Audio Jitter Simulator, OpenSource application to bake jitter into an audio-file

This is a small open-source Python program you can use to bake jitter into an audio-file (For testing- or educational- purposes, fun, or to simply color a piece of music, or whatever else you want of course:) )

Link to Github where you can find the free software:

https://github.com/JELSTUDIO/JEL_Audio-Jitter-Simulator

There is both the open-source Python-script (Which you can pip-install manually, and even modify and create your own fork from if you want) and a ready-to-run SC (Self-contained).exe file for Windows (If you don't know your way around Github; look to the right, and a bit down, for a green text that says "Latest")

If you use the manual Python-install method remember to install the requirements as it needs to have some dependencies installed, but the procedure is explained on the github-page (If you've never tried installing Python-software locally it might seem a bit daunting, but it isn't really. All you need to have is Python which you can find for free on the Microsoft-store. I used Python 3.13 when building this, so get that one if you haven't got it already, or you can try adjusting the installation to your preferred version of Python, if you feel comfortable doing so, as other versions may work just as well)

No matter whether you use the Python-script or the exe-file, the way you use the program is exactly the same:

When you run it it opens a GUI with which you can load a mono or stereo wave-file (I am not sure if this file-format can be used on other operating-systems than Windows)

Then you can select between these 3 jitter-presets:

High-End DAC (100 ns)

Consumer Grade hardware (1 µs)

Vintage Gear (5 µs)

There is an additional jitter multiplier (0.5x to 5x) which allows you to exaggerate or reduce the effect beyond the preset value.

Then when you click "Apply Jitter" the software will use the CPU to re-sample the audio and then save a new wave-file (In the same directory you loaded the audio-file from) with the same name 'appendixed' with "_jittered".

The new file will be the same bit-depth and sample-rate as the original, but now have the selected jitter-errors baked into it.

To comply with this gearspace forum-rule:

"Regarding software, if you wish to discuss super deep-dive things like nulling, PluginDoctor analysis etc. please create a new thread in Music Computers. You can share a link to your new thread in the relevant NPA announcement for others that are interested in such discussions."

I believe technical debates about jitter should not be had in this thread (I don't personally mind, but I guess this forum-rule means it should better be done in a different post, so I'm mentioning it just to be on the safe side:) )

I verified the code-behavior with Microsoft's Copilot (Which is basically a version of ChatGPT directly accessible in Windows) and X's Grok, and they both verify that the code bakes in correct jitter-behavior at realistic values for the 3 different types of hardware.

The reason I built this software was really only so I could empirically see myself exactly what jitter does and does not do (Since it seems to be a much discussed topic around the glorious internet with all its anonymous "I know more than you do!" experts everywhere:facepalm::deth::hit:)

But after playing with it I thought it might be more widely useful to more people, so I released it.

The specific type of coloring of the audio, that it does, is perhaps a thing that could be useful for something more than just fun and games. It's subtle, but it does actually sound interesting when exaggerated a bit (A slightly kind of de-focused sound, that perhaps can be good for some types of music or projects)

Anyway, it's available now, for those who may be interested:)

(It's MIT-licensed, so have fun)
