DSD is a popular software tool for decoding various unencrypted digital radio protocols about which we’ve previously posted. We noticed that there is now a release of DSD which purports to be capable of decoding the amateur radio digital protocol known as D-Star. This is in addition to P25, X2-TDMA, ProVoice and NXDN offered in previous releases.
According to the author’s, “DSD should easily compile on any Linux or *BSD system with gcc. There are some debugging/development options in config.h that normal users will want to leave disabled as they can severely impact performance. DSD is able to decode several digital voice formats from discriminator tap audio and synthesize the decoded speech. Speech synthesis requires mbelib, which is a separate package.”
More information and code downloads can be found on the DSD GitHub page.
