Beta Test: DISTORT - audibility of distortions

any headphone amp with dc protection.

Here is a test version to see if your DC issue is resolved. Please download and install version 1.0.21 (not officially released yet):

https://distortaudio.org/DistortSetup21.zip

There are some big differences in how the screen is laid out, all the distortion-related settings are now on the left, in a table. The one that controls DC is DC Removal = On or Off. To clear all settings (probably a good idea the first time you use this version) press the red X above the table:

Please try this out and let me know if it helps.

Note: the old version you were using also removed DC, but only when saving the distorted file to disk, not when playing it directly from DISTORT.

Here's the before and after example with 32 tone multi-tone test signal in version 1.0.21. As I said, DC was already removed properly for saved WAV files in the previous versions of DISTORT. Only playing the distorted waveform from inside the app could result in significant DC, which is now corrected with the DC Removal setting.

Maybe if you raise the price you can compete with SETs ;)
 
I'm planning a 100x price increase in the near future ;)
Make it draw tremendous power and wear out frequently, and you have something!
 
Are there plans to implement the GedLee Metric into the Multitone Analyzer test app?
Probably the wrong thread for Multitone questions :) Are there any examples where the application of GedLee metric actually produced a useful result (outside of the original papers)?
 
This is such a cool program and exactly what i've been looking for. When I import my own wav files though, they play back in mono even though its set to "Stereo". Any idea what might be going on? It will export the distorted file as a stereo file which plays back correctly in another player.

Same file is played back in DISTORT that is saved to disk, so other than some non-standard output driver channel mapping, I can't imagine why it wouldn't play stereo.
 
I was using PKharmonic, but I started using Distort yesterday. It's very amazing! Although it can't be applied to streaming like YouTube music in real time, and it's a bit cumbersome to have to apply to the songs you want by track, it still provides a much more stable and satisfying experience. Thanks @pkane
 
Distort is very good.
But sometimes, Makes the stereo file mono. (wav, flac)

And if i export L+R and Stereo options alternately several times, it will be made normally in L+R.

Version is 1.0.19
 
Hello!
Judging by the date of the messages, the program is abandoned, but I'll ask anyway. Are there plans to simulate other distortions of acoustic systems, for example, speaker phase, group delay? Maybe the attenuation time is like at waterfalls?
It would also be interesting to test the effect of phase on the scene by generating point-like apparent sound sources. Sweep generator at different points of the scene, the sounds of which should remain the same size and not move in space.
 
Its is viable to do the 32-tone multitone test on speakers like in DAC/AMPs?

Well, it’s not abandoned, just in a good place :) I’ve implemented all the things I planned to implement.

While acoustic simulations are interesting, they are probably best left for another app. DISTORT was designed to simulate common electronic distortions, and while phase and group delay may still make sense in it, waterfalls and space/scene generation do not.
