Bit rate refers to the audio data stream contained in each sample. The unit is bps.
Bit rate can also be understood as the sampling rate of converting digital sound from analog format to digital format.
The higher the sampling rate,
The better the sound quality after restoration.
The closer the recorded sound is to the original sound.
The comparison between the bit rate value and the real audio is as follows:
16KBPS= telephone quality.
24KBPS= increase the telephone quality, short wave broadcasting, long wave broadcasting and medium wave broadcasting of European standards.
40KBPS= American standard medium wave broadcasting.
56KBPS= voice
64KBPS= Improve voice (the best bit rate setting for ringtones and the best setting for mono MP3 players).
1 12 kbps = FM stereo radio.
128KBPS= magnetic tape (the best setting for mobile stereo MP3 players and low-grade MP3 players)160kbps = hifi (the best setting for high-grade MP3 players).
192KBPS=CD (the best setting value for high-end MP3 players)
256KBPS=Studio Music Studio (for music lovers)
Sampling rate is the sampling frequency of analog signal as digital signal, which is related to sound quality. The larger the sampling rate, the better the high-frequency reproducibility of sound files. The following are different qualities corresponding to different sampling rates:1.11.025 Hz. The sound at this sampling rate is similar to AM broadcasting, 2. 22,050 Hz, close to FM broadcasting, but 3 lower. 32000Hz, 4 times higher than FM broadcasting. 44. The sound with sampling rate of 100 Hz has reached the sound quality of CD audio 5. 48,000 Hz, and sound with a sampling rate of 6. 96000Hz has reached the sound quality of DVD audio. The higher the sampling rate, the larger the disk space occupied by the final sound file. Usually we can choose the sampling rate of 44. 1KHZ.
It is meaningless to compare MP3 and WAV in general.
Usually, MP3 is used as the music format.
Then WMA,
WAV format is not used much.
I don't know if you can understand this,
You can leave me a message if you have anything unclear ~
