Round 20: Tossup 12
This type of data is encoded with a “code-excited” variant of LPC developed by Schroeder and Atal. This type of data may be subject to a “continuously variable slope” variant of another algorithm that iteratively represents states through deltas. Encodings of this type of data may use either the A-law or mu-law algorithms, the former of which sets a standard value of 87.6 in Europe. Transmission of this type of data is the origin of the DS0 (“D-S-zero”) standard. The smoothness of this type of data is controlled using “hard knee” or “soft knee” compression. Lossless compression of this type of data is often stored in FLAC files, a specific implementation of pulse-code modulation. Particularly high-quality instances of this type of data have a 44.1 kilohertz sampling rate. For 10 points, name this type of data stored in mp3 files. ■END■
