WAV is a lossless sound file under Windows, the file holds the audio PCM information and the player plays that music when most information is made, he has two blocks, the first block is the format block, the second block is the data blockFirst, the format block, the format block with a picture can be explained, as followsUsing Winhex to analyze a WAV audio file, Han Lei's farewell message is as followsBy co
Another product of the company, when monitoring CTI, the recording format is PCM.To play in IE, You need to convert it into a standard WAV. previously, I used a com library for conversion. Now I can't use that library for various reasons (64-bit support is not good), So I implemented it in Java. The basic code is as follows.In fact, WAV is only a PCM file with the relevant file header and description inform
Dat data format 5A 5A 5A xx (frame header) the frame header is followed by the first ad Channel 1 data (2 bytes), the second Ad Channel 1 data (2 bytes), and the first ad Channel 2 data (2 bytes ), the second AD Channel 2 data (2 bytes ),......... The first ad Channel 6 data (2 byte) and the second Ad Channel 6 data (2 byte ). I extracted the first ad Channel 6 data. Then convert it to 16 bit, and then-32768 to positive and negative signals, because ad collects 0-5 V signals, minus 32768 to conv
