01 — The tool
Online Audio Cutter for MP3, WAV, M4A and FLAC
Use the free Loudness.ai Audio Cutter to trim MP3, WAV, M4A or FLAC recordings and keep the passage you need. Trim a song intro, extract an interview answer or shorten a voice note. The waveform shows where sound starts and stops; selection handles and time fields let you place both boundaries precisely.
This online audio trimmer saves the selected passage as a separate WAV file. Your original stays intact. Add fade in or fade out when the clip needs a gradual opening or ending, and listen before exporting. For an MP3 version of your finished clip, use the Audio Converter.
02 — How it works
How to cut audio online for free
Open your recording
Choose an MP3, WAV, M4A, FLAC or another supported audio file. Play the recording to locate the passage, then zoom into the waveform when a boundary needs a closer look.
Set the start and end
Drag the handles or enter exact times. To make a 15-second clip from the passage at 30 seconds, set Start to 00:30.000 and End to 00:45.000.
Preview and export the clip
Play the selection, check for clipped words or notes, and adjust either edge. Set any fades you need, choose 16-bit or 24-bit WAV and click Export clip.
03 — Practical uses
Trim songs, podcast clips and voice recordings
Song cutter for music excerpts
Keep a chorus, instrumental phrase or rehearsal passage. Listen to the final note's decay so the cut does not interrupt it. Use a short fade when an excerpt ends mid-song.
Podcast highlights
Extract a complete answer for a teaser or social clip. Leave a little space around speech, especially the first consonant. Use the Audio Splitter when one interview needs several separate clips.
Voiceover edits
Remove the wait before a take or the unused sound after it. Trim WAV narration to the section required by your video editor, without changing the recording's pitch or playback speed.
04 — Frequently asked questions
Audio Cutter questions
Does the MP3 cutter download MP3 files?
The cutter opens MP3 recordings and exports the selected section as WAV. Choose 16-bit or 24-bit WAV in Format. Convert the downloaded clip to MP3 when you need a smaller file for sharing.
Can I remove a section from the middle?
The cutter keeps one continuous selection. To work with several passages, split the recording into clips, keep the pieces you want, and arrange them with the Audio Joiner.
Will cutting audio change its pitch?
Trimming changes which part of the recording is saved, not its pitch or speed. Fade controls adjust volume near the clip's edges. Compare the start and end before downloading.
Can I cut audio for free without signing up?
Yes. Open the audio cutter in your browser, choose a recording and export the clip without an account. The download creates a new file rather than replacing the original.
