It's a measure of success that the term "MP3" is probably generally understood to mean "digital audio file." But an MP3 file contains a very specific type of audio compression, and its success, in ...

Lossless data compression of digital audio signals is useful when it is necessary to minimize the storage space or transmission bandwidth of audio data while still maintaining archival quality.

As mentioned previously, the characteristics of typical audio signals vary from time to time and therefore we must expect the required bit rate for lossless compression to vary as well. Since the bit ...

"Lossless" and "lossy" are both types of compression. A zipped file is lossless, because when you unzip it, every original bit is still there from the original file. A JPEG, however, is a "lossy" file ...

The IP surveillance market has boomed over the past decade with dozens, if not hundreds, of new players emerging and traditional CCTV manufacturers expanding into networked technologies. With the ...

A process is used when music is compressed into MP3 to discard all the sounds a machine thinks the human ear can't audibly perceive, thus vastly reducing the amount of storage needed to hold entire ...

There are two types of compression that can be applied to files: With lossless compression, files are reduced in size without the loss of data. However, lossless compression does not usually achieve ...

Apple announced on Mac OS Forge today that they have open sourced their Lossless Audio Codec (ALAC). ALAC was introduced in 2004 as OS X’s core audio codec to compress audio files 40-60 percent ...
