openMHA 4.5.3 released

openMHA can now be compiled and used under Mac OS X and features an adaptive feedback cancellation algorithm.

The software contains the source code of the openMHA Toolbox library, of the openMHA framework and command line application, and of a selection of algorithm plugins forming a basic hearing aid processing chain featuring
• calibration
• bilateral adaptive differential microphones for noise suppression
• binaural coherence filter for feedback reduction and dereverberation
• multi-band dynamic range compressor for hearing loss compensation
• spatial filtering algorithms:
• a delay-and-sum beamformer
• a MVDR beamformer
• single-channel noise reduction
• simple upsampling and downsampling plugins
• STFT cyclic aliasing prevention
• adaptive feedback cancellation
