Bit rate refers to the amount of binary data per unit of time after converting an analog sound signal to a digital sound signal.<\/p>\n

The higher the bitrate, the better the sound quality (under the same encoding format, different formats cannot be compared). audio bitrate. Bit rate is a benchmark of digital music compression efficiency. Bit rate indicates the rate of the number of bits bps (bit per second, bits per second) transmitted in a unit of time (1 second).<\/p>\n
Kbps (in layman’s terms is 1000 bits per second) is usually used as the unit. The bit rate of digital music on CD is 1411.2 kbps (i.e. to burn 1 second of CD music, 1411.2 \u00d7 1000 data bits are required), the high bit rate of the music file means that the data must be processed in a unit of time (1 second) The amount (BIT) is large, that is, the sound quality of the music file is good.<\/p>\n
However, when the BITRATE is high, the file size increases, which will occupy a large amount of memory capacity. ranges in this sense, most of them are 32-256 Kbps. Of course, the wider the index, the better, but 320 Kbps is the highest level for the moment.<\/p>\n
What do sample rate and bit rate mean in a song?<\/p>\n
Bit rate Bit rate refers to the sampling rate at which digital sound is converted from analog to digital format. The higher the sampling rate, the better the quality of the restored sound.<\/p>\n
The bit rate value is compared with the actual audio: 16 KBPS = phone sound quality 24 KBPS = increase phone sound quality, shortwave transmission, longwave transmission, European standard medium wave transmission 40 KBPS = American Standard Medium Wave Broadcast 56 KBPS = Voice 64 KBPS = Voice Boost (best bitrate for mobile phone ringtones)<\/p>\n
setting value, the best setting value of mobile phone mono MP3 player) 112 KBPS = FM radio stereo FM 128 KBPS = tape (best setting value of mobile phone stereo MP3 player, best setting value of low-end MP3 player) 160KBPS=HIFI HIFI (best setting for mid to high end MP3 players) 192KBPS=CD (best setting for high end MP3 players) 256KBPS=Studio Music Studio (for music enthusiasts )<\/p>\n
Sampling rate is when the analog signal is converted to a digital signal Sampling rate is related to sound quality. The higher the sample rate, the better the high-frequency restoration of the sound file. The following is the different quality corresponding to different sampling rates 1.11,025Hz<\/p>\n
The sound of this sample rate is similar to the sound quality of AM radio 2.22,050Hz The sound of this sample rate is similar to the sound quality of FM radio, but lower than 3.32,000Hz This sample The sound of this frequency is superior to the sound quality of FM 4.44 100 Hz broadcast<\/p>\n
The sound of this sampling rate reaches the sound quality of CD audio 5.48,000Hz The sound of this sampling rate reaches the sound quality of DAT audio 6.96,000Hz<\/p>\n
Sound of this sample rate reaches DAT audio sound quality The higher the DVD audio sound quality sample rate, the larger the disk space occupied by the final sound file. Usually we can choose 44.1KHZ sampling rate.<\/p>\n","protected":false},"excerpt":{"rendered":"
