complex, and common programs are difficult to implement their encryption and decompression algorithms. However, ACM and VCM technologies are introduced for Windows 98 operating systems that provide strong support for multimedia, it is used to manage all audio and video encoding and Decoder (CODER-decoder) in the system, that is, codecs, which is used to implement audio and video data encoding and decoding

Categories: Unity, C #, VS2015Date Created: 2016-04-05 I. INTRODUCTIONThe choice of audio file resources should be based on the principle of smooth, trouble-free operation. The commonly used audio files are listed below.. AIFF is converted to uncompressed audio when importing, which is best for short sound effects.. WA

suitable for this encoding format. · AMR: The full name of AMR is "adaptive multi-rate". It is also another encoding format specially optimized for "speech" and is also suitable for Low Bit Rate environments. · ALAC: The full name is "Apple lossless". This is an audio encoding method without any quality loss, that is, lossless compression. In actual use, it can compress 40%-60% of raw data. The decoding sp

bit rate too much,The screen effect is not obvious. While MKV is H.264 encoded and used for HD videos. The 1080p image rate reaches 30 Mbps.Of course, the formula for calculating files not compressed is different:Sound:, data volume (bit/second) = (sampling frequency (HZ) * sampling bit (BIT) * number of channels)The number of single-channel channels is 1, and the number of stereo channels is 2.Data size * time/8 = total file bytesFor example, CD is

) The MP3 full name is MPEG-1 Audio Layer 3, which was incorporated into the MPEG specification in 1992. The MP3 is capable of compressing digital audio files with high sound quality and low sample rate. In other words, audio files (mostly large files, such as WAV files) can compress files to a lesser extent in th
