Detailed Description
AudioData is delivered for every frame of audio decoded from a media stream.
The audio is decompressed into PCM format having been compressed during transmission.
The audio is compressed using the Speex audio encoder and the Mode and Quality properties give Speex specific information about the nature of the audio compression in use.
Note that the when two channels of audio are being transmitted they are coded independently
Availability
Available in version 6.0 of Decoder SDK. Requires a server version greater than 6.0

Member Function Documentation
| DB_EDGEVIS_SDK byte_array EdgeVisDecoderSDK::AudioData::GetBuffer | ( | ) | const |
Gets audio samples for a frame.
Information format of the audio samples is given by the properties. If the audio is comprised of two channels then the samples are interleaved alternating left and right values.
- Returns
- The audio buffer as a byte_array.
| DB_EDGEVIS_SDK short_array EdgeVisDecoderSDK::AudioData::GetBufferShort | ( | ) | const |
Gets audio samples for a frame.
information format of the audio samples is given by the properties. If the audio is comprised of two channels then the samples are interleaved alternating left and right values.
- Returns
- The audio buffer as an array of signed short values.
| DB_EDGEVIS_SDK int32_t EdgeVisDecoderSDK::AudioData::GetSize | ( | ) | const |
Gets the size of the audio buffer.
- Returns
- The size, in bytes, of the audio buffer.
| DB_EDGEVIS_SDK int64_t EdgeVisDecoderSDK::AudioData::GetTimeStamp | ( | ) | const |
Gets the timestamp of the audio data.
- Returns
- The timestamp in milliseconds since 1/1/1970
| DB_EDGEVIS_SDK AudioConfig EdgeVisDecoderSDK::AudioData::GetConfig | ( | ) | const |
Gets the audio configuration information.
