Beatmatching algorithms
- Freecycle
- Amplitude domain
- Frequency domain
- Aubio
- Complex domain
- Phase based
- Spectral difference
- High frequency content
- Modified Kullback Liebler
- Weighted Kullback Liebler
Audio output
- OSS (Threaded)
- ALSA (Threaded)
- Portaudio (Callback)
- Jack (Callback)
- Automatic detection of the sound layer and connection to JACK ports
Midi input
- Portmidi (Threaded)
- ALSA Sequencer (Threaded)
- Runtime, on the fly, MIDI devices detection
Export options
- Wave
- Midi file
- Auto-assignement of missing notes to locked beatlines
- Akai AKP file with sound slices assigned to MIDI notes
- 16bit, 24bit, even 32bit floating point (future AKAI ?)
- Separated audio slices
- SoundFont2 with separated slices assigned to MIDI notes
Amplitude Envelope
- Applied between two locked beatlines
- Non destructive envelope editing
- Five stages non linear (Bézier) envelope
- Attack (Bézier)
- Hold (Linear)
- Decay (Bézier)
- Sustain (Linear)
- Release (Bézier)
- Envelope duration period controller
- Envelope precision controller (TODO)
- Three end modes for the envelope
- end: After the duration period the envelope is desactivated
- cont: After the duration period the amplitude is maintaned at release (0) or sustain level
- next: The sustain level is maintained until before the next locked beatline, then release gets applied
LADSPA
- Fully integrated LADSPA
- Non destructive LADSPA editing
- Four possible input sources per LADSPA audio input
- From Left channel
- From Right channel
- From Left + Right
- 0 (outputs 0 to LADSPA plugin)
- Four possible output sources from LADSPA audio output
- To Left channel
- To Right channel
- To both channels
- To null (The output from LADSPA is voided)
- Double plugin mode (Usefull for mono plugins when applied to stereo signal)
- Full LADSPA input control ports automation with four edit modes
- point by point
- Line
- Polyline
- Bézier spline
- Hardcoded LADSPA control resolution (evaluated every 1024 frames)
Drag ‘n drop
- Inside Freecycle
- From Freecycle to any Qt drag’n drop enabled application
- Konqueror, Konsole, … (saves the audio file)
- Muse (drops the audio slice)
- Rosegarden (drops the audio slice)
- Freecycle (drops the audio slice between two locked beatlines)
- To Freecycle from any Qt drag ‘n drop enabled application
- Konqueror (imports the wave between two locked beatlines)
- Freecycle (drops the audio slice between two locked beatlines)
- Non destructive, stacked, audio slice drop with the ability to switch between different stacked slices
Scene management
- 8 scene slots with assignable stacked slices
- Switching between scenes switches the stacked audio slices
Spectrogram plotting
- High precision spectrogram output
- Adjustable FFT parameters (Frequency and time domain)
- Rectangular, Hanning and Gauss windows
- Zero or signal padding
- Adjustable lower and upper frequency plot
- Bark scale (24 critical bands of hearing)
MISC
- Intuitive, user and mouse friendly graphical user interface
- Comprehensive, human readable, xml based project saving
- Saves waves,envelope information, stack and scene information, LADSPA automation, locked beatlines and assigned midi notes
- Internal 32bit audio processing
- Open source, GPLed and absolutely FREE application
