WMA is a digital music format promoted by Microsoft, under the premise of the same sound quality as mp3, the volume can be reduced by half, which almost doubles the capacity of the mp3 player.

You can easily transcribe CD to WMA through the media player that comes with Window. However, WMA has a disadvantage: Due to the music copyright issue, some WMA files cannot be simply copied to the mp3 player for playback. Of course, the higher the sound quality, the larger the file size. 320kb mp3 files are as large as 9m, and an mp3 with 128m of memory can only hold about 12 songs, which is highly impractical.

The size is the ideal choice. Of course, if you have the money, it would be better to buy an mp3 hard drive, even if you put 320kb files on it, it will be easier to enjoy high quality music.

The compression rate of the songs we download from the Internet is usually relatively low, often only 96kbps or even less, and the effect is not very ideal.

This is a practice where websites deliberately lower the compression rate due to download speed and copyright issues. To enjoy real sound quality, the best way is to find a better quality CD disc and compress it yourself. Generally speaking, the sound quality of an mp3 file with a compression ratio of 192 kbps is relatively good. When played with a good mp3 player, the effect is very similar to md. If compressed to 320 kbps, the sound quality is very good. similar to that of a CD player Hard to tell the difference. (Excluding those with golden ears, of course)

Of course, the sound quality performance of mp3 using STMP3410 decoder chip is not the same and sometimes even very different. The reason lies in the internal circuit design of the mp3, the soldering process, the material of the circuit board, and the difference between various manufacturers, especially There is a big difference between the big manufacturers and some non-brand manufacturers. These are also the key factors that affect the work of the decoding chip and the sound quality output. Take two high-end machines that also use the STMP3410 chip and compare the unbranded machines to understand.
