binaries are used to represent each sample value, also known as the quantization bit. The quantization bits of a sound signal are typically 4,6,8,12 or bits.By sampling frequency and quantization precision can be known, relative to the nature of the signal, audio encoding can only be achieved infinitely close, in computer applications, to achieve the highest level of fidelity is the PCM code, usually PCM conventional lossless coding.3.

process of getting confirmation from the library. At this point, when the main library waits for slave ack, although the current client is not returned, the transaction is committed and the other client reads the committed transaction. If the slave side has not read the events of the transaction, and the main library has crash, then switch to the standby repository. Then the previously read transaction is gone, and a phantom reading occurs. As shown, the picture is quoted from Loss-less semi-sy

There are three ways to do image I/O in Java (that is, read pictures and write pictures, and do not involve complex image processing): The Java image I/O API, which supports common images, is built from Java 2 version 1.4.0. Home: http://java.sun.com/javase/6/docs/technotes/guides/imageio/index.html Image I/O Tools in JAI support for more picture types, such as Jpeg-ls, JPEG2000, and TIFF.

, the image size is MxN, and the signal difference across each horizontal line is calculated: First, the block effect is defined as the average of the signal difference between the left and right cross-boundary: Then calculate the mean of the signal difference in the block: Then calculate the zero-crossing (ZC) rate, ZC is the boundary across zero meaning, that is, the value of the adjacent two points of the product is a negative, that is, a negative, so for [1, N-2] in the range of Y, define th

Of course, good articles and resources also need the support of the park friends, If you have help, do not stingy mouse oh, your support is my original motivation. Back to Table of Contents 2. Basics of compression formats and algorithmsData compression is the process of representing information in a specific encoding mechanism with data bits (or other information-related

One: GIF (Graphics interchange Format)Brief introductionThe GIF Graphics Interchange format is a bitmap graphics file format that reproduces true-color images in 8-bit colors (that is, 256 colors).It is actually a kind of compressed document, using LZW compression algorithm to encode, effectively reduce the image file on the network transmission time.It is one of the most widely used image formats for network transmission at present.Advantages1. Excellent compression algorithm to a certain exten

Book on Exercise: P443-9 no redundancy of the source can also be compressed? Why?Answer: yes. Because redundancy provides the basis for a compressed signal, it also improves communication efficiency. Lossless compression and lossy compression. For the source of redundancy, lossless compression and lossy compression can be achieved, determined by the degree of compression. Only lossy compression can be perfo

If you want to know the relationship between the MP3 frequency, bit rate, bit rate, and sound quality, the higher the frequency, the higher the bit rate, the better the sound quality. It seems that most of the MP3 frequencies are 44100hz. The bit rate is 128,192. The frequency mentioned here is the sampling rate, which is usually 44100khz, because it is the standard of music CD.Every song is captured from Cd, converted into wav files, and then converted into MP3 using lame and other software. So

JPEG image decoding and jpeg Decoding Introduction JPEG is a widely used standard method for compressing images. JPEG is the abbreviation of JointPhotographicExpertsGroup. A file in this compression format is generally called JPEG. The common extensions of such files include: .20.2.16.j2.16.jpgor .jpe. among them, the most powerful one is .jpg. JPEG/JFIF is the most common image storage and transfer format on the Internet. However, this format is not suitable for drawing lines, text, or icons b

What is ape? Is it a music format? Best Answer Ape is actually a lossless compression audio format. Massive WAV audio files can be compressed to ape by using the monkey's audio software. It is often used for network audio file transmission, because the size of the compressed ape file is more than half the size of the wav source file, which can save the transmission time. More importantly, the wav files obtained after decompression and restoration t

What is Ape? Sounds like a format for music? Best Answer Ape is actually a lossless compressed audio format. Large WAV audio files can be monkey ' s audio this software to "thin body" compressed into ape. Very often it is used as a network audio file transfer, because the compressed ape file capacity than the WAV source file smaller than half, you can save the time spent transmitting. More importantly, through the monkey ' s audio decompression after

use the character set number of the three-time codec used in the deposit phase as C1,C2,C3 (figure one from left to right), and the three character sets when taken out are numbered C1 ', C2 ', C3 ' (left to right). So when you deposit it, Bash C1 uses UTF-8 code, and when you take it out, C1 ' We use the Windows terminal (the default is GBK code), and the result is almost certainly garbled. Or in the MySQL when the set names UTF8 (C2), and when the use of the set names GBK (C2 '), then the resu

data on the hard drive is decompressed when data is needed. At present, the compression algorithms used in real-time databases at home and abroad are usually divided into two types: lossless compression and lossy compression. 4.1 Lossless compressionMost of the information expression has a certain degree of redundancy, by using a certain model and coding method, can reduce this redundancy. Huffman coding i

the difference is that it is completely free, open, and without patent restrictions. Vorbis is the name of this audio compression mechanism, while Ogg is the name of a plan designed to design a completely open multimedia system. Vorbis is also lossy compression, but the loss is reduced by using more advanced acoustic models. Therefore, Ogg encoded at the same bit rate sounds better than MP3. 11. Ape is a lossless compression audio format, which com

that the file size is large, and zooming in and out of the image is distorted. lossy compression and lossless compressionlossy compression is the processing of image data, removing the details of those images that are ignored by the human eye, and then filling them with gradients or other forms using nearby colors. This can greatly reduce the data volume of the image information, without affecting the image restoration effect.JPG is the most co

Causes of MySQL garbled characters1. the encoding of the corresponding link during storage and retrieval is inconsistent This will cause garbled characters to be obvious. The character sets used for encoding and decoding in the stored phase are C1, C2, and C3 (from left to right). The three character sets are numbered C1' and C2' in sequence ', c3' (left to right ). So when the bash C1 is stored in the UTF-8 encoding, take out, C1 'we use the wi
