Mutal Toolkit
Tools for sound mixers
Free · In-App Purchases · Designed for iPad
Multi-country wireless coordination, script analysis, sound pads, audio slicing and playback, metadata for your rushes — script, pads and playback on the same page.
Mutal Toolkit is the production sound mixer's daily companion — one app for everything you need on set.
Frequency coordination, script reading, sound triggers, audio playback, file slicing, metadata — all connected in a single workspace, organized by project.
RF — FREQUENCY COORDINATION
Build a clean frequency plan for your entire wireless fleet in seconds. The engine scans for local broadcast transmitters, calculates intermodulation products and returns the best available frequencies — drawing from a comprehensive database of wireless devices. Share your RF setup with your team in PRO: invite collaborators by email or SMS from the project manager; transmitters, frequencies and shooting locations stay in sync across devices, with view-only or edit permissions. See supported countries at www.mutal.fr.
SCRIPT — SCRIPT READER
Drop in a PDF: dialogues, roles and scenes are detected automatically. View stats by role and by scene. Annotate, highlight, jump between scenes. Pin sound pads directly onto your script for instant playback. Full-screen mode with auto-scroll, cue system and Bluetooth foot pedal support.
TRIG — SOUND TRIGGERS
Tap-to-play sound pads with polyphony, loops, solo, mute, pan and per-pad EQ. Organize pads into banks or pin them directly onto your scripts.
PLAY — AUDIO PLAYER
Play back polyphonic audio files with markers, actions (stop, skip, cue, loop), BEXT timecode, LTC output (iPad only), auto-gain, 3-band EQ, time-stretch and vari-speed. Controllable from SCRIPT.
SLICE — AUDIO SLICER
Split recordings into selections — manually or with automatic detection. Name clips with Speech-to-Text. Export to Trig or as WAV, AIFF or M4A.
FILES (iPad only)
Inspect and edit embedded metadata from professional recorders, audition multichannel files instantly and bounce polyphonic files with configurable channel routing.
PROJECTS
Group scripts, tracks, trigger banks, RF plans and locations into projects. Import and export entire projects in one step.

more This update sharpens script and continuity reading: better detection of roles and scenes (cue numbers ignored, decimal scenes kept distinct, dialogue lines better captured), cleaner highlighting, and a new "Highlight scenes" setting. The foot-pedal page turn no longer shifts the document horizontally.
Also recalled from 1.2.20:
• Audio files with a misleading extension (an AAC named .mp3) that opened with no sound and no waveform on iOS 26: fixed in every module, with a clear message when a file cannot be opened.
• Slice: M4A export as a real AAC file; WAV/AIFF exports keep the source bit depth (16, 24 or 32-bit).
• Open in Mutal: videos accepted, and special characters in names no longer block opening; a file with the same name no longer replaces the old one on import.
• Play and Slice: markers and selections listed in time order; Play gains the arrow that renumbers markers.
• Metadata: accented notes and scenes read back correctly, takes over 4 GB and 32-bit float files supported.
• RF: when adding a location, active locations follow the "Limit DVB-T influence" setting.
1.2.21 9 Sept
This update fixes a playback issue on iOS 26: some audio files opened in Trig with no waveform and no sound. They now load correctly in every module.
Also in this release:
• Play, Slice, Trig: a clear message tells you when a file cannot be opened, instead of an empty track or a silent pad.
• Slice: M4A export now produces a real AAC file, lighter and playable everywhere, and WAV/AIFF exports keep the source file's bit depth (16, 24 or 32-bit).
• Open in Mutal: videos are accepted, and file names with special characters no longer block opening.
• Imports: a file with the same name as another one no longer replaces the old one.
• Play and Slice: markers and selections are listed in time order, and Play gets the arrow that renumbers markers.
• Metadata: accented notes and scenes are read back correctly, takes over 4 GB and 32-bit float files are supported, and editing keeps the fields it does not change.
• RF: when adding a location, active locations follow the "Limit DVB-T influence" setting (same country, same region, or single site).
• Script: scene highlights show up right at launch, without toggling DIALOG, and text added with the Text tool covers the text beneath, can be dragged, and is deleted with a long press.
1.2.20 5 Sept
This update fixes a startup hang: on some RF projects (especially all-wireless setups), the loading screen could stay stuck at launch. The app now starts reliably.
Also in this release:
• Files: improved display and handling of Cantar and Sound Devices rushes.
• Script: played pads are marked on the document, reader scrolling no longer shifts the page horizontally, and right-aligned scene numbers are detected again.
• Slice: fixed "shifted" automatic selections on multitrack files.
1.2.19 21 Aug
Script — Memos: pin notes right onto the PDF, exactly where they matter (Mutal Pro).
