Trim, merge, convert and denoise sound. Extract audio from video. Works offline
adTrim is a fast, private audio cutter and audio editor. Trim a section out of any audio file, join several clips into one track, convert between MP3, M4A and WAV, pull the audio out of a video and reduce background noise, all on your phone, with no account and no uploads. WHAT YOU CAN DO • Trim audio: drag the two ends on the waveform to keep only the part you want. Ideal for cutting a lecture, an interview, a podcast or a voice message. • Extract audio from video: turn an MP4 or MOV into an audio file in one tap. • Convert audio: switch between M4A, MP3 and WAV. • Merge audio: join several audio files into one track, trim each clip first, and split a recording into parts to keep only what you need. • Noise reduction: remove background noise from a recording, then compare before and after. • Voice memo clean-up: cut the silence at the start and end and reduce noise in a single step. PRECISE, NOT FIDDLY Drag the handles for a rough cut, then fine-tune with a jog bar down to a tenth of a second. Whenever you adjust a cut point, adTrim plays the audio around it, so you can hear whether it is right instead of guessing. PRIVATE BY DESIGN Everything runs on your device. Your audio and video files are never uploaded. adTrim needs no account. The free version shows ads, and the app collects anonymous usage data to improve itself. ALL TOOLS INCLUDED Every tool, including Merge, Noise reduction and Voice memo clean-up, is included. No subscription and no in-app purchases. SUPPORTED FORMATS Audio: MP3, M4A, WAV. Video: MP4, MOV, M4V, 3GP, AVI, MKV. Save the result as M4A or MP3 and share it anywhere. adTrim is available in English, Vietnamese, Spanish, Portuguese, French, German, Japanese and Korean, with light and dark themes.
