Information about AIFF

File extension
aiff
File category
Audio
Stands for
Audio Interchange File Format
Developer
Apple Inc.
Overview
AIFF is an uncompressed audio file format. It keeps the original file without losing any data. This is the main reason why these files require more storage space. One minute-long audio requires nearly 10MB space. It is widely used by Apple Macintosh/Apple Mac and also musicians use this format for their recordings. Exact copies of music can be formed using this format with the added benefit of sound quality, which is well maintained in these files. Though it follows lossless format(not compressed), yet, there is another variant of it named AIFF-C developed by Apple afterwards and it is the compressed version. The only disadvantage of these files is a large size.
Technical description
Mostly AIFF files have uncompressed Pulse Code Modulation(PCM) data which means at regular intervals the amplitude of the analog signal is reduced from continuous-time signal to a discrete-time signal and every sample is quantized to the closest value. An AFF file has various parts which are known as chunks and each chunk has its own ID which is mostly termed as FourCC. This ID is a sequel of four bytes which distinctly identify data formats. The several chunks found in this format are Common, Sound data, Marker, Instrument, Comment, Name, Author, Copyright, Annotation, Audio recording, MIDI data, Application, and ID3. The first two chunks are essential every time(Common chunk and Sound data Chunk). Lastly, these files have the capability of storing Metadata in five chunks-Name, author, comment, annotation and copyright. Metadata delivers information about the data that is data about data.

Information about FLAC

File extension
flac
File category
Audio
Stands for
Free Lossless Audio Codec
Developer
Xiph.org
Overview
It 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 description
FLAC 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.
