Hi Tod, In my HT , I only use a HTPC ( its an MSI gaming series PC infact ) as a source. I stream movies over Kodi or Stremio, I watch youtube, I stream music and the PC also has a DVD slot , that I seldom use. So I installed Equalizer APO 1.2.1 on it. That is a free Parametric multiband equalizer for Windows using Audio Processing Object (APO) technology, which allows you to change the sound parameters of all applications at once at the operating system level. Using REW measurements of the raw system and choosing a certain room correction curve, I can create some sort of automated correction file that can be uploaded in APO 1.2.1. In other words, I don't have to play with the parametric equalizers myself. I only have to point out my desired room correction curve . Of course , before starting , I made sure I had my two subwoofers at the best place in the room to prevent dips and I have a pretty good acoustic threated room to begin with.
If you can edit your description, I suggest deleting the apology for your "bad" English; it's fine! Thanks for the video. What parameters do you have selected in the RTA controls, and why?
Hi, I have Mode : RTA 1/48 octave , Smoothing : No smoothing ,FFT Length 64k , Averages : forever , Window : Rectangular , max Overlap 50% and as I explained in the video , I set Appearance to "adjust RTA levels" In my search for good useable settings i found my solution at this forum : www.audiosciencereview.com/forum/index.php?threads/rew-moving-microphone-method-help.12641/ post 13 april 18 2020 After reading some info regarding windowing, I found the following : The FFT resolution is also affected by the setting. Rectangular windows give the best frequency resolution but are only suitable when the signal being analysed is periodic within the FFT length or if a periodic noise signal is being measured. The Rectangular window should always be used with the REW periodic noise signals. Most other signals, e.g. sine waves from the REW generator or test tones on a CD or random noise, typically would not be periodic in the FFT length. Using a rectangular window when analysing such a tone would generate spectral leakage, making it difficult to resolve the frequency details www.roomeqwizard.com/help/help_en-GB/html/spectrum.html As I showed in the video , I have used the REW generator with periodic pink noise and thus I set the RTA at rectangular
i dont understand how these measurement readings work. my microphone volume is all the way off and im still getting frequency graph readings. if i turn up my mic it starts to feedback. ive watched lots of videos but seems confusing. ive copied every settings from multiple videos and still the same happens
if the mic is feeding back it is playing through the speakers which is incorrect for measuring. You shouldn't hear it through the speakers if you talk into it. The mic will still be able to measure signals even when it's not in the speakers.
If your RTA MIC is on but you are not sending out any sweeps or pink noise then what you are reading is the actually room levels. This is common and typically consider in the decision on how to EQ a room. For example, you might notice higher reading with a fan is on vs not. I'd recommend looking it up and learning how to understand it to get more accurate tunes for your room. Cheers
Thanks for the video I will try the mmm. Do you use any sort of room correction DSP like the miniDSP-HD? Tod in Vegas 😊

Great rew video can you share more tips and videos

Is it possible to do a house curve on rew with a geq Yamaha equalizer
did you find that out please? best regards in advance!
@@vortexor1 yes it can be done
thanks for your answer! is there any blog where i can find out how it's been done? @@msoles30
Great video!!!
