What is an Audio Cutter?
An audio cutter lets you extract exactly the part you need from any audio file — a chorus from a song for a ringtone, a highlight from a podcast, a loop for music production, or a quote from an interview for Instagram Reels. Unlike server-based tools, AudioTrick processes everything in your browser — your file never leaves your device.
After trimming, speed it up for a time-lapse effect or reverse your trimmed clip for a creative reveal. All free, all in the browser.
How to Trim Audio Online
- Upload your audio — drop an MP3, WAV, OGG, FLAC, or M4A file (up to 50 MB).
- Select the region — drag the start and end handles on the waveform to select exactly the part you want. Use the time inputs for precision, or press play to preview your selection.
- Export as MP3 — hit Export MP3 to download your trimmed audio as a 320 kbps MP3 file.
Precise Selection with Visual Waveform
The visual waveform shows the loudness of your audio over time, making it easy to spot vocals, silences, beats, and transitions. Drag the handles for quick selection, type exact timestamps for frame-perfect precision, or use keyboard shortcuts (arrow keys for fine-tuning, Shift+arrows for larger jumps). If your trimmed clip is too quiet, boost it with our Volume Booster.
Best For
TikTok and Instagram creators cutting clips for Reels and Shorts. Podcasters trimming silence and isolating segments. Musicians extracting loops and samples. Students clipping lecture highlights. DJs preparing transitions. Anyone making a custom ringtone. After trimming, boost the volume if your clip is too quiet.
Frequently Asked Questions
Can I trim audio without losing quality?
Yes. Trimming extracts the exact audio samples from the selected region — no re-encoding happens during the cut. The final MP3 is encoded fresh at 320 kbps, the highest quality MP3 encoding.
How precise is the trimming?
The tool works at sample-level accuracy (1/44,100th of a second for standard audio). You can fine-tune the selection using keyboard arrow keys or type exact timestamps in the input fields.
Can I trim multiple sections from one file?
Currently, you can select and export one continuous region per trim. For multiple sections, trim each one separately and download each clip.
Does it work with long files?
Yes, files up to 50 MB and 20 minutes are supported. The waveform loads fully, and you can visually navigate to any section for precise trimming.
Can I make a ringtone from a song?
Absolutely. Upload the song, select a 20-30 second region of your favorite part, and export as MP3. Most phones accept MP3 files as custom ringtones.
What audio formats are supported?
MP3, WAV, OGG, FLAC, M4A, AAC, and WebM. The output is always a 320 kbps MP3 file.
Is my audio uploaded to a server?
No. All processing happens locally in your browser using the Web Audio API. Your files never leave your device.
How good is the audio processing quality?
We use the same techniques found in professional audio software: convolution reverb with real impulse responses, phase vocoder time-stretching, HRTF-based spatial audio, EBU R128 peak limiting, and LUFS loudness normalization. What you hear in the preview is exactly what you get in the export — we guarantee preview/export parity across every tool.
