QJackRcd is a simple Qt application that records JACK server outputs. It was designed to record audio from tape, with an automatic split/pause feature. It aims to provide for simple stereo recording needs with a minimum of configuration. It natively manages silence by threshold and activation time. Silence events can be used to pause the recording or to split files. It can optionally post-process each file after recording is complete.
ng-jackspa is a set of simple user interface programs that host a LADSPA plugin, providing JACK ports for its audio inputs and outputs, and dynamic setting of its control inputs through the user interface. Additionally, the plugin controls can be exported to or controlled by control voltages on standard JACK audio ports. The following interfaces are available: an ncurses visual (full screen) interface for the terminal; a GTK+ graphical interface; a Qt 4 graphical interface; and a command line interface for the terminal.
