Convert FLAC to AAC

A free codec developed for lossless compression of audio content that does not exclude information from the stream. It allows for listening to musical compositions with professional sound reproduction systems, as well as for track archiving. FLAC files are being played by portative audio players, supplied by the most of specialized programs, and are represented in huge variety of hardware implementations. They allow users to copy CD tracks without deterioration in sound quality.

Since streaming is being coded with an increased speed, FLAC files are often less than half of the original track. However, this does not affect the track quality, and therefore the format is popular for online translations and real-time coding. FLAC can support samples with a static point within the range of 4-32 bit per sample and sampling frequency of 655.3 KHz. If new fields arrive, decoders are not being affected.

In order to change FLAC format, one may use Sound Forge or Adobe Audition. In addition to that, some smartphones can easily work with such files.

A proprietary format with lossy compression, which have been created as an alternative for MP3 with a higher quality of coding. Overtones out of human perception are being removed. AAC is two times less than MP3, which means 1/10 of CD digital data.

The format has being widely used since 1997 as the seventh release of MPEG-2 family. As it is supplied by hardware players, the format is highly demanded by music fans. It has been widely spread in Apple production and is being used by default in iTunes.

The format conception is similar to MP3, but it is more advanced. Being able to execute larger compression, it is represented as a separate segment of MPEG-4 standard which is used for creation of compact audio files. AAC is highly efficient with variable and continuous bitrate, with sampling frequency of 8-96 KHz.

The current version complies with the standard of ISO/IEC 14496-3. Compression is performed on the basis of auditory masking effect that provides with data reduction with no deterioration for sound quality.
