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. |

Overview |
| AAC 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 description |
| Modified 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. |
