class AudioAnalyzerOVR : public AudioAnalyzerSource

Audio Analyzer OVR Source.

This class will be used to capture the audio in real time from a Oculus microphone, can playback the captured audio too

Public Functions

AudioAnalyzerOVR()

Constructor

~AudioAnalyzerOVR()

Destructor This will unload the audio too

AudioAnalyzerOVR(AudioAnalyzerOVR const &x) = delete

Disable copy constructor

Parameters:

x – —

void operator=(AudioAnalyzerOVR const &x) = delete

Disable copy assignment

Parameters:

x – —

bool initializeAudio(uint32 sampleRate, uint8 audioFormat, float audioBufferSeconds, bool initPlaybackDevice, uint32 periodSizeInFrames, uint32 periodSizeInMilliseconds, uint32 periods)

Initializes the capturer audio info and opens the audio capture (and player) device

Parameters:

  • sampleRate – Number of samples per second for the capture (and playback)

  • audioFormat – unsigned, signed, float indicator

  • audioBufferSeconds – Audio buffer size in seconds

  • initPlaybackDevice – Must initialize a playback device

  • periodSizeInFrames – Device audio buffer size in frames (power of 2), 0 to use default value

  • periodSizeInMilliseconds – Device audio buffer size in milliseconds, 0 to use default value

  • periods – Device audio buffer size multiplier

Returns:

The audio initilization result

void unloadAudio()

Closes the audio capturer (and player) device

void start(bool playback)

Starts the audio capturer (and player playback)

Parameters:

playback – Indicates if we want to playback the captured audio too

void stop()

Stops the audio capturer (and player playback)

bool isCapturing() const

Returns if the device is currently capturing audio

Returns:

Device is playing

virtual float getPlaybackProgress(float &bufferPosTime)

Returns the total capture duration and buffer postion time

Parameters:

bufferPosTime – [out] Current buffer position (seconds)

Returns:

float Duration in seconds

float getPlaybackProgress()

Returns the total capture duration

Returns:

float Duration in seconds

void setDefaultAudioDevices(const FString &capturerDeviceName, const FString &playerDeviceName)
