Drive settings

C2 Pointers supported

Drive is capable of reporting C2 data errors.

CD-DA stream is accurate

Drive is able to provide accurate audio stream and can report synchronization errors. "Accurate CD-DA Stream"

Cache size

Cache memory size of the drive. Drive uses cache to speed up read and write operations.

Enable Error Detection

Detect and report Read, Synchronization, and Data Errors that may occur during the CD Ripping.

Method

Both methods 'C2 #1' and 'C2 #2' work exactly the same way, and use the same error detection scheme.

Default is 'C2 #1' and it works for almost all of the drives.

If the selected read method does not work properly (i.e. there are read errors, or the CD ripping is very slow), then the method needs to be switched to other one.

Enable drive spin-up

Spin-up the disc to full speed before starting the actual CD ripping operation. Specify the number of seconds to spin-up before starting the CD ripping.

Use sample offset correction

Because audio CDs do not contain information for the exact start points of the audio tracks on the media; drive is not able to read exactly from the expected position of the audio data, and will add an offset to the requested position of the audio data. Audio data is shifted the number of samples of the offset. Sample offset usually varies between 0-1000 samples with different drives. One sample is 1/44100 second (22.676 µs). For example: 500 samples is 500/44100 seconds which is 11.3 milliseconds. Because offsets are such small differences, you do not need to enable sample offset correction for better sound quality - simply because you do not hear the small differences when you listen to the music. The same behavior will occur with regular home/car CD-players also.

Sample offsets are useful when you want to compare the CRCs of the rips with different drives. When the correct sample offset is set for two drives, you can compare the CRCs of the rips between these drives. Same CRCs mean that both drives made identical copies of the audio tracks.

Get offset

Retrieves the sample offset for your drive from AccurateCDDA database.

Verify Audio

Do 2-pass CRC verification, calculate CRCs sector-by-sector and report CRC errors with accurate position information.

Defeats the drive cache, so that the audio data is read direct from the disc, not from the drive's read cache.

Audio tracks are read twice and CRCs are calculated for both reads. CRCs can be compared for the consistency of the audio data. Identical CRCs means that the rip has been done twice with identical results which means that the audio data is perfect and identical to the original audio data on the CD.

Verify Data

Data tracks are read twice and CRCs are calculated for both reads. CRCs can be compared for the consistency of the data. Identical CRCs means that the rip has been done twice with identical results which basically means that the data is perfect and identical to the original data on the disc.
