The FreeBSD Ports Collection contains well over 10,000 ports, and there's a lot of software that isn't included. Clearly I can't evaluate it all. On this page I'm keeping a list of programs that look interesting and that I might get round to looking at some day.
If you know these packages and have some comments about them, I'd like to hear from you.
XAnalyser is a program to analyse a stereo audio signal. It has two displays: Frequency Spectrum
Using Fast Fourier Transform, the time domain of the signal is transformed into the frequency domain, i.e. the amplitude (in logarithmic scale) of the audio signal is plotted versus the frequency. Either the sum of the left and right channel of the audio signal can be shown or both channels simultaneously.XY Scope
Roughly speaking, the audio signal of left channel deflects a point horizontally and the right channel vertically (just as the beam of a CRT would do). Thus, an audio signal only present on the left channel produces a horizontal line, whereas an audio signal only present on the right channel produces a vertical line. A mono signal produces a 45 degree line. A stereo signal creates a wilde pattern (if the phase is correct, predominately in the same direction as a mono signal) or may even fill the entire scope.
Synergy lets you easily share a single mouse and keyboard between multiple computers with different operating systems, each with its own display, without special hardware. It's intended for users with multiple computers on their desk since each system uses its own display.
Freevo is an open-source digital video jukebox (PVR, DVR) based on Linux in addition to a number of open-source audio/video tools. MPlayer is used to play audio and video files. MPlayer is an excellent media player that can play most popular file formats. Freevo can be used both for a standalone PVR computer with a TV+remote, as well as on a regular desktop computer using the monitor and keyboard.Freevo is easy to download and install for new users. Most hardware is supported (graphic boards, sound cards and video capture devices).
The Freevo core is under heavy development. It is mostly written in the Python programming language which is very well suited for high-level control applications like Freevo.
