  • Bug Fix: There was an issue to transform FLAC into the DSF (DSD) format.

Version 1.2.4 (06.01.2016):

  • The DSF file output was not completely compliant with the standard, causing issues with dedicated DSF-Tools.

Version 1.2.3 (27.12.2015):

  • The conversion speed of PCM to DSD256 and DSD512 has been heavily enhanced.
  • The new „ISP Reduction“ switch offers the deactivation of the Inter Sample Peak Reduction Algorithm to allow the direct comparison with Sample Rate Converters that do not provide that feature.

Version 1.2.2 (23.12.2015):

  • The function to read and write DSD512 – Octuple Rate (22.5792MHz) Direct Stream Digital has been added

Version 1.2.1 (16.12.2015):

  • The DSF output format has been added. Now it is possible to save Direct Stream Digital as DFF or DSF format.

Version 1.2.0 (11.12.2015):

  • XiSRC got now PCM to DSD (Direct Stream Digital) conversion by using a high quality Sigma Delta Modulator.
  • Furthermore the following DSD sample rates are written into the Digital Interchange File Format (DFF):
    • DSD64  2.8224 MHz
    • DSD128  5.6448 MHz (Double Rate DSD)
    • DSD256 11.2896 MHz (Quad Rate DSD)

Version 1.1.1 (23.11.2015):

  • Bug-Fix: Windows 10 drag and drop issue fixed. 

Version 1.1.0 (20.11.2015):

  • Optimized Audio Processing Engine
  • A new Scrollbar, within the settings section, allows for a smaller application window.
  • The internal audio player got a pause button.
  • Now it is possible to work on single files and a whole folder structure. If an “Output Folder” is selected then the folder structure gets replicated otherwise the converted files are saved within the original folders by using the given naming convention.

Version 1.0.10 (16.09.2015):

  • It is now possible to reduce the CPU-Load by activating single-threading, which limits the CPU usage to one core.

Version 1.0.9 (14.09.2015):

  • We implemented an internal test signal generator to allow the verification of the XiSRC Sample Rate Converter at any time.
    A right mouse click within the list opens a context menu. Selecting „Create Test-Signal“ opens a GUI where it is possible to choose between a sinus and sinus sweep. After setting all parameters (Sample Rate, Amplitude, Test-Signal Frequency and Target File Name) the test signal appears in the list, similar to any other audio file loaded. Finally, it is possible to convert the test signal into any sample rate or bit depth for further investigations with software like the MusicScope to verify the XiSRC performance.
