    [codec] m4a FDK AAC Encoder

    We will be phasing out the Nero encoder and replacing with this newer FDK version.

    Includes also a m4b encoder.

    <now released>

    Encoder.exe"]dBpoweramp-Codec-m4a FDK (AAC) Encoder[/URL]

    This install contains both 64 bit install (for dBpoweramp R15 beta 64 bit) and 32 bit install. By default the install will match your dBpoweramp (32 bit or 64 bit).

    Installed but unable to get it to work. Tried to convert a FLAC file and it does nothing.

    I still have the Nero encoder installed. Do I need to remove it?

    It is independent of the Nero encoder.

    When you say does nothing, you mean it converts and finishes, but there are no output files? no errors?

    No, it doesn't convert anything. The time elapsed keeps going up but the files will not convert at all. I eventually have to use task manager to get it stop, as clicking cancel doesn't work.

    I will uninstall and reinstall to see if I possibly did the install wrong.

    EDIT: Found the problem! My antivirus was blocking it as a "questionable" program. I took off the blocker and it works fine now.

    Hi admin.

    This fdk-acc encoder doesn't have any custom option such as he-aac mode, cut-off frequency or vbr mode. When i check the spectrum of output file created by this encoder i see although encoding at 192kbps but the frequency is cut off at 16 khz.

    I hope you will add an option for cut-off frequency and vbr mode. Thanks.

    HE and HE v2 engage automatically under set bitrates (96 and 48 respectively)

    The VBR mode for this codec is only for very low bitrates (less than 64 kbps from memory, adding a VBR option would confuse in our opinion).

    Re: m4a FDK AAC Encoder

    Hello. I have maked a new fdkaac.exe using this:
    fdkaac_autobuild

    I have replaced the new exe in folder "C:\Program Files\Illustrate\dBpoweramp\encoder\m4a FDK (AAC)". In the encoded m4a files, i see in tag "fdkaac 0.3.0, libfdk-aac 3.3.3". Anyone knows what are the changes in this new version?
    P.s.: sorry for my bad english... :p

    >New option --moov-before-mdat was added at 0.3.0

    This addition would not be used by dBpoweramp as we actually internally already move the moov before mdat...

    Does this m4b encoder replace the dBpoweramp m4b Audio book Encoder (32-bit) I downloaded and installed in 2012?
