mp3 file size compressor

Give your cool dog software users A detailed explanation of how cool dogs can change the size of MP3 files. Method Sharing: 1, MP3 file is mainly due to high bit rate (such as 320Kbps), using the cool dog's own format conversion tool can convert a bit-rate file to

First get all the MP3 files under the path path of the SD card and save the file name and size to the list array (this code is defined in the Fileutils Class):/*** Read the name and size of the Mp3 file in the directory*/Public li

language usedThe frame size is the integer size represented by four bytes. 2. Data frameData frames tend to have multiple, as to how much, determined by file size and frame size. Each frame has a header header, the length is 4BYTE (32bit), the frame head may have two bytes

Based on the analysis in the previous two articles, frames are divided into tag frames and data frames. The MP3 file types are divided based on the data frame types. The file types are shown in the following table: Equal bit rate (constant bitrate) CBR MP3 file

protection flag. This frame is considered invalid when it is set. C -- read-only flag. When this frame is set, it cannot be modified (but I didn't find a software to ignore this flag) I -- compression flag. When set, one byte stores two BCD codes to indicate numbers. J -- encryption mark (I have never seen any MP3 file tag encrypted) K -- group flag. It indicates that this frame and other frames are a grou

is determined by the file size and frame length. The length of each frame may be unequal or equal, determined by bitrate; each frame is divided into two parts: the frame header and the data entity. The frame header records information such as the bit rate, sampling rate, and version of MP3. Each frame is independent of each other. 3. id3v1 Contains the author, c

and several tag frames or an Extended Tag header. Information about tracks, such as titles and authors, are stored in different tag frames. It is not necessary to expand the tag header and tag frame, but each tag must have at least one tag frame. The tag header and the tag frame are sequentially stored in the MP3 file header. (1) label Header Record the header of the 10-byte ID3V2.3 In the first sequence o

I encountered a problem. When the post object can upload txt files below 1 MB, the byte set POST object upload fails to upload mp3 files above 1 MB. I encountered a problem. When the upload of a txt file below 1 MB after the post operation succeeds, the upload of A mp3 file above 1 MB after the byte set POST operation
