Motion FX

Motion FX creates dynamic spatial audio effects that simulate realistic animal movement. The stereo output works universally - stereo systems get full spatial positioning for maximum realism, while mono systems automatically mix the channels to create beneficial frequency and amplitude modulation. Perfect for distress calls, predator vocalizations, and territorial disputes.
  • Motion FX always outputs stereo files for optimal positioning effects on dual-speaker systems.
  • Mono Compatibility: Files automatically mix down on single-speaker systems while retaining beneficial modulation effects.
  • Pattern Selection: Choose from Random (10s intervals), Ping-Pong (5s cycle), or Circular (6s cycle) motion patterns.
  • Works with all caller types: FoxPro, Lucky Duck, Icotech, FREQ, custom builds, Bluetooth speakers, and phone playback.

⚠ Motion FX is applied during processing — you won't hear it in live preview. Process and download to experience the full effect.

Ultrasonic Enhancement

FREQAI adds a high frequency ultrasonic sound layer in the 25–60 kHz range, beyond the average human hearing limit of 20 kHz. While most wildlife callers will still play the standard audible frequencies, ultrasonic sounds require specialized amplifiers and speakers for full effect.
  • High Frequency tracks are 96 kHz WAV files with an ultrasonic layer above the audible call.
  • 16-bit uses the Burnham Brothers recipe, tested working on Burnham Brothers callers. 24-bit and 32-bit use the standard layer and need a caller that plays 24-bit or 32-bit files.
  • Hardware Limitations: callers without ultrasonic-capable amplifiers and speakers play the audible call only.

⚠ FreqAI ultrasonic processing is applied during export only — it cannot be heard in live preview. Process and download to hear this layer.

16-bit, 96 kHz WAV with a strong ultrasonic layer at 25 to 47 kHz. Tested working on Burnham Brothers callers. Burnham Brothers does not support 24-bit.

Choose Your Audio Output Format

Select the file format that works best with your calling setup:

⚠ Some devices may not support WAV files, high-resolution audio, or ultrasonic playback.

⚠ Compatibility varies by caller and firmware - if unsure, start with MP3, or 16-bit WAV for ultrasonic.

By processing, you confirm you own or have the rights to any sounds you upload.
