After years of verification, the code-driven Linear Prediction Model (CELP, Code Excited Linear Prediction) is one of the most popular speech codec models that are used to reconstruct speech quality. Speex and other CELP codecs are based on the CELP model. What is the main idea of the CELP model? 1. Use the linear prediction (LP, linear prediction) model to model the channel system; 2. Based on the speech generation principle, an adaptive CAPTCHA and

codec that we are not very familiar with. It should be said that AAC will replace MP3 in the future. It supports 96 KHz sampling frequency and 48 channels, as well as a variety of technologies such as SBR, providing high compression and high-quality audio. 4. MPEG-4 Part 2 MPEG-4 Part 10This is the h263 and h264 (AVC) We should be not very familiar with, in fact, the h26x series of protocols are all later added to the MPEG-4 protocol cluster, because

In Python, the processing of Chinese characters has always been a headache, a word is garbled, and the cause of garbled is not the same, sometimes Python itself default encoder settings are not correct, and sometimes the use of the IDE decoder is not correct, There are sometimes terminal terminal decoder is not correct, the same code in the Python2 on the normal operation, Python3 on it, anyway, there are many reasons for garbled, here are some of the bloggers have encountered some errors and so

When writing a file using Python, or when writing a network stream to a local file, in most cases you will encounter: Unicodeencodeerror: ' GBK ' codec can ' t encode character ' \xa0 ' in position ... The problem. There are a lot of similar files on the network about how to solve this problem, but nothing is encode,decode related, is this the real cause of the problem? No. Many times, we used decode and encode, tried all kinds of code, utf8,utf-8,gbk

In the course of learning webpy, there are unicodedecodeerror: ' ASCII ' codec can ' t decode byte 0xe6 in position 29:ordinal No in range (128) error After Baidu reference to the following article to resolve: Http://blog.sina.com.cn/s/blog_6c39196501013s5b.html Resolve Unicodedecodeerror: ' ASCII ' codec can ' t decode byte 0xe5 in position 108:ordinal not in Ran (2012-02-29 10:21:59) reprint label :

Using the python2.7, the runtime appears with the ' ASCII ' codec can ' t encode characters in position 0-8: Ordinal not in range (128) error, by searching for some articles to learn because PYT The default encoding used by the Hon System is ASCII encoding, but the characters in the operation of the code are not in the ASCII range, so the error is incorrect.Workaround:Add 3 lines of code before the code1 Import SYS 2 Reload (SYS) 3 sys.setdefaultencod

Java Implementation BASE64 codecAuthor: Chszs, reproduced in the note. Blog home:Http://blog.csdn.net/chszsBASE64 and other similar coding algorithms are often used to convert binary data into textual data, which is intended to simplify storage or transmission. In more detail, the BASE64 algorithm is primarily used to convert binary data into ASCII string formats.The Java language provides a good implementation of the BASE64 algorithm, the Apache Commons cod
