There are two groups of audio data, compressed and uncompressed data. The compressed group could also be splitted to lossless and lossy compression. Lossless compression is like having uncompressed data, only that the file is only around 70% of the uncompressed size (Comparable to compression with WinZIP). To the group of lossy compression also belongs MP3, it is not possible to recreate the original audio file 100%, there are frequencies missing, etc. Now, MP3 is ONE lossy compression format, there are others like AAC, MP2, TAC, etc. The nice side on WAVs is that it could be wrapped on any compression for which an audio codec exists in Windows. So if you own the Fraunhofer Codec (or the LAME/Blade/Gogo DLL) you could produce MP3-WAVs. These are standard MP3 files, but having a small header preceeding the actual data telling the player what codec to use for playing/decompression. So these files could be played with any media player or any other sound tool. As the header does not matter on MP3 compression, you could even rename the MP3-WAVs from .wav to .mp3 without loosing playability by a MP3 player.

I’m trying to decode mp3 to wav’s but it keeps telling it can’t find codec. I know about the encoding dll issue, but this one has me stumped.
For decompression of MP3s the Fraunhofer MP3 Codec needed to be installed. It is sufficient to use the “advanced” Codec (not the “professional”). The advanced codec is part of windows. On older windows it could be installed by updating the media player… (Should be updated with the other codecs). The installed codec should then be listed in EACs codec list.

I want to compress audio tracks to MP3s, what do I need besides from EAC?
Remember that EAC does not supply a MP3 codec; you may use the LAME, Gogo or the BladeEnc DLL’s (or FAAC Dll for AAC compression) by copying them into the same directory where you copied EAC. Then you will be able to choose the installed DLLs in the compression option dialog box. Of course the quality of MP3 is based on the encoder and the bitrate you use. Beside the DLLs you could also specify external command line compressors that will be executed after an entire track was read (and not on-the-fly).

I have an Afreey drive and during extraction EAC sometimes hangs. What can I do?
It is still not known what causes this problem, there are Afreey users without any problems and some others have this problem. It is possible to continue the extraction by pressing the eject button on the drive. Try to play around a little bit with your options (DMA or deinstall busmaster drivers), probably it won’t help, but perhaps it does.

I have TEAC 532E-B and EAC says that the drive is capable of retreaving C2 error information. But EAC doesn’t report all errors in that mode!
It seems that C2 is not correctly implemented in some drives. To be on the safe side, you should turn off the C2 error correction.

If I rip a track in secure mode (Hitachi GD 2500, accurate stream, no cache, c2 correction) and during the rip process the correction indicator gets higlighted and then continues ripping. The EAC report indicates “No error” but when I hear the resulting wav file there is an error in it (a blank at the position where the correction indicator got highlighted)! The rest of the track is perfect of course. There is only this small blank.

I am getting Sync and Read errors occasionally, but EAC will still finish ripping, though with some “suspicious” positions. What to do now?
Clean the CD carefully and try again. If the errors don’t go away, listen to the suspicious positions and decide whether they are audible or not. You could also try to rip these tracks in burst mode, sometimes the reader could get better results on these bad sectors.

Ripping cd is saved as *.cgf and I don’t know why. I have used eac before and it worked perfect. Now it stuck saving as *.cgf.
Go to compression options and have a look if you selected “Do not write WAV header” and specified “cgf” below.

When using a CUE sheet generated by EAC in CDRWin, it tells, that the CUE sheet is not valid. When I have a look at the CUE sheet myself, I see that there are sometimes dozens of indecies that all have the same position. What can I do?
Try a different gap detection mode and if none removed that problem, you would have to edit these CUE sheets manually, removing all indecies bigger then 01 and indecies that have impossible possitions.

The last few audio CD’s I’ve copied using EAC all have the track position wrong by about 1 second. If I go to a particular track with my CD player, it will start the track about 1 second INTO the audio track. I have been using the “Copy Image And Create CUE Sheet” option for copying the CD’s. How can I avoid this problem in the future?
One of the biggest mistakes that could be made in 0.85beta (from 0.9beta3 on I prevented it automatically) is to have selected “Remove Leading And Trailing Silence”. If the image file contains silence at the beginning (e.g. 1 second) it will be removed and everything get moved by one second. So you should deactivate this option for 0.85b4. If this is not the problem, try a different gap detection mode and compare the generated CUE sheets manually.
