DeFilter effortlessly restores clarity and balance to your audio by intelligently correcting tonal imbalances and suppressing resonant peaks—even in acoustically challenging recordings. Unlike conventional EQ tools, it can target complex issues like comb filtering and room-induced coloration, while preserving the natural character of your source.

Whether you’re matching recordings to a speech or music profile, or equalizing one clip to mirror another, DeFilter streamlines the process with precision and transparency. Tailor corrections with flexible, frequency-dependent curves, and monitor every tweak in real time with dual spectrum analyzers—all through an intuitive, no-fuss interface designed for speed and control.

DeFilter is ideal for audio that suffers from unnatural tonal imbalances, especially those caused by poor recording environments or inconsistent EQ across takes. Here are some specific types of audio where it really earns its keep:

  • Dialogue recorded in untreated rooms – Think comb filtering, boxiness, or excessive room coloration. DeFilter can smooth out those resonances and bring the voice closer to a studio-quality tone.
  • Archival or field recordings – Old tapes, on-location interviews, or found sound often have spectral issues. DeFilter helps restore clarity without over-processing.
  • Mismatched multi-mic setups – If you're blending lavs, booms, or different mic types and the tonal balance is inconsistent, DeFilter can help align them by learning and applying a reference profile.
  • Music tracks with problematic EQ – For example, a dull acoustic guitar or a harsh upright bass. DeFilter can tame resonances or lift dullness without the guesswork of manual EQ.
  • ADR or VO that doesn’t match production audio – Use DeFilter to match the spectral profile of production sound, making the transition between takes more seamless.
  • Automatic tonal correction based on speech, music, or custom reference profiles
  • Comb filter and resonance removal for cleaner, more natural sound
  • Reference matching to align timbre across recordings or sessions
  • Customizable correction curves for frequency-selective processing
  • Dual real-time spectrum analyzers for clear visual feedback
  • Intelligent preservation of source character, avoiding over-EQ’ing
  • Intuitive, efficient interface designed for fast and focused workflows
