What do kbps and khz mean in music?

Kbps in music is the transmission rate of digital signals; khz is frequency.

k Every song is ripped from a CD, converted into a WAV file, and then converted to MP3 using software such as Lame. So it must be a sampling rate of 44100Hz. Unless yours is not a song, but you recorded it yourself as a WAV file, and selected another sampling rate when recording.

Kilahertz: Kilohertz, the abbreviation is kHz or KHZ*, it is the unit of alternating current (AC) or electromagnetic wave (EM) frequency, equal to 1000 Hertz (1000Hz). This unit is also used in the measurement and description of signal bandwidth.

Kbps can also represent the transmission speed of the network. In order to intuitively show that the transmission speed of the network is faster, most companies use kb (thousand bits) to express it. If it is kBps with a capital B, it means how many kilobytes are transferred per second. 1kByte/s=8kbit/s (generally abbreviated as 1kB/s=8kb/s).

Extended information:

The popular understanding of kbps bit rate is the sampling rate. The greater the sampling rate per unit time, the higher the accuracy, and the closer the processed file is to the original file. , but the file volume is directly proportional to the sampling rate;

So almost all encoding formats focus on how to use the lowest bit rate to achieve the least distortion. The cbr (fixed code) derived around this core rate) and vbr (variable bit rate), both have been written in this regard, but things are not absolute;

From the perspective of audio, the higher the bit rate, the greater the compression ratio. Small, the smaller the sound quality loss, the closer the sound quality is to the sound source. Similar units include megabits per second (also known as megabits per second, Mbps) and Gbps (commonly known as gigabit).
