Changes

Major

• Replaced the Legacy and Modern transcription backends with a newer accuracy-focused A2M Piano Engine.

• Redesigned GPU acceleration around explicit CUDA and DirectML choices.
• Added separate, system-aware CPU usage and GPU memory controls.

• Added independent CPU usage settings for CPU and GPU transcription.
• A2M now reduces GPU processing groups automatically when a selected memory level is unsupported.
• GPU setup now returns to the user's intended GPU selection after installing a required runtime pack, while failed provider changes restore the previous working configuration.
• Added a post-conversion MIDI summary showing note count, duration, pitch range, pedal count, processing time, and save location.

• Improved cancellation and lower-memory audio decoding for large or less commonly supported audio files.
• Strengthened model, runtime-pack, and update downloads with size, source, version, and SHA-256 validation.

Changes

Major

• Replaced JSON metadata loading with a centralized a2m.core.config module and removed A2M/a2m/core/app_config.json.
• Updated the main window UX with a new always-on-top pin toggle and responsive/resizable layout behavior.

Minor

• Migrated core/service/UI imports from a2m.core.constants to a2m.core.config; constants.py now acts as a compatibility shim.
• Updated updater payload contracts and worker/controller plumbing to use setup-focused fields (setup_url, setup_sha256, setup_size).
• Improved pointer cursor behavior for additional interactive controls (QComboBox, item views).

Changes

Major

• Migrated runtime inference to ONNX Runtime.
• Switched model artifact to PianoModel.onnx from https://downloads.justagwas.com/a2m/PianoModel.onnx.
• Removed legacy PyTorch runtime flow and .pth runtime fallback paths.
• CPU runtime is now the default shipped mode.
• Added optional in-app GPU runtime pack installation for CUDA (a2m-onnx-cuda.zip) and DirectML (a2m-onnx-dml.zip).
• Added a Transcription Engine selector in settings:
  • Legacy v1.0.0
  • Modern v2.0.0
• Legacy is the default engine; Modern keeps dedicated tuning behavior.

Minor

• GPU runtime packs are installed per-user under %LOCALAPPDATA%\A2M\runtime_packs\{cuda|dml}.
• App config now writes to %LOCALAPPDATA%\A2M\a2m_config.json.
• Added stricter GPU runtime validation to avoid accepting partial/corrupt installs.
• Fixed ONNX runtime probe stability issues related to repeated PATH/DLL handling.
• Unified runtime artifact/provider detection across runtime services to reduce mismatch edge cases.
• Unified GPU validation logic across settings status, GPU toggle, provider switching, and conversion startup.
• Added explicit GPU status state for unvalidated runtime (Validation pending) to avoid false "GPU active" messaging.
• Startup now surfaces ONNX/GPU validation progress in the main UI and clears the validation prompt automatically when checks finish.
• Improved fallback handling so ONNX-runtime-missing flows are handled separately from CUDA dependency failures.
• CUDA install guidance/prompts are now shown only for CUDA-specific failure reasons.
• cuDNN install flow is now asynchronous (non-blocking UI) with progress + cancel handling.
• Fixed frame trimming logic for ONNX output deframing.
• Continued MIDI post-processing cleanup for short/overlapping note events.
• GPU mode now prompts users to install required runtime components when unavailable.
• Provider selection (Auto, CUDA, DirectML) now respects availability state.
• Refined settings/runtime status behavior and related stale messages.
• Modern engine feature toggles include:
  • Adaptive thresholds per file
  • Input normalization / denoise
  • Smarter overlap stitching
  • Smart auto calibration
• Modern controls now hide/show contextually based on selected engine and calibration mode.
• Added/updated ONNX/GPU runtime-related config fields.
