About
A browser-based audio trimmer that lets you cut unwanted parts from audio files. You can visually specify start and end points on the waveform and save only the selected range.
Perfect for creating ringtones, editing podcasts, or trimming voice memos. Files are never sent to a server and are processed securely on your device.
How to use
Select Audio File
Select an audio file such as MP3, WAV, or OGG. The file is processed entirely within your browser.
Specify Range
Drag the handles on the waveform to set the trim range. You can verify it with preview playback.
Trim and Save
Save the selected range in WAV format. Exported quickly without quality loss.
Glossary
- Waveform
- A visual representation of an audio signal showing amplitude over time. It allows you to intuitively identify silent parts or specific sounds for precise trimming.
- Sample Rate
- The number of times per second an analog audio signal is sampled to digital data, measured in Hz. CD quality is typically 44,100Hz. This tool preserves the original rate when possible.
- Bit Depth
- Determines the dynamic range of the audio. A 16-bit depth offers 65,536 levels of precision, providing high-fidelity sound representation.
- Trimming
- The process of removing unwanted portions from the beginning or end of an audio file. Common for making ringtones or removing silence from podcasts.
- WAV Format
- An uncompressed audio format that preserves exact original sound quality (lossless) but results in larger file sizes. It is a standard in professional audio production.
- MP3 Format
- A widely used compressed format that reduces file size by removing inaudible frequencies. This tool supports MP3 encoding at a standard 128kbps.
- AudioBuffer
- An object in the Web Audio API used to hold short audio assets in memory, enabling fast waveform rendering and editing within the browser.
- Channel
- The number of audio pathways. Mono (1 channel) plays identical sound from all speakers, while Stereo (2 channels) creates a spatial effect.
FAQ
- Q.What audio formats can I import?
- The tool supports almost all major formats that your browser can decode, including MP3, WAV, OGG, AAC, and FLAC.
- Q.Will my audio files be uploaded to a server?
- No. All processing is done entirely locally within your browser. Your files are never uploaded or sent to any external server, ensuring complete privacy.
- Q.What output formats are supported for saving?
- You can export your trimmed audio as either an uncompressed high-quality WAV file or a compressed MP3 file to save storage space.
- Q.Can I process very long audio files?
- Yes, but it depends on your device's available memory. Audio up to a few tens of minutes usually works fine, but files several hours long may fail to load.
- Q.Can I preview only the selected portion before saving?
- Yes. Click the 'Play Selection Only' button to listen to the exact segment you have chosen to keep.
- Q.Does this tool work on smartphones and tablets?
- Absolutely. The interface is fully responsive, allowing you to intuitively drag the start and end handles using touch controls.
- Q.Will there be any loss in audio quality?
- Exporting as WAV maintains the original sample rate and channels with no quality loss. Exporting as MP3 applies standard compression at 128kbps.
- Q.Can I specify the exact time for trimming?
- Yes. Besides dragging handles on the waveform, you can manually input the exact start and end times down to the millisecond in the text boxes.
