Frequently Asked Questions

What is audio reversal?

Audio reversal is the process of playing an audio file from end to beginning. This creates unique sound effects often used in music production, sound design, and creative audio projects.

Which audio formats are supported?

We support all major audio formats including MP3, WAV, FLAC, AAC, OGG, M4A, etc. The system automatically detects the format and processes accordingly.

Is there a file size limit?

For optimal performance, we recommend file sizes under 100MB. Processing speed depends on your device performance as all processing is done locally in the browser.

Is my audio data secure?

Absolutely secure! All audio processing is done locally in your browser. We do not upload or store your audio files, ensuring complete privacy and security.

Can it be used on mobile devices?

Yes! Our tool is fully responsive and supports smartphones and tablets. You can upload files, record audio, and download results on any modern mobile browser.

Why is microphone permission needed?

Microphone permission is only used for recording functionality. If you choose to record audio, the browser will request microphone access. You can revoke this permission anytime in your browser settings.
