Mitch Barnett of Accurate Sound tells us about his journey to become a leading expert in Digital Sound Processing (DSP). Accurate Sound is a remote service using Audiolense, Acourate and Room Eq Wizard (REW).

Dear experts I am a real rookie in this field, so pardon my ignorance. I managed to make a setup with my calibrated UMIC-1 and made a measurement. I do not know what to do next in order to generate a EQ filter for use in software TRD NOVA. What does 'target level' do? Must I change it? I get...

As the title states this is my first foray into taking actual room measurements. I'm a firm believer in room acoustics, speaker and listener positioning, distances from walls and speaker boundary interfaces. I'm using a UMIK-1 ver2 on a boom stand. USB into my HP Envy Tower --> USB RME ADI-2...

I've had these two speakers for a very long time, but I've never really gone into a detailed comparison between these two side-by-side before. This exercise is going to be divided into sections, so just skip ahead to the areas of interest to you. Also, I'm going to be focusing on the Sceptres...

I am trying to fine tune the phase for a Rhythmic L12 and a near field setup. The subwoofer is behind the listening position. Subwoofer is crossed over at 80hz via the amplifier crossover. Posted is a snapshot of the RTA using Pink PN with a sequence length of 64k, full range. Also included is...

Hi all, due to the fantastic measurement results of the Genelec 8030C I ordered them in order to upgrade my current system. Today I made some measurements in order to compare the new to my old system. The results show that the old system is at least in the current room set up better - which is...

Puzzled by the Harman Curve presented here : http://www.audioheritage.org/vbulletin/showthread.php?39134-Harman-Target-Curve and attached in a smoothed version here, I have aligned the Time Windowed Vector Average of a bunch of measurements one can make in REW to this 16 dB wide sinuous Harman...

I have been inspired by the many measurement-based audio equipment evaluations posted on this forum. I want to try my hand at making my own measurements. Since I don’t own an APx555 or similar test setup, I needed to use more of a DIY approach. This is my first posting here, and I seek...

Up until recently I was using the Digilent Analog Discovery 2 to perform audio measurements on my DIY audio projects - with 14-bits of resolution, it's a surprisingly powerful and cost effective little device. And while still an exceptional and blisteringly fast scope - I honestly can't see...

I'm an audio DIYer, and I want to start making high quality measurements of some of my designs - power amplifiers, headphone amplifiers and preamps. I've got a decent scope, some high power dummy loads and some highly precise attenuators I've built - so all I need now is a decent soundcard or...

Given that the MiniDSP SHD and the RME ADI-2 Pro fs both use the same AKM chips, have similar specs, and in Amir's DAC testing showed very similar performance, is it safe to assume that the ADC performance of the MiniDSP SHD is likely to have a SINAD within a few dB of the RME ADI-2 Pro fs? I...

@mitchco Mitch Barnett recently launched his Accurate Sound Calibration Service. Mitch has been a great teacher to many. Mitch is a DSP, low frequency optimization and active loudspeaker enthusiast and evangelist. Mitch has written extensively on this topic which includes a complete guide in...

I am new to REW and measurements in general, read some tutorials and did my first ones using the gear that I already have: a Focusrite Scarlett 6i6 2nd gen USB audio interface, and an M-Audio Nova cardioid, side address, large diaphragm condenser mic. The Nova is not made for measurements, so...

I was searching for a cheaper alternative to umik-1 (€140) and I've find this usb mic (€59). Given that the objective is some basic room eq measurement, could it be anyhow comparable to the umik?
