Does this tool reverse my audio file directly?

No. This tool generates the FFmpeg command you need. You run that command locally in your terminal — your file never leaves your computer.

Do I need FFmpeg installed?

Yes. FFmpeg must be installed on your system. On macOS use "brew install ffmpeg", on Ubuntu/Debian use "sudo apt install ffmpeg", on Windows download a build from ffmpeg.org.

What does the areverse filter do?

The areverse filter buffers the entire decoded audio stream in memory and then outputs it in reverse order. The result is bit-accurate playback of the original file played backwards.

Why does FFmpeg need to buffer the whole file?

Reversing is not a streaming operation — you must know the end before you can output the start. FFmpeg reads the full file into memory, reverses it, then writes the output. Very large files may require significant RAM.

Will the output quality match the input?

For WAV and FLAC (lossless formats) quality is identical. For MP3 and AAC there is a small re-encoding step, so using a higher bitrate setting in the command preserves more quality.

Can I reverse a file with multiple audio channels?

Yes. The areverse filter processes all channels simultaneously, so stereo, 5.1, and other multi-channel layouts are reversed correctly.
