n-Track Studio is an audio and MIDI multitrack recorder that turns your computer into a full-fledged recording studio. You can record and playback a virtually unlimited number of audio and MIDI tracks. The program supports simultaneous recording from multiple 16-bit and 24-bit soundcards, and real-time audio effects can be applied non-destructively to each track. Built-in effects include Reverb, Multiband Compression, Chorus, Delay, Pitch Shift, Graphic and Parametric EQ, and spectrum analyzer. The program can use third party VST plug-ins to process audio signals in real-time. Effects can also be used to process the recorded signal in real-time. MIDI tracks can be imported end exported to regular MIDI files, and edited using the built in piano-roll based MIDI editing window. The program supports VSTi instrument plug-ins for sample accurate software MIDI playback. Volume and pan evolution can be programmed by drawing on the timeline window.
Khronosphere is an audio recording tool. Its special feature is a buffer that keeps capturing audio even before the actual recording is started. This enables the user to prospectively catch any interesting sound that normally would have been lost. The buffer size is freely definable by the user. The software itself places no restrictions; the only limits are the resources of the host system. Khronosphere is very similar to and inspired by Jack Time Machine. They both have the same basic concept, but Khronosphere supports larger buffer sizes.
