Adaptive Transform acoustic Coding(ATRAC) Is a family of proprietary audio compression algorithms developed by Sony. minidisc was the first required cial product to in1_ate ATRAC in 1992. ATRAC allowed a relatively small disc like minidisc to have the same running time as CD while storing Audio Information with minimal loss in perceptible quality. today ATRAC is used in your Sony-branded

Did not find the reprint function where ... So I can only copy it over. Always want to video audio codec technology to do a simple summary, but suffer from the time is not sufficient, has not been able to complete.

and easy to process in real time.2. 1.1.2 what is G.711 encoding?A:G.711 suggests a typical compression codec method using PCM waveform encoding to achieve higher speech quality, but the data compression rate is low.G.711 it is recommended to describe the μ-law (A-Law) compression of PCM, as shown in:The sampling rate is 8 kHz, and the 12-bit linear A/D is transformed into A digital signal. After the logarithm PCM, the data is compressed to 8 bit, an

Thank the great God to share, although now still do not understand, keep everyone together to seePS: A lot of people don't know how to read "FFmpeg". It reads "EF EF em Peg"0. Background knowledgeThis chapter focuses on where ffmpeg are used (here are just a few of the many I know, in fact much more than this). To illustrate: FFmpeg is very important.Use FFmpeg as the kernel video player: Mplayer,ffplay, shooter player, Storm av, kmplayer,qq av ... Use FFmpeg as the DirectShow Filt

In the CSDN on this period of time, contact with a lot of people in the same industry, especially the use of FFmpeg audio codec, some have many years of experience in the "Great God", some have just started to learn beginners. In the process of discussing with you, I suddenly found a problem: there seems to be an insurmountable gap between the "great God" and the beginner. The "Great God" is highly skilled

Libraries with this name have ffmpeg projects and LIBAV projects, but they are incompatible with each other.Libavcodec is an integration of many open source multimedia applications and frameworks.
