BPM. Re-import the music folder or clear the database to re-analyze. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 --- crates/core/src/console.rs | 6 ++- crates/core/src/messages.rs | 4 ++ crates/core/src/modules/traits.rs | 4 ++ crates/dj/src/library/analysis.rs | 8 ++++ crates/dj/src/library/database.rs | 2 + crates/dj/src/library/import.rs | 2 + crates/dj/src/library/mod.rs | 3 +- crates/dj/src/library/types.rs | 55 ++++++++++++++++++++++++ crates/dj/src/module/mod.rs | 71 +++++++++++++++---------------- crates/ui/src/state.rs | 8 ++++ 10 files changed, 124 insertions(+), 39 deletions(-) diff --git a/crates/core/src/console.rs b/crates/core/src/console.rs index 6245b9e..e03bb85 100644 --- a/crates/core/src/console.rs +++ b/crates/core/src/console.rs @@ -2171,18 +2171,20 @@ impl LightingConsole { position_seconds, });

charset=UTF-8 Content-Transfer-Encoding: 8bit Major improvements to DJ sync functionality: Master/Sync buttons: - Master button now sends DjSetMaster command to backend - Sync button sends DjToggleSync and triggers immediate BPM sync - Buttons maintain visual state (lit when active) BPM loading fix: - Beat grid now properly passed to DeckPlayer (was only on Deck state) - Fixed in track loading, cached waveform loading, and analysis completion - Tracks now display correct analyzed BPM instead of 120 default Beat phase alignment: - Sync now jumps to align bar phase with master deck - Wraps phase difference to find shortest path to alignment Continuous sync (drift prevention): - Added sync_enabled, sync_correction, base_playback_rate to DeckPlayer - Audio engine calculates phase diff and applies proportional correction - update_sync_corrections() called 30Hz from rhythm interval - Correction limited to ±2% to avoid audible pitch artifacts - Decks stay locked together instead of gradually drifting 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 --- crates/dj/src/module/audio_engine.rs | 116 +++++++++++++++++++++++++-- crates/dj/src/module/deck_player.rs | 55 ++++++++++++- crates/dj/src/module/mod.rs | 83 +++++++++++++++---- crates/ui/src/dj/deck.rs | 2 + 4 files changed, 232 insertions(+), 24 deletions(-) diff --git a/crates/dj/src/module/audio_engine.rs b/crates/dj/src/module/audio_engine.rs index 1a570d0..fdabc93 100644 --- a/crates/dj/src/module/audio_engine.rs +++ b/crates/dj/src/module/audio_engine.rs @@ -285,27 +285,131 @@ impl DjAudioEngine { player.phrase_phase() } - /// Sync a deck to the master deck's tempo. + /// Update sync corrections for all decks with sync enabled. + /// + /// This should be called periodically (e.g., 20-50 times per second) to maintain + /// continuous beat lock between synced decks and the master. + pub fn update_sync_corrections(&self) { + let master = match self.master_deck() { + Some(m) => m, + None => return, // No master, nothing to sync + };

charset=UTF-8 Content-Transfer-Encoding: 8bit Implement beat-quantized loop functionality with 4-beat and 8-beat loop buttons plus a Reloop/Exit toggle. Loop IN point quantizes to nearest beat, loop OUT is calculated as IN + (beat_count × beat_interval). Features: - LoopState struct tracking loop_in, loop_out, active, and beat_count - BeatGrid helpers: nearest_beat() and beat_position_after() - Sample-accurate loop wrap detection in DeckPlayer - Loop region visualization in both overview and zoomed waveforms - Green tint when active, gray when inactive, with IN/OUT markers 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 --- crates/core/src/console.rs | 33 +++++ crates/core/src/messages.rs | 14 ++ crates/core/src/modules/traits.rs | 8 ++ crates/dj/src/deck/mod.rs | 34 +++++ crates/dj/src/library/types.rs | 64 +++++++++ crates/dj/src/module/deck_player.rs | 117 ++++++++++++++++ crates/dj/src/module/mod.rs | 99 +++++++++++++ crates/ui/src/dj/deck.rs | 209 ++++++++++++++++++++++++++++ crates/ui/src/dj/mod.rs | 10 ++ crates/ui/src/state.rs | 22 +++ 10 files changed, 610 insertions(+) diff --git a/crates/core/src/console.rs b/crates/core/src/console.rs index 292fdbf..58f66d5 100644 --- a/crates/core/src/console.rs +++ b/crates/core/src/console.rs @@ -1968,6 +1968,30 @@ impl LightingConsole { ) .await;

charset=UTF-8 Content-Transfer-Encoding: 8bit Move track analysis (BPM detection, waveform generation) to background thread pool using tokio::task::spawn_blocking() to keep UI responsive. Changes: - Add analysis_handle, analysis_progress_rx, current_analysis_track fields to DjModule for tracking background tasks - Create start_next_analysis() that spawns analysis with streaming waveform callback via unbounded channel - Refactor run loop to poll for progress (non-blocking try_recv) and completion (non-blocking is_finished) - Fix batch counter logic in import_folder/reanalyze_track to properly accumulate when adding to existing queue - Remove old blocking process_analysis_queue_item() function - Improve beat grid detection with bass-frequency onset detection (40-200 Hz) for better kick drum/downbeat alignment 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 --- crates/dj/src/library/analysis.rs | 308 +++++++++++++++++++++++++++--- crates/dj/src/module/mod.rs | 277 ++++++++++++++++++--------- 2 files changed, 470 insertions(+), 115 deletions(-) diff --git a/crates/dj/src/library/analysis.rs b/crates/dj/src/library/analysis.rs index 506a6f2..a31fe8a 100644 --- a/crates/dj/src/library/analysis.rs +++ b/crates/dj/src/library/analysis.rs @@ -1,6 +1,6 @@ //!

