Real-Time Voice Scrambler

Phantom I/O is the one and only REAL-TIME pitch shifter, modulator, and band-inversion scrambler/descrambler app! Featured in Speech Technology Magazine, Digital Pro Sound, and Gizmodo!

Disguise your voice for online games. Create unique musical effects for live or recorded performances. Expand pitch range of voiceover work. Create scary voice effects for Halloween costumes. Disguise your voice from unwanted callers. Conduct private conversations. Descramble radio communications.

Phantom I/O samples audio from the microphone and sends the processed output straight through to the speaker/headphone jack in real-time. It's a perfect solution for live audio effects and interfacing with other equipment and processing gear.

Unlike other gimmicky "toy" audio apps on the market, Phantom I/O is a professional grade app with unmatched features and performance. Shop around and you'll see just what a great value it really is! This app replaces over $200 in specialized audio processing gear.

No flashy graphics. No cutesy cartoon icons. No ads. Just a simple interface designed for pro-grade audio processing.

Advanced DSP algorithms provide high quality audio with minimal processing delay. Supports all common scrambling frequencies.

THIS APP DOES NOT PROCESS AUDIO DURING PHONE CALLS MADE ON THE SAME DEVICE. THIS IS A LIMITATION OF THE ANDROID OPERATING SYSTEM, NOT THE APP. When the app is running, it can only function as an audio processor, so a second phone is required to actually make the call.
