sox -S input.mqa.flac output.flac -vsM 352800

For sox 14.4.2 the command is as follows:-

sox -S input.mqa.flac output.flac rate -v -M 352800

where 352800 is the original sampling frequency (tag ORFS) of the MQA file.

Thanks Alan,
I did it, but the output files is 16bit. Is there any way to produce a 24bit file?
if I put -b 24 the file becomes unlistenable.

I've tried the following command successfully on a 16bit MQA/CD track downloaded from 2L. It appears 'listenable'.

sox -S input.mqa.flac -b 24 output.flac rate -v -s -M 352800

nb - I have also introduced an extra override (-s 'steep filter'). If only because the command now looks very similar to the originally posted command.
