I've added configuration files to support stereo and 44.1khz. The initial post have been updated accordingly. I strongly recommand to remove the configuration files that are inappropriate to avoid loading an unappropriate configuration file by error. For example, if you use stereo and 44.1khz...

Hi, Yes it does something similar, but the major difference is that what I propose is binaural without headtracking. Some researchers (most of researchers ?) believe that headtracking is needed to allow a good quality of binaural experience. This is quoted from https://smyth-research.com/ ...

Hello, I here propose, for possessors of headphones Gold Planar GL600, a DSP configuration usable in the free software EqualizerAPO, allowing to "mimic", at some degree, the sound that you would perceive when listening a stereo (or 7.1) system in a small/medium living room. I simply want to...

Going back to my request of being able to analyze a pratical example, can you tell me what EQ to use if I provide you an impulse response of a loudspeaker in my room ?

Well a lot of people here seems to be convinced by the theory. But why can't we have a pratical measurement with appropriate plots ? No one have this kind of measurements to be shared with mode resonances before/after EQing ?

I tend to agree with Sledge. Dandan, you say "In tandem with the level reduction there is an actual, albeit not big, increase in the rate of decay." If IIR PEQ increases the rate of decay, why it is asserted the opposite ? (EQ Does Improve Bass Decay -we all understand Decay rate implicitly...

A set of measures using two electret microphones glued together in order to make a lot of measurements with different insertion depth in the ear canal: The measurements are available here in .mdat format: https://drive.google.com/file/d/1-bpPEWHvgM7Ttj_WD2mzKiBleyre3WHY/view?usp=sharing The...

Maybe one could take a set of raw SPL responses, calculate mean and variance, calculate a new response = mean+K*sigma (K being customisable but good values would be probably 2 or 3), then taking the amplitude envelope to get something like a smoothing but without being a smoothing :p. Or apply a...

Hello Matthew, The plotted BRIR have been download from Shanon Pearce's dataset, available here: https://github.com/ShanonPearce/ASH-IR-Dataset I have taken the BRIR of the room 33 "R33" for the first plots, and I don't remember the room for the over plots (doesn't matter). Sure it's the...

I think we should investigate wether the SPL signal at one point is enough to calibrate a system. I think it may be possible that our head and ears affect the sound energy in some way that we perceive things differently from what is just measured. I think that our ears are like a...

Since then, I did not have the motivation to repeat the process more rigorously and in free field conditions (i.e., in some land, with no walls or ceilings around...). Initially, I was suspecting that the transmission of sound through bone conduction was not negligible and that it may explain...

Hi, Sorry for the long reply. Just clarifying what I plotted here : https://www.avnirvana.com/attachments/image-png.32780/ I will try to explain better the experiment, and explain what the plotted amplitudes represents. The experiment is as follow: I have a sound source in a room, in...

The problem appears on both.

You have a distortion problem. The noise level is "ok" relative to the fundamental, but your total harmonic distortion (THD) is higher than your fundamental for some frequencies, so I suspect that the problem comes from your amplifier. png file

Hi there, Can you please provide the .mdat file ? In REW, file, save measurement. Maybe we can try to figure out some things.
