Tailsync
Read full descriptionHide full description
Make your reverb groove with your music. When your reverb tail matches your track's tempo, the decay fades naturally between beats. This creates a cleaner, more cohesive mix where the reverb enhances the rhythm instead of fighting it. Tailsync calculates pre-delay and decay times instantly based on your BPM and desired room size. Just copy the values into your reverb plugin. FEATURES - Instant tempo-synced calculations - 5 reverb sizes from tight to hall - One-tap copy to clipboard - Beautiful, minimalist interface - Haptic feedback - Works completely offline PRO TIP With iCloud Universal Clipboard enabled, tap any value on your iPhone and paste it directly into your DAW on Mac. No typing required. Perfect for music producers, mix engineers, and sound designers who want their reverb to feel musical, not random. Made with care by AKER.
