It can also extract audio from the following video extensions: RM, RV, ASF, DivX, MPG, MKV, MPEG, AVI, MOV, OGM, OGV, QT, VCD, SVCD, M4V, NSV, NUV, PSP, SMK, VOB, FLV, WEBM and WMV. Parallel Processing, a CD ripping function with CDDB support, batch conversion, tag preservation for most supported formats, independent tag reading and writing, service menus for KDE Dolphin/Konqueror, a Gnome Nautilus script, and action scripts for Nemo/Thunar are also provided.
Soundboard is a sound cueing program designed for theatrical use. It aims to be simple to use and maintain cross platform compatibility so that a sound designer who uses a Mac can build a show and have it play back on the theatre's Windows-based playback computer. Soundboard provides a cross platform and open source alternative to programs such as QLab and SFX. It is designed to be simple enough for high school students and community theatres to use, and yet robust enough to be a viable application at a regional theatre.
Ecasound is a software package designed for multitrack audio processing. It can be used for simple tasks like audio playback, recording, and format conversions, as well as for multitrack effect processing, mixing, recording and signal recycling. It supports a wide range of audio inputs, outputs, and effect algorithms. Effects and audio objects can be combined in various ways, and their parameters can be controlled by operator objects like oscillators and MIDI-CCs. A versatile console-mode user interface is included in the package.
QjackCtl is a simple Qt application to control the JACK sound server daemon, specifically for the Linux Audio Desktop infrastructure. It is written in C++ around the Qt4 toolkit for X11, most exclusively using Qt Designer. It provides a simple GUI dialog for setting several JACK daemon parameters, which are properly saved between sessions, and a way to control of the status of the audio server daemon. With time, this primordial interface has become richer by including an enhanced patchbay and connection control features.
Qsynth is a GUI front-end application for Fluidsynth. Fluidsynth is a command-line software synthesizer based on the Soundfont specification. Qsynth was built with the Qt4 toolkit using Qt Designer. Eventually it may evolve into a softsynth management application that allows the user to control and manage a variety of command line softsynths, but it currently just wraps the excellent Fluidsynth program.
Freeverb3 is a signal processing library. It includes many types of audio processing effects and signal generators including a linear feedback shift register (LFSR) maximum length sequence (MLS) generator, multiple types of high quality mono+stereo reverb effects, a multi slot impulse response processor, multiband hardknee+softknee compressor and limiter, a stereo enhancer, a limiter, and many types of infinite impulse respose (IIR) and finite impulse response (FIR) filters. Also available is Freeverb3VST, a VST effects plugins package based on the Freeverb3 library.
