Did you know that you can find satanic messages embedded in those squeaky-clean pop songs? All you must do is to reverse the audio or add a rewind effect to the sound file. And this is a very straightforward process that can be coupled with a proper audio reverser. However, with many options available in the market, it becomes difficult to take the end call.

If you have been trying to zero in on the perfect audio reverser to play the file backward, then you have come to the right place. There we are going to discuss the best available audio reversers for reversing audio online, on iPhone, and computer.

Part 1: Reverse Audio Online [with Tutorial]

You can benefit a lot from online audio reversers if you need to reverse audio occasionally and don't want to install any third-party software on your computer or iPhones. Let's look at three of the best online destinations this year which can cater to your audio reversal needs.

  3PM AudioTrimmer Audioalter

available in English and German language offers reverse effects such as noise risers or reverse cymbals create 3D/8D audio, boost up bass levels, convert audio.

#1. AudioTrimmer

AudioTrimmer is the most compatible online audio reverser tool in our lists. It can play audios in MP3, WAV, WMA, OGG, M4R, 3GPP, AIF, AMR, FLAC, AAC, M4A formats backward. The drawback is it only allows you to reverse audio file under 10MB and the output file codec has to be MP3. There is no access to customize the audio playback speed, quality, and other personal settings. Worse more? There are plenty of pop-up ads that may lead you to unsafe sites.

#2. 3PM

The maximum file size you can add to 3PM is 20MB and the supported file formats are MP3, OGG, and WAV. It allows you to change the speed of the reversed sound (speed ranges from 0.5x to 2x). Just like AudioTrimmer, one of the biggest loopholes of 3PM online tool is that it has a fully automated process which doesn't allow adjustment. Thus, your potential becomes limited.

#3. Audioalter

Audioalter, according to us, is the number one option when it comes to online audio reversal. Though its reverse feature is similar like AudioTrimmer. Under the audio reverse tab, you upload 20MB (maximum) MP3, WAV, OGG, or FLAC audio file, and then it will do the rest automatically. But, you can then reload the reversed audio to Audioalter for making advanced adjustments. This completely free-of-cost audio reverser software stacks in immense possibilities in terms of audio equalization, conversion, speeding up or slowing down, pitch shifting, bass boost, audio trimming, volume change, removing vocals. Better yet, it enables you to take the above job done in one click. It even lets you create a 3D or 8D sound effect.

  • #3. Logic Pro X

    As one of the most comprehensive DMI in the market, Logic Pro X has a high price tag: $199.99. Honestly speaking, reversing audio with Logic Ro X is like using a hammer to kill a fly. But advanced users, for instance, musician and artist who want to mine a reversed audio for creative inspiration and need to cope with many audio post-editing work, bound to feel delighted with the bevy of editing toolkits and effect plug-ins offered and supported by Logic Pro X.

    Logic Pro X has minimum system requirements of 4GB RAM, OS X 10.8.4 or later and 64-bit Audio Units. It comes with an intuitive interface that is in line with the operating habits of most people. The reversing of the whole audio file is easy like walking in the park. However, it needs many redundant steps if there is a need to reverse some certain parts of the audios.

    #4. REAPER

    REAPER is a one-stop yet still affordable digital audio production software that runs on Windows and OS X. It brings you a flexible and robust toolset to record, edit, process, and mix audios. I have to admit that I've read some tutorials before reversing audio with REAPER. Its interface is too brief for me. Many important options are hidden.

    I have tried 2 methods. 1) Reverse in Item Properties to reverse audio without creating a new copy. 2) Go to item and reverse item as new take. Both work fine. REAPER can export the reserved audio as WAV, AIFF, FLAC, OGG and MP3 sound file. With it, you are free to decide the output quality and other properties. However, you need to have basic knowledge about the terminologies of audio editing to get the desired outcome.
