My desktop system records beautifully, but my lap top takes forever and the MP3s skip all over. What is wrong?

Unfortunately, the same qualities that make a CD-Rom great for a portable computer make it very difficult to obtain acceptable recording quality with most MP3 encoders. MusicMatch Jukebox is no exception here. It is quite possible that from this unit, you may never get a clean recording and if possible, may want to do your recording on a desktop unit instead and use your lap top for playback only.

What compression rates does MusicMatch Jukebox offer?

Tracks compressed using MP3, CD quality will be compressed at 12:1. Tracks compressed using MP3, near-CD quality will be compressed at close to 18:1. Tracks compressed in FM Radio Quality (56 kbps or 28 kbps) will be compressed 70:1.

The standard 44 kHz/128kbps is generally recommended, but you can choose CD Quality at 160 kbps as well. To change the recording quality settings, go to Options/Recorder/Quality. See also Constant Bit Rate and Variable Bit Rate compression modes in the MusicMatch help file or in the Advanced Users Guide.

Can I make WAV files with MusicMatch Jukebox?

Yes, you can. These tracks will be saved to the directory you choose, and will not be included in your Music Library.

When does the compression take place in the recording process?

File extraction and compression are performed in parallel. You do not have to worry about filling up your disk with WAV files - only the compressed file will be saved on your PC.

Can all CD-Rom drives record music in digital format?

No, only CD-Rom drives that support the Redbook audio format, and have a reasonable level of seeking accuracy, can record music from CDs to computer hard drives in digital format. Many older CD-Rom drives, and some new ones, do not support this capability. You will need to use the analog record option if your drive does not support digital audio extraction. You can change to analog recording by choosing Options/Recording/Settings and checking the box next to Analog Recording in Recording Mode.

What is the difference between analog and digital recording?

The main difference is the speed with which you can record. Analog recordings will always be 1x the play speed, whereas digital recordings will be faster (depending on your drive, PC processor and compression type selected). The sound quality difference of analog recording compared with digital should be minimal. The amount of conversion errors you hear are primarily dependent on your PC system. Factors that will affect the sound quality are the soundcard and the required level of multimedia real-time performance.

How long does it usually take to record a song from a CD to your hard drive?

In addition to the compression option, this also depends largely on the processing power of your PC. The speed is also determined by the seeking accuracy of your CD-Rom drive. Your drive's seeking accuracy will determine the number of errors that occur as audio files are extracted from a CD during recording. The larger the number of extraction errors, the more time it will take the error correction routines in MusicMatch Jukebox to fix them. MusicMatch Jukebox has a record option that allows you to elect greater error correction if necessary. If you select error correction, recording time will usually
