}

Analysis confidence scores

Fields

bpm_confidence: f32

BPM confidence (0.0-1.0)

Based on:

• Method agreement (autocorrelation + comb filterbank)
• Peak prominence in period estimation
• Octave error handling

key_confidence: f32

Key confidence (0.0-1.0)

Based on:

• Template matching score difference
• Key clarity (tonal strength)
• Chroma vector quality

grid_stability: f32

Grid stability (0.0-1.0)

Based on:

• Beat grid consistency (coefficient of variation)
• Tempo variation detection
• Downbeat alignment

overall_confidence: f32

Overall confidence (weighted average)

Weighted combination of BPM, key, and grid stability:

• BPM: 40% weight
• Key: 30% weight
• Grid: 30% weight

flags: Vec<AnalysisFlag>

Confidence flags indicating specific issues

Implementations

impl AnalysisConfidence

pub fn is_high_confidence(&self) -> bool

Check if overall confidence is high (>= 0.7)

Returns

true if overall confidence is high, false otherwise

pub fn is_low_confidence(&self) -> bool

Check if overall confidence is low (< 0.5)

Returns

true if overall confidence is low, false otherwise

pub fn is_medium_confidence(&self) -> bool

Check if overall confidence is medium (0.5-0.7)

Returns

true if overall confidence is medium, false otherwise

pub fn confidence_level(&self) -> &'static str

Get a human-readable confidence level description

Returns

String describing the confidence level: “High”, “Medium”, or “Low”
