よくある質問
Quick answers.
›Will my audio quality decrease?
No. The tool uses high-fidelity resampling and processing to ensure the output matches the original bit depth and sample rate of your file.
›Is my audio file uploaded to your server?
No. All audio manipulation happens within your browser's memory using the Web Audio API. Your data remains private and stays on your device.
›What is the difference between Fade In and Fade Out?
Fade In gradually increases the volume from silence at the start of the clip, while Fade Out decreases the volume to silence at the conclusion.
›What audio formats can I export?
You can export your modified audio as a high-quality WAV file or a compressed MP3, depending on your playback requirements.
