improved WhiteNoise audio effect
added sample based AudioInterference effect
added interference effect to test_config file
added pause/play feature to AudioSample in order to allow a play/pause playback that is not based on a WebAudio implementation bug
Main: hand statics configuration to Mixer
The receiver now sums the tuning values from each station and returns it. This allows the Mixer to react to the overall Tuning value and add static noise etc.
fixed: let a station return it's tuning value after onTune got called
the AudioMixer now adds a Volume FadeIn / FadeOut when a station gets attached. Therefore each station has an additional output gain node to control the volume changes. The station now also uses the play/pause functionality of its AudioSample as the AudioNodeSubtree doesn't get disconnected from the main tree anymore when an unLoad event appears.
added static noise implementation to the AudioMixer. Each file gets loaded and it's volume is controlled (scaled by 0.4) by a sine-oscillator with a random frequency between 0 and 1.
