- FLAC - FLAC stands for Free Lossless Audio Codec. By encoding audio files with FLAC, the quality is exactly the same as the original audio file's quality is. This is exactly unlike the audio formats such as MP3 and WMA work -- these audio formats are called "lossy" and that means that when the original audio is encoded into the lossy audio format, some of the audio data is lost forever and can't be brought back by any means.
- Frames per second (FPS) - The number of picture images displayed per second, giving digital video the illusion of motion. Full-motion video, with no dropped frames, is considered 30 fps.
- Frame - A single picture in computerized digital video.
- Frame Rate - The number of images per second displayed in a stream of video.
- Graphics Interchage Format (GIF) - A graphic file format used to save cartoons, line-art and flat illustration. more...
- GSM - Compressed WAV format. Good for keeping of human speech.
- G.726 - Used for computer telephony. Good for keeping of human speech.
- ID3 - small file that can be attached to an MP3 that contains album, artist, track, and other info. more...
- Image Resolution - The amount of information stored in eacg image that is measured by pixels per inch (ppi) or dot per inch (dpi).
- ISO - International Standards Organization responsible for defining international standards. more...
- Joint Photographic Experts Group (JPEG) - A graphic file format used to create compact graphics. more...
- jitter correction - jitter occurs with digital audio extraction (ripping)or when digital audio is converted to analog. This correction feature helps restore the audio to its original condition
- kbps - "kilobytes per second", a measurement that is used to judge the size of an audio file. more...
- Lossless data compression -As the name implies, lossless compression retains all of the data of the original file as it's converted to a smaller file size. When a lossless file such as a TIFF is opened, algorithms restore all compressed information, creating a duplicate of the source file. Lossless compression is generally preferred for creating high-quality or professional-grade audio and video files where it's important to retain fine detail.
- Lossy data compression -With this kind of compression, some of the source file's information is discarded to conserve space. When the file is decompressed, this information is reconstructed through algorithms, usually resulting in some loss of sound quality or image detail when compared to the original. Generally, the higher the resolution of the compressing file, the less the degradation. An MP3 file with a resolution of 256 Kbps, for example, tends to sound more like the source file than one made at 64 Kbps.
