How many KB is the best sound quality for mp3? Part 2
What’s more, there are some unscrupulous manufacturers on the market who use discarded or recycled second-hand FLASH chips, coupled with inferior circuit design, quickly made an mp3 and sold it to the market.
Usually the price of this kind of mp3 is very low, and the 128m memory is sometimes cheaper than the same capacity U disk, and the sound quality can be described as rubbish. Come to think of it, we all know that manufacturers have to survive on such a small profit, unless there is something in the mp3, who will make it for free?
So when you come across this kind of mp3, you should pay more attention, no matter how good the sound quality is, it can’t be better. Other decoder chips such as Sigmatel’s STMP1342, Telechip’s TCC730, Samsung’s S3C2410, etc. will not be discussed in detail due to their similar performance.
With the deepening of the market, some powerful manufacturers are also constantly exploring to dedicate the best sound quality to consumers. JNC’s new SSF-800 machine uses the SIGMATEL3420 chip, and the sound quality is very impressive. The next new mp3 just released by iriver uses the most powerful SIGMATEL3520, which is worth waiting for. The good news is that the Meizu me launched by the national brand Meizu also uses the SIGMATEL3520 decoder chip, which is the first time for a national brand. It appears that the national brand is slowly creeping into the ranks of premium sound effects as well.
Second, the quality of music playback files The
decoding chip is important, but in order to enjoy high-quality music, the factor that affects the sound source itself is very large.
In turn, the quality of the audio source depends on the music file format and compression ratio. Nowadays, the most popular music formats are of course mp3 and wma, almost all mp3 players support these two formats. MP3 should be considered as the most lossy compressed digital audio format currently used by users. The mp3 files that we usually listen to have a bit compression rate of 128kbps, the compression rate is about 1:10, and the file size is usually only 4m. to a more balanced position. 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 mp3 files 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 similar. to the CD player It’s hard to tell the difference. (Of course, those with golden ears are excluded)
