Appendix E Glossary
The glossary contains terms and their definitions that you may come across in the manual. This glossary not only includes terms associated with ACID® software, but also includes relevant industry terms.
An ACID project file that contains all information regarding the project including track | |
| layout, envelope settings, and effects parameters. In addition, all audio files used in the |
| project are embedded into the project file. |

|
Activation Code | This number is based on the Computer ID number of the computer on which the software |
| is installed. Each computer has a unique number, similar to a license plate. When you |
| register your copy of the software, Sony generates an activation code for you based on |
| the Computer ID number. Once you enter the activation code, the ACID application will |
| not time out. Since the activation number is based on the Computer ID, it is important |
| that you have the software installed on the computer where you will be using it. |

|
Adaptive Delta Pulse | A method of compressing audio data. Although the theory for compression using ADPCM |
Code Modulation | is standard, there are many different algorithms employed. For example, Microsoft's |
(ADPCM) | ADPCM algorithm is not compatible with the International Multimedia Association’s (IMA) |
| approved ADPCM. |

|
Aliasing | A type of distortion that occurs when digitally recording high frequencies with a low |
| sample rate. For example, in a motion picture, when a car's wheels appear to slowly spin |
| backward while the car is quickly moving forward, you are seeing the effects of aliasing. |
| Similarly, when you try to record a frequency greater than one half of the sampling rate |
| (the Nyquist Frequency), instead of hearing a high pitch, you may hear a |
| rumble. |
| To prevent aliasing, an |
| recording. Once the sound has been recorded, aliasing distortion is impossible to remove |
| without also removing other frequencies from the sound. This same |
| must be applied when resampling to a lower sample rate. |
|
|
ASIO | ASIO™ (Audio Stream In/Out) is a |
| Technologies AG. |
|
|
ASX File | ASF Stream Redirector file. See Redirector File. |
|
|
Attack | The attack of a sound is the initial portion of the sound. Percussive sounds (drums, piano, |
| guitar plucks) are said to have a fast attack. This means that the sound reaches its |
| maximum amplitude in a very short time. Sounds that slowly swell up in volume (soft |
| strings and wind sounds) are said to have a slow attack. |
|
|
Attenuation | A decrease in the level of a signal. |
|
|
Audio Compression | The Audio Compression Manager from Microsoft® is a standard interface for audio |
Manager (ACM) | compression and signal processing for Microsoft Windows. The ACM can be used by |
| Windows programs to compress and decompress WAV files. |
|
|
Audio Interchange File | An audio file format developed by Apple®. |
Format (AIFF) |
|

Audio Proxy File (.sfap0) | |
|
|
Bandwidth | When discussing audio equalization, each frequency band has a width associated with it |
| that determines the range of frequencies that are affected by the EQ. An EQ band with a |
| wide bandwidth affects a wider range of frequencies than one with a narrow bandwidth. |
| When discussing network connections, refers to the rate of signals transmitted; the |
| amount of data that can be transmitted in a fixed amount of time (stated in bits/second): |
| a 56 Kbps network connection is capable of receiving 56,000 bits of data per second. |
|
|
Beatmapped track | A file that has tempo information added to it as a result of going through the |
| Beatmapper® Wizard. |
