자주 묻는 질문
Quick answers.
›Will the audio pitch change if I speed it up?
No. The tool uses a time-stretching algorithm that preserves the original pitch while only altering the playback duration.
›Which audio formats are supported?
Most standard formats compatible with your browser are supported, including `MP3`, `WAV`, `OGG`, and `AAC`.
›Does this tool upload my audio files?
No. All audio processing is handled by your browser's local engine. Your files stay on your device and are never sent to our infrastructure.
›Can I save the modified audio file?
Yes. After adjusting the playback speed to your preference, you can export and download the resulting audio file directly from the interface.
