    Perception of ultrasounds

    I invite you to share paper research, personal experiments, and to just link to here when another topic is getting hijacked by some discussion about high sample rate or ultrasounds making an audible difference. That way people can continue discussing here and stop making off topic posts...

    Off topic in Sound Science. the new old moderation.

    https://www.head-fi.org/articles/posting-guidelines.14048/ : My easy going moderation has resulted in "give them an inch, they'll take a mile". It has to stop for the sake of this very section and anybody who will come seeking answers in those threads. A topic is not your personal chat room...

    Win10, free solution to batch convert files including 64bit VST effects?

    pretty much all is in the title. I've spent the last years using foobar to convert my music while including hard coded EQ, replay gain, crossfeed, etc. just so that I would have the sound I wanted even on the dumbest DAP in the universe. foobar does that very well(IMO), I almost never have any...

    feedback about gears. stop doing it wrong! impedance.

    For years I've been mad when reading stuff like "this device is warm", or "those 2 amps really sound very different"... because I knew that half the time the guy was making a claim based on poor testing and even poorer understanding of what was going on. For this demo/advice/critic, I used only...

    any standard to measuring IEM's impedance?

    I do it with REW. I guess the signal can't be of fixed voltage because the most sensitive IEMs wouldn't appreciate and too small a voltage would be a problem for less sensitive stuff. so I guess setting the output to something like 90db at 1khz for the IEM and just adjusting the gain/sensi of...

    no check spelling

    for the last few days when I try to check how badly I write, I get the pop up opening and then this Quote:   I'm on firefox. 45.0.2(latest to date).     doing it 2 more times for the lolz : Error executing `aspell -a --lang=en_US --encoding=utf-8 -H --rem-sgml-check=alt <...

    frontal sounds go up instead of further in front of me with headphones. why?

    should I walk looking down when listening to music?   I don't know if this happens to many people(I do know I'm not alone), if it has to do with me or my gears, but if I take a voice and put it in mono, I never get it in front of me. instead the voice will be at an angle above me. with sounds...

    how to sound science, a messy attempt.

    “The first principle is that you must not fool yourself—and you are the easiest person to fool. “ Richard Feynman The main idea is to accept that we might not have all the cards in hand. We don't know what we don't know! So it's only rational to start on the principle that we might be...

    one post to rule them all. unless it's invisible.

    I believe we're all slowly but surely, at our own pace, getting sick and tired of repeating badly the same thing again and again to people who don't want to learn anything. so how about we try to make some cool posts addressing each typical subject? that would reduce the waste of effort toward...

    measuring a source's impedance over frequencies?

    ok the story begins badly, I don't have a multimeter. ^_^ but anyway I would like to have more than 1 value, and instead get just like for IEMs, an impedance over frequencies. for IEMs I go at it with room EQ wizard and something like this     I suspect it could also work to measure a...

    vibro veritas, measuring our IEMs like a pro with amateur budget.

    I was planning on doing this as a reviews, but there really isn't a review section for that kind of gizmo. so if there is a more fitting place for this, please moderator wherever you are, move it there .       what is it? A little acoustic coupler with a cone opening. Wait what? Ok, a...

    What's that idiot castleofargh always talking about a DAP hissing? I can't hear a thing!

        This topic is my attempt at answering that question without having to rocket science so that my mother can get a meaning out of it. and hopefully you guys too. Spoiler: You're not deaf, and I'm not a golden ear.(well that's a bummer)   I measured the volume level out of 2 DAPs in...

    windows soft to switch between audio outputs?

     when it's only about toggling between outputs in foobar I just bind some keys as shortcuts in foobar and all is good. but when I want to switch windows output, I use DefaultAudioChanger.exe, a simple exe that let me use a bind to switch between the outputs I select. it looks perfect but if the...

    does a 24bit dac use actual 16bit when reading 16bit?

    behind the question is the "problem"(not realy one) that 16bit dacs don't really have 16bit available. as some of the "paths" are used for other fuctions of the chipset.making most 16bit dacs more like 12bit dacs or something like that(don't know if there is a usual value).   so when using a...

    sorting portable gear by power levels. (vaguely or not)

    I'm flabbergasted by the ingenuity of manufacturers and how cleverly they succeed in giving specs that usually can't be used side by side with the competitors.   I don't want to make something perfect as a dap or amp behavior might differ greatly from 16ohm load to 300ohm load. but I suppose...

    less volume control in foobar with columns UI

    I'm used to set my volume by going over foobar's volume toolbar and scroll(MOUSE3). by default it's a 1db increment and I find it great to fine tune volume instead of moving the volume slider itself.  adding columns UI (I need it for other components) is now limiting the volume to 6 steps from...

    looking for an amp with good shielding against cellphones

    hi,  i would really like to forget about electromagnetic/radio/mojo interferences when commuting. after pestering some member with PMs (thx everybody) i've got a few leads but i need your help for some more peculiar demands on amps.     so my perfect amp would: -give me zero noise...

    Hello friends! need advices for new gear. no budget limit but some nerdy demands.

     i m looking for the best sounding "portable player"  that:   -1/ would boot fast! around 5sec to resume playing would be good . (no external memory or new music added, just a simple boot up+music)   -2/ can play audiobooks faster! i don't know the name of that function, it plays faster...
