SpeechTrim: Cut Editor
Waveform editor for speech
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
SpeechTrim is a cut editor for people who talk on camera or into a microphone. It measures your recording in 40-millisecond steps, draws the real decibel curve on screen, and lets you drag the cut threshold across it with your finger. Tightening a 30-second clip for your feed and tightening a two-hour lecture are the same three moves.
WHY IT IS NOT A ONE-BUTTON TOOL
• The waveform is the control, not decoration: drag the threshold and the cut list changes live
• Auto Threshold measures the actual noise floor of your room and places the line for you
• Smart Tighten keeps a natural pause of the length you choose instead of butt-joining every gap
• Separate minimum-silence and speech-edge padding controls, down to the millisecond
• Every cut is listed with its timecode and can be switched off on its own
• Zoom and scrub the timeline, jump straight to any single cut
• A/B the original against the processed version at the same position in the content
FILLER WORDS, ON DEVICE
Turn on filler-word detection and SpeechTrim runs a Core ML speech model with word-level timestamps, in 15 recording languages. Long recordings are processed in overlapping 50-second chunks and de-duplicated, so a two-hour lecture is handled the same way as a 30-second clip. The model downloads once, then works with no network at all.
MADE FOR PEOPLE WHO TALK
Vertical clips, podcast episodes, lecture recordings, voiceovers, interviews: the job is the same, keep the talking and lose the dead weight. Presets for short-form video, podcasts, lectures and interviews set your starting point, and you adjust from there. Export keeps the original resolution and frame rate, so a clip goes straight from here into whatever you post it with.
HOW IT WORKS
1. Import a video or audio file from Photos or Files.
2. Set the threshold by hand, or let Auto Threshold do it, and review the marked gaps.
3. Listen to the result, then export at original quality.
NOTHING LEAVES YOUR IPHONE
Analysis, filler detection, preview and export all run on device. Your recording is never uploaded, and the export keeps the original quality. Video import uses the system picker, so the app never asks for access to your whole photo library.
FREE AND PRO
Importing, editing and previewing are free, with no time limit. Pro unlocks unlimited exports and filler-word removal, as a monthly or yearly subscription or a one-time lifetime purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the period ends; manage them in your Apple ID settings.
