John Mulcahy replied to the thread Feature Requests(+Tips/Specs) for easier Room Treatment - Moving generate RT60; Displaying Tolerances in the RT60 Menu; Displaying Impulse Thresholds.Most of these are on the to-do list. I've made a change in the latest beta build so that generating the RT60 decay graph also runs the... -
John Mulcahy replied to the thread REW Beta Release REW API beta releases.Builds updated today (beta 86) with these changes: Added: 3D plot option for the waterfall and spectrogram data Changed: Generating the...

John Mulcahy replied to the thread Virtual balanced questions to John.Looks like the channels have a fractional sample timing offset.
-
John Mulcahy replied to the thread I can't get the FS sine Vrms on the signal generator to match the FS sine Vrms on the RTA window..The generator calibration shows the maximum output at full scale is 2.07 volts. Either it wasn't calibrated correctly or that is the...

John Mulcahy replied to the thread Virtual balanced questions to John.REW uses the input full scale voltage calibration data (see Calibrating the input level) to match the channels.

John Mulcahy replied to the thread How to use REW to plot DB and Frequency vs Time and Date on One graph.The SPL logger can capture SPL values for very long periods, logging to daily files. If you need to capture low frequencies use Z...

John Mulcahy replied to the thread Inconsistent SPL Readings and SPL Limit Errors During Soundcard Calibration in REW – Issue with Both Behringer UMC404HD and Focusrite 2i2 4th Gen.The SPL meter needs to be calibrated to show correct SPL figures. You can turn off the abort for excessive SPL on the Measure dialog...

John Mulcahy replied to the thread Individual house curve per mdat/project file?.You don't need a custom EQ to control the number of filters REW will use, it only uses those with the Auto option selected.

John Mulcahy replied to the thread Individual house curve per mdat/project file?.There isn't a workaround. The house curve data could be included in the mdat file, which would be better for portability of the...

John Mulcahy replied to the thread T60 and TR60 Graph results not showing.T20, T30 and Topt are all RT60 figures. RT60 decay data needs to be generated and the model fit calculated. T60M is the trace for the...

John Mulcahy replied to the thread REW does not see my UAD Apollo Twin Input.-435 dB means the incoming data is all zero. That happens if an app doesn't have mc permissions (it gets sent zeroes instead) but can...

John Mulcahy replied to the thread REW does not see my UAD Apollo Twin Input.Check REW's mic access permission in the Privacy settings.

John Mulcahy replied to the thread REW Beta Release REW API beta releases.Wouldn't that just be a mono conversion of the input channels? Or sum them. The timing signal doesn't overlap the sweep.

John Mulcahy replied to the thread REW Beta Release REW API beta releases.I don't understand why file playback wouldn't work for that, but I expect there's a reason.
