The following review written by one of the Software Informer contributors applies to version 2.5
If someone tells us about listening to recordings with reversed speech on it, probably the first two words that will come to our mind are “Paranormal Activity”. The truth is that Reverse Speech Professional was not designed to create and reproduce these paranormal recordings from the afterworld, but the hidden messages that our subconscious throw in nearly every time we say something.
The theory is that for every sentence we say forwards there is a hidden statement that can only be heard if we play our speech backwards. These statements are usually a complement of what is being said forwards – either a reinforcement of what has been said, or the hidden truth behind our words.

This is the reason why Reverse Speech Professional was created, and the truth is that instead of just being a simple tool that reverses audio files, it is actually one of the most comprehensive, full-featured, and professional-looking audio editors you may find out there. It allows you to do with your audio files everything you would expect from the most sophisticated audio editor, and reversing them is just one tiny fragment of its whole functionality. The amount of data you will find in the screen may be overwhelming at times, but this is only a sign of the scientific approach used to build this application.

You can open any WAV, MP3, AU, RAW, or SND file and save it in any other of the formats supported – so, first of all, it is a sophisticated conversion tool. The audio file is shown in wave form, using clear and strong colors to help you select the desired fragment(s). The selection process is simple and intuitive – your cursor becomes a thin line that will help you accurately slice the wave form in as many sections as you wish. The visualization of the audio file is highly accurate, and this can be tweaked to fit the most demanding preferences. The same is true for playback – you can change the speed of the audio as slightly as 1/100 of normal speed. It also allows you to play loops, make a “U turn”, etc.

The list of functions, filters, effects, and tools would be too long to mention here. Just to give you a rough idea, Reverse Speech Professional allows you to fade in and out any file or fragment, to move portions of audio to anywhere in the same file or a different file, to compress it and expand it (also dynamically), to equalize it (using up to 50 bands!), modulate it, stretch it, add noise reduction, reverb, or shift the pitch, mix and interchange the channels, and so on and so forth.

To sum up, and regardless of the true reason behind the creation of this tool, Reverse Speech Professional can be regarded as one of the most comprehensive, intuitive, and well-designed audio editor you can put your hands on.


  • Fully customizable wave form representation of the audio file.
  • Comprehensive selection of filters, effects, and editing functions.
  • You can easily re-encode your audio files to any of the different codecs supported.


  • None.
