AIFF Technical Specifications

File extension.aiff
File categoryAudio
Stands forAudio Interchange File Format
DeveloperApple Inc.
OverviewAIFF 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 descriptionMostly 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.

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.
