OverviewAAC is the descendant of the MP3 format. It provides better sound quality using a similar bit rate as of MP3. Besides this, it uses lossy data compression but it has high standards of audio quality than of MP3. We can find this format on a number of platforms and Apple's iTunes is one such example that uses it as default audio format. Size of its file is much smaller which is approximately one-tenth of MP3 file. It also neglects the redundant information that is not even processed by the human ear and is often not noticed. Although, this format was introduced as MPEG-2 Part-7, yet, standardization was done by ISO/IEC as a part of the MPEG-2 and MPEG-4 families. It is also termed as MPEG-2 NBC (Non- Backward Compatible) because it is incompatible with MPEG-1 audio formats i.e. MP1, MP2, MP3.
Technical descriptionModified discrete cosine transform(MDCT) algorithm is used by AAC which ensures that it provides high compression efficiency. MPEG-2 PART-7 has three default profiles namely Low Complexity (LC), Main Profile (Main) and Scalable Sample Rate (SSR). These profiles come with Perceptual Noise Substitution which enhances coding efficiency and provides excellent audio quality. Furthermore, it uses Auditory Masking to ignore the surplus information. This codec has come up with advanced features which are not available in the predecessor. These include additional sample rates ranging from 8 to 96 kHz, 48 Channels, better efficiency with a simpler filter bank, higher coding efficiency for stationary signals and higher coding accuracy for transient signals.

File categoryAudio
Stands forWaveform Audio File Format
DeveloperMicrosoft and IBM
OverviewWAV or WAVE is an audio format which was developed to store audio files on personal computers. These files include music, spoken or speech audios and sound effects. The size of the files in this codec is very large as it does not use a lossy format like MP3. This is the main reason why this format has lost its popularity. Due to its size, it is hard to transfer files over the internet which had resulted in less acceptance. This format is supported by many programs like a window Media player. Therefore, these audio files can be played using aforesaid software. One can not completely ignore this format as it provides high quality of audios. Due to this, it is used for radio broadcasting.
Technical descriptionThis format supports metadata that is why we can add details using information chunk. Data in this codec is stored in chunks as it is an application of RIFF(Resource interchange file format). Furthermore, LPCM(Linear pulse code modulation) is the most common, uncompressed audio format in this, but it can also store compressed audio like MP3. Also, it is especially used by professionals as LPCM audio format offers a maximum quality. Only files up to 4 GB are supported by this format which is one of the limitations in this format. This is because of 32-bit unsigned integer which carries the file size header. To overcome this, W64 format came into existence which can record long audios as it enables 64-bit header.
