What is EAC?
EAC is “Exact Audio Copy”. It will help you to copy (extract) audio tracks, or even parts of them, to the harddisk. In newer versions it also includes some audio CD writing routines and a small audio editor.
Why should I use EAC, instead of AudioGrabber, WinDAC, etc.?
EAC features some special read modes, known as “Secure Modes”. Using these secure modes, every sector read will be doublechecked and reread or corrected if necessary. On many drives the extraction is not error free, thus these routines will make sure the track is read correctly.
Audio extraction is purely digital, how could unremarked errors occur?
The data transmission itself is purely digital and also the data stored on the CD. But the Red Book standard (standard for audio CDs) is very weak and only little error correction will be performed in the drive. So on bad CD-ROM drives it is possible that you receive erroneous results.
I want to install a newer version of EAC, do I have to uninstall the previous install first?
Unless otherwise indicated on a new release, for updates just extract the new exe file in your EAC dir. (I.e. overwrite the old exe) and you will retain the old settings. If you want to delete the old options nevertheless, just delete the key HKEY_CURRENT_USER\Software\AWSoftware\EAC .
How can I uninstall / remove EAC from my computer?
Uninstalling EAC is quite forward: Usually EAC lists itself under Start, All Programs in a folder called Exact Audio Copy. In that folder there is an entry called Uninstall. Click on this entry and follow the dialogs that are shown on the screen, confirm that you really want to uninstall EAC from your computer.
Where is the official homepage for EAC? Where can I download new versions?
It is at http://www.ExactAudioCopy.de/ There you will find a download page and a forum for persons who dislike the mailing list, but is not as good supported as the mailing list.
I downloaded the file EAC.ZIP from your homepage. Whenever I doubleclick on the file a text editor opens and shows garbage. How can I start EAC?
A ZIP file contains compressed files. This is easier for the transmission of several files. For decompression you need an UnZIP program like WinZIP.
I only own a very bad soundcard, or no soundcard at all… Does this matters?
No, your soundcard has nothing to do with ripping or burning cds. If you use digital extraction (which EAC does), you are not using the soundcard to create the wav, it’s read directly from the cd.
What is meant by “on-the-fly” ?
This means that one action is performed while (or intermixed with) another action. So e.g. if you extract and compress at once (and not extract first and compress afterwards), you could call it on-the-fly compression.
What are gaps (pre-track gaps)?
When playing an audio CD in a standalone player, often the time display will show up negative values before actually starting a track. This gap is usually used for seperate two different tracks. If jumping to a specific track, it will start with the actual music, only when running into a track the gap occurs.
Is it possible to extract audio digitally from a (Video) DVD?
Yes, but not using EAC and though it’s more manual work. For an unprotected DVD, the only hardware you will need is a DVD drive and a software to demultiplex the VOB files into the audio streams (usually compressed in AC3 or DTS). Then you need a programm to decompress these compressed files (a AC3 decompressor or a DTS decompressor).
Do you plan to release a Linux or MAC version of EAC?
Sorry, no Linux nor MAC version is planned at all. But it is reported that EAC runs in an emulation layer (WINE for Linux and Virtual PC Win 98 for MAC), so if you own this software have a try.
I use Windows NT/2000, but EAC seems to have problems to store the options or get any SCSI response.
Make sure you start EAC from an admin account, as some functions need a to access low level system routines, which are not accessable from user accounts. If you use the “Native SCSI Interface”, try the “ASPI Interface” instead, perhaps it will already help.
When trying to install EAC in Windows NT or Windows 2000, I get the following error message: “The DLL WNASPI32.DLL could not be found in the specified path” then a list of paths. I searched my hard drives and the named DLL does not exist on my machine. I found the DLL on the web and installed it into windows\system32\. Then I tried to re-install EAC and got the following error message: “The ASPI interface could not be initialized correctly! (Error E4h) (ASPI for Windows failed init)”. What now?
EAC needs a driver called “ASPI”, it is an SCSI driver, but works also with IDE CD-ROM drives (not a single file, but a complete package, so installing just the DLL won’t help). It is included in Win95/98, but not in Windows NT/2000. The newer versions of EAC should not absolute need ASPI anymore, but ASPI would be nevertheless the most stable. ASPI is available from different manufacturers (of SCSI interface cards), but it seems that the only working one with EAC is coming from Adaptec.
What is the difference between ASPI, ASAPI and Native drivers?
EAC communicates directly with the CD-ROM drives. For this EAC make use of several interfaces which do the low level work. You can choose the interface by your own in the EAC options (depending which interfaces are installed in your computer).
