I am archiving my collection of over 1,000 CDs. Itís a big job, and I want to get it right so I donít have to repeat it. I already started to rip CDs using iTunes and Roxio, but I noticed quite a few songs had pops, crackles, and/or distortion. At first I thought it was a problem with my CD reader, and I went out and purchased a lens cleaning disc. When that didnít solve the problem, I did more research online and realized the problem might be with the programs I was using. That is how I cam across EAC, which I really love but find a tad confusing. So, I have a few questions.

My goal is to back-up every CD in two formats: 1) WAV files to store on an external hard drive as a true archive, and 2) MP3 files to use for iTunes and portable MP3 players. Here are my questions:

1. Is it possible to save in both MP3 and WAV files while only reading the disc once? At this point, I am reading it once for the WAV files and a second time for the MP3 files. I tried just reading it once and saving as WAV files and then converting to MP3s; however, when I did that, none of the info regarding artist, track number, etc. were saved and I had to manually edit the info for use in ITunes and other players. I already have two profiles save in EAC Ė one for WAV and one for MP3. In each case, I have file naming set to save the files in folders under the artist name, with a subfolder for the artist name.

2. Regarding compression settings, I am using the latest version of LAME (I think it is 3.99.5). I would be happy with VBR and a minimum bit rate of 256 kbps, but I found it simpler to just go with 320 kbps CBR. I am not too worried about the difference in file size. I am not sure if I have the correct settings or if I could reduce the number of additional commands. Here are the additional command-line options I have entered for External Compression:

-b 320 %islow%-V 5%islow%%ishigh%-V 2%ishigh% --vbr-new %source% %dest%

And here is a screenshot of my External Compression tab:



3. Does anybody know the easier way to import the ripped MP3 tracks to iTunes? At this point, I am ripping straight to the iTunes folder, with a folder for artist and subfolder for album. After the files are ripped, I go into iTunes and add the folder to the library.

4. In terms of playback, is one player better than another? Specifically, is one player better than iTunes for playback? I also have used WinAmp. For my home stereo, I can simply play the WAV files stored on my external hard drive, but I use an iPod for traveling and the car.

Sorry for all the questions on my first post. If it would be better, I can break them down to separate posts. I am most concerned only with Questions 1 and 2 above.

I had a feeling that the additional commands were useless or inappropriate. I copied them from somehwere and added the -b 320 because it was ripping at a much lower bit rate. What would be the right string of commands for either 320 or 256 VBR?

Here we see demonstrated the importance of knowing what an option does before you activate it. wink.gif “much lower” than what? What did you expect? What type of material were you compressing? As Aleron Ives has said, there’s not actually any such thing as “320 or 256 VBR”, so expecting to see either of those figures as a mean bitrate will only lead to disappointment! But again, it all depends upon what you are compressing. Generally, you can trust LAME to do its job efficiently: compressing with an appropriate probability of perceptual transparency determined by your chosen numerical setting and using only as many bits as it needs for that.
