Drive settings

C2 Pointers supported

Drive is capable of providing C2 error pointers to detect audio data errors. This information is used to detect ripping 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

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

Enable Error Detection

Detect and report data errors.

C2 error pointers and Accurate CD-DA will be used for error detection if they're available. Otherwise, software based error detection (much slower) will be used.

Error detection mode calculates CRC checksum for every track and for the complete CD. CRCs can be used to compare consistency of the different rips.

Compatibility mode

Compatibility mode can be enabled for the drives that support C2 error pointers, but return incorrect data errors, distorted audio, or read error in normal error detection mode.

Compatibility mode can use C2 pointers with a drive that doesn't properly support the C2 error pointers in normal error detection mode.

Compatibility mode also fixes the problem with some USB drives/drivers that can't transfer C2 error pointers in normal error detection mode.

Enable drive spin-up

Spin-up the disc to the full speed before starting to read from the disc. You can specify the number of seconds to spin-up before starting the reading.

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. But the 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

Queries the sample offset for your drive from AccurateCDDA(tm) database. If the database does not contain the sample offset for your drive, the database will use its internal algorithms to generate correct sample offset for your drive. The sample offset is then hardware-verified with Poikosoft staff. When the sample offset verification is finished the AccurateCDDA(tm) database is automatically updated with the new sample offset values for the drive. You can check back later if the sample offset for your drive has been added to the database.

Verify Audio

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 basically 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.
