VoiceSFX is an innovative program designed to let you record sounds - anything from your own voice to a music CD - and then apply special effects like Helium Breath, Slow Monster, Fade, and Echo to create crazy sound effects. And now you can easily export your creations to MP3 and send them to your friends!

Have you ever thought about where some of those sounds you hear on TV or in the movies came from? How do they make that bizarre alien's voice? Professional sound engineers create special voices and sounds by changing and rearranging recorded sound. Their job is to make sounds interesting, and they generally have a whole rack of expensive effects gear to accomplish that purpose. They can make low sounds high, high sounds low, speed things up or slow things down, add an echo that will make you think the sound was recorded at the Grand Canyon, turn sounds backward, and distort sounds beyond recognition. We think it's far too entertaining to be reserved for professionals, and with VoiceSFX, you can play with sound too!

VoiceSFX is that whole rack of expensive effects compressed into one user-friendly and affordable program. Try out the trial version and you'll find that by combining a few of our special effects, you can create some pretty strange variations.


Make your voice sound like a hyperactive space robot. Create an alien symphony by playing your favorite songs backwards. Not only can you use this program on your own voice, you can also capture sound from any source your computer supports (microphone, line-in, CD, etc.) and then distort it into something wildly weird and different. There are possibilities with this program that we never even thought of - check out the testimonial at the bottom of this page!

After you've created the perfect sound, VoiceSFX lets you either save your creation or export it. When you save, a special header is included in the .wav file telling VoiceSFX which effects to use. This way, when you load the file at a later time, the effects you added will still be there, but can be removed if you like. You can also export to the wave format, MP3 format, or even Real Audio format, so you can send your sounds to friends, burn them to a CD, or season your web page with special effects. This program is guaranteed to make you laugh, and it is simple enough for all ages to enjoy.

  • Record from any source your computer supports (microphone, line-in, etc.)
  • Apply effects to your recorded wave files
  • Save as Wave, MP3, and RealAudio formats
  • Save files in VoiceSFX format, which allows you to open the file later and change your effect settings
  • Adjustable recording and playback volumes
  • A wide variety of instant effects: Echo, Chorus, Flange, Fade, Bass & Treble, Robot-Voice, Backwards, Slow Monster, Fast Squeaker, Sweep Up and Down, Helium Breath and Sulphur Breath

VoiceSFX requires a PC running Windows 8, 7, Vista, XP, 2000

"Recently I had a problem with some audio from a survillence video that was recorded at high speed... No mechanical equipment was available for 'slowing down' the audio so we could hear what was being said and it was critical for our investigation. It was reported that the suspect admitted the crime on this tape BUT the original survillence equipment had been destroyed. I tried several packages that were available to me but nothing would just slow the audio down so I went searching the internet and found VoiceSFX... Hopefully, with the help of your software, we will get a conviction on this guy." -- Randy W., Investigator
