Recording Lesson of the Day - Reverb Predelay

I’ve been teaching music production in Hollywood and when the subject inevitably turns to reverb, I make sure to touch on one of my favorite techniques: reverb returns with a prominent pre-delay. Sometimes for extra ear candy, that pre-delay is synced to the tempo of the song. Pioneered to imitate the lag between the initial sound and the subsequent acoustic reflections in real-world environments, this pre-delay temporally separates the initial (dry) sound from its (wet) reverb returns, and can improve clarity, even when a lot of reverb is used. Before trying this yourself, it’s ideal to hear some obvious uses in existing recordings, so I’ve made a playlist of some of my favorite examples (headphones on): https://open.spotify.com/playlist/63U1sNK8ZqlFSVx2QbG9oV

Almost every reverb plugin has its own pre-delay setting, but if you want to do more exciting things with pre-delay, you should set this to zero or as close to zero as it will go, and add a separate delay plugin before the reverb return. NB this only works if you’re using send-and-return style reverb (which is the preferred method of using reverbs and delays the majority of the time). This delay plugin is now your reverb’s pre-delay knob, with the added excitement of controls such as:

  • syncing to the tempo of the song you’re working on (try a 16th note, 8th note, or a dotted 16th!)

  • optional warble (most delay plugins have an LFO controlling the delay time; a subtle bit of this delay time at a speed less than 1Hz will provide a really nice shimmer to your reverb, and helps emulate the inconsistencies of analog tape delays historically used for this purpose)

  • feedback / regeneration of the pre-delay (https://en.wikipedia.org/wiki/Send_tape_echo_echo_delay)

  • tape saturation (if you’re using a delay plugin that models analog tape)
