Audio Bitrate: What is the Bitrate of Music Part 2
What do sample rate and bit rate mean in a song?
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. 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 transmission 56 KBPS = voice 64 KBPS = voice boost (best bit rate for mobile phone ringtones) Setting value, the best mobile phone mono MP3 player setting value) 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 MP3 players mid- to high-end) 192KBPS=CD (best setting for high-end MP3 players) 256KBPS=Studio Music Studio (for music enthusiasts) The sample rate is when the analog signal is ca is converted to a digital signal The sampling rate is related to the quality of the sound. 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 The sound of this sampling rate is similar to the sound quality of AM radio 2.22,050Hz The sound of this sampling rate is similar to the sound quality of FM radio, but less than 3.32 000 Hz This sample The sound of this frequency is higher than the sound quality of FM broadcast 4.44 100 Hz The sound of this sampling frequency reaches the sound quality of the CD audio 5.48000 Hz Sound at this sampling rate reaches DAT audio sound quality 6.96000 Hz Sound at this sampling rate reaches DAT audio sound quality The higher the sampling rate sound quality of the DVD audio, the more disk space the final sound file will take up. Usually we can choose 44.1KHZ sampling rate.
