Re: Control Frequency Shifter using Octave/Matlab GUI
Hi :)
I checked out the examples but a problem arised when I tried to follow the instructions in the „Control Frequency Shifter using Octave/ Matlab GUI“ example (chapter 5).
File editing works, a connection to Jack Server is there and my microfone available. Nevertheless giving the command „mha_query(openmha, ‘ ‘, 'read:fshift_hilbert_live.cfg');“ leads to a crash in octave/matlab.
Have you any idea what’s the problem?
(see file)
Thanks in advance!

Re: Control Frequency Shifter using Octave/Matlab GUI
This can be caused by
- The Windows firewall. MHA allocates a TCP port for incoming connections. To investigate if the Windows firewall is responsible for your problem, the quickest way is to temporarily switch it off completely. If this solves the problem, switch it back on and fine-tune the firewall to allow incoming network traffic to the MHA executable in trusted networks.
- A mix of openMHA components from different versions. Uninstall openMHA with Add/Remove Programs, then make sure all openMHA components are actually deleted from your hard disk, then reinstall.

Thanks a lot!
Indeed the error was caused by the Windows firewall.
