Remarks
Starts ripping the given CD track of the given CD drive using the given Audio Compression Manager format.
A successful call to this method will cause the CallbackForRecordersEvents delegate to be invoked with the nEvent parameter set to the following values:
| • | EV_CD_RIPPING_START invoked once at the beginning |
| • | EV_CD_RIPPING_PERC invoked multiple times reporting the current advancement percentage inside the nDataLow3 parameter |
| • | EV_CD_RIPPING_SIZE invoked multiple times reporting the current size in bytes inside the combination of the nDataHigh3 and nDataLow3 parameters |
| • | EV_CD_RIPPING_STOP invoked as soon as the ripping session is completed |
For further details about the Windows Audio Compression Manager refer to the AudioComprMan class section.

Parameter
|
Description
|
|
|
nCdDriveIndex
|
Number representing the zero-based index of the involved CD drive.
Installed CD drives can be enumerated using the GetCdDrivesCount method and their friendly description can be retrieved through the GetCdDriveDesc method.
|
nTrackIndex
|
Number representing the one-based index of the CD audio track.
The total number of available audio tracks on the given CD can be obtained using the GetCdNumTracks method.
|
pWavData
|
Memory buffer containing the codec's format description based upon the WAVEFORMATEX structure, common to all waveform-audio formats and defined inside the Microsoft SDK as follows:
typedef struct {
WORD wFormatTag;
WORD nChannels;
DWORD nSamplesPerSec;
DWORD nAvgBytesPerSec;
WORD nBlockAlign;
WORD wBitsPerSample;
WORD cbSize;
} WAVEFORMATEX;
The cbSize member defines how many extra-bytes are appended to the end of the WAVEFORMATEX structure.
This buffer could be filled with custom contents or, in alternative, using the AudioCompressionManager.GetCodecFormatWavData method.
|
sizeWavData
|
Size in bytes of the memory buffer
|
strOutputPath
|
String representing the absolute pathname of the output file that will contain the song's ripped data. If this pathname should contain invalid characters, they would be automatically changed into an underscore '_' character.
|
