So objectively speaking, there’s less audio there for your ear to interpret. When a song is compressed, an algorithm removes bits from the track that it believes the human ear can’t pick up, which reduces the overall file size. High-fidelity or lossless audio has a significantly higher bitrate of 1,411 kbps. Up until now, Spotify has compressed audio down to a bitrate of 160 kbps on desktop or 96 kbps on mobile devices - Spotify calls this rate “normal.” Paid subscribers also have a “high quality” option of 320 kbps audio on desktop. Though a Spotify spokesperson declined to confirm the existence of the new tier, the move would not be unexpected streaming service competitor Tidal already offers high-fidelity streaming for $19.99 a month. Spotted by Reddit users and confirmed to The Verge by a source inside Spotify, the new tier, currently dubbed Spotify Hi-Fi, will cost an additional $5 to $10 a month on top of the service’s $10 monthly price for its premium ad-free streaming service. I've done the test with classical (mozart's requiem, great amount of vocals and harmonies), black metal (thorns, very high pitch and dense sound) & even some freakishly rich experimental indie stuff like Múm (specially their album «Yesterday Was Dramatic - Today is ok»)įinally, for both 320 and 128kbps it'll never equal the quality of CD, played with a HiFi system.In March, Spotify briefly A/B tested a new lossless audio version of its streaming service. To be more precise, if you have an iPod or any mp3 player, and that you have normal average headsets, you wont hear the difference, + it'll save you space. I can say with confidence that i have a very good ear, and i honestly dont hear the difference between both. Lower Bit Rate > Less Bits/Seconds > Less Sound Information > Lower Sound Quality > Lesser Storage Space Higher Bit Rate > More Bits/Seconds > More Sound Information > Higher Sound Quality > Greater Storage Space If you have mobile device with greater storage or expandable memory, so nothing to worry to use MP3 files with higher bit rate. If you have larger storage device like hard disk drives, then I would recommend to enjoy the sound quality with 320 kbps MP3 files, however for limited storage device like MP3 compatible mobile phones, I would recommend to go for lower bit rate MP3 files. Likewise, using a higher bit rate outputs a higher quality audio, but also results in a larger file.įiles encoded with a lower bit rate will generally play back at a lower quality. Using a lower bit rate provides a relatively lower audio quality and produces a smaller file size. Typically, the creator is allowed to set a bit rate, which specifies how many kilobits the file may use per second of audio. When performing lossy audio encoding (compression process), such as creating an MP3 file, there is a trade-off between the amount of space used and the sound quality of the result. The bit rate is quantified using the bits per second ( bit/s or bps) unit, often in conjunction with an SI prefix such as kilo- (kbit/s or kbps), mega- (Mbit/s or Mbps), giga- (Gbit/s or Gbps) or tera- (Tbit/s or Tbps).Įffects of bit rate on space and audio quality In telecommunications and computing, bitrate (sometimes written bit rate, data rate or as a variable Ror fb) is the number of bits that are conveyed or processed per unit of time. It uses psycho-acoustic models to discard or reduce precision of components less audible to human hearing, and then records the remaining information in an efficient manner. This method is commonly referred to as perceptual coding.

The compression works by reducing accuracy of certain parts of sound that are deemed beyond the auditory resolution ability of most people. An MP3 file can also be constructed at higher or lower bit rates, with higher or lower resulting quality. An MP3 file that is created using the setting of 128 kbit/s will result in a file that is about 11 times smaller than the CD file created from the original audio source. The use in MP3 of a lossy compression algorithm is designed to greatly reduce the amount of data required to represent the audio recording and still sound like a faithful reproduction of the original uncompressed audio for most listeners. It is a common audio format for consumer audio storage, as well as a de facto standard of digital audio compression for the transfer and playback of music on digital audio players. MPEG-1 Audio Layer 3, more commonly referred to as MP3, is a patented digital audio encoding format using a form of lossy data compression.
