Phantom’s tools are organized by workflow stage. Most tools work on audio files; profile tools read reference data, and read_live_metrics reads a snapshot from a separate producer. Processing and separation tools write output files.
Pre-mix Analysis
Understand your material before touching faders.
| Tool | What it measures |
|---|---|
| analyze_spectrum | Frequency balance – centroid, rolloff, contrast, flatness, dissonance |
| analyze_loudness | Integrated LUFS, true peak, loudness range, short-term and momentary |
| analyze_dynamics | RMS, peak, crest factor, dynamic range, complexity |
| analyze_phase | Phase coherence per frequency band and polarity |
| detect_problems | Clipping, DC offset, ISP, hum, sibilance, mud, harshness, resonances |
| full_diagnostic | Comprehensive single-file analysis (runs all pre-mix tools) |
| batch_diagnostic | Analysis across up to 50 files in one call |
During Mixing
Make informed decisions while mixing.
| Tool | What it measures |
|---|---|
| analyze_stereo | Stereo width, balance, mid/side ratio, correlation, panorama |
| analyze_masking | Per-octave frequency overlap between two stems |
| multi_stem_masking | Frequency collision severity across multiple stems |
| compare_phase | Phase relationship comparison between two sources |
Mastering Prep
Compare and match to targets.
| Tool | What it measures |
|---|---|
| compare_to_profile | Compare against genre target specs (pop, rock, hip-hop, EDM, etc.) |
| list_profiles | List every available genre profile name |
| load_profile | Load a genre profile’s full target data as JSON |
| compare_to_reference | A/B spectral and loudness analysis against a reference track |
| match_to_reference | Process audio against a reference with Matchering |
Remediation and Processing
Fix problems and apply corrections. These tools require the processing extra: uv tool install "phantom-audio[processing]" --python 3.13 --force.
| Tool | What it does |
|---|---|
| fix_audio | Auto-fix detected audio problems with corrective EQ and filtering |
| apply_processing | Apply custom audio processing chains to files |
Utilities
| Tool | What it does |
|---|---|
| separate_stems | Separate audio into vocals, drums, bass, and instruments via Demucs |
| read_live_metrics | Read the Phantom Studio plugin’s live meter snapshot |
Pro tip
You don’t need to call tools by name. Describe what you want to know – “Is my mix too loud?”, “Are the vocals masking the guitar?”, “Compare this to a professional reference” – and your AI assistant will pick the right tool.
