VideoAudioFX

VideoAudioFX allows you to remix the audio in your videos without touching the video itself. Import a video, run its audio through a professional effect chain (EQ, reverb, compression, limiting, and fades) and export with the video passed through completely untouched. No re-encoding, no quality loss, no waiting on a full video export just to remix the sound. Effects • 5-band graphic EQ with an interactive frequency-response graph • Algorithmic hall reverb, from a simple decay/mix control to full expert-level tuning • Compression and limiting with real-time gain-reduction metering • Adjustable fade in/out Built for iteration Every effect updates in real time against a live preview, synced to your video, so you can hear exactly what you're getting before you commit to anything. A high-resolution waveform display makes it easy to scrub to any moment. Save what works Save your effect settings as named presets and reapply them instantly to your next video. No need to rebuild your sound from scratch every time. Fast, faithful import Import directly from Photos or Files. Direct Photos import pulls your video's original file, avoiding the quality loss and slowdown of a standard "compatible" re-export — especially noticeable on long or HDR footage. Untouched video, every time Export re-encodes only the audio track. The video itself is passed through bit-for-bit, so there's no re-compression artifacts and no wasted time on unnecessary video processing. One-time purchase No subscription. Preview every effect for free, and unlock unlimited exports with a single one-time purchase.
