Namespace: Un4seen.Bass.AddOn.Cd
Assembly: Bass.Net (in Bass.Net.dll) Version: 2.4.12.0
Syntax

[DllImportAttribute("basscd.dll", CharSet = CharSet.Auto)]
public static bool BASS_CD_Analog_Play(
	int drive,
	int track,
	int pos
)

Parameters

drive
Type: SystemInt32
The drive... 0 = the first drive.
track
Type: SystemInt32
The track... 0 = the first track.
pos
Type: SystemInt32
Position (in frames) to start playback from. There are 75 frames per second.

Return Value

Type: Boolean
If successful, is returned, else is returned. Use BASS_ErrorGetCode to get the error code.
Remarks

Some old CD drives may not be able to digitally extract audio data (or not quickly enough to sustain playback), so that it's not possible to use BASS_CD_StreamCreate(Int32, Int32, BASSFlag) to stream CD tracks. This is where the analog playback option can come in handy.

In analog playback, the sound bypasses BASS - it goes directly from the CD drive to the soundcard (assuming the drive is cabled up to the soundcard). This means that BASS output does not need to be initialized to use analog playback. It also means it's not possible to apply any DSP/FX to the sound, and nor is it possible to visualise it (unless you record the sound from the soundcard).

Analog playback is not possible while digital streaming is in progress - the streaming will kill the analog playback. So if you wish to switch from digital to analog playback, you should first free the stream using BASS_StreamFree(Int32).

ERROR CODEDescription

Examples

Play track 3 on drive 0, starting at the 10 second point:
VB
Dim ok As Boolean = BassCd.BASS_CD_Analog_Play(0, 3, 10 * 75)
bool ok = BassCd.BASS_CD_Analog_Play(0, 3, 10 * 75);
