Audio Trimmer.
Drag the handles to mark a region, add smooth fades, then keep the selection or cut it out. Perfect clips and ringtones in seconds.
TIMELINE MAP
Clip Boundary Editor
Turn one long waveform into deliberate boundaries. The visual emphasizes the selection, transition and resulting edit so that timing decisions remain obvious before anything is rendered.

- Long source file
Start with the right material
Short clips, podcast cleanup, ringtone excerpts and removing unwanted starts or endings.
- Set cut and fades
Understand the transformation
The chosen sample ranges are copied locally, faded if requested and encoded into the selected export.
- Trimmed clip
Verify the usable result
A trimmed or cut-out audio file using the visible selection boundaries.
Where this workflow stops
Compressed exports are re-encoded. WAV avoids lossy encoding but may quantize a higher-bit-depth source to 16-bit, and edits are limited by available device memory.
Make the final decision by ear
- Zoom into every boundary and listen across it, not only inside it.
- Leave intentional handles when another editor will continue the work.
- Verify exact duration and ordering after the final render.
How to trim audio online
- Drop an audio file into the upload box — the waveform appears instantly.
- Drag the start and end handles to mark your region; exact times and selection length are shown below the waveform.
- Choose Keep selection or Remove selection, and add fade in / fade out if you want smooth edges.
- Press Preview selection to check the cut, then download it as WAV or 320 kbps MP3.
This audio trimmer and MP3 cutter is built around a visual waveform, so you cut by sight and sound rather than typing timestamps: spikes show where the drop hits, silence shows where the take ends. Remove mode deletes the selected region and stitches the remainder together with a short crossfade, useful for cutting a cough out of a podcast or an ad out of a recording. Processing runs on your device, and selected files are not uploaded to AudioWrench.
Typical jobs: ringtones from a chorus, intro clips for streams, tight voice-over takes, sample chopping and shortening voice memos. To glue several clips together afterwards, hand the pieces to the Audio Joiner.
Audio Trimmer: quick answer and technical limits
Quick answer: A waveform editor for keeping or removing a selected time range, with optional fades at the cut edges.
- Best for
- Short clips, podcast cleanup, ringtone excerpts and removing unwanted starts or endings.
- How it works
- The chosen sample ranges are copied locally, faded if requested and encoded into the selected export.
- What you get
- A trimmed or cut-out audio file using the visible selection boundaries.
Know before you use it: Compressed exports are re-encoded. WAV avoids lossy encoding but may quantize a higher-bit-depth source to 16-bit, and edits are limited by available device memory.
Public browser workflow evidence
Question: Can the real waveform handles keep exactly 1.00–3.00 seconds of a four-segment fixture and exclude the authored outer tone segments from the downloaded WAV?
Observed result: The visible handles selected 1.00–3.00 seconds and exported an exact 2.00-second PCM16 WAV (192,044 bytes) containing the 330/440 Hz middle segments with no measured 220/660 Hz leakage.
Evidence boundary: This case covers keep-selection with zero fades and pointer-position handles. Remove mode, fades and touch-specific gestures remain outside this wave.
Network observation: No audio-payload or cross-origin requests were observed during this published workflow.
