Dolby Pulse is a proprietary audio compression scheme based upon the AAC (Advanced Audio Coding) industry standard, and incorporates additional meta data for broadcast applications.
When compressed data that is subsequently decompressed does not exactly match the original, yet it is considered close enough to the original to be usable, that algorithm is called a lossy compression. Contrast that with lossless compression, where the decompressed version exactly matches the original. Lossy compression is useful in audio and video, where exactness is not critical, while lossless compression is useful in data streams that must be preserved exactly. The lossy compression algorithm often results in more compact compressed results.

File compression uses software algorithms to reduce file size by reducing the bit-rate of a file. Lossy compression takes it a bit further and lowers the quality of thr file to make it even smaller. Lossy compression is commonly used for media files, but would not be appropriate for other types of files.

Advanced Audio Coding is a compression & encoding scheme for Audio formats.
Data Compression is a technique to minimize the space used by data in storing. So when we do compression of data, no data is loss.

There are some basic principles of data compression. They include advantages, disadvantages, and the history of compression. Types of compression include BZip2 and LZMA.
