AudioAnalyzer

Afficher les obsolètes

AudioAnalyzer takes measurements from audio streams that are wired to it through Wire. It provides a single Input pin but does not produce any output streams.

Résumé

Propriétés

  • Lecture uniquement
    Non répliqué
    Lecture parallèle

    The loudest volume observed during the last audio buffer.

  • Lecture uniquement
    Non répliqué
    Lecture parallèle

    The root-mean-square average volume observed during the last audio buffer.

  • Lecture parallèle

    Enables usage of GetSpectrum.

Propriétés

PeakLevel

Lecture uniquement
Non répliqué
Lecture parallèle

The loudest volume observed during the last audio buffer. This property changes often and thus does not fire changed events.

RmsLevel

Lecture uniquement
Non répliqué
Lecture parallèle

The root-mean-square average volume observed during the last audio buffer. This property is generally more stable than PeakLevel but it may not capture momentary volume spikes.

SpectrumEnabled

Lecture parallèle

Enables usage of GetSpectrum(). If false, GetSpectrum() returns an empty array, but the CPU overhead of the AudioAnalyzer is dramatically reduced. This means that if you are only analyzing the volume of an audio stream, you can disable this property to improve performance.

Méthodes

GetConnectedWires

Instances

Returns an array of Wires that are connected to the specified pin. AudioAnalyzer has one "Input" pin.

Paramètres

pin: string

Instances

GetSpectrum

Returns the frequency spectrum of the last audio buffer, as an array of numbers. The elements of the array are root-mean-square volume levels, evenly spaced from 0 hertz to 24,000 hertz.
