Move to jack2
Fedora 14 moves from
jack2, formerly called
jack2 offers many improvements over previous versions available in Fedora. Current
jack-capable programs can take advantage of these improvements without modification.
jack2takes advantage of multi-processor or multi-core systems. The result is fewer audio glitches when more than one
jack-enabled program is run.
- You can now modify connections without interrupting the audio stream. This means that you do not need to stop recording or playback in order to change how your programs connect to each other.
- "Asynchronous" activation prevents audible audio glitches. If a program does not provide a sample in time,
jack2automatically repeats the previous sample. The old
jackserver would have produced an audible glitch, but with
jack2, you may not even hear the missing sample.
- You can use
PulseAudioon the same computer. When the
jackserver starts, it automatically takes control of your audio hardware from
PulseAudio. When the
jackserver stops, it automatically returns control of your audio hardware to
PulseAudio. There is no longer a benefit to removing
The move to
jack2 is another example of the behind-the-scenes improvements that are a part of Fedora 14.
New to Fedora14, gtick is a metronome application supporting different meters and speeds up to 1000 bpm. Review the details at http://www.antcom.de/gtick/.
Qsynth is a graphical front-end for the
FluidSynth software-based MIDI synthesizer. Qsynth lets you take advantage of the full capabilities of
FluidSynth more easily. You can change all aspects of a
FluidSynth setup, and even run multiple instances of the
FluidSynth synthesizer, from within one Qsynth window.
Qsynth is explained in Chapter 10, "FluidSynth" of the new Musicians' Guide.
With Fedora 14, the Documentation Project introduces a new user guide about music and audio software.
