So people with OSX that would want to use REQW but firewire or USB interface that does work can try this, just disregard the reading of the higher frequency. Not sure if this is due to the lack of sound card calibration or if the MAx tool is less (or more) precise in the high end of the spectrum.Īll in all in the more critical lower range the IR device from max seemed to provide accurate results (compared to fuzzmeasure) when uploading the resulting IR in REQW. The measurement made with the Max IR tools give less smooth results then fuzzmeasure. I can still take measurements (allthough I cant export) in fuzzmeasure and they are very close. But I get results that are very similar with IR expect in the upper frequency (above 10k). Every M30 is individually hand-tuned and tested and is delivered with its own printed frequency response chart. I just figure that it wont take in sound card calibration that REQW or Fuzzmeasure offers. So I tested the Max IR tool and uploaded the IR to REQW. Allthough I do think EQ can help if your limited in your possiblity to treatement possibility and is a good addition to treatement. Treating your room, moving your speaker, etc.

An Electronic Calibration File (ECF) is generated for each microphone during final testing, and can be downloaded free of charge after product registration.Yeah REQW doesnt work on OSX with firewire cards.

With temperature compensated electronics the M30BX was built to deliver repeatable results no matter what the environment.Įxtremely fast impulse response and linear phase response make the M30BX ideal for use with high-quality FFT-based real-time audio system measurement software like SMAART, SIM, REW, Electroacoustics Toolbox, FuzzMeasure and others, as well as for use in PA system alignment and loudspeaker design.Įvery M30BX is individually hand-tuned and tested and is delivered with its own printed frequency response chart. It has a flat frequency response that extends from 9Hz to 30kHz, an exceptionally consistent omnidirectional polar response, 130dB SPL rating without distortion and no handling noise. The M30BX's audio performance is unparalleled. This M30BX requires 6V Lithium or 4 LR44 alkaline batteries. The M30BX is a precision engineered battery-powered 30kHz omnidirectional measurement microphone ideally suited for on-location acoustical measurements including loudspeaker design and quality control, sound system setup and troubleshooting, room acoustics, or any application where an accurate free-field measurement microphone is required and portability is important or a power source is not readily available.ĭesigned for remote use, the M30BX body opens for replaceable battery access, with a battery life of 300 hours. There’s also very little in the way of general guidance or context in the provided help materials. The small element yields an omni-directional pattern resulting in a wide pick up area at the front and sides of the microphone capsule. Some mic response and level calibration features are options, but in essence, FuzzMeasure is totally indiscriminate about a user’s poor working methods and measurement practice. The ultra wide frequency response of 9Hz to 30kHz is flat throughout the entire spectrum and results in accurate room calibration using Smaart, MLSSA, SIMM and TEF based systems. room mic for drums with good results, and it also works well with Fuzzmeasure. The M30BX is a cost effective measurement microphone intended for large and small room calibration. Though that mic isnt a calibrated one, I could still easily see that the.

Perhaps there was some object in the room, close to the left speaker, that has a natural resonance at 41.9 Hz? Maybe you could post pictures of the room exactly as it was when you took those measurements. It's also much larger on the left speaker and hardly there at all on the right, so I'd guess it is something physical in the room that is resonating, not a room mode. However, the second big peak is 41.9 Hz in REW, but your second axial mode (0.1.0, width) is predicted to be at 48.4 Hz., so that doesn't match at all. which is length) at 36.2 Hz, Looks like a very close match to the actual results! I'm seeing the first huge peak at 35.8 Hz in REW, which is basically a direct match. In your first post, you said: "My room is 3,56m wide, 4,76m long, 2,76m high.".

(I'll also use Sonarworks once I'm happy with the treatment results).Īny idea on how to treat the big decay from 30Hz to 50Hz?Those are resonances, not decays. Maybe everything is normal and I just need to go ahead and hang all my acoustic panels, play with speaker placement and call it a day. I did all my measures with my duet (2008), maybe it's faulty (I calibrated it in REW, but not in Fuzzmeasure). But not all of them appear in REW (100hz for example). I get weird ringings around 35Hz, 100 and at 15k that seem to go on forever. Second problem is the waterfall in Fuzzmeasure. The fuzzmeasure one seems more coherent in my experience. The REW one seems all twisted, with a big bump in the midrange, and a big large dip in the highs. The first problem is the in the Frequency Response differences between the two softwares. I get a nasty metallic ringing when I clap my hands at the listening spot, so that confirms it. This means the clouds and wall/ceilings panels are not doing their job yet, hence the big mess in the highs in my measurements (as expected). But they are not hanging on the walls yet, just resting on the floor. I put my acoustic panel at the first reflections spots and big corners (6 GIK panels, 3 Soffit panels, 6 diy panels). I put the mic at 38% of the length from the front wall (figured I'd start here and move the speakers first) My speakers are almost touching the front wall (see beautiful sketch I did) Maybe you guys can help me make sense of it? I just moved to a new room and I get different measurements when I use Fuzzmeasure and REW.

