Methods

build

  • build(): MFCC

    Create a new MFCC object.

    Returns MFCC

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

setFFTSize

  • setFFTSize(fftSize: number): MFCCBuilder

    Sets the length of the FFT window.

    Parameters

    • fftSize: number

    Returns MFCCBuilder

setFrameSize

  • setFrameSize(frameSize: number): 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: number): MFCCBuilder

    Sets the number of samples between successive FFT segments.

    Parameters

    • hopSize: number

    Returns MFCCBuilder

setLifter

  • setLifter(lifter: number): MFCCBuilder

    If lifter > 0, apply liftering to the MFCCs.

    Parameters

    • lifter: number

    Returns MFCCBuilder

setMaxFreq

setMinFreq

setNumMel

setNumMFCC

  • setNumMFCC(numMFCC: number): MFCCBuilder

    Sets the number of MFCCs to return.

    Parameters

    • numMFCC: number

    Returns MFCCBuilder

setSampleRate

  • setSampleRate(sampleRate: number): MFCCBuilder

    Sets the number of samples per second.

    Parameters

    • sampleRate: number

    Returns MFCCBuilder
