Downsample WMA/FLAC Lossless to Apple Lossless from 96 to 48 KHz

[aamitabh]

Here is the CoreConverter command line I am using besides the -input, -output, and -convert_to options:

-dspeffect1="-resample=-frequency={qt}48000{qt}"

And all I get is a 40 byte file with the mp4 extension. What am I doing wrong here? I have tried with and without {qt}

Does the sequence of switches make any difference? I have convert_to option specified before the -dspeffect1 option. Is that ok?

If you remove the dspeffect line it works?

yes. All I have on the command line is -input ... -output.. -convert_to="Apple Lossless" -dspeffect...

-dspeffect1="Resample=-frequency={qt}48000{qt}"

Is correct not -resample

Awesome! work like a charm.
While the library conversion was going on I just realized that I have a mix of 88.2KHz and 96KHz music. What I would like to do is based on the input file sampling rate reduce the sampling rate from 88.2->44.1KHz and 96->48KHz. Can I do that?

You would have to programatically search for the different bitrates.

Ok thanks! that was precise enough. There goes my weekend.
