FLAC Technical Specifications

File extension.flac
File categoryAudio
Stands forFree Lossless Audio Codec
DeveloperXiph.org
OverviewIt is an audio format which uses a lossless compression technique to compress the original data, without any loss of information. The additional benefit of this format is it maintains a very good quality of Audio. These files are encoded using FLAC algorithm that reduces the size of the primary file ranging from 50 to 80 per cent as the size varies according to the amount and density of the data. Therefore, this codec helps in the production of exact replicas of original data but in reduced size. It also supports a number of electronic devices. For instance- Portable players, car stereos etc. As well as it is streamable which allows users to jump to the middle of a stream with minimum delay.
Technical descriptionFLAC can deal with any channels from 1 to 8. It also supports PCM bit resolution up to 32 bits per sample and any sampling rate up to 655,350Hz in a single Hertz increment. REPLAYGAIN is an added feature in it which helps to measure and normalize the loudness of received audio. Moreover, it can deflate audio at very high speed which makes it to stand out from the other formats. Also, it is an open-source software which means original source code is freely available and it may be modified as per user’s requirements. Lastly, it has flexibility in metadata that allows one to write its own application when it is registered ID. Its metadata includes tags, cover art, seek tables and cue sheets.

MP3 Technical Specifications

File extension.mp3
File categoryAudio
Stands forMPEG Audio Layer-3
DeveloperFraunhofer- Gesellschaft (A German research institute)
OverviewIt is a digital Audio which compresses the tracks using the lossy format. Although, it follows the lossy format, yet, there will be no noticeable change in the quality of audio. It only discards the superfluous information that a human ear is inefficient to process or hear. With the help of the this extension, one can upload and download audio files with ease, irrespective of the internet connection speed even a dial-up connection users can access these files. There are a number of MP3 Blogs(music blogs) available on the internet where maker uploads music files and a user can download the same without any trouble. These blogs help people to get an insight into the music world. Hype Machine is an example of an audio blog.
Technical descriptionMP3 uses lossy data compression, which means when data is encoded it is not the full original version, it’s a substitute to original copy but in a smaller size. This compression can lead to a decrease in file size, ranging from 75% to 95%. This format is based on perceptual coding due to which this extension screens out the noise, and results in an audio file that uses a low bit rate(lowest bit rate in it is 128kbps). It provides audio of fair sound quality. As it is only an audio file, thereby, if there are any images linked to it then they need to be stored in a separate file.
