    TuneFusion conversion from FLAC to M4A does not support Gapless ITUNSMPB tag

    Hi,

    I switched from Batch Converter to TuneFusion at your recommendation for my workflow last June:
    https://forum.dbpoweramp.com/showthr...103*post192103

    However, I have now noticed that TuneFusion's "m4a FDK (AAC)" encoder does not support the ability to configure Gapless Signaling as does Batch Converter/Music Converter. The latter has an Advanced Settings button that allows you to pick the encoder Profile and the Gapless Signaling option (iTuneSMPB). When selected, the post-conversion M4A file contains an ITUNSMPB tag that supports gapless playback.

    Is there a way to enable the generation of the ITUNSMPB tag when using TuneFusion to convert my FLAC files to M4A?

    Thanks,
    Dennis

    On TuneFUSIONs configuration page, the encoder settings are exactly the same as for Music Converter, it is the same codec, there is an advanced button which allows access to the Gapless setting.

    Thanks for the prompt reply, but I see a different encoder settings page for TuneFusion 1.2 than for Music Converter. Please see attached images for both. There is no Advanced button on the TuneFusion page.

    Is there a different TuneFusion configuration page I should be looking at?

    Thanks,
    Dennis

    Re: TuneFusion conversion from FLAC to M4A does not support Gapless ITUNSMPB tag

    Thanks Spoon. But I am unable to install it. I started by installing it over v1.2 as recommended, but each time I do, I get the dialog box in the attached message. I have rebooted twice now, and then I try the 1.3 install again. But I get the same dialog box each time.

    Running Windows 10 on latest updates.

    Any suggestions?

    Thanks,
    Dennis

    Thanks Spoon. But I'm unable to install v1.3 beta over 1.2 (as recommended). When I try, I get the dialog box shown in the attached image. I have rebooted 3 times, but still get the same message.

    So I reinstalled 1.2 and tried to then install 1.3 beta again; but I still just keep getting that same dialog box even after rebooting.

    I am running Windows 10 with the latest updates.

    Any suggestions?

    Thanks,
    Dennis

    Re: TuneFusion conversion from FLAC to M4A does not support Gapless ITUNSMPB tag

    Related question: TuneFusion 1.2 is configured to do a 1:1 copy of my existing M4A files from the source to the destination directory. The M4A files do appear to be copied (rather than re-encoded) because the process is instantaneous. But the ITUNSMDB tag that is present in the source directory copy is removed by TuneFusion and is no longer present in the destination dir.

    Two questions:
    1) Is this fixed in 1.3 beta?
    2) What is it that TuneFusion changes during the 1:1 copy of M4A or MP3 files?

    Thanks,
    Dennis

    It was fixed yes, in 1:1 copies the tags are re-written. I will have to check if itunsmpb is preserved.

    We will start work on TuneFUSION again soon and release a new beta update.

    Music Converter adds the ITUNSMPB tag when encoding from FLAC to M4A, and also preserves ITUNSMPB when doing a 1:1 copy of M4A files. It's essential for my collection to have gapless playback supported. So I do hope both the encoding and 1:1 copy have been fixed in TuneFusion 1.3.

    Great. But just to set my expectations, by "soon", are you thinking weeks or months?

    Thanks,
    Dennis

    Could be weeks as there have been other mods made to TF which need posting to beta.

    Hi Spoon,

    I saw that you had release a new 1.3 BETA for TuneFusion on 5/19 and that it was supposed to have a fix for preserving the ITUNSMPB tag: "iTunes gapless preserved on m4a (aac) when doing a 1:1 copy".

    However, I installed the new beta today, and it still does not copy the ITUNSMPB tag when doing a 1:1 copy of M4A files. Furthermore, it also does not add an ITUNSMPB tag when converting from FLAC to M4A.

    As I had mentioned earlier, Music Converter does both these things.

    So I am not sure if I have the right beta. I downloaded it from the link at the start of the "TuneFUSION R1.3" thread": http://www.dbpoweramp.com/beta/TuneFUSION.exe
    Is this the right link to use?

    If so, is there anything I can do to help identify the problem?

    Thanks,
    Dennis

    I just took the existing TuneFUSION install and manually cleared out all the files and subfolders in C:\Program Files\TuneFUSION

    then installed the beta. Setup a sync where 1 m4a file would be 1:1 copied and one lossless file encoded to m4a, both resulting files had the iTUNSMB tag.
