    The wave file is 16 bit, 2 channel, 44KHZ?

    I am not sure how you can debug this issue, perhaps disable security software?

    I created a fresh Windows 10 machine, added iTunes latest, installed dbp + qaac and it encoded correctly.

    Sorry to bring back a dying thread, but...

    I'm getting the same error as cinnabardk when trying to convert from FLAC to QAAC. I tried each of the 4 presets to no success. Below is a snippet of the error log from trying to convert the whole album.

    Code:
    Error converting to m4a QAAC (iTunes), 'C:\Users\ruscra\Music\Nujabes\Spiritual State\01 Nujabes feat. Uyama Hiroto - Spiritual State.flac' to 'C:\Users\ruscra\Desktop\01 Nujabes feat. Uyama Hiroto - Spiritual State.m4a'
    Here are the audio properties of this file

    Code:
    Artist Nujabes feat. Uyama Hiroto
    Title Spiritual State
    Album Spiritual State
    Track 1/14
    Disc 1/1

    Sample Size 16 bit

    Channel Mapping 
    File 01 Nujabes feat. Uyama Hiroto - Spiritual State
    Type FLAC Audio    [.flac]

    I am running

    • Windows 10 Pro 64-bit, build 18363
    • dBpoweramp R16.6 64-bit
    • iTunes 12.10.4.2.


    The only security software I have running is 10's built-in antivirus. I disabled real-time protection and tried to convert the above file again -- no success. Test conversion worked without a hitch. I was also able to convert to MP3 VBR -v2 with no problems either.

    Re: m4a QAAC Encoder (iTunes) not working.

    Not sure what to suggest, this plug-in was developed by a 3rd party so we are not involved in that. You would have to test other QAAC scripts (perhaps try a command line version and a wave file) to see if that works.
