How can I make an effect like Infinite's voice from Sonic Forces?

A Digital Audio Workstation (DAW): Audacity (free), FL Studio, or Ableton Live are the most popular choices.

  1. Record neutral tone.
  2. Pitch down -6 semitones.
  3. Bitcrush to 5 bits.
  4. Stutter the "c-c-corrupt" manually.
  5. Duplicate for metal ring; add bandpass + distortion.
  6. Reverse reverb on "file."
  7. Layer whisper (right ear) saying the same line.
  8. Add corruption noise after "file" – a descending glitch sweep.
  9. Export as 96kbps MP3 (low bitrate adds extra real-world fuzz – perfect for Fatal Error).

To replicate this effect safely in Audacity (Free Software):
