Very ingenious idea and means to accomplish it!
Be Careful! To change the sample rate with any kind of quality requires very powerful signal processing computations and filtering.
There is a high probability that the resulting 32KHz file will be damaged so that Vogone will not work as well. We have shipped sample rate conversion software since 1986 and know the power required behind this function. It is unlikely that the two channels are processed absolutely identically. Thus, some loss in vocal reduction ability can be expected... i.e. it is doubtful if Vogone 2 will work as well with sample rate converted files.
You expressed (by phone) displeasure with Vogone 2's performance. I would expect it to now work as well with sample rate converted files. I will be waiting to hear if you have better success with any songs that you SR convert.
