    How much gain do I need?

    Hi there. I'm trying to use Rew+RePhase+Eq Apo with my current setup: Amazon Music via laptop=>Topping D50s=>Rotel Rb 1552 (sensitivity 1.5 volts)=>Wharfedale Linton. I have built up several filters and noted that with some of them the music sounds a bit recessed. So I thought to insert a preamp...

    Royal EQ Rumble! Objective measurements of Dirac vs Audyssey vs REW+EAPO vs Nothing

    I have always been interested in comparing the results of equalizing my speakers using REW, Audyssey, and Dirac and taking objective measurements for the comparison. I am not someone who is a validated trained listener, but I will also give a brief subjective opinion. First off, my setup is as...

    Any utility in manually adjusting Audyssey MultEQ? Do you think my frequency response improved?

    I have an older Marantz SR7002 which has Audyssey Multi EQ built in. Using the generic mic and auto calculated filters and then comparing it with REW and my UMIK-1 it gives me horrendous corrections in areas that certainly do not need correction. It looks like this is quite an old version of...

    Field Recorder Comparison Sony PCM-D100 vs Olympus LS-11 (vs Motu M4)

    I recently treated myself with a Sony PCM-D100. The price was just too good. Here is a quick ADC Line In comparison with my Olympus LS-11. The measurements were done in REW V5.20 RC8b with a Motu M4 using the unbalanced monitor output (Output 1 RCA) which was connected to the Topping L30 so...

    REW filters into JRiver Convolution

    I spent some time trying to figure out how to make this work, gathering information from different sources, and now that it is working, I share below if someone is interested. I am far from an expert, but this is a starting point for noobs like me. The basic idea is to make measurements with...

    First REW test with UMIK-1: weird output

    I received my UMIK-1 today and took my very first babysteps with REW. I followed the tutorials from amirm, but when I tested “check levels” it was difficult to get under -20 db SPL headroom. I added max gain to the UMIK (+16 db), and increased the volume to the limit of getting in trouble with...

    Little help neede with reading REW measurement outcome

    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...

    First REW in room Measurements. How do they look?

    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...

    Presonus Sceptre S8 (optimized) & compared to Neumann KH120

    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...

    Setting Subwoofer Phase with REW

    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...

    Genelec 8030C vs Canton Fonum 300 - In room measurements

    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...

    Critique My Measurement Setup (Panasonic XR57 AVR example)

    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...

    Focusrite Clarett 2Pre USB - quick measurements

    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...

    Help me choose between these 3 measurement interfaces!

    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...

    Is MiniDSP SHD's ADC performance in the same ballpark as RME ADI-2 Pro fs?

    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...

    Shopping for a measurement mic

    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...

    Omnitronic MM-2USB for REW

    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?
