Musical Instrument | A standard language of control messages that provides for communication between any |
Device Interface (MIDI) | |
| be controlled via MIDI. |
|
|
Normalize | Refers to raising the volume so that the highest level sample in the file reaches a user |
| defined level. Use normalization to make sure you are using all of the dynamic range |
| available to you. |
|
|
Nyquist Frequency | The Nyquist Frequency (or Nyquist Rate) is one half of the sample rate and represents the |
| highest frequency that can be recorded using the sample rate without aliasing. For |
| example, the Nyquist Frequency of 44,100 Hz is 22,050 Hz. Any frequencies higher than |
| 22,050 Hz produce aliasing distortion in the sample if no |
| recording. |
|
|
Offline Media | A media file that cannot be located on the computer. If you choose to leave the media |
| offline, you can continue to edit events on the track; the events point to the original |
| location of the source media file. |
|
|
| the hard disk rather than stored in RAM if they are longer than three seconds. Things such |
| as cymbal crashes and sound bites could be considered |
| Unlike loops, |
|
|
OPT | A |
| ins provide tools for working with MIDI such as edit views, effect processors and filters, |
| arpeggiators, and |
|
|
Pan | To place a mono or stereo sound source perceptually between two or more speakers. |
|
|
Peak Data File | The file created when a media file is opened for the first time. This file stores the |
| information regarding the graphic display of the waveform so that opening a file is almost |
| instantaneous. This file is stored in the directory where the audio file resides and has a .sfk |
| extension. If this file is not in the same directory as the audio file or is deleted, it is |
| recalculated the next time you open the file. |
|
|
Proxy File | Working with certain types of media files with particular audio compression schemes can |
| be inefficient and slow. To compensate for this, audio proxy files are created for these |
| formats to dramatically increase speed and performance. |
| The file is saved as a proprietary .sfap0 file, with the same name as the original media file |
| and the same characteristics as the original audio stream. The conversion happens |
| automatically and does not result in a loss of quality or synchronization. You can safely |
| delete audio proxy files at any time since these files are recreated as needed. |
|
|
Pulse Code Modulation | PCM is the most common representation of uncompressed audio signals. This method of |
(PCM) | coding yields the highest fidelity possible when using digital storage. PCM is the standard |
| format for WAV and AIFF files. |
|
|
Quantization | The correction of rhythms to align with selected note lengths or beats in a MIDI sequence. |
|
|
A proposed standard for controlling broadcast of streaming media. RTSP was submitted | |
Protocol (RTSP) | by a body of companies including RealNetworks and Netscape®. |
|
|
Redirector File | A metafile that provides information to a media player about streaming media files. To |
| start a streaming media presentation, a Web page includes a link to a redirector file. |
| Linking to a redirector file allows a file to stream; if you link to the media file, it downloads |
| before playback. |
| Windows Media redirector files use the .asx or .wax extension; RealMedia redirector files |
| use the .ram, .rpm, or .smi extension. |
|
|
Region | A region is a section of time used to subdivide your project into segments. |
|
|
Rendering | The process in which the project is saved to a specific file format like WMA or MP3. |
