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.

WMV Technical Specifications

File categoryVideo

DeveloperMicrosoft
OverviewIt is a video format based on the Microsoft Advanced systems format(ASF) and it is a sequel of video codecs. There are three varied codecs for this format. Actual WMA compression technique was developed only for internet streaming applications and it gave tough competition to RealVideo. The other compression techniques include WMV screen and WMV image which are designed for specialized content. These files are compatible with both Mac and Personal computers ;etc. This format attracts companies those want to sell audios and videos online due to DRM technology. This is the most popular among its family members. Interlaced videos can also be played using this video extension. There is an advanced version named WMA 9 which automatically comes into play when video resolution exceeds 300,000 pixels and the bitrate 1000 kbit/sec.
Technical descriptionIt is based on DRM(Direct Rights Management), thereby, it restricts users from making unauthorized copies that are often bought online from stores. HD DVD and Blu-ray Disc are formats for physical delivery which were adapted when WMV version was standardized by the SMPTE(Society of Motion picture and Television Engineers). It is now termed as VC-1. MPEG-4 AVC, AVS and MPEG-4 ASP are other competitors against this format. Furthermore, it can also provide support to the variable bit rate, average bit rate and constant bit rate. It enables makers to use non-square pixels as well. Lastly, it can process videos using frame interpolation in which intermediate animation frames are created between the existing frames.
