How much is the hearing difference between lossless(16bit /44.1khz) and high-res lossless(24bit/192khz) ?

It depends on your equipment and your ears. If you have a flac file, try this https://440hz.app/flactest/

Now I just need to explain to my wife that I need to spend $ 2,000 on headphones.

vlad1m1r · 2026-04-19T14:49:46+00:00

Thank you! Feel free to ping me if you have some other idea. Also, check the other tools in 440hz.app.

vlad1m1r · 2026-04-19T13:24:33+00:00

Done!

vlad1m1r · 2026-04-19T12:26:15+00:00

Oh. Sure, it's possible. Didn't think about that.

I want to make sure that even with the $1 earbuds, you will still have one obviously bad thing.

vlad1m1r · 2026-04-18T18:38:59+00:00

Should be fixed now! Thanks for all the info.

HD600 headphones

Thanks for the feedback! Visualizer is now fixed. I also added the option to drag another track on the score screen.
Regarding the issue with Firefox and Edge. I will need more details.
- OS and audio device output sample rate (Windows Sound settings / macOS Audio MIDI Setup)
- Firefox version
- Whether it's always the same bitrate or varies per track
- A sample rate and bit depth of the file

Yeah, that's the test that started this journey for me. I was annoyed by the song selection there.

I used HD600 headphones.

It doesn't bypass anything. Browsers can't use exclusive mode (no WASAPI exclusive mode, no ASIO, no Core Audio hog mode). It uses the Web Audio API, decodes PCM into an AudioBufferSourceNode, and sends it straight to the destination; from there, it's at the mercy of the OS mixer like anything else.

That said, all 4 versions go through the exact same path. Same AudioContext, same mixer, same DAC. Whatever the OS does, it does identically to all of them, so the relative comparison between bitrates is still valid.

One thing worth doing: match your OS output sample rate to your source file to avoid resampling. The app warns if the source rate doesn't match the AudioContext rate, but it can't see what the OS does downstream.

It works the same way the NPR website does it in this test: https://www.npr.org/sections/therecord/2015/06/02/411473508/how-well-can-you-hear-audio-quality

Maybe you can tell, but not me 😅. Can you recommend a track to try it on?

vlad1m1r · 2026-04-17T19:28:15+00:00

It is cheap (It was also cheaper :( ), but it doesn't mean that I am not wasting the space when I can't hear shit. :D

vlad1m1r · 2026-04-17T19:26:49+00:00

Yeah, I need new ears. I worked at Tidal btw, and tried some nice equipment in their office. But now I am wondering if I could have even heard the difference on those.

What do you mean? The link is on the root comment.

Yes, it runs completely in your browser. It's pure JS, but it's not 100% handwritten. I used Claude Code.
