Trim Audio Online with Waveform Selection
Local · No uploadsTrim MP3, WAV, AAC and FLAC audio, or clips from a video with sound. Drag a precise start and end range on the waveform, export one segment or multiple segments in a batch, edit title and cover art, and send clips straight to Audio Merge. Everything runs locally in your browser without uploading the source file.
Quick Answers
- Waveform selection sets exact start and end times. The trimmer accepts MP3, WAV, AAC, FLAC and video files with an audio track.
- Single-segment mode exports one clip; multi-segment mode exports several clips or transfers them to Audio Merge in their current order.
- MP3 and FLAC output can embed title, artist and cover art. Trimming and tag writing happen locally in the browser.
How to Trim Audio on a Waveform
- 1
Upload MP3, WAV, FLAC or a video containing audio
- 2
Drag start and end handles on the waveform
- 3
Choose single or multi-segment mode, then set format, quality and tags
- 4
Export clips or send the selected segments to Audio Merge
Common Audio Trimming Uses
- Cut ringtones, alerts and short voice clips from a longer recording
- Remove silence and unwanted sections from podcasts and interviews
- Split a long audio file into chapters or independent clips
- Trim several clips, reorder them, and merge a new complete track
Audio Trim and Re-encoding Limits
- Converting to MP3 or AAC may add one generation of lossy compression
- Embedded cover art is supported for MP3 and FLAC output only
- Long-file waveform analysis and export depend on browser memory and CPU
- Video input processes audio only and does not retain video frames
How to Choose an Audio Trimmer
- vs. desktop editors: no install or timeline setup—open the waveform, trim and export
- vs. upload-based trimmers: files stay private on your device with no upload wait
- vs. basic cutters: multi-segment export, tags, cover art and direct transfer to Audio Merge are built in
How Waveform Selection and Audio Trimming Work
- The browser draws samples onto a waveform canvas and converts selection coordinates into seconds. Export uses atrim or -ss/-to to retain only the selected range.
- A matching codec may allow stream copying; changing format, re-encoding a trimmed range or adding cover art triggers a new encode at the selected quality.
- Multi-segment mode creates an independent output for each selected range and can pass all ranges to Audio Merge without another download-and-upload step.
Audio Trim, Multi-export & Merge FAQ
How do I trim an MP3 online?
Upload the MP3, drag the start and end handles on the waveform, choose MP3 output and export. You can keep the same format while changing title, artist and cover art.
How precise is waveform selection?
Selections are stored with sub-second precision. Final cut accuracy also depends on the source timebase and output encoder, which is sufficient for voice, music and ringtone clips.
Can I export multiple clips at once?
Yes. Switch to multi-segment mode, add several ranges and export each clip, or send all selected segments to Audio Merge.
Does trimming audio reduce quality?
Lossless output or stream copying avoids another lossy generation. Exporting MP3/AAC or embedding artwork requires re-encoding at the selected bitrate.
Can I edit title, artist and cover after trimming?
Yes. MP3 and FLAC output support title, artist and embedded cover art, written to the result during export.
Can I trim audio from a video?
Yes. Upload a video with audio, select a range on the waveform, and export only the chosen audio segment.
How do I merge multiple trimmed clips?
Use multi-segment mode, select all required ranges and click Send to Audio Merge. The clips are queued in order and can be reordered, trimmed again and tagged.
Which audio formats are supported?
MP3, WAV, AAC, FLAC and video files with an audio track are accepted; output supports MP3, AAC, WAV and FLAC.
