Audio Trimmer
Upload audio, preview the waveform, drag the trim range, and export a clean MP3 or WAV clip from your browser. This free audio trimmer also works as an MP3 cutter, MP3 trimmer, and audio clipper for hooks, loops, voice notes, samples, podcast clips, and music demos. It does not use CreateMusicAI credits.
Drop audio to trim online
Choose MP3, WAV, M4A, AAC, OGG, FLAC, WebM, or Opus. The audio trimmer decodes, cuts, and exports the file locally in your browser, so a quick MP3 cutter task stays private.

How to trim audio online
Cut a song, voice note, sample, podcast moment, or demo in three steps. The audio trimmer gives you a waveform MP3 cutter and audio cutter workflow without opening a desktop editor.
Upload audio
Drop an MP3 or another common audio format. The audio trimmer loads the waveform locally so you can see the full track before making a cut or using it to trim MP3 clips.
Choose start and end
Drag the highlighted waveform region, pull either edge to resize it, or type exact time values. Use it as an MP3 cutter when you need a hook, intro, outro, loop, or speaking clip.
Export the clip
Preview the selection, trim audio in the browser, then export a fresh MP3 or WAV clip for sharing, practice, production, lessons, podcast edits, or quick delivery. The exported file can be renamed, archived, or sent onward with the rest of your project notes.
A free audio trimmer for quick music edits
CreateMusicAI adds a free audio trimmer for the practical moments after recording, exporting, downloading, or preparing audio. Use the MP3 cutter or online audio cutter workflow when you only need a clean cut before sharing, mastering, splitting stems, or generating the next idea.
Use an audio trimmer in the browser
The audio trimmer works locally, so short edits, loops, voice notes, demos, podcast clips, and samples can be prepared without a server upload. For everyday file editing, it gives you a fast MP3 cutter and audio clipper in the same browser tab.
See the waveform before cutting
Waveform preview makes it easier to find silence, intros, hooks, drops, outro tails, breaths, applause, and the exact moment you want to keep before the audio trimmer exports a new clip. This is useful when the visual shape of the track matters: a quiet lead-in, a sudden chorus, a spoken pause, or a noisy tail can all be spotted before you export.
Set exact trim times
Use drag handles for speed or type precise start and end times when you need a repeatable edit for lessons, samples, demos, social clips, or delivery. This MP3 trimmer workflow is built for exact short sections.
Continue into music tools
After the audio trimmer creates your clip, move to AI music generation, AI mastering, or stem splitting when the file needs creative work beyond cutting. The MP3 cutter and audio cutter steps stay free and separate from credits.
Who uses an online audio trimmer
Use the audio trimmer whenever an audio file needs a shorter section, tighter intro, cleaner ending, or smaller clip before the next workflow. It is also a simple MP3 cutter for creator audio and music drafts.
Content creators
Use the audio trimmer to cut intros, podcast moments, voiceovers, social clips, reaction audio, and sound bites before posting or sending for review. The MP3 cutter export is ready for lightweight sharing.
Independent artists
Trim demos, hooks, rehearsal takes, reference mixes, rough masters, and quick ideas before sharing or mastering. The audio trimmer helps independent artists keep only the strongest section. A cleaner short clip is easier to send to bandmates, clients, labels, collaborators, or mastering engineers without moving the full session file.
Podcasters and educators
Prepare short lesson audio, interview clips, classroom examples, voice notes, and feedback snippets without opening a full editor. The waveform MP3 cutter keeps timing decisions clear.
Producers and DJs
Cut loops, edits, set notes, mashup sections, transition ideas, and samples before arranging, splitting stems, or building new tracks. The audio trimmer keeps the edit fast.
Audio trimmer FAQ
Quick answers about audio trimmer privacy, MP3 cutter exports, credits, waveform selection, browser compatibility, and how this free tool fits CreateMusicAI workflows.
Is this audio trimmer free?
Yes. The audio trimmer is a free browser tool and does not spend CreateMusicAI credits. You can use it as an MP3 cutter for simple edits, while credits stay reserved for AI generation, mastering, stem separation, and other server-side music workflows.
Can I use it as an MP3 cutter?
Yes. Upload an MP3, choose the part you want to keep, preview the waveform selection, and export the selected audio as MP3 or WAV. The audio trimmer also works as an MP3 trimmer and supports other browser-decodable audio formats.
Does the audio trimmer upload my file?
No. The current audio trimmer workflow decodes, previews, cuts, and encodes audio in your browser. That means a quick MP3 cutter job can stay local instead of being uploaded to a server.
What format does it export?
The current export options are MP3 and WAV. MP3 works well for lightweight sharing, while WAV is useful when you want an uncompressed clip for editing, practice, lessons, podcast snippets, or production handoffs.
Why does a file fail to load?
Browser audio decoding support varies by format and codec. If a file fails in the audio trimmer, export it as a standard MP3, WAV, or M4A and upload again. Very long files may also take more memory, so shorter exports usually give the browser a smoother editing experience.
What should I do after trimming audio?
Use the clip directly, or continue into AI mastering, AI stem splitter, or the AI music generator when you need polish, separation, or new music. The MP3 cutter task remains the free first step.
