Struct Spectrogram 

pub struct Spectrogram {
    pub data: Array3<f32>,
    pub segment_id: SegmentId,
    pub metadata: SpectrogramMetadata,
}

Input spectrogram for embedding generation.

Represents a mel spectrogram with shape [1, MEL_FRAMES, MEL_BINS] = [1, 500, 128].

Fields

data: Array3<f32>

The spectrogram data as a 3D array [batch, frames, bins]

segment_id: SegmentId

Associated segment ID

metadata: SpectrogramMetadata

Additional metadata

Implementations

impl Spectrogram

pub fn new( data: Array2<f32>, segment_id: SegmentId, ) -> Result<Self, EmbeddingError>

Create a new spectrogram from raw data.

Arguments

• data - 2D array of shape [MEL_FRAMES, MEL_BINS] (will be expanded to 3D)
• segment_id - ID of the source audio segment

Errors

Returns an error if the data dimensions are incorrect.

pub fn from_array3( data: Array3<f32>, segment_id: SegmentId, ) -> Result<Self, EmbeddingError>

Create from a 3D array directly

pub fn with_metadata(self, metadata: SpectrogramMetadata) -> Self

Set metadata for the spectrogram
