Cutroom
Free · alpha · new: Studio Voice

The fast audio editor, back.

Cutroom is a free audio editor in the classic two-view layout radio producers grew up on, with the keyboard shortcuts already in your fingers. It's built for one job above all: cutting phone calls and speech, fast. And now it does the first pass for you: Auto Edit listens to a call and finds the ums, the stumbles and the dead air.

Cutroom's Auto Edit on a phone-in: cuts marked in colour on the waveform, and the review list of fillers, repeated words, a long pause and a presenter 'Yeah', each with a tick box
Auto Edit

Press one button. Get a cleaner call.

Open a phone-in and press Auto Edit. Cutroom listens to the whole call and lists every cut it would make, marked in colour on the waveform. Untick anything you want to keep, then apply them all at once, as a single undo. Recorded a voice-over instead? It does those too.

The ums and ahs

Two listens, not one: a precise one for the words, and a second that's tuned to hear the "um", "uh" and "er" a tidy transcript leaves out.

Stumbles and repeats

"I, I was", "was, was", a phrase said twice. The first try goes, the one they meant stays. A caller setting up a joke and the presenter delivering the punchline is left alone.

Dead air, tightened

Long pauses are shortened to a natural gap, and only where the call is actually quiet, so a word too soft to catch is never cut by mistake.

The presenter's "yeah" and "mm-hm"

Cutroom tells the presenter from the caller by the phone line itself, and offers to remove the presenter's "yeah"s between the caller's sentences. Where the presenter talks over the caller, it shows you, and leaves it.

Voice-overs: the breaths

Record a VO and Auto Edit hears there's only one voice. It finds the breaths between the lines and makes them 15 dB quieter, so the read still sounds natural, or cuts them out if you'd rather.

Voice-overs: the retakes

Read a line, stumble, read it again: Auto Edit spots the line said twice and keeps the last take. Ums and long gaps go too.

Safe to air: swearing

Strong swear words and slurs are found and bleeped with a tone, keeping the call the same length, or cut out if you'd rather. Milder words like "bloody" are left alone.

Safe to air: personal details

A phone number, a postcode (including Eircodes) or a house number and street read out on air are found and cut, or bleeped if you choose, so a caller's details don't go out by accident.

The bits before and after the call

"Hello, can you hear me?" at the start and "stay on the line and we'll take your details" at the end are trimmed off. Cutroom won't trim while the caller is still saying something that matters.

Levelled and cleaned up

After the cuts, the caller's phone line gets a clean-up EQ and is brought up to the presenter's level, then the whole call is normalised to −23 LUFS (or −16 or −14). It's a separate undo, so you can take it off on its own.

You stay in charge

Light, Standard or Aggressive. Nothing changes until you press Apply. Anything Cutroom isn't sure of (a lone "um" that might be a short answer, a sound nobody turned into a word) is listed but left unticked for you to hear first.

Private, and on your computer

The listening happens on your own machine, on the graphics card if there is one (Apple Silicon and Intel Macs, most Windows graphics cards) and on the processor if not. Calls are never uploaded anywhere.

The first time you use Auto Edit, Cutroom downloads its speech models, about 2.7 GB, once. It shows you the download and where the files go, and you can move them to another drive. Auto Edit is tuned for English.

Cutroom is in alpha. It's usable every day, but it's early: expect rough edges and the odd bug, keep your original recordings, and save your work often. Cutroom autosaves and recovers after a crash, but it isn't a substitute for a backup yet. Your feedback shapes what comes next.

What's new in 0.7

A voice recorded at home, made to sound like the studio.

Clean Up now does more than take the noise away. Studio Voice listens to each recording and sets the tone from it: the boom of a small room cut, the presence and air a laptop or phone mic loses put back, then compression, de-essing and a loudness for where it's going. No presets to choose and no knobs to learn. 0.7.1, from your feedback: zoom buttons you can tell apart at a glance, and Save As starts in the folder you last saved to, so a run of clips from one file all land together.

Studio Voice

Press Clean Up and it's the default: the noise comes out first, then the voice is matched to the sound of a clean studio voice, measured from your own recording. It only lifts what's really there, so a phone call's missing top end isn't turned into hiss.

De-essing that leaves your esses alone

Only the sharp esses that stick out above the voice are turned down; ordinary ones stay, so nobody ends up with a lisp.

Levelled for where it's going

−16 LUFS for podcasts and online, −23 LUFS for broadcast, or the loudness it came in at, all with a −1 dBTP true-peak ceiling. Or choose noise only and leave the tone as it was.

In Batch Process too

File > Batch Process has a Studio Voice step, so a folder of guest recordings comes out sounding like they were all done in the same room.

