Right, that does make sense. That range is also among the most important places where this kind of help is needed in mixing. So I'm sure it would be useful, with the caveat that the user needs to be mindful of those things you mention.

ARIA STUDIO UPDATE V0.9.3 (b518) - Free Demo Available Now + ARIA AI Companion App
ARIA Studio's free demo version is now available with no time limitations, no hearing test purchase requirements, and complete online sync capabilities.
DOWNLOADS HERE:
ARIA Studio Webpage
https://altitude.audio/aria-studio/
ARIA AI Companion App:
https://altitude.audio/aria-ai
NEW: ARIA AI COMPANION APP
Our new ARIA AI companion app is primarily intended for online sync at this stage, but we have included a host of experimental features to test on your machine. Don't expect too much from the AI system yet.
Key features:
- One-click hearing test sync - no manual file transfers needed
- Option to try ARIA without taking a hearing test
- Rule-based and AI-powered preset generation
- Integrated audio player for immediate testing
Beta registration is now available directly in ARIA AI, eliminating the web registration process. You can use ARIA Studio in demo mode without registration first, and get a serial number through the app when ready.
ABOUT THE FREE DEMO
The free demo has no time limitations and includes the full ARIA Studio experience with just a few limitations:
- HD Mode disabled
- Fixed 44.1kHz sample rate only
- No preset saving
- State resets on launch
All core functionality - the personalization engine, DSP tools, and UI - is identical to the full version.
TECHNICAL IMPROVEMENTS:
- New skins and UI refinements
- AUv2 and CLAP Support on Mac (Note: AUv2 is having mixed validation success in Logic)
- CLAP Support on Windows
- Enhanced DSP Engine with modified transforms in the post-DSP convolution engines:
- Improved inversion amount, smooth factor, max correction, and phase scaling
CRITICAL FOR WINDOWS USERS - MUST READ
WINDOWS USERS MUST COMPLETELY UNINSTALL THE PRIOR VERSION BEFORE INSTALLING THE NEW VERSION.
The ARIA library location has moved to C:\ProgramData\Altitude\product\ARIA. Please back up your data before uninstalling.
FULLSCALE HEARING TEST: APPROVED AND PENDING RELEASE
Our hearing test app has been approved by Apple and has been ready for release, but we're addressing user feedback before releasing it.
The latest update includes:
- Added Technics AZ100 and AZ80 to our calibrated device list (these offer the best measurements in our testing)
- Enhanced visual controls to hide some or all feedback during testing
- Free results access through ARIA AI – no purchase required
- Tablet view support for larger devices
Next up for the hearing test:
- Desktop versions for both Windows and Mac
- New stimuli with customizable options
- Tinnitus-friendly tones
- Higher resolution in low and mid frequencies
- Support for more devices via Roon OPRA
- Improved calibration for 2-5kHz range at < 18dB
- Exponential decay gain increases at high volumes

I find the Privacy Policy (https://altitude.audio/privacy) disappointing, especially regarding deletion, sharing and transfer of personal data. I'd expect it to clearly state that they will never sell, transfer or share your personal data to other parties or jurisdictions, and that they will immediately delete all your personal data upon request, but it doesn't.

Valid requirements. To delete your account one need not request anything, but simply click the DELETE ACCOUNT button. It's within the account view.
I think both hearing test versions in circulation have this. Though I failed to add it to the companion app, which I will get corrected.
This is the kick in the pants I needed to cough up the small fortune to get them updated. Until then, we do not share your data, nor will I. No monetization or flashy PR world hearing reports.

Thank you for your response. 
I'm not trying to tell you how to run your business, I'm just providing you with some feedback from someone who cares about privacy, and your policy verbiage raised some concerns for me. Things would be simpler if all personal data was kept locally / offline on the user's machine, but that may not be feasible with the chosen approach.

No justification needed. I actually really appreciate the time to read through that stuff and the motivation to move them up the priority list.
Keeping the data locally would take some dev, but is not an impossible modification. It might actually make the app's concurrency easier to manage. I will build the desktop hearing test with this as a starting point.

That is great to hear. Though in full transparency, I see a good amount of on-boarding and stability work still needed so this is everyone's experience. Mostly with the hearing test(s) driving results and presets in a streamlined, friction-less UX. That is where I am digging in now.
