## Detailed Description

The sound data is an interface to the container object controlling raw sound data.

After obtaining an iSndSysData interface (most likely by loading a sound file) at least one iSndSysStream must be obtained.

This interface is implemented at least once per Sound Element.

## Member Function Documentation

virtual iSndSysStream* iSndSysData::CreateStream | ( | csSndSysSoundFormat * | renderformat,
|  | int | mode3d |
| ) |  |  | `[pure virtual]`

This function should be called from the Renderer where a proper renderformat can be provided.

Creates a stream associated with this sound data positioned at the beginning of the sound data and initially paused if possible.

Remarks:
  Not intended to be called by an application.

virtual size_t iSndSysData::GetDataSize | ( |  | ) | `[pure virtual]`

Return the size of the data stored in bytes.

This is informational only and is not guaranteed to be a number usable for sound calculations. For example, an audio file compressed with variable rate compression may result in a situation where FILE_SIZE is not equal to FRAME_COUNT * FRAME_SIZE since FRAME_SIZE may vary throughout the audio data.

virtual const char* iSndSysData::GetDescription | ( |  | ) | `[pure virtual]`

Retrieve the description associated with this sound data.

virtual const csSndSysSoundFormat* iSndSysData::GetFormat | ( |  | ) | `[pure virtual]`

Get the format of the sound data.

virtual size_t iSndSysData::GetFrameCount | ( |  | ) | `[pure virtual]`

Get size of this sound in frames.

iSndSysData::SCF_INTERFACE | ( | iSndSysData | ,
|  | 0 | ,
|  | 2 | ,
|  | 0 |  |
| ) |  |  |

SCF2006 - See http://www.crystalspace3d.org/cseps/csep-0010.html.

virtual void iSndSysData::SetDescription | ( | const char * | pDescription | ) | `[pure virtual]`

Set an optional description to be associated with this sound data.