Remove `bpm` field from BeatGrid struct - BPM now only stored in tracks table - Add `bpm` field to AnalysisResult for analysis output - Add `base_bpm` field to DeckPlayer for playback calculations - Update BeatGrid methods to take bpm as parameter - Beat positions recalculated on-the-fly from first_beat_offset and track.bpm Also includes: - Fix beat grid nudge only working once (sync condition bug) - Add Set Downbeat button to set first beat at current position - Add Beat Shift buttons (+/- 1 beat) for grid adjustment - Fix BPM edit not refreshing library list or loaded deck - Fix track loading at wrong BPM (pitch/playback_rate not reset) Co-Authored-By: Claude Opus 4.5 --- Cargo.lock | 181 +++++++++- crates/core/src/console.rs | 39 ++- crates/core/src/messages.rs | 13 + crates/core/src/modules/traits.rs | 1 + crates/dj/Cargo.toml | 1 + crates/dj/examples/analyze_track.rs | 2 +- crates/dj/examples/beat_events.rs | 7 +- crates/dj/src/deck/mod.rs | 8 +- crates/dj/src/library/analysis.rs | 274 ++++++++++++--- crates/dj/src/library/database.rs | 73 ++-- crates/dj/src/library/import.rs | 8 +- crates/dj/src/library/mod.rs | 2 +- crates/dj/src/library/types.rs | 98 +++--- crates/dj/src/module/audio_engine.rs | 76 +++++ crates/dj/src/module/deck_player.rs | 140 +++++++- crates/dj/src/module/mod.rs | 478 ++++++++++++++++++++++++--- crates/ui/src/dj/deck.rs | 253 +++++++++++--- crates/ui/src/dj/library.rs | 2 +- crates/ui/src/dj/mod.rs | 12 +- crates/ui/src/state.rs | 12 + 20 files changed, 1418 insertions(+), 262 deletions(-) diff --git a/Cargo.lock b/Cargo.lock index a75e715..ec313cc 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -206,6 +206,15 @@ dependencies = [ "libc", ] +[[package]] +name = "ansi_term" +version = "0.12.1" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "d52a9bb7ec0cf484c551830a7ce27bd20d67eac647e1befb56b0be4ee39a55d2" +dependencies = [ + "winapi", +] + [[package]] name = "anstream" version = "0.6.18" @@ -574,12 +583,65 @@ dependencies = [ "zbus", ] +[[package]] +name = "atty" +version = "0.2.14" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "d9b39be18770d11421cdb1b9947a45dd3f37e93092cbf377614828a319d5fee8" +dependencies = [ + "hermit-abi 0.1.19", + "libc", + "winapi", +] + +[[package]] +name = "aubio-rs" +version = "0.2.0" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "9189fd9d8af82083a442e8b73ce12e602a6719f7360cf53f0bb9cb9e8c8d5a87" +dependencies = [ + "aubio-sys", +] + +[[package]] +name = "aubio-sys" +version = "0.2.1" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "99ef2dfeaceccd0b8a6d72203409acc927d9eebc8180c5756099549c9f8f20a8" +dependencies = [ + "bindgen 0.58.1", + "cc", +] + [[package]] name = "autocfg" version = "1.4.0" source = "registry+https://github.com/rust-lang/crates.io-index" checksum = "ace50bade8e6234aa140d9a2f552bbee1db4d353f69b8217bc503490fc1a9f26" +[[package]] +name = "bindgen" +version = "0.58.1" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "0f8523b410d7187a43085e7e064416ea32ded16bd0a4e6fc025e21616d01258f" +dependencies = [ + "bitflags 1.3.2", + "cexpr 0.4.0", + "clang-sys", + "clap 2.34.0", + "env_logger 0.8.4", + "lazy_static", + "lazycell", + "log", + "peeking_take_while", + "proc-macro2", + "quote", + "regex", + "rustc-hash 1.1.0", + "shlex", + "which", +] + [[package]] name = "bindgen" version = "0.71.1" @@ -587,7 +649,7 @@ source = "registry+https://github.com/rust-lang/crates.io-index" checksum = "5f58bf3d7db68cfbac37cfc485a8d711e87e064c3d0fe0435b92f7a407f9d6b3" dependencies = [ "bitflags 2.9.4", -

The new multi-method approach runs three detection algorithms and selects the best result based on agreement and confidence.
