Easy CD-DA Extractor uses state-of-the-art AccurateCDDA(tm) CD-ripping engine

Drive capabilities

C2 Pointers supported
Drive is capable of providing C2 error pointers to detect audio data errors. Easy CD-DA Extractor will use this information to detect and repair errors.

 

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

 

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

AccurateCDDA reading mode

Normal
Fastest mode. Does not report any errors. Can be safely used for the CDs that are in pristine condition.

 

Mode #1 (simple error detection)
Reports data errors and synchronization errors based on the hardware status. For the drives that do not support hardware error reporting; basic error detection and software synchronization is enabled and errors are reported. Recommended mode for CDs that are in good condition.

 

Mode #2 (advanced error detection)
Turns on both hardware based and software based error detection. Recommended mode for CDs that may be in bad condition.

Mode #1 and Mode #2 will calculate CRC (checksum) for every track and for the complete CD. CRCs can be used to compare consistency of the rips.

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.

Use sample offset correction

Sample offset

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 from AccurateCDDA

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.
