v7.1 Highlights

AcoustID support!

Use acoustID to replace the need for ACRcloud or combine both for an expansive catalog of music identification

End-to-End Workflow (Now Includes Recording)

Built-in system audio recording on Windows/macOS
Record, split, identify, review, and export in one tool
Makes MixSplitR a full capture-to-library workflow

Album Search + Normalization + Deep Scan

Album search toggle for release-focused matching/grouping
Artist normalization toggle for cleaner folders and filenames
- Collab/feat credits can be moved into title metadata
Auto Deep Scan mode for recursive subfolder discovery

Session History (Beta) Expansion

Session-first history workflow
Compare two sessions
Reorganize files from session metadata
Rollback with dry-run preview before delete
Import/export session records (.json) (drag-drop path supported)
Safe session apply to a target folder (no overwrite/no delete)
Delete session records with safety checks (history JSON only)
Rollback apply writes a new rollback session record for audit trail

Auditable Processing with Rollback

Session manifests capture processing details and outputs
History is designed for audit/review, not just quick reruns
Rollback includes preview-first safety before apply

Unsaved Preview Workflow

Finish Unsaved Preview from main menu
Clear Unsaved Preview Data option
Exit flow that lets you keep or clear unsaved preview work

In-Tool Track Preview and Editing

Preview track audio directly in the editor
Edit track metadata before file creation
Convert unidentified tracks to identified inside the app
MusicBrainz search assist to label individual tracks quickly
Import tracklists/CUE data to speed up labeling
Supports simple tracklist formats (e.g., MM:SS Artist - Title, HH:MM:SS Artist - Title (Album))

Multi-Format Export + Splitter Input Support

Multi-file-type export options (lossless + lossy profiles)
Waveform splitter supports common audio formats and converts internally for waveform playback

Portable Startup Scan Mode

New first-run option and Settings toggle:
- Portable Startup Scan (ON/OFF)
ON: startup scans audio next to app/script
OFF: startup uses your Music folder

Expanded Identification Modes and Sources

ACRCloud + MusicBrainz
MusicBrainz only mode for users who do not want paid API dependency
AcoustID support for MusicBrainz fingerprint matching
Shazam integration as an additional identification path
Dual Mode (runs multiple backends, picks best-confidence result)
Better coverage for difficult/underground tracks via multi-source enrichment

Fingerprint Accuracy Tuning

Configurable fingerprint sample window (8-45s, default 12s)
Applied to ACRCloud, Dual mode, and Shazam sampling paths
Lets you trade speed for better hit rate on difficult tracks

Improved Settings and Directory Controls

Album search toggle
Artist normalization toggle (collab credits moved to title)
Auto deep scan toggle
Portable startup scan toggle
Directory settings for:
- Output folder
- Recording folder
- Session History folder

One-Click / Direct Mode Improvements

Direct Mode now asks for output format before export (instead of silently forcing one format)
Selected output format is saved in session/manifest config snapshots

Better Data Handling and Storage Defaults

Config, cache, and session data are kept in a dedicated app-data folder
- Windows: %APPDATA%\\MixSplitR
- macOS: ~/Library/Application Support/MixSplitR
- Linux: ~/.local/share/MixSplitR
Music output defaults to a nested library under your Music folder:
- ~/Music/MixSplitR Library (or platform equivalent)

Core Features

Automatic split detection for mixes with silence gaps
Manual visual splitter for seamless DJ mixes
Assisted splitting (auto-detect + manual review)

- Audio preview
- Manual metadata correction
- Convert unidentified tracks to identified
- MusicBrainz text-search assist for difficult IDs

Preview/Apply workflow:
- Full Preview (cached chunks + playback/edit support)
- Light Preview (lower disk usage, re-splits on apply)
Metadata enrichment from multiple sources (MusicBrainz, iTunes, Deezer, Last.fm)
Configurable fingerprint sample size (8-45s) for identification tuning
Local BPM detection fallback via librosa
Artist-folder organization and metadata tagging
System audio recording flow (Windows/macOS)
Large-file streaming mode (FFmpeg-based) for memory-heavy files

Review in Track Editor, then apply.
Use Session History (Beta) for compare/restore/import/export/delete workflows.
