Interface MFCCBuilder

Builder class for the MFCC (Mel Frequency Cepstral Co-efficients).

Example

var mfccBuilder = MachineLearning.createMFCCBuilder();
interface MFCCBuilder {
    build(): MFCC;
    getTypeName(): string;
    isOfType(type: string): boolean;
    isSame(other: ScriptObject): boolean;
    setFFTSize(fftSize: number): MFCCBuilder;
    setFrameSize(frameSize: number): MFCCBuilder;
    setHopSize(hopSize: number): MFCCBuilder;
    setLifter(lifter: number): MFCCBuilder;
    setMaxFreq(maxFreq: number): MFCCBuilder;
    setMinFreq(minFreq: number): MFCCBuilder;
    setNumMel(numMel: number): MFCCBuilder;
    setNumMFCC(numMFCC: number): MFCCBuilder;
    setSampleRate(sampleRate: number): MFCCBuilder;
}

Methods

build

  • build(): MFCC

  • Create a new MFCC object.

    Returns MFCC

getTypeName

isOfType

  • isOfType(type): boolean

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

    Parameters

    • type: string

    Returns boolean

isSame

  • isSame(other): 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

setFFTSize

  • setFFTSize(fftSize): MFCCBuilder

  • Sets the length of the FFT window.

    Parameters

    • fftSize: number

    Returns MFCCBuilder

setFrameSize

  • setFrameSize(frameSize): MFCCBuilder

  • Length of the window, the window will be the length of frameSize and then padded with zeros to mach FFTSize.

    Parameters

    • frameSize: number

    Returns MFCCBuilder

setHopSize

  • setHopSize(hopSize): MFCCBuilder

  • Sets the number of samples between successive FFT segments.

    Parameters

    • hopSize: number

    Returns MFCCBuilder

setLifter

  • setLifter(lifter): MFCCBuilder

  • If lifter > 0, apply liftering to the MFCCs.

    Parameters

    • lifter: number

    Returns MFCCBuilder

setMaxFreq

setMinFreq

setNumMel

setNumMFCC

  • setNumMFCC(numMFCC): MFCCBuilder

  • Sets the number of MFCCs to return.

    Parameters

    • numMFCC: number

    Returns MFCCBuilder

setSampleRate

  • setSampleRate(sampleRate): MFCCBuilder

  • Sets the number of samples per second.

    Parameters

    • sampleRate: number

    Returns MFCCBuilder
