Thetis v2.10.3.11 - Release
Whilst a number of things have been fixed and added since v2.10.3.9 it might be worth watching the highlights of the changes in v2.10.3.9 over on YouTube : WATCH HERE
This release includes two new noise reduction methods, NR3 and NR4. See change log below. Note: There is a specific discord channel to chat about the noise reduction solutions here.
IMPORTANT NOTE: It is worth making a backup of your DB before installing this version. It is also worth un-installing previous Thetis installs using Add/Remove Programs before installing this version.
(Note: Uninstalling via Add/Remove Programs will leave your database intact. You don't need to take any specific action beyond backing it up if required. Thetis will handle the database appropriately.)
Tip: You can always access these release notes through the button in the About box. The full change log is also available there.
If you encounter any issues, please report them on GitHub here.

v2.10.3.11 - Change Log
[add] two new noise reduction methods added, NR3 and NR4. When starting up this version for the first time if NR was enabled, will now be set to off. Only support for nr/nr2 is available through cat and other systems that use cat such as midi. Settings in the normal NR settings page of Setup
NR3 - RNnoise - A noise suppression library based on a recurrent neural network. Latest code here - https://gitlab.xiph.org/xiph/rnnoise . More info here - https://arxiv.org/pdf/1709.08243.pdf
NR4 - SpectrumBleach - libspecbleach - This library is based on the algorithms that were used in noise-repellent. Source here - https://github.com/lucianodato/libspecbleach . More info here - https://github.com/lucianodato/noise-repellent/wiki
[add] cat commands ZZNE and ZZNF (rx1+rx2) added to set/get NR config for each receiver. eg ZZNE; will return 0 if off, or 3 if NR3 selected. ZZNE4; will select NR4
[add] midi commands added to select NR3 NR4
[add] cat commands ZZNG and ZZNH (rx1+rx2) added to set/get NR4 reduction amount as a percentage. eg ZZNG; will return 000 for 0dB, or 100 for 20dB. ZZNG050; will set NR4 reduction to 10dB. Note, must pad to 3 000
[add] midi commands added to assign rx1/rx2 NR4 reduction amount to a knob/slider
[add] override colour for flashing spot
[add] keyword option added to finder. It will split the search by the spaces and treat those as keywords. It will return any entry where all of those keywords exist
[add] CATstructs.xml data added to finder. You can also use the search term 'catcommand' to just return cat commands and especially useful with the keywords option
[change] updated PortAudio from existing Release 19.7.0 to the latest code as of 29/06/25. Version number has not changed. Last commit was 13/06/25 #87e35e7 in the version now used
[change] for new TCI spots without the [json] tag they will always flash for 2 mins if the option is selected. If the spot comes in again and already exists in the display then it will not flash if this 2 min has elapsed
[change] spot time is not updated if another spot arrives with the same data and that spot is currently being displayed

Hi Ritchie,
As always, thanks so much for another fantastic release!
The new NR modes are great.
Have an issue with VAC2 - on my Windows 10 box, it isn't working no matter which driver is used (e.g. MME, Directsound, ASIO) ; even when the driver is set up to be identical to that for VAC1. When VAC2 is enabled there's no sound out, and a constant stream of "TO VAC: (Out)" underflows, with the number rapidly increasing. There's minimal overflows and underflows on "FROM VAC: (In). All of the drivers work and output audio when selected in VAC1.