Script — Role colors: each character keeps its color from one script to another within a project, and you can hide a role's highlight.
Script — More reliable detection: better role recognition (merges accented/unaccented variants, no more phantom roles from "(MORE)" / "(CONT'D)" markers).
Audio output: a new picker to choose the output (system, iPad speaker, USB interface).
Take loading: a single progress bar, estimated time remaining, and a Cancel button.
Various fixes and stability improvements.
1.2.18 9 Jul
New: every receiver group can be given an adjustable min/max frequency range, in addition to the span.
On the RF side: opens straight on the Frequencies tab, and the correct country is detected for a point added by GPS coordinates.
Play & Slice: the track tag on the waveform shows the right name again.
Stability: various RF display fixes on iPad.
1.2.17 2 Jul
- Play — Revised Timecode section: the start timecode stays stable when you change the frame rate (fps), and your settings apply on the fly. Tap the timecode bar to open it directly (iPad).
- Play — Generated LTC follows the playback speed, and elapsed/remaining time now show the real duration based on that speed.
- Files — Folder cloning is now reliable: source size, available space at the destination, overwrite confirmation, and a progress bar that protects the copy.
- Files — Export a track: only the selected track is exported, with its name and metadata (timecode included). Track count and names now display correctly for poly files.
- Files — Bounce: keeps the timecode and metadata (fps, scene, take), and track panning follows the Cantar matrix (Pan Cantar / Pan auto toggle).
- Files — Open a PDF directly in the iOS system PDF viewer.
- Script — Dialogue detection now ignores revision marks (“*”) in the margin of revised scripts.
- Various fixes and stability improvements.
1.2.16 30 Jun
Script — New (iPad), by popular request: Script and Play side by side in split view (landscape) to follow the text while controlling playback.
Team sync — New: "Apple account sync" keeps an RF project in sync across all your devices on the same Apple account, without inviting a collaborator.
RF — Better country detection for GPS places (a neighboring country was sometimes picked near borders or offline) and the real country now shows in the list.
Files — Polyphonic Cantar rushes (.AAN folders) now list every take separately, with the routing matrix (iPad and Mac).
Projects — Fix: renaming an open project could erase your Slice tab selections. Fixed, and already-affected projects repair themselves on load.
Stability (iPhone) — Fix: reopening the app after a long time in the background could get it stuck on a looping loading screen.
Team sync — Read-only collaborators can't wipe frequencies anymore: RF editing is locked, browsing stays free.
1.2.15 23 Jun
- Pro — 7-day free trial: try all Pro features before you commit.
- Trig — Fixed a bug where a pad could stay silent (animation playing but no sound) after a phone call, Siri, or plugging in headphones. Sound now resumes without restarting the app.
- Trig — Larger export window on iPhone and iPad, with a fully scrollable file preview.
1.2.14 17 Jun
- Important — Fixed the project list disappearing after the 1.2.12 update: your projects (still on your device) are automatically found and restored.
- Script — Two new role color palettes: "Flashy" (neon tones) and "Custom", with an editor to set each of the 16 colors exactly the way you want.
- Script — Redesigned role color picker: the 16 colors of the active palette are offered as presets, with built-in palette switching and access to the free color selector.
- Script — "Scene selection" export now truly exports only the chosen scenes: other scenes sharing the same pages are masked out.
- Script — Parentheticals after a character name — (CONT'D), (ON THE PHONE)… — are no longer highlighted with the name.
- Slice & Play — Fixed a bug that could leave selections silent after reopening a project (audio file imported from Files or an SD card).
- Reliability — Free mode no longer deletes any data: pads, selections, markers and PDFs beyond the limits are set aside and fully restored when you return to Pro.
- Reliability — Safer project imports (no more incomplete projects if interrupted) and better recovery from damaged files (Script documents, RF databases).
1.2.13 12 Jun
- Mac availability — Mutal Toolkit now runs on Apple Silicon Macs (M1 and later).
- Script — Richer annotation: tools now available on iPhone (highlighter, underline, strikethrough, mask, pens), a new Text tool to add a line highlighted in the role's colour, and multi-line highlighting in a single swipe.
- Slice & Play — Unified, richer WAV exports: mono/stereo choice, sample rate (44.1 / 48 / 96 kHz), gain & EQ baking, original format preserved.
- Trig — Export a bank to WAV with output-channel choice, sample rate and gain/EQ.
- Trig — More reliable long-press pad reordering: smoother jiggle and dragging (iPhone and iPad).
- Trig — Pad settings (gain, EQ, crop…) are now properly saved and restored within projects.
- Trig — Panning a stereo pad left/right now produces a true mono reduction.
