Member Function Documentation

virtual iSoundData* Clone ( ) const

pure virtual

Clone the sound data.

Remarks: This is necessary for streaming as streamed data need separate read pointers.

virtual eSoundFormat GetFormat ( ) const

pure virtual

Get the sound's format bits. {Property}.

virtual tU32 GetFrequency ( ) const

pure virtual

Get the sound frequency in hertz. {Property}.

pure virtual

Read a chunk of the specified size.

Parameters

aptrOut	is the buffer where to output the data.
anSize	is the number of bytes to read.

virtual void Reset ( )

pure virtual

Reset data stream to the begining.

virtual tU32 GetLength ( ) const

pure virtual

Get the sound length in frames. {Property}.
