    On Group Delay and Spatial Effects

    Er, actually, this thread should probably be in the psychoacoustics area. Can a mod move it? Introduction and observation: Following the fairly well received post on the relationship between group delay and spatial effects in headphones, I thought I'd start a new thread on the matter, gathering...

    Hifiman Ananda Review (headphone)

    I'm starting to form the hypothesis, that group delay (as well as frequency response; particularly around 8 kHz and possibly around 2 kHz - aka, the Blauert bands) is responsible for much of the out-of-head soundstage (or is it instrument separation? I dare not answer that question yet)...

    Has anyone trained a cat to do audio testing?

    For years, I put silly pictures on my lab report covers. This was one of my all-time favourites

    JBL Stage A130 Review (speaker)

    Hmm. I wonder if this also applies to the stage a130. Ah well - good things are worth waiting for, I suppose. And I'm not completely speaker (and headphone)less for the nonce.

    JBL Stage A130 Review (speaker)

    I ordered the speakers a couple of weeks or so ago from a Canadian retailer. I got an email saying, that the speakers won't be delivered to me before the thirty-first of March. The shop owner blames the plague for the delay: presumably, production can't currently meet demand due to general...

    Can the 10kHz notch on headphones be emulated with EQ?

    I've been wondering the same, and am trying to experiment with specific reverb between 7 kHz and 10.5 kHz: so far, I'ven't been able to find a reverb plugin, that can manage these parameters

    JBL Stage A130 Review (speaker)

    Based on this review, I purchased the speakers for 300 cad, thanks to a post by the Canuck, who has a list of Canuckish sellers. I currently have an old pair of Technics SB-P1000 connected to an older Denon avr in a very non-suitable listening room. Eventually, I'll get a pair of f208 - but I'm...

    Review and Measurements of New JDS Labs Atom Headphone Amp

    Last I read, he uses menuBUS and AUNBAND (I think that's what it's called) on mac. ProQ is much better tho Positive. I had not only a lengthy discush on the ProQ forum1, but hours spent trying to find the precise equation and make an easy-to-use version on a calculator app. The differences in...

    Review and Measurements of New JDS Labs Atom Headphone Amp

    Just in case you're not aware, ProQ's Q values are not the same as those provided by oratory1990: oratory1990's must be equated to ProQ's with an annoying equation, dependant on frequency, bitrate and Q value: q*(2*π*(f/b))/sin(2*π*(f/b))*√(2).This equation is seemingly only valid for peaking...

    Review and Measurements of WesionTEK Khadas Tone Board DAC

    Assuming you have both the Buffalo and the ToneBoard, have you noticed any difference between the two? I also have the Buffalo II, with Twisted Pear's 16 bit USB converter and am strongly considering getting the ToneBoard, if only to get a better USB converter.
