John Mulcahy replied to the thread REW Beta Release REW API beta releases.Well it will if you don't configure any filters corresponding to the crossover function you want! -
John Mulcahy replied to the thread Interface Calibration.Yes. It is done partly to make sure interface low and high end roll-offs are calibrated out, but mostly to make sure there is no...

John Mulcahy replied to the thread Interface Calibration.For interface cal replace the mic by a loopback connection, cal is for the measurement path.
-
John Mulcahy replied to the thread REW Beta Release REW API beta releases.See above, use Generate measurement from filters.
-
John Mulcahy replied to the thread REW Beta Release REW API beta releases.Did you use Generate measurement from filters, which will produce an impulse response from the current filter settings, or Generate...

John Mulcahy replied to the thread Scale limits in impedance measurement.Select log impedance axis in the graph controls.
-
John Mulcahy replied to the thread convolution room correction and room curve.To ensure you use the correct t=0 times for export and import you could use the options to place t=0 at sample 256 on export and use the...

John Mulcahy replied to the thread SPL: Inconsistencies between Windows 7 and Linux.The input volume shouldn't be active in WASAPI Exclusive mode, but you can adjust it via the Windows audio properties for the input.
-
John Mulcahy replied to the thread FSAF (Fast subband adaptive filtering) measurement.In the options you can choose to save the stimulus and response files for music, Michael would need those to investigate.
-
John Mulcahy replied to the thread convolution room correction and room curve.It export the IR of the minimum phase response generated from the system's magnitude response. When you import an IR you need to make...
-
John Mulcahy replied to the thread REW Beta Release REW API beta releases.I don't understand that question. FDW and MTW results are log spaced at 96 PPO and so have inherent smoothing of 1/48 octave.
-
John Mulcahy replied to the thread SPL: Inconsistencies between Windows 7 and Linux.Never raise the volume above a comfortable listening level. Clearly the displayed SPL figure is wrong on the Win7 installation. That...
