spectrogram

  1. Spectrogram time range

    REW Forum
    I was recently asked why I had the time range set to 500ms with a graph only displaying to 60ms. Unless I'm missing something, would it not be better to have time range just scale with graph axis limits?
  2. Interpret this spectrogram please

    REW Forum
    Hey everyone. Here is a spectrogram of my subs. I am just not entirely sure how to read it as far as what is good, what is bad, and what it is really telling me. Any expert tips?
  3. odd noises show in waterfall, spectrogram

    REW Forum
    Hi! First, let me say that I am a happy and experienced user of REW. I mostly use it with a MiniDSP 2x4 to room correct and provide EQ for Bose 901s, currently with a DIY subwoofer. I've come close to EQ-ing to my house curve (another concept I learnt here at HTS). What is odd is the past few...
  4. Spectrogram- no detail

    REW Forum
    If I generate a spectrogram, waterfall, or decay, I get a series of exactly parallel responses of the measured frequency response, but of diminishing amplitude. That is, no information is revealed. What might I be doing incorrectly? David
  5. Feature request for Decay / Waterfall / Spectrogram views

    REW Forum
    Hi, REW - its a great tool. Yes, the decay, waterfall and spectrogram views are exactly what we are used to. I use them to get an idea of where modes are and how fast the frequencies decay. I would find it extremely useful if I had the option to "level" the original frequency response. I.e...
  6. Possible bug in Decay, waterfall, spectrogram

    REW Forum
    I've just started using REW so it is possible I haven't set it up correctly, however, this does not look right. Setup: loopback using USB soundcard (Roland Quad-Capture). Impulse Response: Waterfall: Since this is a loopback, the IR is very clean and essentially no energy after 1 or 2 ms...
  7. Spectrogram ?

    REW Forum
    I've searched but I still can't find a good explanation of what the spectrogram is telling me. I know it shows energy, time and frequency and even negative time. Can someone give me a clue?
