feat: add SOTA multi-engine architecture, duet separation, and precis… - #328
Included review availability: This review used your included allowance. Your plan provides up to 4 included reviews per hour; 3 remain after this review.
Walkthrough
The pull request adds configurable audio-separation, transcription, alignment, pitch, and MIDI engines. It adds lyric and timing tools, duet assignment, expanded UltraStar output, a comparison benchmark, Docker Compose configuration, and updated documentation.
Changes: Speech and Lyric Processing
Layer / File(s)
Summary
Transcription and genre profiles src/modules/Speech_Recognition/TranscribedData.py, src/modules/Speech_Recognition/genre_profiles.py, src/modules/Speech_Recognition/Whisper.py, pytest/modules/Speech_Recognition/test_genre_profiles.py
Transcription data now stores character timings and line-end markers. Genre profiles provide language-specific prompts and settings used by Whisper transcription.
Vocal classification and lyric alignment src/modules/Speech_Recognition/fuzzy_lyric_matcher.py, src/modules/Speech_Recognition/lyrics_aligner.py, src/modules/Speech_Recognition/mms_aligner.py, pytest/modules/Speech_Recognition/*
New functions classify vocalizations, filter intro ad-libs, align transcription with reference lyrics, distribute missing-word timings, repair timing runs, and optionally use MMS-FA or WhisperX alignment.
Syllabification and hyphenation src/modules/Speech_Recognition/syllabifier.py, src/modules/Speech_Recognition/hyphenation.py, pytest/modules/Speech_Recognition/test_sync_10_10.py
Language-region selection and Spanish and English syllabification rules are added to the hyphenation path.
A separator interface and factory select Demucs, BS-Roformer, Mel-Roformer, SCNet, or HTDemucs implementations. Separation accepts model and de-reverb settings.
New audio functions detect and refine onsets, calibrate transcription timing, trim syllable boundaries, estimate tempo and key, and create click tracks.
Spatial analysis and duet assignment src/modules/Audio/stereo_vocal_analyzer.py, src/modules/Audio/duet_separator.py, pytest/modules/Audio/test_duet_separator.py, pytest/modules/Audio/test_vocal_taxonomy.py
Stereo metrics and phrase features support lead/backing analysis and two-player phrase assignment, with optional ECAPA embeddings.
Pitch extraction and MIDI generation src/modules/Pitcher/Extractors/*, src/modules/Midi/Extractors/*, src/modules/Midi/midi_creator.py, pytest/modules/test_plan_fixes.py
Pitch and MIDI factories select available extractors. MIDI creation adds melisma segmentation, octave correction, audio-derived velocity, and pitch bends.
UltraStar conversion supports octave offsets, duet tracks, player markers, updated beat and note writing, and genre formatting. The parser reads genre, year, and language tags.
Pipeline and CLI Integration
Layer / File(s)
Summary
Processing settings and CLI options src/Settings.py, src/modules/common_print.py, src/UltraSinger.py, pytest/modules/test_multi_engine_selector.py
Settings and CLI parsing add engine selection and controls for timing, trimming, duet processing, metadata, and output options.
Song discovery and processing src/UltraSinger.py, src/modules/ProcessData.py, pytest/modules/test_musicbrainz_client.py
The pipeline supports song folders, audio and sidecar discovery, batch processing, genre and language selection, optional transcription export, and integration of the new audio, pitch, MIDI, duet, and output functions.
Benchmark, Runtime, and Documentation
Layer / File(s)
Summary
Synchronization benchmark src/modules/Benchmark/*
A command-line utility parses two UltraStar files, aligns syllables, calculates comparison metrics, and prints a report or writes JSON.
Container and dependencies Dockerfile, docker-compose.yml, pyproject.toml, .dockerignore, .gitignore, UltraSinger.code-workspace
The container installs additional audio and model packages, sets runtime paths and a named user, and defines mounted directories and GPU reservation. Dependency and ignore rules are updated.
Project documentation README.md
The README documents processing stages, directory conventions, engines, profiles, duet and melisma options, and audio-processing measurements.

