}

Metadata tracking the complete conversion pipeline journey.

Captures information from all four conversion stages.

Fields

original_format: AudioFormat

Detected audio format (WAV, MP3, FLAC, etc.).

original_sample_rate: u32

Original sample rate in Hz before resampling.

original_channels: u8

Original number of channels before mixing.

original_bit_depth: Option<u16>

Original bit depth (if applicable, e.g., 16, 24 for PCM).

peak_before: f32

Peak amplitude in original audio before any processing.

peak_after: f32

Peak amplitude after complete conversion pipeline.

conversion_time_ms: f64

Total time spent in conversion pipeline (all 4 stages).

detection_time_ms: f64

Time spent in format detection stage.

decode_time_ms: f64

Time spent in decoding stage.

resample_time_ms: f64

Time spent in resampling stage.

mix_time_ms: f64

Time spent in channel mixing stage.

Implementations

impl ConversionMetadata

pub fn has_performance_issue(&self) -> bool

Check if any stage exceeded expected latency budget.

Expected budget breakdown for 3s clip:

• Detection: <1ms
• Decoding: <3ms
• Resampling: <5ms
• Mixing: <1ms
• Total: <10ms

pub fn peak_ratio(&self) -> f32

Calculate the peak amplitude reduction ratio from conversion.

Returns the ratio of final peak to original peak. Values:

• 1.0 = no amplitude change
• <1.0 = amplitude reduced (common with averaging/resampling)

• 1.0 = amplitude increased (rare, may indicate issue)

Trait Implementations

impl Clone for ConversionMetadata

fn clone(&self) -> ConversionMetadata

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for ConversionMetadata

impl Debug for ConversionMetadata

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for ConversionMetadata

fn eq(&self, other: &ConversionMetadata) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
