Rephase will be used to do the following steps:

1. tweak the EQ filter settings generated by REW and;
2. create the FIR filters for the BruteFIR software convolution engine that runs on Volumio

Choose Measurement/import from file to import REW measurement

Choose Ranges and adjust Amplitude to be from 0 dB to 70 dB (you should now have the same measurement graph as done in REW) Under Paragraphic Gain EQ choose import REW filter settings to import REW parametric EQ filter Configure following rePhase parameters: set taps to 65536, rate to 96000, filename to the name of of the filter and choose directory in which rephase will create filter Hit generate to generate and save FIR filter Save your work under File/Save settings