New in 0.6

Clean up a voice in one click, and the big-editor tools radio actually uses.

The handful of things people open a heavyweight editor for, without the weight: noise out from under a voice, clipped calls repaired, a folder of files done in one go, beds that duck by themselves, and punch-and-roll for voice-overs. 0.6.1 was a round of fixes from a check of the whole app.

Clean Up

A button beside Auto Edit. It takes the fan, the hiss, the busy room or the phone line's noise out from under a voice, with no noise print to capture first, on your own computer. Pick how much: Natural, Light, Strong or all of it, then Studio Voice or noise only. (macOS 13 or later on a Mac.)

DeClip

A caller shouting into the phone flattens the tops of the waveform. DeClip redraws them from the audio either side. It's in the Effects menu, and Auto Edit's clean-up now does it first, whenever a call is clipped.

Batch Process

File > Batch Process runs DeClip, Clean Up, an EQ preset, Studio Voice and a loudness target over a whole set of files, into a folder, never over the originals.

Export Between Cues

Record the whole phone-in hour, drop a cue at each call, and File > Export Between Cues saves each call as a file of its own, levelled if you like.

Auto-duck in the multitrack

Right-click a music bed's track and tick Duck Under Other Tracks: it dips 12 dB whenever someone's talking and comes back after, in playback and the mixdown alike. Off unless you turn it on.

Punch and Roll

Fluffed a line in a voice-over? Put the cursor before it and choose Transport > Punch and Roll: you hear three seconds of run-up, then it records from there and replaces the rest. One undo puts it back.

New in 0.5: Mic Check, Auto Edit's swearing and personal-information checks, intro and outro trimming and clean-up, and multitrack drag, colours and split. New in 0.4: live preview in the Graphic Equalizer, selections that scroll with the mouse, and Auto Edit for voice-overs. New in 0.3: Auto Edit for phone-ins. Still here from 0.2: several files open at once, full save options, tags and cues saved in the file, phone recordings (M4A) on Windows, Stretch, Generate, Spectral View and Undo History.

Every release in full

What it does

Everything you need to turn a raw call into a clean one.

Two views, the editor layout people already know: an Edit View for cutting one file to the sample, and a Multitrack View for building a package from several.

Auto Edit for calls and voice-overs

One button finds the ums, repeats, long pauses and presenter "yeah"s in a call, or the breaths and retakes in a voice-over; bleeps the swearing, takes out personal details and levels the call. Review it, then apply as one undo. Runs on your own computer.

Mic Check

Three seconds of quiet and one line read out loud, and Cutroom tells you what to change before you record: level, noise, hum, echo, pops, or a headset that sends phone-quality sound.

Shortcuts you already know

The classic editor keymap throughout: Ctrl+T trims, F8 drops a cue, F12 swaps views, H/J/K/L move the selection edges. Change any of them with Alt+K.

Sample-accurate editing

Drag past the edge and the view follows, shift-click extends the selection, right-click for the edit menu, edit one channel at a time, six clipboards, Mix Paste and Paste to New, cue markers and unlimited undo. Edits land exactly where you put them.

Long files without the wait

Audio lives on disk, not in memory, so a three-hour show opens, scrolls and edits as quickly as a ten-second call.

Broadcast-ready loudness

Normalise to EBU R128, ATSC, −16 LUFS or your own target with a true-peak ceiling, and check any file with Loudness Statistics (BS.1770-4).

The effects that matter for speech

One-click Clean Up with Studio Voice, DeClip, Delete Silence to tighten the gaps, plus Noise Reduction, a Graphic Equalizer with call presets and live preview, Dynamics, Hard Limiter, Stretch, high- and low-pass, fades and more. F2/F3 repeat the last one.

Your plugins too

VST3 effects on Windows and Mac (and Audio Units on Mac), with live preview in the Edit View or on multitrack tracks.

Multitrack packages

Tracks with volume, pan, mute, solo and a colour; beds that duck under the voice; drag in the files you have open; clips you move, trim, split and crossfade; fades and volume/pan envelopes; plugin delay compensation and a master fader.

Record straight to disk

Punch and Roll for voice-overs, no length limit, with a live waveform as you record, stereo level meters, and several armed tracks at once from different inputs. Cutroom warns you before the disk fills up.

Safe by default

Autosave every 15 seconds and crash recovery. Long jobs run in the background with a Cancel button.

Save the way you need

WAV, FLAC and MP3 with the encoder built in, at any sample rate, mono or stereo, with tags. Opens WAV, AIFF, FLAC, MP3, Ogg and M4A. Light, dark, or follow the system.
