Ability to save audio output in both .WAV and .MP3 format.

Ability to choose both your audio input and your audio output

Advanced decoder options are available to allow you to fine tune DSDPlus for a particular site / system / transmitter that you are monitoring.

DSD+ Public Version 1.101 and Fastlane

The latest public release version of the popular digital decoder software is V 1.101. The developer(s) have an accelerated release called Fastlane in which additional features and capability have been added to the program. Fastlane is available for a nominal fee, instructions to join Fastlane follow :

From the DSDPlus.txt file:

DSD+ Fast Lane

Early access to features is being offered through the DSD+ Fast Lane program.

Fast Lane updates are expected to be released about once per month.

Some Fast Lane updates WILL have issues/bugs. That is the nature of alpha software.

Fully tested public releases will continue to be released, approximately every 6 months.

In light of the extra workload the Fast Lane program will create, the DSD+ team is asking Fast Laners for:

US$10 for one year of Fast Lane updates

US$25 for unlimited Fast Lane updates

Donations above these amounts are welcomed, but it's up to you. We're not looking to get rich here. Funds will be used for things like needed hardware upgrades.

Funds can be sent our Paypal account (dsdplusfastlane@gmail.com)

Please include a comment that specifies the email address that your Fast Lane updates should be sent to.

NOTE: IF YOU DO NOT INCLUDE A COMMENT, PAYPAL DOES NOT SEND US A NOTIFICATION. THIS *WILL* DELAY YOUR FIRST FAST LANE UPDATE.

The Public version of the software and updates to the software can be found at the DSDPlus website

The creator asks that any bugs be reported on the Voice Control Channel Decoding Software Forum
