Run the studio
The business OS for the studio.
Invoicing, expenses, and accountant access — the half of the job that doesn't happen in the DAW, folded into the same tool that ships the music.

Rivers — Master v3
Unlocked when this invoice was marked paid.
Branded invoices
Your logo, tax ID, address, and bank details on every invoice. Auto-incrementing numbers. PDF letterhead. Multi-currency (AUD / USD / EUR / GBP).
Quotes
Separate workflow from invoices, separate numbering. Statuses: draft, sent, accepted, declined, expired. Convert an accepted quote into an invoice when the work is done.
Invoice → audio gate
Tick a box on the invoice form to lock the linked song. The share page shows a paywall instead of audio until you mark the invoice paid; then it unlocks automatically.
Receipts & expenses
Eighteen tax-ready categories — studio rent, equipment, software, professional services, subscriptions, more. Photograph the receipt, pick a bucket, done.
Accountant share-link
Save your accountant's email; Levels Flow generates a long token URL. They open /accountant-view in their browser and see invoices, quotes, and receipts read-only.
Persistent client portal
Invite a client once. Every project, every song, every version you've ever delivered them lives behind their login. The “can you resend?” email goes away.
Storage included
5 GB on Free, 1 TB on Studio, 5 TB on Pro, custom on Enterprise. Audio sits inside Levels Flow with row-level security. Drop the Drive plan.
Deliver to clients
How the song gets to the client.
Share links and portals built for the way clients actually work — on their phone, in the back of an Uber, three months after the session.
Public share links
One link per song or project. No client account required. They open it, listen, comment at exact timestamps, and download the file.
Time-limited share links
Studio+Set an expiry date when you create the link. After expiry the share page reads as expired without exposing the audio.
Watermarked previews
ProOn Pro, share pages can play a watermarked MP3 with an audible voiceover (“Demo for {Client}”) every 30 seconds instead of the full master.
Share-link uploads
External engineers — mastering houses, mix engineers — can upload a version back through the share link without an account. Their upload appears in your song page immediately.
Approve-final stamp
Studio+Clients press “Approve final” on a version. Levels Flow records name, email, IP, user agent, timestamp. Approved versions are protected from deletion.
Persistent client portal login
Same pitch as above, from the client's side: one invite, persistent login, all their music in one tab. No re-share, no re-upload.
Email triage
AI-filtered email, in your studio.
Forward your music inbox to a Levels Flow alias. The model keeps audio attachments, ZIPs of stems, splits PDFs, and mix notes — and discards the rest. What's left lands on the Email tab inside the app, ready to download or attach to the matching song.
Forwarding alias
ProEvery Pro plan gets an address like ab12cd34ef56@in.levelsflow.app. Auto-forward your music inbox from Gmail or Outlook, or BCC the alias on outgoing client mail — anything that lands there runs through the filter.
AI music classifier
ProTwo-stage filter: deterministic rules catch the obvious music attachments at zero cost, then Claude Haiku takes the ambiguous ones — no-name ZIPs, plain-text mix notes, splits PDFs. Newsletters and personal mail get dropped before they reach you.
Direct downloads
ProAudio files and ZIP packages land on the Email tab as signed URLs you can download right inside Levels Flow. No client app, no Gmail attachment rabbit hole, no quota for the file you needed at 11pm.
Auto-link to song
ProWhen the model can guess the song from the subject, body, or filename, the drop arrives pre-attached to the matching song page. Otherwise you pick the song from a dropdown — one click, then it's filed.
Sender + timestamp audit
ProEvery drop carries the sender's name, email, subject, and received-at timestamp so you can prove what landed when, from whom — useful for splits disputes and revision arguments.
Discard with one click
ProAnything that snuck through the filter — marketing, personal, the wrong attachment — gets soft-deleted with one click. The row stays in the audit log; the file goes nowhere.
Review & comments
Versions, waveform, comments — one screen.
A single-pane reviewer for every song: pick a version, see the waveform, leave timestamped notes. Same screen for the studio and the client.
Version pills
Masters, mixes, demos, instrumentals, custom types — each gets its own labelled row. Click a pill to swap; comments and metadata update with it.
Multi-format collapse
WAV, MP3, and FLAC of the same logical version collapse into one pill. The download modal exposes every format individually.
Timestamped comments
Click anywhere on the waveform to drop a comment at that second. Comments scope to the active version; clicking one jumps the player to that timestamp.
Keyboard shortcuts
Spacebar plays / pauses. Number keys 1–9 jump to the version named with that number, scoped to the cluster you're listening in (masters or mixes).
Level-match A/B
When a song has loudness measurements, a toggle plays louder versions at a softer volume so A/B comparisons are fair instead of just louder = better.
Stems package handling
Versions with type “stems” (or a .zip filename) render as a non-playable card with a download CTA — no broken waveform, no decode error.
Audio engineering
Numbers that actually matter.
Loudness, peaks, and platform compliance — measured on every upload, surfaced where the engineer needs them.

Auto loudness analysis on upload
Every uploaded mix is analysed on ingest: integrated LUFS (ITU-R BS.1770), true-peak dBTP, and RMS. Numbers appear on the version chip before the client opens the link.
Mastering target check
Per-platform spec check: Spotify, Apple Music, Tidal, YouTube Music, broadcast, club. Green or red against each, no ambiguity.
Pre-master checklist
Studio+Surfaces a quick sanity sheet to the client before they sign off — peaks under -1 dBTP, integrated LUFS in range for the chosen platform, no clipping.
All formats supported
Upload WAV, AIFF, FLAC, MP3, M4A, OGG, or ZIP for stems packages. Loudness analysis runs on every uploaded mix automatically.
Stem delivery flags
Per-file flags for TV mix, instrumental, and a cappella. The label travels with the file so the right asset lands in the right slot when you deliver.
Catalog & metadata
Catalog every release once.
ISRC, ISWC, BPM, key, genre, mood — capture once on the song page, reuse on splits, exports, and your studio profile.
Clients → Projects → Songs
Three-level tree in the sidebar. Auto-expands to wherever you are; recents pinned above so you're one click from yesterday's session.
Release metadata
Per-song fields: ISRC, ISWC, BPM, key, genre, language, mood tags, recording date, release date, publisher, copyright owner, sync flags. All optional.
Splits sheet
Studio+Capture contributors with role, PRO affiliation, publisher, and percentage. Live total — must hit 100% to lock. Lock generates a printable PDF.
E-signed splits
ProOnce the splits row is locked, contributors sign electronically. Locked splits show signature timestamps next to each contributor.
Genre + mood tagging
Curated genre picker plus free-text mood tags. Surfaced on your studio profile and feeds search inside the app.
Global search
Search across clients, projects, songs, comments, and tags. Keyboard-first; results group by entity type so the right one is always at the top.
Collaboration
When it's not just you.
For the projects that need a second engineer, a session producer, or a client kept in the loop without giving them a seat.

Project invites with roles
Bring collaborators onto a single project with a defined role: engineer, producer, A&R, observer. Roles map to read/write scope automatically.
Collaborations hub
Top-level page that lists every project you've been invited to alongside the projects you own. One inbox for the whole working week.
Internal task tracker
Lightweight requests inside a project — “upload stems for track 3”, “re-export with louder vocal”. Not a full PM tool; just enough to stop using DMs.
Notifications
Activity from comments, approvals, share-link uploads, and invoice events lands in a single notifications drawer. Email digests opt-in.
That's the toolkit. Ship your next session with it.
Free during beta. No credit card. Your clients still don't need an account.
