The term quality is widely used.
\nIn multimedia technology, quality is often used to judge the effect of audio, and quality here is actually bitrate.
\nOn WINDOWS it is called “bit rate” and on some players it is described as ” bit rate “.
\nQuality refers to the bit rate at which digital sound is converted from analog to digital format. The higher the bitrate, the better the quality of the restored sound.

\n16 Kbps = phone quality
\n24 Kbps = increase phone quality, shortwave transmission, longwave transmission, European standard medium wave transmission
\n40 Kbps = American standard medium wave transmission
\n56Kbps=Voice
\n64 Kbps = boost voice (best bitrate setting for cell phone ringtones, best setting for cell phone mono MP3 players)
\n112 Kbps = FM stereo broadcast FM 128 Kbps = tape (best setting value for mobile phone stereo MP3 player, best setting value for low-end MP3 player)
\n160 Kbps = HIFI high fidelity (best setting for mid to high end MP3 players)
\n192Kbps=CD (best setting for high-end MP3 players)
\n256Kbps=Studio Music Studio (for music enthusiasts)
\nIn fact, with the advancement of technology, the quality of music is also getting higher and higher, the highest quality of MP3 is 320Kbps, but some formats can achieve higher sound quality.
\nFor example, the emerging APE audio format can provide real audiophile-level lossless sound quality and smaller volume than WAV format, and its quality is usually 550kbps-950kbps.
\nencoding modeedit stream
\nVBR dynamic bit rate (variable bit rate) means there is no fixed bit rate. The compression software immediately determines which bitrate to use based on the audio data being compressed. This is a method that takes quality as a premise and takes file size into account The recommended encoding mode;
\nABR Average Bit Rate (Average Bit Rate) is an interpolation parameter of VBR. LAME created this encoding mode in response to the low file volume ratio of CBR and the variable size of files generated by VBR. Within the specified file size, ABR takes every 50 frames (about 1 second for 30 frames) as a segment. High-frequency and insensitive frequencies use relatively low traffic, and low-frequency and large dynamic performance use high traffic, which can be used as VBR and CBR, a compromise option.
\nCBR (constant bitrate), constant bitrate means the file has one bitrate from start to finish. Compared to VBR and ABR, the compressed file size is very large and the sound quality will not improve significantly compared to VBR and ABR.<\/p>\n","protected":false},"excerpt":{"rendered":"
