Here are some itching funnies (and ready made for REW targets) I’d like to share. First, Let’s take the same set of Impulse Responses obtained by Sweeps and average* them 3 ways in REW : Frequency Dependent Windowed RMS Average, RMS Average, FDW Vector Average. I add results from Real Time Analysis of Pink Noise measured while Moving Microphone. There have been some changes between MMM and Sweeps times but still there’s a good consistency between RMS Av and MMM results while FDW RMS Av and FDW VA yield radically different results, in my room with my speakers. Hence, you’

Goal /the incumbent filters: get a faster more “agile” articulate intelligible sound while keeping big bass extension Crisis started when I switched off convolution to compare my setup + original Argo of Jamal at Alambra to the needle drop sold as dsd download (yes yes and to much praise by Acousticsounds ; meaningless comparison since I doubt the needle drop is sourced from the distorting but sometimes gloriously tubey original) : though convolved DSD was a clear winner over non convolved DSD or LP, it sounded too analog and too tamed, fat and slow. Findings

Hi, I wonder if someone could provide a step-by-step guide to achieving room correction using REW and HQ Player. I tried to find a tutorial but the information is scarce and spread all over the web... It's been years since I last used REW to measure the frequency response at the listening spot. I have a mic, REW and I'm ready to go. Thanks, Ricardo

There's Nyquist, there's the actual bandwidth limited range in relation with the actual microphones range and arguments for 192 helping reconstructing transients. However there might be a better argument for using even more space disk : multichannel even for stereo. I'm convinced that what I discovered with MCH Electric Ladyland goes far beyond eventual differences in remastering talents or marketing strategies (Bernie Grundman signs the Stereo that is soso while Eddie Kramer signs the MCH ; the latter supervised the gorgeous Mono LP Axis signed by the former who delivers a soso Mo

I'm still an audiophile when I watch TV. And my computer is now by best source for ripped movies too since I am back to the future with a Kuro 500 Plasma TV (that doesn't have the capability to process my Blu-Ray remuxes) I could do with the included in IINA (new os x player based on mpv) eQ but I want better. However I must confess I have not been able to write a correct syntax to get IINA trigger FFmpeg afir that would convolve the IR filters I have designed for HQplayer. Anyone can help?

I'm trying to get an audiophile sound when playing remux ripped blu-rays on my computer. Getting the right syntax to make afir work in FFmpeg would be a way. At the moment I follow Bob Stern's advice to try Audio Hijack to capture the audio output of my video player app and put an AU in. Allloy 2 works but I know I can beat simple eQ with my filters REW/RePhase designed for HQP. I can't get iZotope Trash nor Fog convolver to simply convolve my own 2 channels FIR. The simple but mighty old LAconvolver works and beats Alloy 2 yet. However it resamples my filters to 44.1 and I'd like to keep

I have previously posted asking how to configure JRiver to send stereo to multiple zones. I have now come up with a solution. This is the best I could manage without moving to pro audio type solution. I would still like to implement a master volume for the convolution channels but for now I guess I have to live with this setup. It was a slow progress from 2 speakers to the current 26 speakers setup. It took me 5 years to get the 4 speakers correct and last few months for the rest of the speakers. The convolution works for stereo setup too and it doesn't cost much.

The measurements of actual concert halls presented here https://pdfs.semanticscholar.org/e4c9/b3222f26472f6ba12e7fea900c2edb10c14c.pdf show a much more drastic drop of the frequencies above 5K than suggested by target curves such as B&K C, Bob Katz's or HK RR1 The bass roll-off is consistent with the FR of the monitors used while the drastic treble roll off appears to be the hall response. I recently frowned at the measurements of an expensive Audio Research amp (see Stereophile) but this, and some solutions blamed for rolloff, would it be filters cables or what have
