While I realize you are not responsible for the FLAC encoder settings, are you able to provide any information on them? I am aghast to even the Basic flac encoder configuration settings. A google search for Joint Stereo vs Adaptive Joint Stereo provided little assistance. The presets 0 through 8 are only labeled by speed, however, what I am looking to optimize is quality. Anything I can do with the Format and Expert tabs to optimize quality?

How can one use the fre:ac and flac encoder settings to optimize sound quality regardless of speed or file size?

thanks much!!!

    Don't worry about quality of FLAC files! FLAC is a lossless format so the decoder output always exactly matches the original encoder input. FLAC encoder settings don't affect quality, only file size and encoding speed.

    Hello,

    didn't want to open a new thread for this, because it looks like this one is appropriate (but feel free to move it if necessary):

    In fre:ac snapshot 20120930 the FLAC encoder configuration dialog currently looks like this regarding presets:

    Custom settings
    0, Fastest encoding
    1
    2
    3
    4
    5
    6
    7
    8, Best compression

    And fre:ac snapshot 20120930 does default to "Custom settings".

    However, the FLAC documentation mentions the following:

    http://flac.sourceforge.net/documentation_tools_flac.html#flac_options_levels
    -0 .. -8 Fastest compression .. highest compression. The default is -5.

    Therefore, here is a suggestion/request:

    Please change the configuration dialog to look like this:

    Custom settings
    0, Fastest compression
    1
    2
    3
    4
    5, Default
    6
    7
    8, Highest compression

    and make fre:ac default to "5, Default", instead of "Custom settings".

    Ok, the next snapshot will have that changed.

    I also changed the default min/max partition order from 3/3 to 0/5 in custom settings to match the compression level 5 setting.
