Chapter 7 Ripping and Encoding

Ripping is the process of extracting raw audio data from an audio CD-ROM. Encoding is the process of converting raw audio data into a format that uses less space. Exact Audio Copy may be abbreviated EAC.

7.1. What ripping software do you recommend?

The general consensus is that Exact Audio Copy is the the ripping program de jure.

7.2. How do I setup Exact Audio Copy?

This tutorial is the most popular, followed by this one.

7.3. Does iTunes rip as well as as Exact Audio Copy?

Probably not, but it is likely OK. iTunes is a music management program with a single checkbox entitled, “Use error correction when reading Audio Cds”. EAC's sole purpose is to obtain the most error-free rip possible.

7.4. Can I use iTunes?

If you have an iPod and you like the fact that iTunes provides one stop shopping for your ripping, encoding, tagging, and management needs, then go for it.

7.5. What are lossless codecs?

Free Lossless Audio Codec (FLAC) and Apple Lossless compress raw audio data without loss of information.

7.6. How effective is lossless codec compression?

The average compression ratio is approximately 55%. (reference)

7.7. Is there any sonic difference between a losslessly encoded file and a wav file?

No. Any differences you may hear are probably due to Replay Gain if you have enabled it.

7.8. What are the advantages of using a lossless codec instead of wav files?

You will save disk space.

You will save network bandwidth.

Your backups will take less time.

7.9. Which is better: FLAC or Apple Lossless?

FLAC is open source software. It is designed to be easy to implement in hardware so that it can be used royalty-free in many devices. Apple does not support FLAC in iTunes.

Apple Lossless is proprietary. Its encoding is faster than FLAC, but it doesn't matter.

One does not sound “better” than the other. Every lossless codec encodes audio data without loss of information.

The question, “Should I use FLAC or Apple Lossless?” is better asked, “Should I use iTunes or not?” See previous question, “Can I use iTunes?”

7.10. If I rip using Apple Lossless, can my iPod use AAC?

Yes. You can select the iTunes checkbox “Convert higher bit rate songs to 128 kbps AAC for this iPod” when your iPod is connected. This will allow you to rip your music losslessly and transcode to a compressed format for your iPod. You will pay a CPU penalty at sync time, however.

7.11. How do I alter FLAC tags?

You can use Media Monkey.

You can use the command line program metaflac that comes with the FLAC distribution.
