From first listen to handoff
A review with a clear finish.
Stereo or immersive, streaming target or broadcast spec, the workflow is the same. It ends with a reviewed mix, not a folder of voice memos.
01Load the mix.
Open your master and listen with loudness and the selected delivery target in view.
Start listening- 02
Mark the moment.
Press N while listening. Your note keeps the timecode, severity and status, saved on your Mac.
Leave your first note - 03
Return a clear report.
Notes and measurements go out as a one-click email report your client can act on, or export the review for your next step.
Prepare your handoff
See Player Pro in action.
A complete local workflow for listening, verification, revision notes, immersive review, and client-ready reports.
Six of eight delivery targets are stereo or broadcast.
Load a plain two-channel WAV and you get the full review workflow: the same loudness engine, timecoded notes, phase and spectrum analysis, A/B compare, exports and email report. Only the 7.1.4 Speaker Room and the 3D Object Visualizer are immersive-specific.
Stereo in. Email report out.
Load a plain two-channel WAV and Pro selects Engine v2 automatically. Loudness, timecoded notes, phase, spectrum, A/B compare and export all stay in the same review window.
Enter sender and recipient, then press Send. Your client receives an HTML email report with the notes, exact timecodes, severities, loudness figures and a screenshot of the review window.
Eight delivery targets. One badge.
Pick your target and the Integrated LUFS card compares your measurement against that platform’s LUFS and True Peak ceiling, then shows Pass / Warn / Fail. Range, Short-term, True Peak, Short-term Max and Momentary Max sit underneath.
Per-channel PPM for all twelve channels with OVER indicators, polled continuously. Reset clears the Integrated measurement and re-accumulates from now. Export Report writes the loudness compliance report as PDF.
| Target | LUFS | True Peak | Kind |
|---|---|---|---|
| Apple Music | −16 | −1 dBTP | Stereo |
| Spotify | −14 | −1 dBTP | Stereo |
| YouTube | −14 | −1 dBTP | Stereo |
| Amazon Music | −14 | −2 dBTP | Stereo |
| EBU R128 | −23 | −1 dBTP | Broadcast |
| ATSC A/85 | −24 | −2 dBTP | Broadcast |
| Atmos Music | −18 | −1 dBTP | Immersive |
| Netflix Atmos | −27 (±2 LU, BS.1770-1) | −2 dBTP | Immersive |
Press N. It’s already written down.
Notes that are already timecoded.
- Point Note: press N during playback. The note lands at the exact playhead time and opens for editing. Playback never stops.
- Range Note: drag a region on the timeline, press Enter. The note is attached to that span, not a single instant.
- Severity: Critical (red) or Minor (cyan). Status: click to cycle Open, Checking, Done.
- General Note for impressions that aren’t tied to a timecode. Search and filter by text, status or severity. Undo and redo with ⌘Z / ⇧⌘Z.
- There is no Save button. Every note is written to a local database the moment you finish editing it. Quit, come back next week, load the same file: notes, statuses, severities and the General Note are exactly where you left them.
One click. Your client gets a report, not a voice memo.
Fill sender and recipient, press Send. The recipient receives an HTML report with your notes, timecodes, severities, loudness figures and a screenshot of the window.
- CSV export, respecting your current filters.
- JSON export with the full note data, including General Note, platform target and measurements.
- PDF loudness compliance report.
- DAW Markers (.mid): standard SMF markers plus a matching .txt, importable into Logic and Pro Tools. Set the BPM field to your song tempo so markers land precisely.
Phase, spectrum, and an honest A/B.
Analytics that catch what ears miss.
- Phase Correlation, −1 to +1. Near +1 is mono-compatible; near 0 is wide, normal for immersive; negative, especially ≤ −0.3, is out of phase: go listen in mono.
- Spectrum: 31-band real-time energy.
- A/B Compare: load a second file as B and switch while playing with the \ key. UTUVO aligns B automatically and shows the offset in ms or samples. Notes taken while B is active are tagged B.
The details engineers actually notice.
- Switch output device during playback without stopping.
- Sample-rate match indicator: the chip describes the file, and next to it the app compares the file rate with the rate your output device is actually running. Green dot means matched; amber tells you when macOS is resampling your output, with the device rate on hover. It deliberately does not claim more than the nominal rate.
- Timecode frame-rate chip, read from the file’s Dolby metadata. Green matches the Dolby Atmos Music delivery spec (24 fps is a MUST); amber does not; grey means the file states no frame rate, unverified rather than a pass.
- Two-layer waveform: a light peak outline over a solid RMS core. The gap is your crest factor at a glance.
- Soft-clip limiter and ±dB output trim, double-click to zero.
- Locked Range + Loop: drag a region, hit loop, and that section repeats while you work on it.
When the file is immersive, Pro is the high-end mode.
Twelve channels, one glance, every one soloable.
The 7.1.4 Speaker Room lays out L / R / C / LFE / Ls / Rs / Lrs / Rrs / Ltf / Rtf / Ltr / Rtr in their spatial positions, with Solo and Mute per speaker.
- Group pills (Front / Side / Rear / Top / LFE) select a whole tier at once, and Shift-click adds across groups.
