RouteStar DSD software provides routing solutions with mobile apps and QuickBooks sync. By using this software, you can increase customer satisfaction and productivity by streamlining business processes with the leading route sales and delivery software. Normally Mac OSX handles DSD through DoP. Therefore your DAC has to be capable of DSD512 to do DSD256 under OSX - like for example with IFI DAC. However, ExaSound DAC uses its own special driver under OSX and it is capable of DSD256 on Mac. Which DAC do you have? The first Mac OS music server / audio player software (May 2011) to directly play DSD format (dsf / dff, 64Fs and 128Fs) audio files with any DAC (real-time conversion to PCM during playback) Support for Direct DSD streaming without PCM conversion.

Overview
Digital Speech Decoder is an open source software package that decodes severaldigital speech formats. It uses the mbelib library (a separate open source package)to synthesize the decoded digital speech. It does not allow decoding of encryptedcommunications. It can save the compressed digital audio bits to 'mbe' data files(.imb and .amb extensions) and play back those saved files. It's discussed in this forum.
The latest version (1.6) supports the following formats and modulation types:
- P25 Phase 1
- ProVoice EDACS Digital voice
- X2-TDMA - Motorola public safety TDMA system with P25 style signaling (mostly based on DMR)
- DMR/MOTOTRBO - Digital Mobile Radio standard
- NXDN - 9600 baud (12.5 kHz) NEXEDGE and 4800 baud (6.25 kHz) NEXEDGE/IDAS
- D-STAR - The Github version of dsd/mbelib can parse and play back D-STAR traffic.
- C4FM modulation
- GFSK modulation (including GMSK and other filtered 2/4 level FSK)
- QPSK modulation (sometimes marketed as 'LSM')
The following formats are currently under investigation or development:
- P25 Phase 2 - standard not finalized yet, vocoder is supported by mbelib
- OpenSky - four slot format vocoder may be supported by mbelib. Will not be supportable if it is determined that voice encryption is standard
- Other formats will only be considered if high quality samples of the signals are made available for download by the developers. Samples must be from a discriminator tap, .wav format, 48000Hz, 16 bits per sample, mono.
DSD and mbelib should compile on Linux and *BSD operating systems. Any linuxdistribution should work as long as it has support for your audio devices.DSD version 1.3 and later requires mbelib 1.2 or later.
The forum for discussion of this package can be found here.
Copyright License
DSD and mbelib are both released under a BSD style copyright license. This means that as far as copyrights are concerned it can be freely copied and used, including for commercial products as long as the original copyright notice is included. (However, see important patent issues section below.)
Patent Issues with mbelib
While DSD was intended to be patent-free, mbelib describes functions thatmay be covered by one or more U.S. patents owned by DVSI Inc. The source code itself shouldnot be infringing as it merely describes possible methods of implementation.Compiling or using mbelib may infringe on patents rights and/or require licensing.It is unknown if DVSI will sell licenses for software that uses mbelib. If you donot have a license and are in a jurisdiction protected by the DVSI patents you shouldnot compile or use this source code.

Frequently Asked Questions
Q: Do I need a radio with discriminator tap?
A: Yes, if you want to listen live or save mbe data files, and are using a scanner for input. No radio or discriminator tap is required to play saved mbe data files.
Q: Where can I get information on the discriminator tap for my radio?
A: Wiki information is available here for the Discriminator_output.
Dsd Audio Software
Q: Will this work on Windows?
A: As of December 7, 2011 binaries for Windows have been added.
Q: Will this work on a Mac?
Dsd Software For Mac Windows 10
A: No, because OS X does not use the traditional Unix-like /dev/audio interface. It shouldbe easy for someone familiar with Mac audio programming to port it to the Mac.
Q: Will you support decryption if I lawfully posess the encryption keys?
A: From the Readme file:
Q: Who are the author(s)?'
A: The author(s) are anonymous but PGP keys are provided inside the packagesso future releases/communications can be verified.