- Slice — "Load in Play" now sends the whole file instead of a selection.
- Fix — Resolved an issue that could revert an RF setup to Free mode (5 frequencies, 1 location) for some Pro subscribers at launch.
1.2.12 10 Jun

- Script — Parenthetical stage directions are no longer highlighted; the annotation highlighter now matches the automatic highlight colors; refreshed reader controls.
- Trig — New full-screen pads mode with a simple control bar (iPhone).
- Trig — Looped playback no longer drops out when you turn loop on mid-play or adjust a looping pad's crop.
- Slice & Play — No more duplicate selection or marker under the playhead; new items keep a unique color after a deletion.
1.2.11 4 Jun
- Slice & Play (iPad landscape) — New Shortcut Bar with editable notes.
- Polyphonic / multi-channel files — Each track is now named on the waveform, single-channel view is sharper, and you can switch channels during playback without stopping.
- Render — Applies gain, EQ and channel selection in a single pass and keeps your track names.
- Memory safety — Files too large for your device are now blocked with a clear message instead of crashing.
- Slice & Play — Zoom and waveform position preserved across tabs.
- RF — A device's country version now follows your location; cleaner PDF export.
- iPhone — Smoother waveform scrolling, polyphonic support, refined toolbar.
1.2.10 29 May
- RF engine — Fix: when relaxation is enabled, the deep-search fallback now respects the level you've chosen. It used to silently fall back to Standard, which could leave a saturated plan without a solution.
- Team Sync — Reliability, battery life and multi-device behaviour improved. On shared projects, RF sync now pauses when you're working in another module and resumes instantly when you open RF.
- Trig — Polished the CROP editor: clearer selection handles, more readable playhead, and a new "Open in Slice" button that hands the file (with your crop bounds) over to the Slice module.
- Slice & Play — Transport buttons (PLAY/STOP and lock) refreshed
1.2.9 25 May
New! Define custom playback bounds for any Trig pad — non-destructive. Drag two handles on the waveform in the new CROP section (iPhone) or CROP tab (iPad) to set Start and End points without altering the source audio.
New since 1.2.7 : Share your RF transmitter list and the entire RF module with your team. Your frequencies and shooting locations stay synchronized with your collaborators, who can view and/or edit your RF rig. Invite them to collaborate on your project by email or SMS from the project manager.
- Trig — Pad color changes now update the pad's mini waveform and the CROP section waveform instantly (iPad and iPhone).
- RF — Critical fix: the engine no longer moves a locked frequency or proposes a duplicate against a locked device.
- RF (iPhone) — Manual frequency entry: the popover no longer dismisses when the iOS keyboard appears, even for devices at the bottom of a long list.
- RF (iPhone) — Custom transmitter creation now available (iPad parity): plan, bandwidth, equal spacing, high-density mode, and more.
- RF — Dual color picker in every edit sheet: "Device color" and "Model color" side by side.
- RF — Group selection menus now display occupancy ("Group #1 / 4 devices") and a group keeps its name when a device leaves it.
- Sync — "Frequencies per location" mode: single-location selection is now correctly enforced on collaborators' devices.
- Sync — Locations imported via an RF scan (RF Explorer, tinySA…) now appear on collaborators' devices with their name, country and full spectral data.
- Sync — Shared projects now appear automatically on all your devices using the same Apple ID via iCloud, no need to re-open the invitation link on each device.
- Sync — Fixed a regression where joining a shared project as a write collaborator could overwrite the owner's data with an empty state.
- Help — New entry "CROP — playback bounds" in the Trig help section, with full workflow walkthrough.
1.2.8 23 May
New! Share your RF transmitter list and the entire RF module with your team. Your frequencies and shooting locations stay synchronized with your collaborators, who can view and/or edit your RF rig. Invite them to collaborate on your project by email or SMS from the project manager.

- App — Lower energy use on iPhone: animation timers and sync polling suspended when the app goes to background.
1.2.7 21 May
- RF — Australia: histogram fills instantly when activating a location (bundled TNT data), then ACMA enriches in the background
- RF — Scan import: country pre-selected automatically based on device locale
- RF — On a location coming from a scan import, DAB+ bands no longer appear while predicted TNT bands stay hidden (iPhone + iPad consistency)
- iPhone — Script: pads placed on the PDF no longer jump to the right when placing / clearing the cue, or starting autoscroll in reader mode
- iPhone — Trig: Play / Stop button in the pad edit sheet to preview settings without closing the sheet
- iPhone — RF: scan-imported locations stay visible across quit/relaunch
- App — update detection reworked: check on every launch in addition to the 24-hour throttle, "Up to date " pill on the Check button, HTTP cache bypassed
1.2.6 18 May
Sennheiser Spectera (WMAS):
• Frequency planning fully reworked: Spectera blocks
are placed in their own pass, without interfering
with the other devices. Faster and more reliable.
