    converting quadraphonic Q8 24/96 wav to WMA lossless

    Hi All,
    I have a few quadraphonic 24/96 files. dbpoweramp does not have a way to convert them to 4 channel WMA lossless files. The only option I get is 24 bit 2 channel or 24 bit 5.1 channel.

    Even if I convert 4 channel to 5.1 channel, how are the center and LEF channels created?

    Cheers. -aamitabh

    You can use DSP effect to channel map on conversion. The limitation appears to be with WMA, all the available modes are presented.

    Ah thanks Spoon! I will try that.

    But what is the algorithm for the default option of converting quadraphonic files to 5.1, by using the standard option?

    Also, Would you add another dropdown option for 4Chanel, so that I do not have to use channel map DSP.

    Thanks. -aamitabh

    It is Microsoft which set those encoding options, we jsut read all possible modes with WMA.

    The mode 4 channel to 6 channel is not optimized (unlike 2 >> 6 or 6 >> 2), so the last 2 channels will be a sum of the other channels.
