Class MFCC

Mel-frequency cepstral coefficients.

Example

var mfccBuilder = MachineLearning.createMFCCBuilder();

var mfcc = mfccBuilder.setFrameSize(1920)
    .setHopSize(480)
    .setFFTSize(2048)
    .setNumMFCC(13)
    .setNumMel(13)
    .setLifter(0)
    .setMinFreq(0.0)
    .setMaxFreq(8000.0)
    .setSampleRate(16000).build();

Max tensor size.

Methods

getTypeName

isOfType

  • isOfType(type: string): boolean

    Returns true if the object matches or derives from the passed in type.

    Parameters

    • type: string

    Returns boolean

isSame

  • isSame(other: ScriptObject): boolean

    Returns true if this object is the same as other. Useful for checking if two references point to the same thing.

    Parameters

    Returns boolean

process

  • process(inTensor: Float32Array, inShape: vec3, outTensor: Float32Array): vec3

    Process in tensor with shape, write result to the outTensor, and returns the shape of outTensor.

    Parameters

    • inTensor: Float32Array
    • inShape: vec3
    • outTensor: Float32Array

    Returns vec3
