Why Sample Champion requires a lot of RAM memory?

This is a consequence of the very high accuracy used for all internal operations. For example the FFT (limited for the user to 64K, but extended for some internal operations to 256K) is computed on double-precision complex data and using both frequency bands (positive and negative frequencies) to perform some specific signal processing operations and in prevision of any future DSP expansion (using special purpose plugins). To prevent any resizing or reallocating of the virtual memory during measurements, Sample Champion allocates, once started, all RAM memory required for working.
