  1. Pls help me understand the relationship between input level, dBFS and SPL levels

    REW Forum
    For some reason, I am having difficulty understanding the relationship between the Control Input Volume and the dB FS Output level shown on the REW SPL Meter. This misunderstanding arose after I entered the Sensitivity parameter for my UMM-6 USB mic into the calibration file, and then tried to...
  2. What does dBfs tell us

    REW Forum
    Hi all - puzzling question? In the impulse window, what does the dbfs readout actually tell us about the room? and what is the difference between it (dbfs) and the ETC dbfs graph, so why would i choose one over the other? do they tell us different acoustic events, all help much appreciated.

  4. REW DBFS

    REW Forum
    Just wondering how accurate the DBFS output level is in REW. For example I have calibrated my system using AVIA on my HTPC with PowerDVD, to be at reference level 85db. When I use REW I set the output level at -20 DBFS, but the signal is 6db hotter then the calibration, and that is with only...
  5. AVIA & DVE actual dBFS levels

    AV Home Theater
    I thought this may be of interest. I now have both DVE(HD DVD/DVD combo) and AVIA. So I was able to load them both into Sound Forge and check the dBFS levels. I did some more reading on Sound Forge and found a more precise way to check the dBFS levels using the Normalization feature where I can...
