Syntax

public abstract class AudioMediaBuffer : IDisposable

Constructors

AudioMediaBuffer()

Declaration

protected AudioMediaBuffer()

Properties

ActiveSpeakers

Current active speakers in the conference.

Declaration

public uint[] ActiveSpeakers { get; protected set; }

Property Value

Type	Description
UInt32[]

Remarks

The value is the IDs (MediaSourceIds) of the audio source of the active speakers in the conference and does not include bot's own MediaSourceId. If there is no active speaker, or there is just silence in the conference, the value is an empty array.

AudioFormat

The audio format.

Declaration

public AudioFormat AudioFormat { get; protected set; }

Property Value

Type	Description
AudioFormat

Data

Pointer to the unmanaged media buffer.

Declaration

public IntPtr Data { get; protected set; }

Property Value

Type	Description
IntPtr

IsSilence

Indicates if the received audio media buffer contains only silence. This property is set automatically for received audio buffers. When sending buffers via the Send method, this property is unused.

Declaration

public bool IsSilence { get; protected set; }

Property Value

Type	Description
Boolean

Length

The length in bytes of the data in the media buffer.

Declaration

public long Length { get; protected set; }

Property Value

Type	Description
Int64

Timestamp

Timestamp of when the media content was received by the bot, or if the bot is sending media, the timestamp of when the media was sourced. It is in 100-ns units. When sourcing media buffers, this property should be set using the value from the MediaPlatform.GetCurrentTimestamp() API.

Declaration

public long Timestamp { get; protected set; }

Property Value

Type	Description
Int64

UnmixedAudioBuffers

Contains the list of received unmixed audio buffers (up to four at a time).

Declaration

public UnmixedAudioBuffer[] UnmixedAudioBuffers { get; protected set; }

Property Value

Type	Description
UnmixedAudioBuffer[]

Remarks

This is useful for advanced meeting scenarios, such as being able to receive separate audio buffers for individual speakers. This value is set only on the receive side when the AudioSocketSetting.ReceiveUnmixedMeetingAudio property is set to true. Creating unmixed audio buffers and sending it on the AudioSocket is not supported. This property is null when unmixed buffers are not requested.

Methods

Disposes the object.

Declaration

public void Dispose()

Dispose(Boolean)

Releases unmanaged resources held by the buffer object. Must be implemented in the derived class.

Declaration

protected abstract void Dispose(bool disposing)

Parameters
