Sample Rate & Bit Depth Guide
Higher sample rates and bit depths provide better quality but create larger files. Choose based on your needs.
| Use Case | Sample Rate | Bit Depth | File Size |
|---|---|---|---|
| Music production | 48 kHz | 24-bit | Large |
| General use | 44.1 kHz | 16-bit | Medium |
| Voice recording | 22.05 kHz | 16-bit | Small |
Recommended Settings by Use Case
| Scenario | Sample Rate | Bit Depth | Channels | Tip |
|---|---|---|---|---|
| Music production | 48 kHz | 24-bit | Stereo | Use for professional editing |
| General archive | 44.1 kHz | 16-bit | Stereo | Standard CD quality |
| Voice notes | 22.05 kHz | 16-bit | Mono | Smaller files for speech |
| High-res audio | 96 kHz | 24-bit | Stereo | Maximum quality |
Trim, Fade & Normalize
- Trim: Export only a segment using start/end times.
- Fade in/out: Smooth the clip edges to avoid clicks.
- Normalization: Level overall loudness to prevent sudden volume jumps across files.
Privacy & Security

WAV vs MP3 vs FLAC
| Format | Quality | File Size | Compatibility | Notes |
|---|---|---|---|---|
| WAV | Perfect | Very Large | Excellent | Uncompressed, universal |
| MP3 | Good | Small | Excellent | Lossy compression |
| FLAC | Perfect | Medium | Good | Lossless compression |
Need maximum compatibility? Choose WAV. Need smaller files? Consider FLAC.
Browser Support & Notes
- Works on current Chrome, Firefox, Safari, and Edge.
- WAV files will be much larger than MP3 originals.
- Keep this tab active; some mobile browsers throttle background tabs.
Troubleshooting
- No sound in result: Source may contain unsupported audio codec; try re-recording or converting the source first.
- Audio out of sync: Trim on key points and keep the original sample rate.
- Distortion or clipping: Disable normalization or reduce gain.
- File too large: Lower sample rate, switch to mono, or shorten duration.
What is MP3?
MP3 (MPEG-1/2 Layer III) is a lossy audio format offering excellent compatibility across devices and platforms.
What is WAV?
WAV (Waveform Audio File Format) is an uncompressed audio format that preserves the original sound quality but creates very large files.
Use Cases: When to Convert MP3 to WAV
- Audio editing: Use WAV files in professional audio software.
- Archiving: Create uncompressed copies for long-term storage.
- Compatibility: Ensure files work on older devices that don't support MP3.
- Yes. It's completely free with no registration or watermark.
- No. You cannot recover quality lost during MP3 compression. WAV will preserve the current quality.
- WAV files are typically 10x larger than MP3 files due to no compression.
- 44.1 kHz is standard for music. Use 48 kHz for video production, 96 kHz for high-res audio.
- Yes. Use start/end time to export a specific segment.
- 24-bit provides more dynamic range and is preferred for professional audio work.
- WAV files are uncompressed. Higher sample rates and bit depths increase file size significantly.
- Some MP3 metadata may be lost. You can add tags later in your player/editor.
- Yes. WAV files are the standard for professional audio editing and production.
- Up to 100 MB per file.
For archival purposes, consider FLAC for lossless compression with smaller files. Choose WAV for maximum compatibility.
