AAC

AAC is short for Advanced Audio Coding and refers to an audio compression technology standard used with MPEG 2 and MPEG 4.

Bit rate

This expresses data volume per second, or bps (bits per second) units. The higher the rate, the more information is available to reproduce the sound. Using the same encoding method (such as MP3), the higher the rate, the better the sound.

ID3 tag

This is a method of embedding track-related information in an MP3 file. This embedded in- formation can include the track title, the ar- tist’s name, the album title, the music genre, the year of production, comments and other data. The contents can be freely edited using software with ID3 Tag editing functions. Although the tags are restricted as to the num- ber of characters, the information can be viewed when the track is played back.

ISO9660 format

This is the international standard for the for- mat logic of CD-ROM folders and files. For the ISO9660 format, there are regulations for the following two levels.

Level 1:

The file name is in 8.3 format (the name con- sists of up to 8 characters, half-byte English capital letters and half-byte numerals and the “_” sign, with a file-extension of three charac- ters).

Level 2:

The file name can have up to 31 characters (in- cluding the separation mark “.” and a file ex- tension). Each folder contains less than 8 hierarchies.

Extended formats

Joliet:

File names can have up to 64 characters. Romeo:

File names can have up to 128 characters.

Linear PCM (LPCM)/Pulse code modulation

This stands for linear pulse code modulation, which is the signal recording system used for music CDs and DVDs.

m3u

Playlists created using the “WINAMP” soft- ware have a playlist file extension (.m3u).

MP3

MP3 is short for MPEG Audio Layer 3. It is an audio compression standard set by a working group (MPEG) of the ISO (International Stan- dards Organization). MP3 is able to compress audio data to about 1/10th the level of a con- ventional disc.

MS ADPCM

This stands for Microsoft adaptive differential pulse code modulation, which is the signal re- cording system used for the multimedia soft- ware of Microsoft Corporation.

Multi-session

Multi-session is a recording method that al- lows additional data to be recorded later. When recording data on a CD-ROM, CD-R or CD-RW, etc., all data from beginning to end is treated as a single unit or session. Multi-ses- sion is a method of recording more than 2 ses- sions on one disc.
