Points to remember when making MP3/ WMA/AAC files Common High bit rate and high sampling fre- quency are recommended for high qual- ity sounds. Selecting VBR (Variable Bit Rate) is not recommended. Selecting VBR may cause display of in correct playing time and jumpiness of playback. Playback sound quality varies depending on the encoding environment. Fordetails, refer to the user manual of the encoding software and the writing soft- ware in use.
Recording MP3/WMA/ AAC files on a CD media It is recommended not to write both CD- DA files and MP3/WMA/AAC files on adisc. If both CD-DA files and MP3/WMA/AAC files are on the same disc, tracks maynot be played in the correct order or some tracks may not be played at all.
When storing both MP3 data and WMA data on the same disc, sort and place them in different folders. Do not write files other than MP3/WMA/ AAC files and unnecessary folders on a disc. MP3/WMA/AAC files should be named to meet the standards and the file sys- tem specifications as shown below. The file extension “.mp3”, “.wma” or “.m4a” should be assigned to files based on their format independently. You may encounter a trouble in playing MP3/WMA/AAC files or displaying infor- mation of MP3/WMA/AAC files depend-ing on the writing software or CD recorder in use. This unit does not have a play list func-tion. It is recommended to write discs in Disc- at-Once mode even though Multi-ses-sion mode is supported.
