What software do you use?

To create subliminal effect in audio files?

Me and a friend are doing a project on subliminal messaging, and she wants to have an experiment where I put a message into a normal mp3 song, and have her listen to it, to put a trigger in her mind.

This would really help us.

Thank you in advance.

I use Zerius Vocoder to mask the suggestions as part of the sound (I generally use surf, rain, or other nature sounds) and Audacity for the basic editing/combining of tracks. Both programs are free and Linux-compatible (though Zerius Vocoder requires Wine to run on Linux)
