Re: How to start openMHA

Hi Kristin, it seems that the entry for openMHA is missing in your PATH environment variable. Please check in your system settings whether the entry is there. The error message occurs, because mha does not find the configuration file to be read, as it is not in the same directory in which you starte...

Re: Beamforming and dereverbaration

In your example 36 is the correct choice.

Re: STMicroelectronics boards

Hi fam, the use of openMHA under the AGPL-3.0 is possible for a company, but of course with all consequences implied by this open-source license. In particular, the complete source code of work that incorporates openMHA must be made available under the same license. Please see the license text for d...

Re: Question regarding gain table

Hi Shaikath, in case you're referring to the peaklevel values set in the transducers plugin: These values don't influence the gaintable itself. If the input level is below or above the range that the user has specified by the number of entries in gtdata in combination gtmin and gtstep, the gainable ...

Re: Gain Table

Hi, to apply a gain of 20dB at your 500Hz band for both input channels and for all input levels - in addition to the +20dB @4kHz, 1st channel and +10dB @4kHz, 2nd channel - you have to set gtdata to [[0 0 0];[20 20 20];[0 0 0];[0 0 0];[20 20 20];[0 0 0];[0 0 0];[20 20 20];[0 0 0];[0 0 0];[10 10 10];...

Re: Beamforming and dereverbaration

Unfortunately, we don't have a proper script at hand at the moment and I'm aware that we need to provide one in the future. The computation of the MVDR beamformer from head-related transfer functions is described in this contribution presented at the ITG Conference on Speech Communication 2016: www....
