Struct ChunkerConfig 

pub struct ChunkerConfig {
    pub target_duration: Duration,
    pub max_duration: Duration,
    pub duration_tolerance: Duration,
    pub min_duration: Duration,
    pub overlap_duration: Duration,
}

Configuration for the audio chunker.

Controls how audio is segmented into processing chunks.

Fields

target_duration: Duration

Target duration for each chunk (default: 500ms).

Chunks will be approximately this duration, but may vary by up to duration_tolerance to align with speech boundaries.

max_duration: Duration

Maximum allowed chunk duration before forced split (default: 600ms).

Long speech segments exceeding this duration will be split into multiple chunks to maintain streaming latency guarantees.

duration_tolerance: Duration

Tolerance for chunk duration variance (default: 100ms).

Chunks may be target_duration ± duration_tolerance to better align with natural speech boundaries from VAD.

min_duration: Duration

Minimum chunk duration to emit (default: 100ms).

Segments shorter than this are buffered or merged with adjacent chunks to avoid inefficient processing of tiny fragments.

overlap_duration: Duration

Duration of overlap between adjacent chunks (default: 50ms).

Preserves acoustic context across chunk boundaries. Must be in range 20-80ms. Overlaps are stored in ProcessedChunk::overlap_prev and ProcessedChunk::overlap_next.

Implementations

impl ChunkerConfig

pub fn new( target_duration: Duration, max_duration: Duration, duration_tolerance: Duration, min_duration: Duration, overlap_duration: Duration, ) -> Result<Self>

Create a new chunker configuration with validation.

Errors

Returns Error::InvalidInput if:

• target_duration is zero or exceeds 5 seconds
• max_duration is less than target_duration
• min_duration exceeds target_duration
• overlap_duration is outside range 20-80ms

pub fn streaming() -> Self

Create a configuration optimized for real-time streaming (smaller chunks).

pub fn batch() -> Self

Create a configuration optimized for batch processing (larger chunks).