Remove the manifest conflict between onnxruntime-gpu and the CPU onnxruntime that swift-f0 and rmvpe-onnx install.
pyproject.toml now requests onnxruntime-gpu==1.20.0 next to swift-f0==0.1.2 and rmvpe-onnx>=0.2.3. Both of those packages depend on the CPU onnxruntime distribution. A plain install from this manifest therefore installs both distributions into the same onnxruntime/ package directory. The Dockerfile works around this with a post-install uninstall and reinstall, but only for Docker builds. The non-Docker install scripts and the README perform no equivalent repair. On a GPU host, the default SwiftF0 pitcher can then fail at import, or the CUDA provider can be lost.
Choose one ONNX Runtime distribution in the manifest, or add an install step that removes the CPU package before installing onnxruntime-gpu. The Dockerfile's workaround cannot be written in pyproject.toml alone, so a manifest-only fix is not established by the inspected source.

Limit the autocorrelation to the BPM lag range.
compute_autocorrelation_tempo runs np.correlate over the whole onset envelope, but only lags between min_lag and max_lag are read.

Align the phrase-window docs and default with the 50 ms cap.
phrase_snap_window_ms defaults to 120 ms in src/Settings.py, and its docstring says it covers "up to 120-150ms." snap_transcribed_data_to_onsets clamps the effective phrase window to 50 ms. Any configured value above 50 ms therefore behaves the same as 50 ms, so the 120 ms default has no effect. Keep the 50 ms cap. It is a drum-bleed safety limit. Correct the docstring and the default so they state the cap.
Because the clamp already yields 50 ms for any input at or above 50 ms, setting the default to 50 ms does not change runtime behavior.

Preserve the selected SCNet engine.
When scnet is selected, separate_vocal_from_audio passes model.value (htdemucs) to SCNetSeparator. SCNetSeparator sends that value to BSRoformerSeparator, which can fail loading it and then falls back to another model. The resulting files are therefore not guaranteed to come from SCNet. Pass a supported SCNet model to an SCNet implementation instead of routing through the BS-Roformer fallback.

Use the MMS alignment output to compute acoustic word timings.
The MMS path ignores emission, tokenizer, and aligner. It assigns equal intervals and score: 1.0 to every word, then prevents WhisperX fallback. Lyric alignment and MIDI generation consume these intervals, so unequal-duration words and sustained vowels can produce inaccurate charts.

Replace the equal-duration timing and constant score logic in the `words` loop
with acoustic word timings computed from `emission`, `tokenizer`, and `aligner`;
derive character timings from those aligned word intervals. If MMS alignment
cannot produce valid timings, allow the existing WhisperX fallback instead of
treating the approximate intervals as a successful alignment.

Use a language-neutral prompt during automatic detection.
When language is None, the code selects the English vocalization suffix and passes it as initial_prompt before WhisperX detects the language. A Spanish song without a lyric-language override can therefore receive English conditioning, which may degrade transcription.

Use half-open windows so a boundary frame counts once.
detect_dominant_chords_timeline uses a closed right edge (t_arr <= next_t), and the next window starts at the same value (curr_t = next_t). A chroma frame whose time equals a boundary exactly is therefore added to both adjacent chord windows. The consumer appends both events unchanged. Use < for every window except the last, which must keep <= so the final frame is still included.

Set the pitcher default to rmvpe to match the README and pitch_engine.
A run without --pitch-engine or --pitcher reads settings.pitcher, which defaults to swiftf0. The README documents rmvpe as the default, and pitch_engine also defaults to rmvpe. The pitch stage never reads pitch_engine, so its default has no effect. If swiftf0 is the intended default, the README and pitch_engine must change instead.

