A multi-channel MPEG encoder, using the ISO13818 standard and the dist10 source code. Multi-channel files may have up to 6 defined channels: Left(L), Right(R), Center(C), Left Surround (LS), Right Surround (RS) and a Low Frequency Enhancement channel (LFE). ISO13818 defines 5 multi-channel modes (on top of the normal stereo mode), each of these modes may have an optional LFE channel: 3/2: L, R, C, LS, RS 3/1: L, R, C, mono surround 2/2: L, R, LS, RS 2/1: L, R, mono surround 3/0: L, R, C The "standard" surround sound encoding of "5.1 channels" is achieved by using mode 3/2 plus an LFE channel. A multi-channel MPEG file should decode OK on any MPEG decoder. If the decoder doesn't recognize the multi-channel extensions, then you'll just get a stereo file containing a down mix of the 5 channels.

Mp3stat is a utility to read information about MP3's and OGG's bitstream. More specifically, how certain bitrates have been placed in the bitstream by the encoder. Not only does mp3stat give you a graphical representation of the average bitrate per 1/500th of the file in, a linear bar graph to allow you to compare encoders and settings, it also has a batch file mode. The batch file mode allows you to use mp3stat as a script utility instead of GUI, for use in your own programs and or scripts. The batch mode can be extended trivially to give just as much info as the GUI version, but now defaults to configurable output of 3 pieces of info; name, runtime, and average bitrate. The batch mode can take MP3's, and OGG's in the same directory, but it cannot (yet at least) recursively run into subdirectories -- this will be possible in the next version, arriving soon.

mpg321 is a clone of the popular mpg123 command-line mp3 player. It should function as a drop-in replacement for mpg123 in many cases. While some of the functionality of mpg123 is not yet implemented, mpg321 should function properly in most cases for most people, such as for frontends such as gqmpeg. mpg321 is based on the mad MPEG audio decoding library. It therefore is highly accurate, and also uses only fixed-point calculation, making it more efficient on machines without a floating-point unit. While mpg321 is not as fast as the non-free mpg123 on systems which have a floating point unit, it comes under the GNU General Public License, which allows greater freedom to its users. For most people who want mpg123, mpg321 is a better alternative.

SDL_sound is a library that handles the decoding of several popular sound file formats, such as raw, wav, mp3, flac, ogg, voc, shn, aiff, au, and some others. It is meant to make the programmer's sound playback tasks simpler. The programmer gives SDL_sound a filename, or feeds it data directly from one of many sources, and then reads the decoded waveform data back at her leisure. If resource constraints are a concern, SDL_sound can process sound data in programmer-specified blocks. Alternately, SDL_sound can decode a whole sound file and hand back a single pointer to the whole waveform. SDL_sound can also handle sample rate, audio format, and channel conversion on-the-fly and behind-the-scenes, if the programmer desires.

wavbreaker is a tool to take a wave file and break it up into multiple wave files. It makes a clean break at the correct position to burn the files to an audio CD without any dead space between the tracks. It will only read wave files, so use an appropriate tool to convert Ogg, MP3, etc. files and then break them up. The GUI displays a summary of the entire wave file being worked on at the top. There is also a command line tool to merge wave files together (wavmerge). This tool will only work on files that are alike. For example, 44100 khz sample rate, 16-bit sample size, etc. (use sox to convert files first if necessary).

Xcd is a simple GUI to control a CD player. It requires Tcl/Tk to be installed on your system. Xcd has the usual buttons to control a CD player: "play", "pause/resume", "stop", "eject", "next track", "previous track", "rewind", "forward" and a volume slider. Xcd displays continuously the current track number and the elapsed time of the track. Pressing the left mouse button on the "track" label causes Xcd to display the total number of the tracks and the total duration of the disk. Pressing the left mouse button on the "time" label causes xcd to display the duration of the current track. Pressing the middle mouse button on the "track" button allows to choose a track number to play.

Icarus Verilog is a Verilog simulation and synthesis tool. It operates as a compiler, compiling source code written in Verilog (IEEE-1364) into some target format. For batch simulation, the compiler can generate C++ code that is compiled and linked with a run time library (called "vvm") then executed as a command to run the simulation. For synthesis, the compiler generates netlists in the desired format. The compiler proper is intended to parse and elaborate design descriptions written to the IEEE standard IEEE Std 1364-2000. The standard proper is due to be release towards the middle of the year 2000. This is a fairly large and complex standard, so it will take some time for it to get there, but that's the goal.

LinPsk is a program for operating on digital modes running on Linux. LinPsk supports BPSK , QPSK and RTTY at the moment. Main features are: the simultaneuos decoding of up to four channels. The different digital modes may be mixed You can define a trigger on each channel to be notified if a text of your choice is detected. You can log each received channel at a file. For easy qso'ing you can define macros and for larger texts to be send you can use two files. You can view the signal as spectrum or in a waterfall display. Both are scalable in the frequency domain. At the Moment RTTY only supports 45 baud and 1.5 stopbits.

JSON (JavaScript Object Notation, http://json.org) is a lightweight data-interchange format. It is easy for humans to read and write. It is easy for machines to parse and generate. It is based on a subset of the JavaScript Programming Language, Standard ECMA-262 3rd Edition - December 1999.JSON is a text format that is completely language independent but uses conventions that are familiar to programmers of the C-family of languages, including C, C++, C#, Java, JavaScript, Perl, TCL, and many others. These properties make JSON an ideal data-interchange language. This package provides a simple encoder and decoder for JSON notation. It is intended for use with client-side Javascript applications that make use of HTTPRequest to perform server communication functions - data can be encoded into JSON notation for use in a client-side javascript, or decoded from incoming Javascript requests. JSON format is native to Javascript,and can be directly eval()'ed with no further parsing overhead.
