- Upload the audio file
- Reverse and preview the audio
- Download the reversed audio
Upload Your Audio File
Upload adds an audio file to the reversal queue. The tool accepts MP3, WAV, M4A, AAC, FLAC, and OGG formats up to 50 MB per file. File selection happens through a drag and drop area or a file picker button. Upload starts processing automatically once the file finishes loading.
Reverse and Preview the Audio
Reverse and preview generates the reversed waveform and plays it before download. The tool builds the reversed file immediately after upload. Playback controls include play, pause, and a progress bar. A toggle switch compares the original and reversed versions in the same player.
Download the Reversed Audio
Download saves the reversed audio file to the local device. The output file keeps the original format and bitrate. Download starts with a single click after preview. The server removes the uploaded file within 1 hour of processing.
Which Audio Formats Can You Reverse?
The tool reverses 6 audio formats: MP3, WAV, M4A, AAC, FLAC, and OGG. Each format follows the same 3-step method: upload, reverse, download. The table below defines the supported formats, their compression type, and their common use case.
Format | Compression | Common Use |
MP3 | Lossy | Music, podcasts |
WAV | Lossless | Studio recording |
M4A | Lossy | Apple devices |
AAC | Lossy | Streaming audio |
FLAC | Lossless | Archival audio |
OGG | Lossy | Web audio, games |
Reverse MP3 Audio
MP3 reversal flips the compressed waveform without changing the file format. The output keeps the original bitrate, ranging between 128 kbps and 320 kbps. MP3 is a lossy format, so reversal does not add quality loss beyond the original encoding.
Reverse WAV Audio
WAV reversal processes uncompressed audio at full quality. The output preserves sample rate and bit depth, since WAV is a lossless format. Standard WAV files use a 44.1 kHz sample rate and 16-bit depth.
Reverse M4A, AAC, OGG, and FLAC Files
M4A, AAC, OGG, and FLAC files reverse through the same processing engine as MP3 and WAV. M4A and AAC files keep Apple device compatibility after reversal. FLAC files retain lossless compression. OGG files keep Vorbis or Opus encoding after processing.
