    DSF conversion Problem - loud distortion at track end

    Hi!

    I purchased DSD64 material online (David Munyon - Pretty Blue - www.highresaudio.com) and converted it with Music Converter to flac (and also only wav after finding the problem). The converted Files have a loud distrotion/Crack sound at the end of the tracks. tried with 96kHz and 88,3kHz.
    Converting the same files with foobar2000 works. The original dsf do not have the distortion. (as far as I can test)
    What am I doing wrong?

    Thank You!

        I could decode to 88KHz and 96KHz fine with my version, however looking through the code I did see a potential issue with DoP embedding, give this version a try:

          Analyzing with a wav editor there is a very short full dc offset in the resulting .wav. (see picture)

          Thank you for investigating further.

            Below the end of the wav before the bugfix (for comparison). So there is a huge improvement with decoder R3 (before was R2 - i checked before i updated)

              I have updated the beta codec to fix this, uninstall, download the new beta codec and reinstall.
