| TMdaRawPackage::iThis | |
The settings for audio data played through the media server.
These can be the settings for an audio clip, for streamed audio data, or can be the capabilities of the sound device. The sample rate and number of channels apply to the audio sample, the maximum volume applies to the output device and the volume setting can apply to either, depending on the device. An object of this class is a public data member of class CMdaAudioType and also can be passed to CMdaAudioOutputStream::Open().

| TInt | iCaps |
Specifies the capabilities of the audio sample. Its value is a combination of the flags contained in the TAudioCaps enum.
| TInt | iFlags |
The flags. Its value can be either of the flags contained in the TAudioFlags enum.
| TInt | iVolume |
The volume. Whether this applies to the audio device or to the audio sample is device-dependent.
Audio capabilities, which include the sample rate and number of channels. The iCaps member is a combination of these flags.

| ERoutingControl | 0x08000000 |
Routing related |
| ERealTime | 0x10000000 |
True if data flow is synchronised with real time (e.g. stream) |
Mutually exclusive flags that specify whether audio data is sent to the local device (speakers) or the network (phone line) or both. The iFlags member uses these flags.
| Enumerator | Value | Description |
|---|---|---|
| ENoLocalRouting | 0x00000001 |
The sound data is only sent to the network. |
| ENoNetworkRouting | 0x00000002 |
The sound data is only sent to the local device. |
| TMdaAudioDataSettings | ( | ) | [inline] |
Default constructor. The member data is not initialised.
