LABS BETA PROGRAM

The formal beta has concluded — ARIA ONE remains available to download below

Program Update

The formal ARIA ONE Labs beta program has concluded, and formal beta licenses for ARIA ONE and the Altitude Limiter are no longer being issued while we focus on shipping release builds. This page stays up as a reference — the current release remains free to download below, and existing testers can find data & sync guidance here.

Labs is where we build and test our next-generation audio tools before release. The formal ARIA ONE Labs beta has now concluded as we focus on shipping release builds, so we're no longer issuing formal beta licenses. The current release of ARIA ONE remains available to download below.

Currently in Labs: ARIA ONE

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.

Thank you to our Labs testers:

The feedback and insight from Labs testers shaped ARIA ONE into what it is today. Formal beta licenses are no longer being issued, but the current release stays free to download while we finalize the full public launch.

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 builds are available now. iOS is available via TestFlight. Android is available via Google Play.

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.

Sync & Your Data: What to Know

Keeping your data intact across beta phases and into production is a priority. Here's how hearing profiles and presets are handled as we move from older Labs-branded beta builds into the ARIA ONE release line — useful if you tested earlier builds.

Hearing Profiles

Your hearing profiles carry forward everywhere. Profiles created in older Labs beta builds, current ARIA ONE beta builds, or the full production release of ARIA ONE are the same data, stored the same way, and synced the same way. There is no migration step — your hearing profile is yours across every version.

Presets

As we transition users from older Labs-branded beta builds into ARIA ONE, presets will move to a new table. Before leaving a Labs-branded build, complete a sync so your local devices match the beta server. After installing ARIA ONE, complete a batch sync to upload your presets to the ARIA ONE tables. This covers all presets except for per-device mood slot presets.

Mood Slot Presets

Per-device mood slot presets are a specialized class of preset tied to individual device endpoints. To bring these into the new ARIA ONE namespace, we will either provide a utility script or build a dedicated sync mechanism for this specific preset type. Either way, no mood data will be lost.

We'll share detailed transition instructions on Discord and in-app before any migration window opens.
