Pro Mixing Tip: Stereo Ping-Pong & Haas Delay

For a wide ping-pong stereo delay at 120 BPM: Set Left channel to 1/8 Note (250.0 ms) and Right channel to 1/8 Dotted (375.0 ms). This avoids phase cancellation in mono while delivering sweeping spatial width across headphones.

Tempo-Synced Delay in Modern Mixing

Un-synced delay times can create sonic clutter that fights against a song's rhythmic groove. Syncing delays to musical subdivisions ensures echoes bounce in harmony with the drum groove.

A dotted-eighth delay (0.75x quarter note) or a 1/4 note delay with subtle high-cut filtering creates lush, non-clashing vocal depth.
