Upsampling MQA files to original resolution with sox

[Alandbush]

The earlier stated sox command to upsample MQA (see below) is no longer supported, assuming it was correct initially.

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.
