LABS BETA PROGRAM

Labs is where we build and test our next-generation audio tools before release. By joining the program, you get early access to products in development and help shape their future. All we ask is your feedback — what works, what doesn't, and what you'd love to see.

ARIA ONE is full-spectrum sound personalization software for macOS, Windows, iOS, and Android, built from your unique hearing profile. It brings together everything Altitude Audio has developed into a single connected system:

• FullScale Hearing Test — Built-in full-spectrum hearing test with Instant, Quick Results, and Full Accuracy pathways
• High-Resolution Hearing Correction — FIR-based correction derived directly from your hearing profile
• Adaptive Multi-Stage Lookahead Limiting — Loudness control and peak management across frequency bands
• AI Personalization — ARIA AI helps generate presets, guide setup, answer questions, and refine your sound over time
• Cross-Device Sync — Keep presets and hearing profiles in sync across all your devices
• Built-In Audio Player — Playback, personalization, and sound control inside one listening environment

On desktop, ARIA ONE is available as standalone software and in VST3 and AUv3 plugin formats. It offers both a Simple View for everyday listening and an Advanced View with full DSP control, multi-band editors, stereo processing modes, analysis tools, and macro controls.

• Early access to ARIA ONE and all features in development
• NFR (Not For Resale) license while testing
• Direct influence on product development

The ARIA Studio closed beta is no longer accepting new registrations. However, all of the ARIA Studio DSP engine, hearing correction, and personalization features are now built into ARIA ONE.

Download ARIA ONE through the Labs beta program below, register for the beta within the app, and you'll have full access to the complete system.

ARIA ONE is built for mobile from the ground up — the same hearing test, hearing correction, AI personalization, cross-device sync, and audio player run on iOS and Android.

Mobile is free. Desktop beta downloads are live now. iOS is live now via TestFlight. Android is live now via Google Play open testing.

ARIA ONE is built for audiophiles, pro audio users, and serious music listeners. For this audience, dependable media player performance is a basic requirement.

Mobile today is an interim release. It puts ARIA ONE in listeners' hands now.

Bespoke player builds are the next step toward the full vision.
