UTF-16: Variable-width encoding. Code points U+0000 to U+FFFF take 2 bytes, code points U+10000 to U+10FFFF take 4 bytes. Bad for English text, good for Asian text. UTF-32: Fixed-width encoding. All code points take four bytes. An enormous memory hog, but fast to operate on. Rarely used. In long: see Wikipedia: UTF-8, UTF-16, and UTF-32.
Lempel–Ziv–Welch. Lempel–Ziv–Welch ( LZW) is a universal lossless data compression algorithm created by Abraham Lempel, Jacob Ziv, and Terry Welch. It was published by Welch in 1984 as an improved implementation of the LZ78 algorithm published by Lempel and Ziv in 1978. The algorithm is simple to implement and has the potential for very ...
Variable bitrate. Variable bitrate ( VBR) is a term used in telecommunications and computing that relates to the bitrate used in sound or video encoding. As opposed to constant bitrate (CBR), VBR files vary the amount of output data per time segment. VBR allows a higher bitrate (and therefore more storage space) to be allocated to the more ...
A floating-point variable can represent a wider range of numbers than a fixed-point variable of the same bit width at the cost of precision. A signed 32-bit integer variable has a maximum value of 2 31 − 1 = 2,147,483,647, whereas an IEEE 754 32-bit base-2 floating-point variable has a maximum value of (2 − 2 −23) × 2 127 ≈ 3.4028235 ...
Mar 28, 2010 · If the most significant bit is 1, then you know there's one more byte to read, and you repeat the process, adding the next 7 bits to the current 7 bits. The MIDI format uses that exact encoding to represent lengths of MIDI events, in the following manner: ExpectedValue = 0. byte=ReadFromFile. ExpectedValue = ExpectedValue + (byte AND 0x7f) if ...
