Release 2.2 - Py3 ready (October 20th, 2016)

This release fixes some bugs concerning the simulation for acoustic resonators with a single mode, and the estimation of the fundamental frequency (due to changes in Aubio). It also updates the embedded h5pickle module. Last but not least, Moreesc now supports Python3!

Release 2.1 (February 3th, 2013)

This release fixes some bugs concerning the plot of the results (due to changes from Matplotlib 1.11 to 1.12), allows to write wav files even without the scikits.audiolab package.

Release 2.0 (January 7th, 2013)

This release brings a brand new rewrite of the code allowing simulation of transients as slurs, vibratos, and others effects through the ability to define time varying acoustic resonator and reeds (cane reed or lips). Moreover it eases the interpolation between measured input impedances, and the use of measured pressure and/or lip stress via the Profiles objects. Note also that the valve is now not stuck to single d.o.f but may involve several resonances or even none!

Finally new ODE integrators are available allowing to choose the right tool for each case.

Release 1.7 - Buzzing version (April 24th, 2010)

Lip damping is now controllable too.

Release 1.6 - Buzzing version (February 27th, 2010)

Special version for vibrating lips!
In this release, valve has an outwards behaviour intended to model lip valve for brass instruments. Moreover, in order to mimic real playing, lip natural frequency (only one by now) is a time varying function.

Release 1.5 Not distributed (internal to the lab).


Release 1.4 - SingleReed version (June 18th, 2009)

Acoustic Resonator
- Added functions to convert pole/residue couple to/from resonance frequency/quality factor/peak value tuple.
- Performing the computation of the supplementary pole linked to the reed motion induced terminal condition is now available.
- Modal decomposition of an experimental input impedance is now done using the procedure suggested by LeRoux & Herzog.
- Physical constants (as the density, the wave speed, the visco-thermal boundary layers thicknesses) are now possibly adjusted according to the temperature.
Solver
- The initial conditions corresponding to the static regime (even instable) are checked using AUTO (thanks to Sami Karkar)
- Computation of the instantaneous frequency of the pressure signal.
- Once an auto-oscillation has been calculated, it is possible to store the configuration and the results to restore it later.
- Alpha stage : a method to prolongate a simulation on an extended time interval
Installation:
We are know able to install from sources or from the binary installer on windows platform.
Bug fixing:
- Docstrings are now readable (unicode fixed)
- Fixed minor bugs in the SimulationTemporelle methods (condition_initiales, grandeurs_controle).
