Frequently asked questions
What is reverse reverb and how do I create it?+
Reverse reverb is created by: (1) reversing the dry audio, (2) applying reverb to the reversed version, (3) reversing the reverbed result. The output is a swell of reverb that builds up to the transient rather than trailing after it. Use this tool for steps 1 and 3, and apply reverb in your DAW for step 2.
Does reversing audio reduce quality?+
No — audio reversal is a lossless operation for uncompressed formats (WAV, FLAC). For MP3, the reversal requires decoding all frames, reversing the sample order, and re-encoding. The re-encode introduces minimal quality loss at the same bitrate.
Can reversed audio be used for subliminal messaging?+
So-called backmasking (hiding messages in reversed speech) has no scientifically demonstrated subliminal effect. Reversed audio is simply a creative effect. Any perceived 'messages' in reversed speech are a product of auditory pareidolia — the human brain finding patterns in noise.