- Speaker glow: while playing, each speaker lights up with the level of its own channel. Off / Subtle / Standard / Strong.
- Metering is taken before mute, so the PPM keeps showing source levels while you audition a single speaker.
Watch 41 objects move through the room.
For ADM masters, a separate window renders Atmos objects moving in real 3D space, with the speaker layout, the screen plane and the listener position drawn in. Object labels toggle on and off.
Hear it the way your listener will.
| Render mode | What it does |
|---|---|
| Multichannel | Raw channels straight through, for a real speaker array |
| Spatial Audio | AirPods head-tracked spatial audio, the official Apple algorithm that Apple Music uses |
| Binaural | HRTF binaural for any headphones, no AirPods needed |
| Stereo Downmix | Dolby standard-coefficient downmix for plain stereo |
Turn your head. The mix stays where the picture is.
Choose Spatial Audio and the soundfield stays anchored to your screen as you move. Works with any AirPods that support Spatial Audio: AirPods 3, AirPods 4, AirPods Pro, AirPods Max. Tested on AirPods Pro and AirPods Max.
It looks like it belongs in your studio, in your language.
Eight themes, eight languages.
Themes: UTUVO Light · UTUVO Dark · Daylight · Midnight · Spotify Green · Ableton Grey · Graphite Teal · Apple Classic. Switch from the top bar; recolours instantly.
Languages: English · 繁體中文 · 简体中文 · 日本語 · 한국어 · Deutsch · Français · Español. The interface translates instantly; audio terms like LUFS, True Peak and Loop stay in English by convention.
Everything stays on your Mac.
Notes are written to a local database as you work. Reopen the same file and Pro restores the General Note, point and range notes, timecodes, severities and statuses.
The shipping-build receipt for this image records a full quit and relaunch with all three notes and the General Note intact.

Asked often enough.
Is there a download link?
Yes. The current public build is signed, notarized and stapled. Double-click the DMG, drag UTUVO Player Pro into the Applications folder, then open it from there. The first launch is offline. The version number and the exact SHA-256 are on the Downloads page, taken from the release record so they cannot go stale here.
Does it ship for iOS?
No iOS build. UTUVO Player Pro runs on macOS only.
Can I send notes by email?
Yes, as one of four output paths. Sending uploads the note text, loudness readings and one screenshot to UTUVO’s own endpoint (api.utuvo.app/send-notes), not a third party.
Does MIDI export keep my Chinese notes?
MIDI has no Traditional Chinese encoding, so marker names are ASCII (index + summary). The full Chinese text lives in the .txt sidecar.
How does the 30-day trial work without a card?
Download and open the app to evaluate all features for 30 days. No credit card or account is required. The trial does not turn into an automatic charge; purchasing is a separate decision.
Does a perpetual licence include every future version?
It includes the major version you purchase and every update released within that major version. A future major version may be a separate optional one-time purchase or may be free. It is never charged automatically. If you buy within 30 calendar days before a new major becomes available, that new major is included at no charge.
I replaced my Mac. How do I move my licence?
Open the app on the old Mac, go to Settings and deactivate the licence there, then enter the same key on the new Mac. No email needed, and a licence covers 3 of your own Macs. Deactivate while the old Mac still has a network connection: if it is offline at that moment the app clears the licence locally but the seat can stay held on our side, and support@utuvo.app can release it for you.
Which macOS version is required? Does it run on Intel?
The current download requires macOS 13.0 or later · Apple Silicon only. Apple Silicon only; no Intel or Windows build. Try it on your working Mac before deciding to buy.
How do the 30-day trial and 14-day refund period differ?
The 30-day full-feature trial is for evaluation before purchase. The 14-calendar-day no-reason refund period begins separately on the purchase date, so trial days do not reduce it. After 14 days, a simple change of mind is generally not refundable, while transaction errors, activation failure, nonconformity and statutory remedies remain covered.
How do I request a refund or get support?
Email support@utuvo.app. Within 14 days of purchase you can request a full refund without giving a reason; include your order number or licence key, or use the link in your order confirmation email. For a product issue, include the app version, macOS version and steps to reproduce it.
Will offline use or a verification outage stop my paid app?
No. After a paid licence is successfully activated, it continues to work offline on that device. A network or verification-service failure alone cannot deactivate it. If the verification service permanently ends, we will provide a free way for lawful perpetual-licence holders to continue using, reinstalling and activating on a replacement compatible Mac within their device count.

These tools come from someone who uses them to deliver every day.
UTUVO is built by one person: Micky Yang.
He's a Tonmeister with 1,600+ Mandopop songs mixed in Dolby Atmos, four Golden Melody Awards for recording, and he teaches recording at university. Most tools are what engineers imagine recordists need. UTUVO is what a recordist built because he couldn't stand the existing ones.
- 4× Golden Melody Awards (Taiwan's Grammys) for recording
- Apple Music made him an official engineer playlist: "Micky Yang: The Engineers"
- Game scores: NetEase's Onmyoji, Harry Potter: Magic Awakened
- 1,000+ Chinese pop string sessions
