which gives a range of 256 amplitude steps, or 16 bits (2 bytes), which gives a range of 65536 amplitude steps. Other sizes, such as 12, 20, and 24 bits, are occasionally seen. Some king-sized formats even opt for 32 and 64 bits...
譬如"Windows XP 启动.wav" 的文件长度是 424,644 字节, 它是 "22050HZ / 16bit / 立体声" 格式(这可以从其 "属性->摘要" 里看到), 那么它的每秒的传输速率(位速, 也叫比特率、取样率)是 22050*16*2 = 705600(bit/s), 换算成字节单位就是 705600/8 = 88200(字节/秒), 播放时间:424644(总字...
PCM OUTPUT AND SAMPLING MODES The PCM4222 supports 24-bit linear PCM output data when the PCMEN input (pin 16) is forced high. The PCM output is disabled when PCMEN is forced low. The 24-bit output data may be dithered to 20-, 18-, or 16-bits using internal word length reduction ...
In various embodiments, the pulse decoder (embodied as a special case of the third mapping function 250) produces an output data stream which has the same number of bits per sample and the same data rate as PCM data, but directly represents a digitally encoded data stream. This is similar ...
In the G.711 WBE, the input wideband signal is encoded in three Layers. The first Layer (Layer 1; the core) encodes the lower band of the signal in a G.711-compatible format at 64 kbps. Then, the second Layer (Layer 2; narrowband enhancement layer) adds 2 bits per sample (16 ...
Every byte of a log PCM data chunk maps to a signed 16-bit linear PCM sample. [TODO: Add either the conversion tables or conversion formulas] Differential PCM Values are encoded as differences between the current and the previous value. This reduces the number of bits required per audio samp...
16-bit data words by the HEADU PROCESSOR 21. These words contain the SUBU ID and a SUBU command function. When the t0 pulse occurs, the bit rate clock BRCL begins clocking the serial data out of the register on the SSNRZ line at the 1.544 MB/s rate. When 31 bits have been clocked...