And this was with the relatively modestly priced Ayre CD player and integrated amplifier. While both pairs of Vivids were imaging champs, the B-1s' soundstaging was some of the best I have heard, with superlatively solid and stable images. I was as impressed as John had been by the V-1.5, but after some extended listening, it was clear that the more expensive B-1 was indeed the better speaker: It sounded more neutral, its treble was better matched to the room, and its bass extension was more satisfying. Conversely, the V-1.5 doesn't excite the resonances in JM's room as much as the B-1 does. In the bass, the smaller V-1.5 has both less low-frequency extension and less mid- and upper-bass energy than the B-1, but both speakers benefit from some reinforcement from the lowest-frequency mode in John's room, at around 38Hz. Both speakers have a small peak at 600Hz, though this may be a room effect that has not been minimized by the spatial averaging. JM thought the B-1 revealed a slight midrange nasality in the V-15's sound I suspect that this is connected with the slight step in the V-15's room response just above 1kHz, though the B-1's response is slightly less smooth overall. However, the V-1.5 can be seen to put out a touch less mid-treble energy than the B-1. I didn't calibrate the absolute sound pressure levels in this graph, and so have arbitrarily matched the levels at 1.5kHz.įig.1 Spatially averaged, 1/6-octave response in JM's listening room of Vivid B-1 (red) and Vivid V-1.5 (blue).īoth speakers roll down gently in the treble, which is the effect of both the limited dispersion of the tweeter above 10kHz and the increased absorption of the room furnishings in this region. The results are shown in fig.1, the red trace showing the spatially averaged response of the B-1, the blue trace that of the V-1.5. (I used an Earthworks QTC-40 omni microphone and a Metric Halo ULN-2 FireWire audio interface, in conjunction with SMUGSoftware's FuzzMeasure 2.0 running on my Apple laptop.) In a room of typical size, this measurement integrates the speaker's power response with its direct-arrival sound to give a graph that tends to correlate quite well with its perceived balance.īoth pairs of speakers were placed in the same positions in John's room (see photo). I perform this measurement by averaging twenty 1/6-octave–smoothed responses taken, for each speaker individually, in a rectangular grid measuring 36" by 18" and centered on the positions of the listener's ears in the listening chair. As John Marks mentions, as I was visiting him to both check out his new listening room and listen to the two pairs of Vivid loudspeakers, I took the opportunity to measure each speaker's spatially averaged response in his room.

discard the measurement if there were any pops or clicks during the sweep or if the impulse response does not resemble previous measurements. The impulse peak is not where it should be, the measurement may have been corrupted. matching the levels each time i get this message. so anyway i match the levels at the calibration stage again and click next.then finish so it takes a measurement. An RTA is really not very good for tuning the room. I think theres also a Smaart extension for one of the iPad/iPhone apps that give you the transfer function display. to find/tweak acoustic issues of the room but for final tuning Smaart is very comfortable. so i switched from the 4th preamp mic input back to the second preamp mic input and i pick up signal on REW. That said, REW & Fuzzmeasure are great tools for waterfall displays etc. i don't even get a signal when the ECM8000 has 48v and I'm clearly picking up audio on the interface but not on REW. using SMUGSoftwares FuzzMeasure 3.0 program and a 96kHz sample rate. I connect the measurement mic to my 4th preamp input and turn on 48v. So I drew a line from the tweeter to the 36 height of my ears, 106 away. So i load back up the calibration file i already had from when i was working with GIK. I don't own a Mac, but some people prefer the commercial (and affordable) FuzzMeasure program meant for Macs.

got it.i click on calibrate and click next so the 1k tone plays constantly. REW also works with Mac and Linux computers. At that point, you should be able to measure a speaker, then switch the second speaker into the same measurement position, and measure it.

the video shows a small interface and says connect a cable going into an output then into an input. You need to measure the speaker output, using something like REW or FuzzMeasure, so you need a computer, the right software and a measurement mic. Next it goes to setting up the loop back. got it.universal audio apollo selected on output and input device. now in the video it starts by having yo click on preferences and select your interface. FuzzMeasure is one of the many helpful tools I use to do my job effectively.Ok so i started all the way from the beginning following the video. That means even though REW is cool, Dirac simply has superior results. Dirac is automated and has the most advanced algorithms out there (It uses mixed-phase filtering - in effect, a combination of IIR and FIR filters.) and also correct impulse and timing. Before FuzzMeasure, I did all this by ear. REW lets you design filters to correct frequency response. If indeed my ECM8000 is actually flat above 10khz, and the calibration file is rolling it off, due to the average ECM8000. When the ARC system uses the same mic to measure, you can see the rise above 10khz.

A lot of clients just want you to tune the room fast and FuzzMeasure has definitely expedited the process.Ī lot of mastering engineers don’t do their own room scans however I feel that you have to know how to do your own work in case something gets accidentally moved or bumped. Anyway, Im aware of the rise above 10khz on the ECM8000, but I dont see much of a difference in REW with and without a calibration file. I'm not the guy designing rooms on a piece of paper, but I can tell you if a room sounds good or not. I’m not a trained acoustician, I’m an audio engineer. The decay time you see in your measurements includes reflections in the room, Amir measures decay produced by the speaker itself, resonances in cabinet and drivers. When using a USB microphone with REW, time-synchronized measurements must be performed using REW's 'acoustic timing reference' feature. Using a USB Microphone: Acoustic Timing Reference. To be able to show both the Waterfall and Reverb Time (RT60) graphs at the same time, without having to close one and then open the other, will save a lot of time as far as them grasping the scope of problems in the space. Because you are actually measuring your ROOM with REW. REW is a popular choice for measurement software, and is recommended as the first choice for use with MSO on all platforms. (2) Huang Ren Zhongs striped parasol stands out against the muddy cliff of excavated. FuzzMeasure is simple and affordable - the kind of tool that will empower the next generation of designers, consultants, and researchers. Example Sentences: (1) Among the 10 tissues examined, endogenous renin transcripts were identified in and restricted to kidney, submandibular gland, testes and ovary consistent with the expression pattern of the Ren-1c gene. I’ve also tried exporting each SPL measurement in REW and selecting the ‘normalise’ option during the export but when I re-import the measurements they’re not normalised to the same. Architectural acoustics is more complicated than it should be. In Fuzzmeasure, there a little tick box for each measurement that allows the frequency domain to be normalised, but I cannot find a similar option in REW.
