Link. And tell me what you think. Note: It may work with other cans, too, but vanilla PortaPro should theoretically be best. Edit: EQs should be turned off, and it should be quite loud.

If you did the maths, I would implement it in foobar... You may need to look at volterra filters, by the way. Among others. I also don't think performance is a problem; we live in 2008. A very strong requirement would be that the necessary measurement equipment (in-ear mics) is sufficiently...

As a few of your know, I've been on some kind of "personal mission" to get the best possible sound out of these 30 dollars... and here's where I'm at right now. Since I'm a computer scientist, all you need is an unmodded PortaPro and a decent sound card. I've wrapped up a small configuration...

I made a mistake when I uploaded the delta-corrected Filters/foobar last time. You cannot use a mono wav for stereo convolver (you need two different stereo files), otherwise the stereo separation is halved and the changes are applied two times (I didn't notice that b/c I was in a hurry with...

Some of you may have wondered why there's another DSP in the chain of the updated foobar package and why I haven't just posted the changed filters. This is because I took the Koss Filter 3 as a baseline and EQ'd some of its issues with the CurveEQ (with the help of the K701 and a few movie...

I invested a few hours with the CurveEQ and could significantly improve the sound. In head-to-head comparison to how it's now, the regular Koss seems to sound more often than not like some kind of toilet bowl with built-in speakers. :-) Though I must admit that my music choice may be a bit...

Good to hear that you're trying it out. I use DH1, but the firm setting (it doesn't annoy me at all and gives me more lower bass). As for the optimum, what I mean is that there must be a setting which, on average, cannot be further improved by changing the EQ parameters. I think this is what...

@Henmyr: Thank you very much for your initial feedback. That seems to indicate that this is applicable to KSC75's, too. Do these phones really sound so much brighter than PPros? I'd like to know if the PPro still sounds so muffled when its directly connected to the X-Fi and all Windows EQs are...

Quote: Originally Posted by HFat No comments? Let's bump this. We wouldn't want to disappoint sound_man again. Let's start with a couple questions: you seem to be saying that there's some kind of synergy between EQ and DH. Is there a reason for that? To me, they're very different...

This is an attempt at making your Koss phones sound (arguably a lot) more natural. And I mean unmodded phones, because this is simply the only way to get consistent results. I started a thread about this some time ago, but I got almost no feedback from you. But since I'm speaking of a purely...

@OP: Do you know Sampling Theory? http://en.wikipedia.org/wiki/Nyquist...mpling_theorem That theorem says that any signal which does not contain frequencies >= 22050 Hz can be reconstructed _perfectly_ from a time series sampled at 44100 Hz. This is what makes digital media possible in the...

@OP: Yeah, that was pretty good timing! :-) I hope that someone lends you his/her phones for measurement. As you say, the distortion peak is relatively narrow, but still it should be quite audible since its at -20db. Quote: Originally Posted by Liver how did you apply your inverse...

Ok. I'm a bit shocked concerning how bad the distortion of the Koss @ 4KHz is... maybe I should finally go ahead and look for some new phones ;-) Some time ago I wrote a program which reads these frequency response plots (headroom-style) and creates an inverse filter (basically an...

This is a purely digital (signal processing-based) modification to the PortaPro sound, so you'll need a PC for this. But still this is not strictly computers-as-source because you don't need a computer as a playback device, just as a number cruncher. Side note: Actually, this would also work...
