Description

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.

GetConnectedWires

Parameters (1)
pinstring
Returns (1)
Instances

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

GetSpectrum

Parameters (0)
No parameters.
Returns (1)
Array

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. If any of the analyzer's inputs come from an AudioDeviceInput, this method returns an empty array.

This function has a custom internal state. It may behave in a non-standard way.

PeakLevel

TypeDefault
float0

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

This property is not replicated. Its interface does not cross the network boundary.
This property is read-only. Its value can be read, but it cannot be modified.

RmsLevel

TypeDefault
float0

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.

This property is not replicated. Its interface does not cross the network boundary.
This property is read-only. Its value can be read, but it cannot be modified.

SpectrumEnabled

TypeDefault
booltrue

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.