• 1.4 GHz bands unlocked for the US (Part 74 + AFTRCC),
the UK, Belgium, Norway, Denmark, Cyprus, Lithuania
and Brazil (Sennheiser LIC Zone 16).
• Default Spectera version now follows the region:
UHF-EU in Europe, UHF-US in the Americas.
iPhone:
• RF Locations view: the keyboard no longer covers
the "Decor name" field or the city search.
• The active RF sub-tab is remembered across visits.
Fixes:
• No more false-positive "2TX intermodulation"
warnings on Spectera blocks (they don't take part
in IMD calculations by design).
1.2.5 11 May
This update extends support for
Sennheiser Spectera transmitters (WMAS,
UHF and 1G4) and brings many improvements
to frequency management, the Bluetooth
pedal, and the iPhone experience.
What's new
- Full support for Sennheiser Spectera
(WMAS) in UHF and 1G4.
- Bluetooth pedal now available on
iPhone, with three modes (Script, Trig,
Play) and the ability to swap the
buttons.
- Redesigned page-turn: one press to move
to the next page, with a few lines of
overlap to keep your bearings.
- Smarter frequency calculation: an
automatic deeper search if the standard
one fails, plus a third even-deeper
level on demand.
- Frequencies-per-location mode: device
state (active, version, antenna) is now
remembered per location.
iPhone improvements
- RF histogram at parity with iPad.
- VHF bands toggle now actually honored
by the planner.
- Automatic device naming aligned with
the iPad behavior.
- Add Device: models are now grouped by
generation.
- Add Device: category filters (Bodypack,
Handheld, Plug-on, IEM…) and a colored
icon in front of each model.
Settings and comfort
- "Check" button and app version now
shown at the bottom of Settings.
- Discord link added to the About panel.
- The main Stop button now also stops
the Files audio preview.
- "Frequency bands" page in the PDF
export reworked: device names now sit
legibly below each colored bar.

- Anguilla and Jamaica moved to the
ATSC 6 MHz grid.
1.2.4 9 May
Added new DPA N-BP1 and N-HH1
Added the Shure SLX-D+ series
RF improvements:
• PMSE bands refactored from official declarations by
national regulators (EFIS, May 2026) for the 46 CEPT
countries.
• Frequencies-by-site mode: changing the region
deactivates active sites outside it; French DAB+
blocks reappear when returning to FR.
Other fixes:
• Trig on iPhone: Pan (L/C/R) button on each pad.
• RF settings: "Allow VHF bands" off by default
(can still be enabled manually).
• Script: better dialogue attribution when two scenes
start on the same page.
• Help / About: version and build shown dynamically.
1.2.3 6 May
Minor bug fixes
1.2.2 30 Apr
This update fixes and improves:
• Files: native iOS preview is once again used for PDF and
audio files (WAV, MP3, AIFF, AAC, M4A). To open a file in
Mutal Toolkit, use Share → Mutal Toolkit instead.
• RF iPhone, Histogram: tapping a band no longer auto-opens the
TX Info panel. The "TX Info" button is back in the toolbar
(and mirrored on the right when the grid overflows), and the
details now appear in a half-to-full-screen bottom sheet.
• First launch: removed the "Open your files in Mutal Toolkit"
alert that appeared after the splash.
• Pro subscription: new "I have a promo code" button to redeem
a code directly within the app.

• General optimizations: snappier response, lower memory footprint, and various fixes.
Thanks for the feedback — keep it coming at contact@mutal.fr
1.02 28 Apr
This update sharpens script and continuity reading: better detection of roles and scenes (cue numbers ignored, decimal scenes kept distinct, dialogue lines better captured), cleaner highlighting, and a new "Highlight scenes" setting. The foot-pedal page turn no longer shifts the document horizontally.
Also recalled from 1.2.20:
• Audio files with a misleading extension (an AAC named .mp3) that opened with no sound and no waveform on iOS 26: fixed in every module, with a clear message when a file cannot be opened.
• Slice: M4A export as a real AAC file; WAV/AIFF exports keep the source bit depth (16, 24 or 32-bit).
• Open in Mutal: videos accepted, and special characters in names no longer block opening; a file with the same name no longer replaces the old one on import.
• Play and Slice: markers and selections listed in time order; Play gains the arrow that renumbers markers.
• Metadata: accented notes and scenes read back correctly, takes over 4 GB and 32-bit float files supported.
• RF: when adding a location, active locations follow the "Limit DVB-T influence" setting.
