Overdubbing

Overdubs only work when each pass locks to the first in time, tuning and breath.

The problem

When a band cannot play together, or one player covers several parts, the recording is built one pass at a time. The difficulty is making each new pass sit with the timing, tuning and breath of the first; the more passes, the easier they drift apart.

Signal chain

Record a reference part first, usually drums or guitar, carrying the tempo and harmony. Each later pass hears the existing parts through headphones and records to a new track. Cue mix, latency and bleed decide how tight the stack becomes.

Placement and settings

Set tempo and key with the reference part and run a click throughout. Give the existing parts plenty of level in the cue and keep your own instrument slightly lower. Use a buffer of 64 or 128 samples so latency stays under 10 ms, and listen back after every pass.

What to listen for

Sum the reference and the new pass alone and hear whether the attacks land together. A four-pass stack turns timing differences into blurry width rather than weight.

Common misconceptions

• More layers means more weight → without timing, layers only add blur.
• The louder the cue the better → if you cannot hear yourself, pitch and dynamics go first.
• Every pass must be perfect → recording in sections and comping later is normal.
