Questions fréquentes

Quick answers.

Is my audio file uploaded to your servers?

No. The reversal process is performed entirely within your browser using your device's local memory.

Which audio formats are supported?

The tool supports common formats including `MP3`, `WAV`, `OGG`, and `M4A` depending on your browser's native codec support.

Does reversing audio affect the sound quality?

No. The tool simply reorders the existing digital samples. Unless you choose to export in a lossy format like low-bitrate MP3, the signal integrity remains identical to the source.

Is there a file size limit?

The limit is determined by your browser's available RAM. Most standard songs and voice recordings will process instantly, but very long recordings may require more system memory.
