Audio Analysis for Mixing
Audio analysis means measuring what's actually in your mix, not what you think is in it. Loudness, dynamics, frequency content, phase relationships, stereo width: all of these have objective measurements. After a long session your ears lie to you. The numbers don't. Phantom provides all of them inside Claude. This page maps out each analysis domain and links to the tool docs.
Loudness and Dynamics
Loudness analysis tells you whether your mix hits streaming targets and how much dynamic range you have left. Dynamics analysis shows how compressed the material is. Useful when you're trying to figure out if your limiter is working too hard or why the transients went soft.
- analyze_loudness:Integrated LUFS, true peak, LRA, and streaming platform compliance check
- analyze_dynamics:Crest factor, dynamic range, compression assessment, transient detection
Spectral Analysis
Spectral analysis shows you where the frequency energy actually sits and where the holes are. Masking analysis takes it further: it tells you which elements are fighting over the same ranges. That overlap is usually the reason a mix sounds muddy even after you've EQ'd everything individually.
- analyze_spectrum:Full-band frequency analysis, spectral balance across the mix
- analyze_masking:Frequency masking analysis on a stereo mix or single stem
- multi_stem_masking:Cross-masking analysis across multiple stems simultaneously
Stereo and Phase
Stereo and phase measurements tell you how the mix translates to mono. Phase issues that are invisible in stereo can wreck you on phones, club systems, and broadcast. Knowing the correlation number before mastering is a lot better than finding out after.
- analyze_stereo:Stereo width, mid/side balance, phase correlation coefficient
- analyze_phase:Phase analysis for a single track or stem
- compare_phase:Phase comparison between two audio files (useful for parallel processing and stem alignment)
Problem Detection
Problem detection runs a batch of checks and flags what needs attention: clipping, low-end buildup, phase problems, stereo imbalance. The full diagnostic combines all of them and returns a prioritized list. It's the fastest way to find out what's broken before you send something to mastering.
- detect_problems:Automated problem detection across loudness, phase, clipping, and dynamics
- full_diagnostic:Complete analysis in one command: loudness, dynamics, spectrum, stereo, phase, and problems
- batch_diagnostic:Run full diagnostics across multiple files at once
Reference Comparison
Reference comparison measures how your mix stacks up against a reference track or genre profile. "Does this sound right?" doesn't tell you much. "This is 3.2 LUFS louder than the reference and the low end is 4dB heavier" does.
- compare_to_reference:A/B loudness and spectral comparison between your mix and a reference track
- compare_to_profile:Compare your mix against a genre-specific loudness and dynamic range profile
