CHU 2 Studio 0.1.1

Fixes the app not starting after you download it. Everyone hitting version 0.1.0 should take this one.

Windows marks every file unzipped from a downloaded file as "came from the internet". The Microsoft .NET runtime then refuses to load one of the app's own files, and 0.1.0 died with RuntimeError: Failed to resolve Python.Runtime.Loader.Initialize. The app now clears that mark from its own files before it opens the window. Checked on a real build with all 269 files marked: it starts, and it clears them.

Also new since 0.1.0: the app has an icon (C² on navy), and the README shows the app.

Install

No installer, no admin rights, no driver. Windows 10 or 11, 64-bit.

What it does

Tune the EQ inside your Moondrop CHU 2 DSP earphones. The EQ is stored in the earphones, so after Save it plays everywhere: phone, console, any PC, with no app running.

• Quick Tune — five ready sounds (Music, Gaming, Movies, Competitive FPS, Calls), a strength control, and tweaks in plain words.
• Build PEQ — the chip's five bands on a graph you can drag, undo and redo included.
• Hear before you save — changes play at once; nothing is written until you press Save.
• Import and share — AutoEq, Equalizer APO and Peace files, plus short share codes.
• Your original EQ is kept safe — the first connection saves it on your PC; "Restore original" puts it back.

CHU 2 Studio 0.1.0

Do not use this version. It does not start after you download it: Windows marks the unzipped
files as coming from the internet, and .NET then refuses to load one of the app's own files
(RuntimeError: Failed to resolve Python.Runtime.Loader.Initialize).
Use 0.1.1, which fixes it.

Tune the EQ inside your Moondrop CHU 2 DSP earphones, from Windows. The EQ is stored in the earphones, so after Save it plays everywhere: phone, console, any PC, with no app running.

In this first release

• Quick Tune — five ready sounds (Music, Gaming, Movies, Competitive FPS, Calls), a strength control, and tweaks in plain words such as "Cleaner bass" or "Less sharp cymbals".
• Build PEQ — the chip's five bands on a graph you can drag, with numbers you can type, undo and redo.
• Hear before you save — changes play at once; nothing reaches the earphones until you press Save.
• Import and share — AutoEq, Equalizer APO and Peace files in and out (it keeps the five biggest filters), plus short share codes.
• Presets — a library, your own saved EQs, favourites.
• Your original EQ is kept safe — the first connection saves it on your PC, and "Restore original" puts it back.
• Five themes, an About page with the licences, and a log file for support.

Good to know

• Saving restarts the earphones for about a second; the sound stops during that.
• The chip has no volume control, so a boost can distort. The app lowers the whole EQ by the size of the biggest boost, which makes it quieter — turn your volume up when you compare.
• Unsaved changes are lost when you unplug; the saved EQ comes back.
• It changes what you hear, not your microphone.

Tested on

One real CHU 2 DSP on Windows 11: first save, save after an import, unplug and replug, and Restore original all read back correctly. The five Quick Tune sounds were checked by ear. 262 automated tests pass.
