    questions about Resample DSP

    If used from the command line...

    1. is Resample the latest-greatest DBpoweramp sample rate conversion engine, the one which features so well on the famous Infinite Waves SRC comparison site?

    2. Can I set both the Min and Max for Resample to 44100, so that if any file other than a 44.1 file is input, it will get converted to 44.1, and if 44.1 is input, Resample processing is skipped?

    3. Can I set Resample to output 24 bit instead of 16 bit if (and only if) it processed a file other than 44.1? In other words, if a 16/44.1 file is input, the output file be 16/44.1 ; but if a 16/48 file is input, the output file will be 24/44.1 ?

    thanks

    Re: questions about Resample DSP

    Thank you for the fast reply. For the scenario *2 above, if I use this command line syntax
    Code:
    "C:\Program Files (x86)\Illustrate\dBpoweramp\coreconverter.exe" -infile=%%A -outfile="M:\DJ\jDJproj\Trax\2B-Warped\%%~nA.aiff" -dspeffect1="Resample=-fmin={qt}44100{qt} -fmax={qt}44100{qt}" -convert_to="AIFF"
    it outputs the following
    Code:
    dBpoweramp Music Converter           (C) 2009 Illustrate Ltd
    
    Encoding: AIFF
    Audio Source: M:\MUSIC-BANK\misc\oct16\Uncharted - ManuMan x icekream.mp3
    Audio Destination: M:\DJ\jDJproj\Trax\2B-Warped\Uncharted - ManuMan x icekream.aiff
    DSP Effects: Resample
    
     0%-----------25%-----------50%-----------75%-----------100%
     Error DSP Resample Frequency not supported:

    ign: 4  CB Size: 0
    
    
    Writing ID Tags: Done
    Conversion Failed.
    The input file is 16/48. Curious why this is failing.

    You would have to enable debug log to see what it says, run dBpoweramp configuration.

    Re: questions about Resample DSP

    I have tried your command line and it works fine with R16, it must have been an issue resolved over the many years (your version is 7 years old).
