I built an Ultimate Audio Enhancer userscript

[u/Additional_Worker731]

I built a userscript that improves audio quality directly in the browser.

Ultimate Audio Enhancer adds real-time:

• 10-band equalizer
• Bass & treble boost
• AutoEq headphone profiles
• Volume boost
• DFX audio enhancement
• Reverb, echo, chorus & other effects
• Stereo / 3D surround enhancement
• High-pass & low-pass filters
• Configurable limiter
• Custom presets
• Support for audio and videos across many websites

It runs through Tampermonkey/Violentmonkey and doesn't require separate audio software or a virtual audio cable.

I've been developing and optimizing it for a while and would appreciate feedback, especially regarding sound quality, performance and compatibility on different websites.

Can't wait for these types of insanely busy AI product images to die out 👍

You mean you prompted an LLM? You didn't make anything.

[u/LeadLerner → u/[deleted]]

That's not nearly the same. You tested out a script that you didn't make.

[u/LeadLerner → u/[deleted]]

You did not make this. It's not development. You put hardly any effort into this.

Even by AI slop standards, this is puke, did you prompt your LLM for extra sick on top of something

Slops on slops

ultimate

uses percentages for gain

ok dude

[u/Additional_Worker731 → u/cheater00]

I’ve updated it in v1.0.8.

You can now toggle the Gain & Boost display between % and dB directly in the UI.

• Volume Boost now shows the proper logarithmic dB equivalent
• Bass Boost can be displayed in dB
• Treble Boost can be displayed in dB
• The internal processing hasn’t changed — this is mainly a cleaner and more audio-friendly way to display the values

So if you prefer dB, you can now use that instead of percentages.

Only seems to work in chrome not safari.

[u/Additional_Worker731 → u/cnassaney]

Sorry about that. Ultimate Audio Enhancer is only supported on Chrome/Chromium-based browsers.

Safari is not supported, and I currently don’t plan to add Safari support because the script relies on browser APIs and userscript behavior that work differently there.

Unfortunately, there’s not much I can do about that at the moment.
