Glossary

BPM Studio

Peripheral

An auxiliary device, such as a printer, modem,

storage system or external Remote Control Unit

that works in conjunction with a computer.

Pitch

Professional CD players allows the user to change

the playback speed of a track. This is neccesary

e.g. for synchronizing two titles with different

speed (BPM - beats per minute) resp. playback

with the same speed. The measure of the

changed speed in contrast to the original speed

is called "pitch" and is stated in percent. A pitch

value of +100% means that the title will be played

with the double speed, -50% plays the titel with

the half of the speed.

Pitch Bend

Using the Pitch Bend function a temporary

increaseing or decreasing of the pitch is possible.

This is usefully if two titles, already played back

with the same speed, shall be synchronized in

beat. By pressing a Pitch Bend button the speed

will be increase or decrease continuously. At

releasing the button the title returns continuously

to its originally speed as well. With the Pitch Bend

buttons the beats of two titels can synchronized

exactly and very small corrections of both players

are possible.

Rip, Ripping

Ripping is act of reading an Audio CD using the

CD-ROM drive of a computer and storing the

information onto a hard disk. IBM PC's use the

Wave format for ripping and Mac computers use

the AIFF format. The generation of an MP3 file

can happen either after a rip or simultaneously

as the rip is being performed.

Root Directory

When a floppy or hard disk is formatted for use,

this particular directory is created. It is called the

Root Directory. It contains important systematic

files and is the first level for subdirectories.

Selection box

This is a text box that enables a choice between

'ON' and 'OFF' or 'Yes' or 'No'.

Subdirectory

This is a directory within a directory.

Subdirectories are used to organize files. This

makes it easier to find files.

Tempo

Tempo is the original speed of a title. The song

writer or interpreter defines this speed. With the

Pitch function of most professional CD players,

and BPM Studio as well, this speed can be

changed in a wide range.

Text field

This is a rectangular box where text can be

entered. There are many different ways to use

these Text boxes for example: changing standard

text entries or other pretending text (if the change

is allowed), entering necessary program

information to enable the program to work and

also editing title entries in the ID3V3 tags for later

use.

Track

We refer to a Track as recorded title, a piece of

music or a song.

VBR Files

Compared to CBR (Constant bit rate), the encoder

analyzes the title's VBR (variable bit rate) and

chooses an exact compression algorithm for

every frame adapted by the MP3 encoding. This

allows for better compression at higher bit rates

compared to the compression of a simple signal

or CBR.

WAVE file

This format is used by Windows to store audio

signals free of sound quality loss. Examples of

sources of this sound quality could be: Audio

CD's, Film soundtracks and records. All signals

are copied exactly. The quality in the WAV file is

the same as in the original data. But, in order to

have this kind of quality it is necessary to have a

large amount of free hard disk space.
