Common Examples
Trim Audio File
Remove silence or unwanted segments from the beginning or end of a podcast or music file.
Convert WAV to MP3
Convert a large WAV file to MP3 format to reduce file size while maintaining good audio quality (192kbps or higher).
Normalize Audio Volume
Balance audio levels to standard broadcast levels, ensuring consistent volume throughout the file.
Adjust Playback Speed
Speed up a podcast to 1.25x or 1.5x for faster listening, or slow down music for practice.
Common Mistakes to Avoid
- Using too low bitrate when converting to MP3, resulting in poor audio quality. Use at least 128kbps, preferably 192kbps or higher.
- Not normalizing audio before trimming, which can result in inconsistent volume levels.
- Extreme speed adjustments (below 0.5x or above 2x) can cause audio artifacts and poor quality.
- Forgetting to check output format compatibility with your target device or platform.
Frequently Asked Questions
Are my audio files uploaded to a server?
No. All processing happens entirely in your browser using FFmpeg.wasm. Your audio files never leave your device.
What audio formats are supported?
The tool supports MP3, WAV, OGG, AAC, and FLAC. You can convert between these formats.
What bitrate should I use for MP3 conversion?
For music, use 192kbps or 320kbps. For speech/podcasts, 128kbps is usually sufficient. Higher bitrates mean better quality but larger files.
Can I edit multiple audio files at once?
Currently, the tool processes one file at a time. Process each file individually for best results.
How does audio normalization work?
Normalization automatically adjusts the volume to standard broadcast levels, ensuring consistent loudness throughout the file.
What's the maximum file size?
The tool can handle files up to several hundred megabytes, but very large files may take longer to process. For best performance, use files under 100MB.
