MP4(short for MPEG-4 Part 14) is a file format based on ISO/IEC 14496-12:2004 that is based on QuickTime File Format but formally specifies support for Initial Object Descriptors (IOD) and other MPEG features. It is mostly used to store video and audio but can also be used to store subtitles and still images. MP4 files are stored with the .mp4 extension. MP4 is an international audio-visual coding standard. Similar to most modern container formats, MP4 supports streaming over the internet. Due to the high compression used in MP4, the resultant files are smaller in size with almost all the original quality retained.
Read moreThe AIFF (Audio Interchange File Format) is an uncompressed audio file format developed by Apple in 1998, but is based on EA IFF 85 (Standard for Interchange Format Files developed by Electronic Arts), a wrapper format used on Amiga systems. This file format comes up with a standard for storing sampled sounds. The format is good enough in flexibility, and enables the storage of monaural or multichannel sampled sounds at various sample rates and sample widths. Since the AIFF files are uncompressed, this thing making them bigger in size than other lossy formats such as MP3. These files consist of 2 channels of uncompressed stereo audio with 16 bits sample size, recorded at 44.1 khz. Because of high quality of audio, a 5 minute audio can take upto 50MB disk space which is similar to WAV file format.