Clear the cached onsets for the audio path before snapping.
_onset_cache is keyed only by audio path and is never cleared. A later song in the same batch run can receive an earlier song's onsets when both songs write the same vocals file and skip_cache_vocal_separation rewrites that file. Two cases produce this shared path: keep_cache is enabled and two songs have the same artist and title, so the second song reuses the first song's folder; or cache_override_path points to a shared folder. The snap then aligns syllables to the wrong boundaries.

Check the BIC-refined onset against the snap window.
After BIC refinement, the code accepts any result at or after prev_end_limit. It does not compare the result with the original syllable start. The refinement search covers about ±40 ms around the snapped onset, so the final onset can move about 75 ms from the original start with the default 45 ms window. The refined value should also satisfy the same window_sec bound used for candidate selection.
If the refined value fails this check, the code keeps the snapped target_start, which is the value it already uses when refinement is not applied.
Suggested fix
refined_t = refine_onset_with_bic(audio_path, target_start, window_ms=40.0)
- if refined_t >= prev_end_limit:+ if refined_t >= prev_end_limit and abs(refined_t - start) <= window_sec:
target_start = refined_t

Add the separation model to each cache path.
Each cache check below returns stems without checking which model produced them. When the cache folder is kept, a later run with a different model can reuse the earlier stems for the same song basename.
src/modules/Audio/separation.py:62-69: separate_vocal_from_audio checks separated/<strategy>/<song>/vocals.wav and no_vocals.wav before it calls a separator. When both files exist, the separator is skipped. A changed bs_roformer_model with the same strategy therefore returns the previous model's stems.
src/modules/Audio/Separators/mel_roformer_separator.py:33-40: MelRoformerSeparator returns from separated/mel_roformer/<song>/ before it delegates.
src/modules/Audio/Separators/bs_roformer_separator.py:58-66: BSRoformerSeparator returns from separated/bs_roformer/<song>/. Mel-Roformer and SCNet reach this check when their own outer checks miss. An SCNet request can therefore return BS-Roformer stems.

Forward skip_cache into the BS-Roformer and Mel-Band strategies.
With skip_cache=True, separate_vocal_from_audio still calls the strategy. BSRoformerSeparator.separate returns existing vocals.wav and no_vocals.wav before it runs audio-separator. Deleting the outer vocals_path and instrumental_path regenerates output only for the bs_roformer strategy. For mel_roformer, the strategy checks its own folder, then delegates to BSRoformerSeparator, which writes to and reads from the bs_roformer folder. If that folder already has files, they are returned again.

Make kim-vocal select Kim_Vocal_2.onnx when no model is passed.
Adding "kim-vocal" to MODEL_ALIASES does not change this. separate() reads the alias table with the caller's model_name. When model_name is omitted, the lookup key is "", which misses, so the call falls back to self.DEFAULT_MODEL. Define a subclass whose default is the Kim checkpoint, and map the alias to that subclass.
This affects direct get_separator() callers that omit model_name. The separation workflow passes model_name at separation.py:70-76.

When consecutive syllables are shorter than the minimum, previous_end_beat advances beyond each acoustic onset. The next note then starts at that delayed value, so lateness accumulates across rapid passages. Cap each note’s extension at the next segment’s written acoustic start.

Remove the ±24 clamp after convert_midi_note_to_ultrastar_note so
ultrastar_pitch preserves signed values outside the display range and distinct
notes retain their scored intervals.

Use the same segments for duet classification and writing.
The caller classifies the original segments, but the writer removes empty segments before regrouping and applying IDs by phrase index. A blank segment can hide a pause from the original grouping. Filtering can then add a phrase, so a later player-2 phrase receives the fallback player-1 ID and is written to the wrong duet track.

Update the duet phrase assignment in the writer to use the same segment grouping
and phrase boundaries used during duet classification, rather than regrouping
after empty segments are removed. Keep player IDs aligned with their classified
phrases so a later player-2 phrase is not assigned the player-1 fallback.

