DSD+ Fast lane Mono audio possible?

[saioke]

I know this is a first world problem and likely unpopular opinion but, would it be at all possible to make all incoming DMR calls mono? I wear headphones a lot and hearing one voice in only one ear is a bit jarring. Recording audio using the "Per-calling" feature under the Output option will record them in mono but it would be nice to have an option for DMR to just always be mono.

What if both slots are in use? You want to hear only one transmission? Might work if one could be sure that entire conversations stayed in the same slot (not possible with trunking) and that the slots always go to the same stereo channels. That last bit might be doable, but I wouldn't know how to code it myself. I leave it to the developer(s) to advise on it.

I couldn't vouch for that, it seems all transmissions in my area come out of one slot. But, there's no trunked DMR in my area either. I do know SDRTrunk supports mono audio for DMR, but I'm not a fan of the UI or the way SDRTrunk functions. I was hoping the feature already existed in DSD+ and that I was just an idiot that didn't know how to turn it on. Regardless, if it's possible or if it isn't, I wouldn't want to be a burden to the devs and ask them to implement a feature nobody else would likely use lol.

You can do this quite simply with a virtual audio cable, plenty of options.

I do the opposite. I run a few instances of DSDplus and output each to their own channel. I then split the audio so some are in the left channel and some in the right, for use with speakers at my desk or streaming to phone/earphones.

I believe I found a simpler way. On Windows 11, you can right-click the speaker icon, then sound settings. There will be an option under "volume" to combine all audio to mono. This method can be annoying though because well, it makes ALL audio on the system mono, which isn't ideal when I use the same system as my daily driver. I watch videos, etc while DSD does its thing on another screen. I think this method would be perfect if I dedicated a PC to the SDR but I'd like to find a system that doesn't draw a lot of power.

I might try your method for now. How easy is it to set up virtual audio cables?

Probably not a helpful answer but... for one channel, DSD-FME does put the audio into both left and right (reverting to the same as DSD when there's two timeslots in use).

Quite easy. VB-Audio has a variety of complexity levels. You should be able to just install VB audio cable. It will show up in your windows audio settings. In DSD you point your audio output to the VAC input. VAC output can be controlled in the windows audio mixer, and you should be able to set the VAC to mono as you have now discovered for your other audio.

Let's not confuse people. VB Cable is one application. Virtual Audio Cable (VAC) is another.

 

[dave3825]

Dave is correct. Both programs are virtual audio cables, with VB Cable being one and Virtual Audio Cable being the other.


Virtual Audio Cable Virtual Audio Cable (VAC) - connect audio applications, route and mix sounds

VB - Cable VB-Audio Virtual Apps

 

[saioke]

Ah I didn't know there was a difference, so those two programs act the same but, VAC can mix sounds together?

Sure, good distinction. Both applications enable the OP to do what they wish to do. And also help to build on the discovery that the OP made with setting Windows audio devices to mono or stereo.

Do you have any other pointers to help OP with their question?
