1, the file size is different. Lossless sound quality is the largest, followed by high sound quality, and finally ordinary sound quality.
2. The process is different. At first, the recording is lossless, and then compressed according to different needs, lossless sound quality-high sound quality-ordinary sound quality.
3. The format is different. Songs with lossless sound quality are generally in WAV format, songs with high sound quality are generally in APE, FLAC, TTA and TAK format, and songs with ordinary sound quality are generally in MP3 format.
It is normal not to hear the difference between the two, because everyone uses the onboard sound card of ordinary PC or NB computer to decode, and with ordinary multimedia headphones or multimedia speakers, these schemes are all for entertainment.
If you want to hear the difference:
1, please use CD player+professional amplifier front and rear stage +HIFI speaker, this set of the most entry-level down quickly 10 thousand.
2. To use PCHIFI, you need to use a high-quality independent sound card+professional power amplifier+high-end headphones, or PC+USB/ fiber decoder+professional power amplifier +HIFI speaker.
Extended data:
Songs that don't lose sound quality are generally in WAV format. As the standard of digital music file format, WAV has a large capacity and is inconvenient to use. Therefore, we usually compress it into MP3 or WMA format. Compression methods include lossless compression and lossy compression. Generally called high sound quality and ordinary sound quality.
All the songs played in high quality can be heard clearly! And there will be noise when the sound quality is low. There are: 192K 128K 64K 320K music on the internet, which is recognized as high-quality music.
We often see the lossy compression of MP3, WMA and OGG. As the name implies, lossy compression is to reduce the audio sampling frequency and bit rate, and the output audio file will be smaller than the original file.
Another kind of audio compression is called lossless compression, which can reduce the volume of the audio file on the premise of 100% retaining all the data of the original file, and the compressed audio file can reach the same size and bit rate as the source file after recovery. Lossless compression formats include Shorten, APE, La, FLAC, WAV, WavPack, LPAC, WMALossless, AppleLossless, TTA, Tak, TAC (exclusive to Tencent), OptimFROG, etc.
At present, the common and mainstream lossless compression formats are WAV, APE, FLAC, TTA and TAK. Among them, WAV has the best sound quality. Its audio code is as high as several thousand K, with a wide range and purer sound quality. Followed by APE, the code rate is generally around 600 to 1000, and each song is generally more than 40 megabytes.