Include is_word_end when measuring pauses.
When a segment has is_word_end=True without a trailing space, the calculation ignores its pause and can return 0.45. Duet phrase grouping uses this threshold, so pauses between the measured value and 0.45 can change phrase grouping. Include the flag as an alternative word-end condition.

Reject aligner names outside the documented values.
mms_f is not a documented value, but the parser stores it without a check. Whisper selects MMS-FA when the value contains mms, so mms_f runs the MMS-FA path. A misspelled value without mms, such as mmfa, silently runs the default Wav2Vec2 path. Validate the value against wav2vec2 and mms_fa when it is parsed.

Key the BIC audio cache by file state, not only by path.
_get_audio returns cached audio for any path it has loaded before. When skip_cache_vocal_separation is enabled, separation regenerates the stem and copies it over vocals.wav at the same path. That path is shared when two songs in one run use the same cache folder, which happens with keep_cache and a reused song folder, or with cache_override_path. The next onset snap then uses the earlier song's audio, which can shift an onset by up to 40 ms.
Include the file's modification time and size in the cache key. Perform the file-state lookup inside the existing try, so a stat failure returns no audio.

Pick one onset anchor for calibration when several qualify.
detect_first_vocal_onset documents its return value as "the first vocal onset". When expected_start is set, it returns the detected onset nearest expected_start instead (src/modules/Audio/vocal_validator.py:98-100). The search starts 0.40 s before expected_start, so an earlier qualifying onset inside that window can be passed over. Calibration then moves the first transcription start, and the #GAP derived from it, to the later onset. This happens when the difference is within max_calibrate_ms.
Returning the earliest onset would match the docstring. It would also anchor calibration to any earlier vocal event in the window, such as an adlib that has no transcribed syllable. Choose the intended anchor:
If the first sung sound is the intended anchor, return detected_onsets[0] and add a test with two qualifying onsets.
If the onset nearest the transcribed lyric is the intended anchor, change the docstring to describe that behavior and add the same test.

Keep returned note timings non-overlapping after duration clipping.
When audio_duration is set and the last two notes reach it, clipping sets the first note's end to audio_duration. The second note's start then becomes audio_duration - 0.045, which is earlier than the previous note's end. The returned segments overlap by up to 45 ms. This breaks the non-overlap rule that the function applies before clipping.
The UltraStar writer moves such a start to the previous note's end, so the .txt chart does not keep the overlap. Code that reads start and end directly from the returned segments still receives the overlap.
The clipping branch runs only when a caller passes audio_duration. The CLI call at src/UltraSinger.py:503-506 reads media_info.duration, and the inspected MediaInfo class does not define that field.
Clamping the start to the previous end would extend the note past audio_duration. The fix must decide which boundary takes priority.

Update the duration-clipping branch so returned note segments remain
non-overlapping without extending past audio_duration. When moving new_start
back to preserve the final note’s duration, also reduce the preceding note’s end
as needed so it does not exceed new_start; keep audio_duration as the upper
bound for all returned timings.

Global octave clamp lowers high notes that their phrase does not support.
The global clamp at lines 421-422 subtracts 12 from any note at least 14 semitones above global_median. It does this before any phrase check. The phrase loop at lines 427-430 adds 12 back only when phrase_median is at least the note's original pitch. A high note in a phrase whose median sits below it therefore stays one octave down.
For example, with global_median at 60, a phrase of MIDI notes 60, 62, 63, 62, 60, 74 has phrase_median 62. The final 74 is lowered to 62. The neighbor check at lines 69-77 does not restore it. Phrases with fewer than three valid notes use global_median as phrase_median (line 52), so their high notes are never restored by the phrase loop.
The lowered notes reach the MIDI and UltraStar output. Phrases where most notes are high are restored correctly, so the octave error affects only high notes in low-majority phrases.
