hifi means lossless, hifi music player is lossless music player, the sound quality of hifi player is better than ordinary mp3.

Basic introduction to lossless music

1. When collecting natural sounds, the sampling scheme has determined the highest quality that the sound can achieve: sampling rate, number of sound bits, and channels. If there is data loss during storage, dissemination, and transcoding, the sound content is usually far different from the original content, and listeners who pursue high quality will not like such content.

2. 20 years ago, when computer memory was <1M and hard disk was <500M, it was meaningless to talk about music digitization and high-quality music. No one wants to hear sounds that are worse than the tape being twisted by a tape recorder. Hardware technology and software technology do not meet the requirements. When the memory is larger than the hard disk capacity of the past, we can pursue this. Software algorithms have also been implemented for a long time. So, we can pursue higher quality sound.

3. Lossless audio means that under the limitations of existing computing power and storage capacity, from the sampling of audio content to storage, editing, playback and other processes, high-level mathematical, lossless editing, Storage, high restoration playback, this is the so-called "lossless music". This is the highest audio quality requirement currently achievable.

4. This consists of three parts. The sound source must have a high sampling rate, no less than the number of channels of the playback device, and more than 16 bits. The transmission/storage/editing must be lossless, and the playback must use high-quality audio. Restorative playback device. However, due to data loss during audio digitization, in fact it can never be truly lossless.
