Free tools for your next audio edit
Cut a voice recording, song excerpt, or sound effect down to the section you need. Choose an MP3 or WAV, set the start and end, then preview and download your trimmed WAV. Your audio stays in this browser.
Your audio file stays in this browser for trimming. Nothing is uploaded by this tool. Export is 48 kHz, 16-bit PCM WAV; original metadata is not copied.
Three steps, one useful excerpt
Start with a recording you are allowed to edit. Keep an untouched original so you can change the cut later.
Select a mono or stereo recording no longer than 5 minutes and no larger than 50 MiB. The browser reads the file locally and shows its duration and a waveform overview.
Enter times in seconds or adjust the two sliders. Keep a little breathing room around words, notes, and effects. The selection duration and WAV size update as you edit.
Prepare the WAV, play the selection, and listen to both cut edges. Download that same WAV when the boundaries sound right. Change the times to make a different version.
A time edit, with clear boundaries
A useful audio cut begins just before the sound you need and ends after it has finished. For speech, that includes the first consonant and the end of the last word. For a sound effect, it includes the initial hit and the decay that makes the sound recognizable. A waveform helps locate activity, but listening tells you whether the excerpt makes sense.
The optional 5 ms fade softens the very edges of the exported clip. It can reduce an abrupt cut click, but it cannot repair distortion inside the recording. Disable it when you need to keep a transient at the exact boundary, or move the cut slightly earlier so the fade happens before the sound you want.
This editor makes one continuous excerpt. It does not join clips, remove a section from the middle, change tempo, or cut a video. Use a multitrack or video editor for those jobs. For overlapping sounds inside the selected time range, try voice isolation or a sound effect extraction workflow.
Know your download
Your selection is exported as 48 kHz, 16-bit PCM WAV, keeping mono or stereo from the decoded recording. The browser may resample the source. This tool does not preserve the original compressed MP3 bytes or encode a new MP3.
WAV is uncompressed here. A short WAV can be larger than a longer MP3. The panel shows the output size and asks for a shorter selection if it would exceed 50 MiB. Use the audio file size calculator to compare export settings.
Your file and cut are held in browser memory for this session. Reloading or closing the page clears the editor. Save the WAV to your device and keep notes of the original start time if you will align the excerpt with a longer recording.
Choose the hardest overlap, preserve context, and compare results from the same original.
A few useful answers
Yes. Trimming, previewing, and downloading the WAV are free and do not require an account. Saturalabs’ separate AI audio isolation service has its own account and credit flow; using this trimmer does not start a separation job.
You can open an MP3, but this tool exports a 48 kHz, 16-bit PCM WAV. It does not encode MP3. WAV can be larger than the source MP3, so check the displayed output size rather than assuming a shorter clip is a smaller file.
The trimmer reads and edits your selected file locally in this browser. It does not upload the audio to Saturalabs. Keep your original file and download your cut before leaving or reloading the page; the editor does not save your recording for later.
This editor accepts mono or stereo MP3 and WAV recordings up to 50 MiB and 5 minutes. A WAV container can hold different audio codecs, and browser support varies. Try a standard PCM WAV or MP3 export, or a shorter recording if your device runs out of memory.
Trimming keeps one time range of the complete mix. Every sound inside that range remains. To separate a voice, instrument, or unwanted sound that overlaps the wanted audio, use one of Saturalabs’ AI audio tools after preparing your clip.
The file is decoded and exported as 48 kHz, 16-bit PCM WAV, so this is not a bit-for-bit cut of the source file. The optional 5 ms edge fades change the first and last few samples. Original tags, artwork, and other metadata are not copied.
