8K is the sampling rate, which is 8*1024 samples per second; 8bit is the bit rate, which indicates how many bits per second the encoded (compressed) audio data needs to be represented. Generally speaking, the higher the sound quality, the better.

●Bit rate value compared with real audio:

16Kbps=telephone sound quality

24Kbps=increased telephone sound quality, shortwave broadcast, longwave broadcast, European standard medium wave Broadcast

40Kbps=American standard medium wave broadcast

56Kbps=Voice

64Kbps=increased voice (optimal bit rate setting value for mobile ringtones, mobile phone mono) The best settings for channel MP3 players)

112Kbps=FM stereo broadcast

128Kbps=Tape (the best settings for mobile phone stereo MP3 players, the best settings for low-end MP3 players The best setting value)

160Kbps=HIFI high fidelity (the best setting value for mid-to-high-end MP3 players)

192Kbps=CD (the best setting value for high-end MP3 players)

256Kbps=Studio music studio (for music enthusiasts)
