Interface File Format (AIFF) was developed by Apple and is the audio format for Macintosh
computers. This format does not support compression.
rate is the amount of information (or bits) that is transferred per second (bit per second
or bps). MP3s are measured in thousands of bits per second (kbps) and the higher the kbps,
the higher the sound quality. 128 kbps is the standard MP3 bit rate.
|Blade / BladeEnc
open source WAV to MP3 encoding engine used in many MP3 software programs.
area of memory used to speed up access to devices such as a CD-R/W. It is used for
temporary storage of data read from or waiting to be written to a CD-R/W.
a CD burner requests data from the write buffer and there is no data, the write laser
doesnt have any more data to write therefore causing a buffer underun. The CD
recording cannot be interrupted in mid session and when this occurs you will have a
defective CD burn.
is a technology developed by Sanyo, which helps prevent buffer underruns.
online based Compact Disc Database (CDDB) that allows you to download artist names, album
titles, track names etc. This information is displayed in your MP3 player.
Disc Recordable (CD-R) is a recording device that allows you to record data and audio CDs
only one time.
Disc Rewritable is an extension of CD-R whereby you can rewrite data or audio to the same
CD multiple times.
Compact Disc-Read Only Memory (CD-ROM) is designed to store data in the form of text,
graphics and audio. CD-ROMs use the Yellow Book standard as published by Philips.
book CD standard that allows album titles, artist names, and song titles to be embedded on
an audio CD. Some CD players can read this data.
codec (compression/decompression) is any technology that is used for compressing and
decompressing data such as audio (MP3) or video (MPEG).
|Constant bit rate (CBR)
Bit Rate is an encoding method that maintains the same bit rate across the entire audio
|Digital audio extraction (DAE)
Audio Extraction (DAE), also known as CD ripping, is the process of extracting audio from
CD which is copied to hard drive in WAV format.
process of converting an MP3 to WAV. This may be done in order to edit your WAV file.
|Disc at once (DAO)
the CD burning process, the entire CD is written at once without the write laser being
process of converting a WAV to MP3 audio format. This reduces file size while
maintaining sound quality.
tagging system that allows you to put music information such as artist, song title, album
title, lyrics within your audio files.
Organization for Standardization (ISO) is a non-governmental global organization
established in 1947 that works to develop standards across goods and services.
widely used data interchange format adopted in 1987. CDs created in this format can be
read by Unix, Macintosh and Windows computers.
is caused by the inability of many CD-ROM drives to accurately seek a specific
sector on an audio CD therefore resulting in pops or clicks when listening to the
ripped audio track.
an Mp3 Encoder (LAME) is an open source MP3 encoder engine used in a large
number of MP3 software titles.
is an acronym for MPEG layer 3, which is a compressed audio format. A compression ratio of
up to 12 to 1 compression is possible, which produces high sound quality.
is the combination of mp3 and SBR. SBR (Spectral Band Replication) is a new audio coding
enhancement tool. It improves the efficiency and fidelity of conventional audio codecs and
offers full audio bandwidth at virtually all bitrates.
or more commonly known as MPC, is a free high quality format partially based off MP2.
MusePaCk is a VBR (variable bitrate) only format
Moving Picture Experts Group (MPEG) is a working group under the International
Organization for Standardization (ISO) that sets the standards for encoding audio and
video in digital format.
to volume differences between audio tracks, normalization allows you to set the volume
consistent between tracks during the encoding or burning process.
non-proprietary, patent free open source audio compression format that is similar to MP3.
|Peer to Peer (P2P)
sharing and delivery of user specified files among groups of people who are logged on to a
file sharing network. Napster was the first mainstream P2P software that enabled large
scale file sharing.
|Red Book CD
audio standard defined by Sony and Philips in 1980 that was published in a red binder,
hence the name.
|Ripping (CD Ripping)
process of digitally extracting audio from CDs to your hard drive in WAV format.
audio allows for on-the-fly listening to an audio file. The audio file is streamed
from a server where it is received and stored in your buffer on your computer. If
you use WinAmp or RealAudio, you will see a message displayed telling you that the audio
file is being buffered. The file is not saved on your hard drive.
|Track at once (TAO)
the CD burning process, each track is written on its own and the writer laser is turned
off before starting to burn the next track. This causes a 2 second gap between
|Variable bit rate (VBR)
Bit Rate adjusts the bit rate depending on the sound. For example, if there is silence in
a song, the bit rate would decrease and if there is a full symphonic sound the bit rate
would increase. VBR offers a higher sound quality at a smaller file size.
is an audio compression format. It is similar to MP3, but is now out of date
file format for storing digital audio data in waveform.
Media Audio is Microsoft's audio encoding format that is starting to gain popularity due
to its high quality output at lower file sizes. A 96 kbps (and in some tests a 64 kbps)
wma file is equivalent in sound quality to a 128 kbps MP3 file.
CD-ROM standard defined by Sony and Philips in 1983 that is an extension of the Red Book
standard. This standard enables CDs to contain data along with audio.
