Monkey's Audio

Monkey's Audio is an algorithm and file format for lossless audio data compression. Monkey's Audio does not discard data during the process of encoding, unlike lossy compression methods such as AAC, MP3, Vorbis and Musepack.

Data file compression is employed in order to reduce bandwidth, file transfer time, or storage requirements. A digital recording (such as a CD) encoded to the Monkey's Audio format can be decompressed into an identical copy of the original audio data. As with the FLAC and Apple Lossless format, files encoded to Monkey's Audio are typically reduced to about half of the original size, with data transfer rates and bandwidth requirements being reduced accordingly.

Monkey's Audio's advantages are better compression rates compared to FLAC and WavPack, as well as multithreading/multicore support. Monkey's Audio main drawbacks are the fact that it employs a symmetric algorithm, meaning the decoding takes comparable resources to encoding, which makes it unsuitable for all but the fastest portable players (via Rockbox firmware), and that it has limited support on software platforms other than Windows; on other platforms only decoding is officially supported by third-party programs. Although the original source code is freely available, the license is not considered to be an open source one. A GPL version of the decoder has been independently written for Rockbox and then included in ffmpeg.

3APL

An Abstract Agent Programming Language or Artificial Autonomous Agents Programming Language or 3APL (pronounced triple-A-P-L) is an experimental tool and programming language for the development, implementation and testing of multiple cognitive agents using the Belief-Desire-Intention (BDI) approach.

Overview

3APL was developed and is maintained by a team at the computer science department of the University of Utrecht in the Netherlands. It facilitates specification of cognitive agent behavior using actions, beliefs, goals, plans, and rules. It has been subject to at least 15 papers and conferences, and at least 4 theses.

Platform

The 3APL platform has a visual interface for the monitoring and debugging of agents being run therein, and a syntax-coloring editor for source code editing. It has been released as a Java-based software, which comes with some specification Java interfaces that can be used to develop Java-based plug-ins and libraries. These can be used to provide a visible representation of a virtual environment, for instance. A 3APL platform can also connect in client or server roles to other 3APL platforms across a network, to allow communication among 3APL agents on each platform. A lightweight version of 3APL for mobile applications, named 3APL-M "Toymaker", has also been released.
