This walkthrough segment covers how Ableton Live's Echo device handles reverb and stereo width, two controls that shape the spatial character of a delay effect. The key variable is where the reverb sits in the signal flow: post-delay adds reverb after the echo repeats, pre-delay reverbs the signal before it enters the delay, and placing it inside the feedback loop means the reverb accumulates with each repeat, building into something much denser over time.
Decay length and reverb amount are both adjustable, giving you control over how much space the effect adds. Stereo width can be dialed from wide to fully mono, which matters when you need a delay to sit in a specific part of the mix without spreading across the full field.
