analysis

Hi please can someone tell me measurements required for my system. Main speakers Energy Veritas 2.3i and centre, velodyne dd12 and dd15 dual mono, receiver Yamaha Z9. Thanks in advance

I am little bit confused where to start the room acoustic analysis for Home theatre setup. First priority is for low end and the second priority is for mid and high end analysis. My question is Whether to choose SPL meter with line out like galaxy audio cm 140 or linear condenser mic like...

Is it possible to run the MATT test/analysis via REW? acousticsciences.com/matt

I've exported a set of measurements as text so that I can analyze them using Matlab. I'm running into trouble extracting an impulse response from the magnitude and phase data that are exported. To be sure I had my ducks in a row I first simulated an impulse in Matlab and added a bit of noise. I...

Hi please someone help If we measure Left>Right>Combined wouldn't it be best to do analysis e.g. EQ on the average of left & right, this would take out the discrepancies e.g. timing? Thanks

recently DIY speaker build, my first. so now want to take some measurements. i have a Roland Quad-Capture interface into computer and dayton EMM-6 microphone. put a loop back patch cable on input 1L and output 1L. Microphone into input 1R and speaker cable to output 1R. never could get the...

Hi, I would like to point the attention of REW developers to this fresh AES paper published a few days ago: Synchronized Swept-Sine: Theory, Application, and Implementation The paper claims that using their own swept sine function and analysis method leads to better HHFR (Higher Harmonic...

Hi All, I'm still struggling trying to really understand the REW results I get after taking a measurement. Would any of you be willing to look at my results and give me guidance on what I need to work on improving in my room? Your opinions would be appreciated. Thank you, Robbie

Can anyone elaborate on this: "After V5.0 the waterfall behaviour has been enhanced to improve control over its appearance and extend its use to include the analysis of drive unit and cabinet resonances."- From REW V5.1 Help

Hi Folks, I measured Genelec 1031 Speakers with different sound optimizers/equalisers in a broadcast truck for a student projekt. Guess that might be interesting for many of you too ;-) Now I made Waterfall graphs and I think/hope I analyzed it right. There are quite big differences in the...

Good day to ALL :wave: I am new in the forum ( http://www.hometheatershack.com/forums/welcome-member-introduction/111530-hello-central-europe.html ), not new in the high-end audio but new in room acoustics... My grand children are growing and starting quickly to be very interested by any...

Hi, I've been playing with REW and noticed there's a display titled 'Zeros and Poles' so I'm assuming that's referring to the zeros and poles of some analytic function. Is there a description of this function and what the plot tells you I could understand? I was an algebraic geometer at one...

Hi, First post here on the forum or any forum for that matter! Anyways, I'd like someone to chime in regarding the following questions. I will be using the room to mix mostly but of course enjoy listening to some tunes as well. 1. When measuring the rooms FR, does the software take into...

Friends, I'm trying to understand measurements I've taken of an all purpose live! room. Room size; L 5 meters x w 3.4 m x h 3.m. The room is heavily carpeted floor and 1m up the walls. I can see modes problems around 60-100Hz & 400-800Hz with bad attenuation from 5kHz onwards. My response is to...

I am an acoustic musician who joined primarily to gain access to REW software for specific testing purposes a little off the beaten path for home theatre discussions. I suspect there are many very savvy people here at this software and your input in my testing process is appreciated. My...

Hi! They sell a little microphone to work with apple iPhones. I asked the vendor and the mic would also work with my type of android smartphone (Samsung S4). However, he could not recommend any apps to to the analysis work. I searches the forums but could not find this topic allthough I...

Hey guys, This is kind of related to my other thread over in the acoustics section: http://www.hometheatershack.com/forums/home-audio-acoustics/73922-living-room-ht-set-up-need-acoustics-advice.html but I thought I would post here for some more specific advice with regards to analysis of the REW...

This is my first time using the simulator, which I am trying to use to determine prewire location for new construction. My space is not a perfect rectangle by any means so I understand that this is not going to be the most accurate. I was hoping I could get some feedback on the 3 locations that...

Hi all, what is the impact of vibrations from a rack on a DAC, preamp or an amplifier? And if there is an impact, how exactly is it happening? I mean vibration induced by air waves from the speakers and/or floor on the shelves, structure of the rack and not on the equipment itself. I welcome...

For the above if I was to have time to do ALL that I need for analysis what would I need e.g. for timing/distance, phase, polarity, crossovers etc prior to EQ? Also after EQ which measurements would be affected? Also order of measurements? This is to take full advantage of measuring time...
