openMHA 4.9.0 available
Release 4.9.0 of openMHA contains several new plugins, features, improved documentation and bug fixes.
- delaysum_spec: realizes sub-sample delay
- mconv: partitioned convolution
- fftfilter: FFT-based FIR filter
An optional interactive mode has been added to the openMHA executable such that inputs can be passed directly in the terminal running the mha executable.
Checks of overlap-add configurations were implemented to ensure preservation of amplitude under the transformation.
Improved documentation of openMHA plugins of the prediction_error plugin
and the split plugin.
The plugins that implement single-channel noise reduction (formerly known as noisePowProposed and timoSmooth) are renamed to noise_psd_estimator and smooth_cepstrum and plugin documentation has been extended.
For consistency and due to the frequency-domain implementation delaysum_spec the delaysum plugin has been renamed to delaysum_wave.
Bug fixes (also with thanks also to user reports on Github):
- Matlab gui becoming non-responsive on error
- wrong handling of DC and Nyquist bin in FFTs
- thread-safety of wavrec
- crash in acPooling_wave
- webcam handling in example 09
