John Mulcahy's latest activity
-
John Mulcahy replied to the thread Setting to disable automatic determination of Ref in IR plots.There is an button on the IR windows dialog to apply the current window settings to all measurements. The window ref is less important... -
John Mulcahy replied to the thread MacOS measurement attenuation above ~10kHz.Check the sample rates in Audio Midi Setup and make sure the UMIK is selected as the input device. If there's a significant latency in...
-
John Mulcahy replied to the thread REW Beta Release REW API beta releases.Can you get a screenshot?
-
John Mulcahy replied to the thread SPL V/V graph help.There is an option to use the reference input as a cal source. The V/V scaling is independent of any timing or cal reference, since...
-
John Mulcahy replied to the thread SPL V/V graph help.Also worth comparing the no-load output voltage at the chosen sweep level with the output voltage when loaded by the device, which...
-
John Mulcahy replied to the thread SPL V/V graph help.Have you compared the voltage at the input to the device you are measuring with the voltage at the soundcard output? REW's gain is based...
-
John Mulcahy replied to the thread John, how much data is saved with each REW measurement?.Nonetheless the measurements only differ meaningfully above around 7 kHz, once the windowing is set the same and smoothing is minimised...

John Mulcahy replied to the thread John, how much data is saved with each REW measurement?.Frequency Dependent Window, that's why the name shows [FDW] in the graph legend.
-
John Mulcahy replied to the thread John, how much data is saved with each REW measurement?.If you were really playing both speakers, as the L+R output setting suggests, then even extremely small differences in mic position can...
-
John Mulcahy replied to the thread REW Beta Release REW API beta releases.Probably easier to just copy the mdat, or save that measurement to an mdat if it is part of a multi-measurement set, then you get an...
-
John Mulcahy replied to the thread John, how much data is saved with each REW measurement?.If you look on the Info panel it will show any cal files used for the measurement. You can see the frequency response of the cal files...
-
John Mulcahy replied to the thread SPL V/V graph help.Too little information to comment. What are the generator and RTA settings and the full scale input and output voltages? Which graph are...
-
John Mulcahy replied to the thread REW Beta Release REW API beta releases.Same as before, Filter tasks - Generate measurement from filters with no filters active.
-
John Mulcahy replied to the thread SPL V/V graph help.The dBFS differences depend on the relative voltage scalings of the output and input.
-
John Mulcahy replied to the thread REW Beta Release REW API beta releases.Builds updated today (beta 65) with these changes: Fixed: STI clipboard copy copied TI values instead of m values Fixed: Embedding FSAF...
