Hey all, I've been checking in and out the forum for quite a while but haven't made an account until now. I've been really trying to get my room acoustics the best I can, within my (spending) ability. I've always used Sonarworks, but recently I've dived into trying to learn REW. I have to...

I have a couple of these for gigs with my band. Here's the frequency response from the datasheet: Not bad, not great. I guess optimized for SPL and pairing with a sub. I played around with them and was shocked to find that the enclosure is tuned at 46 Hz. I was expecting around 80 Hz...

The Backstory So... In the last couple of days I've been messing around with some Game Boy Advance (GBA) emulators, and I've found the experience to be very frustrating. I was getting some very annoying audible crackling, and I soon gave up trying to make heads or tails of it for a couple of...

Hi, I’d like to share my latest turntable measurement procedure that I’ve been working on. It’s still under development, so I’ll focus more on describing the procedure than on the results or overall quality of the tested turntable. Any comments or suggestions are more than welcome! Tested...

Hello everyone, I’d like to measure my stereo system, which consists of two active speakers (B&O Balance). I’ve connected a Wiim Pro Plus with a 10-band parametric EQ beforehand. For the measurement, I’m using the classic combination of REW and UMIK-1. I’ve set up a test configuration, but...

Hi! I've been working on a macOS audio player focused on bit-perfect playback, and I've reached the point where I need perspectives beyond my own. This is my first post here, and I'd like to start with an open discussion about the design choices and tradeoffs I've made. If there's enough...

These are some measurements of the Apple iPod nano (7th gen) taken on a Topping E2X2 OTG via REW. The test suite was ripped from Golden Sound's REW test suite on Tidal (via an unnamed website, for convenience). The FLACs' bit depth and sample rates were verified via Spek before converting to...

Hello everyone! I would like to measure my Ortofon Music Red cartridge with an Ortofon Test Record. I tried looking in the SJPlot but this test record is not available. How would I go about measuring it? I have the recording chain already set up. This is the test record...

Hi amigos, I tried some measurements of my current system. Please put the measurements into perspective and thank you in advance for your indulgence as I am not an expert in this area. Please note that I did several listening tests before taking measurements. Several people recommended using...

I've posted this thread on the pro-audio, but I think it's better of here because it's a bit more technical :) -- Hi all, I'm the sound guy of a 7 piece rock and pop (cover)band, and I tow my system from gig to gig. I have several sets for smal gigs and bigger gigs. For smaller stages I use...

Hello, I would like to make a suggestion that DAC reviews included PCM filters responses charts, not only for single-speed sampling rates (44.1khz, 48khz) but also for double-speed (88.2khz and/or 96khz). The reason is that it seems that for some DACs, the filters' responses and efficiency are...
