These hardware parameters are not directly related to the attributes of the music file itself. Hardware parameters reflect the ability to restore the audio information expressed by the file, and the specific sound quality depends on the attributes of the file itself.

nowadays, mainstream computers are rarely equipped with special sound cards, and all audio processing is completed by the motherboard chip. Compared with PMP players, these players have special optimizations for playing music, such as using good quality decoding chips and designing excellent amplification circuits. In this sense, the sound quality of personal players such as mp3 is much higher than that of PC.

the sampling rate is the frequency at which audio signals are sampled during recording. Recording audio signals completely is not easy to use (there is a lot of information and it is not suitable for digital storage and transmission), so it is necessary to sample periodically to compress and record the corresponding values.

There is no necessary connection between the sampling rate and the hardware. The hardware only uses the file to complete the material basis of decoding output, and the sampling rate is only the attribute of the file itself. The higher the sampling rate, the larger the file and the better the sound quality. On the one hand, the larger the sampling rate, the greater the bit rate.

the sound quality is also closely related to the compression method. For example, MP3 is obviously not as good in sound quality as APE and FLAC.
