I have compared the recovered audio of both DSD and DSDPlus to several 'real' radios here listening to the same signals, including an XTL5000 and a Tait TM9155 P25 mobile and to my ear, the original DSD more closely matches what the real radios sound like.

To me, DSD sounds much more natural, even though the audio bandwidth is slightly less (0-3.5Khz) compared to DSDPlus (0-4Khz). Interestingly, I don't get the 'Picket Fence' effect with the original DSD when running either VB Audio Cable or VAC and actually, I prefer the original DSD audio anyway as it is nowhere near as harsh to listen to.ĭSDPlus seems to compress the recovered audio to the point where the audio has almost no dynamic range to it. I will check today to see if DSDPlus sounds the same with VAC. I have noticed a similar effect with DSDPlus, but hadn't considered attributing it to VB Audio Cable as I had assumed that this was just another weird characteristic of recovered DSDPlus audio. Note that the link above has wording above the downloads that says: VB-Audio Virtual Cable <<<- This is where you find only one download for the donationware driver - there is technically no free version anymore of this software like in the past, they altered it to strictly donationware as of July 2013. WIth VBCable, each cable is a separate and unique driver, each one is not identical, they have unique IDs hence being able to install them individually.Īlso note the link provided above is not the traditional one, this is: If you try to install just the original one multiple times it doesn't work, obviously, hence having the individual versions.Įven back when the first one was the only one available for a download, when you made a donation they didn't provide you with some 'key' to enable multiple virtual cable functionality - that's not how it works. That's why it's listed 3 times with 3 separate downloads - they are not the same as I've got two of them installed as shown, the original and A and both function. No, it's not, it's three distinct downloads:
