Exact Audio Copy
Exact Audio Copy ( EAC often abbreviated ) is a freeware software, a CD ripper for reading (ribs) of audio CDs, a process which is also known as Digital Audio Extraction (DAE ). EAC is developed since the mid 1990s by André Wiethoff for Windows. Special emphasis is the exact as possible, ie error-free readout of the data in order to create identical copies may, in case of doubt at the expense of speed.
History of development
Wiethoff developed EAC, because he was dissatisfied with audio grave Bern available with how scratched audio CDs were treated. Neither they could read scratched media error free nor documented in the event of an error, the occurrence and timing so that the ripped audio data had to be tested fully by hearing test. EAC is developed as a native Windows program, but it was also used successfully with new versions of Wine on Linux.
In the so-called Secure Mode Ripping can be lossless with ( mostly older ) CD- ROM drives that show without EAC reading problems, with probability bordering on certainty the extent that the cause of the problem lies not with the respective CD, for example, by scratches, dirt or a copy. But even in such cases is increasing through the use of EAC, the probability to an acceptable error-free read-out result.
Repeatedly, bit by bit -wise reading of the CD incorrectly read points can be corrected or at least identified. The user receives error messages about reading problems and their position, even if the drive despite problems still reporting an error. The subjective audio quality is usually better than using conventional selection programs in such difficult locations. The messages when reading each audio track can be stored in a log file, thus defective areas can be documented and evaluated before further processing.
The files thus obtained are initially stored as a RIFF WAVE files and can then trace amounts ( ie during the remaining tracks are read ) are converted using any audio codec from EAC out. Since you can have multiple compression processes can run simultaneously, also multi-core processors can take advantage of sense. In addition, the program includes a simple CD writing functionality ( though with the possibility of sample offset correction), so that even CD copies can be created using only EAC.
Additional features include:
- Possibility of offset correction
- Using the C2 error information of the optical drive (only useful if the drive dominates this correctly )
- Creation of CRC checksums of the ripped audio material; with a free extension called AccurateRip, the user can compare the checksum calculated a particular piece of music with the other users.
- Possibility of auto detection of DAE conducive or hindering characteristics of the optical drive with the aid of reference CDs.
- Query the freedb database ( submission of titles and artist ), but NET Framework is the. Required
According to the website is EAC freeware ( donationware ) as long as it is not used for business purposes. But the author would be on voluntary donations.
Due to the wide range of functions and not reduced to simple functions surface beginners is the first access bit more difficult. Therefore, the Internet different advice pages available with detailed instructions for ripping CDs.
