Methods

domain

  • domain(domain: "timeoverview", channel?: ChannelNumber): TimeOverview

  • This method selects domain for visualization. This method is overloaded for type interface and type check.

    Parameters

    • domain: "timeoverview"

      This argument is one of 'timeoverview', 'time', 'fft'.

    • Optionalchannel: ChannelNumber

      This argument is channel number (Left: 0, Right: 1 ...).

    Returns TimeOverview

    Return value is instance of selected Visualizer class.

  • domain(domain: "time", channel?: ChannelNumber): Time

  • This method selects domain for visualization. This method is overloaded for type interface and type check.

    Parameters

    • domain: "time"

      This argument is one of 'timeoverview', 'time', 'fft'.

    • Optionalchannel: ChannelNumber

      This argument is channel number (Left: 0, Right: 1 ...).

    Returns Time

    Return value is instance of selected Visualizer class.

  • domain(domain: "fft", channel?: ChannelNumber): FFT

  • This method selects domain for visualization. This method is overloaded for type interface and type check.

    Parameters

    • domain: "fft"

      This argument is one of 'timeoverview', 'time', 'fft'.

    • Optionalchannel: ChannelNumber

      This argument is channel number (Left: 0, Right: 1 ...).

    Returns FFT

    Return value is instance of selected Visualizer class.

get

param

  • param(params: "fftSize"): number

  • This method gets or sets parameters for analyser. This method is overloaded for type interface and type check.

    Parameters

    • params: "fftSize"

      This argument is string if getter. Otherwise, setter.

    Returns number

    Return value is parameter for analyser if getter. Otherwise, return value is for method chain.

  • param(params: "frequencyBinCount"): number

  • This method gets or sets parameters for analyser. This method is overloaded for type interface and type check.

    Parameters

    • params: "frequencyBinCount"

      This argument is string if getter. Otherwise, setter.

    Returns number

    Return value is parameter for analyser if getter. Otherwise, return value is for method chain.

  • param(params: "minDecibels"): number

  • This method gets or sets parameters for analyser. This method is overloaded for type interface and type check.

    Parameters

    • params: "minDecibels"

      This argument is string if getter. Otherwise, setter.

    Returns number

    Return value is parameter for analyser if getter. Otherwise, return value is for method chain.

  • param(params: "maxDecibels"): number

  • This method gets or sets parameters for analyser. This method is overloaded for type interface and type check.

    Parameters

    • params: "maxDecibels"

      This argument is string if getter. Otherwise, setter.

    Returns number

    Return value is parameter for analyser if getter. Otherwise, return value is for method chain.

  • param(params: "smoothingTimeConstant"): number

  • This method gets or sets parameters for analyser. This method is overloaded for type interface and type check.

    Parameters

    • params: "smoothingTimeConstant"

      This argument is string if getter. Otherwise, setter.

    Returns number

    Return value is parameter for analyser if getter. Otherwise, return value is for method chain.

  • param(params: AnalyserParams): Analyser

  • This method gets or sets parameters for analyser. This method is overloaded for type interface and type check.

    Parameters

    • params: AnalyserParams

      This argument is string if getter. Otherwise, setter.

    Returns Analyser

    Return value is parameter for analyser if getter. Otherwise, return value is for method chain.

start

  • start(domain: Domain, channel?: ChannelNumber, buffer?: AudioBuffer): Analyser

  • This method visualizes sound wave.

    Parameters

    • domain: Domain

      This argument is one of 'timeoverview', 'time', 'fft'.

    • Optionalchannel: ChannelNumber

      This argument is channel number (Left: 0, Right: 1 ...).

    • Optionalbuffer: AudioBuffer

      This argument is instance of AudioBuffer (If domain is 'timeoverview', this argument is required).

    Returns Analyser

    Return value is for method chain.
