EFFECTS

OVERVIEW

SAMPLE DELAY

Sample Delay is a precision utility plug-in that delays an audio signal by a specific number of samples or milliseconds rather than musical note values. While a standard echo might delay a sound by a 1/4 note, Sample Delay can delay a sound by a single sample (the smallest unit of digital audio). This is primarily used to align microphones that are at different distances from a source or to create the "Haas Effect" for stereo widening.

Key Features

Independent L/R Delay: Allows you to delay the left and right channels by different amounts.
Sample/Millisecond Toggle: Switch between delaying by samples (for phase alignment) or milliseconds (for stereo effects).
Link Button: Links the left and right sliders so they move together.
Precision Control: Offers much finer timing control than any other delay plug-in in Logic Pro.

Best Use Cases

Phase Alignment: If you record a guitar with two microphones and one is further away, use Sample Delay on the "closer" mic to align them and prevent a thin, "hollow" sound.
Stereo Widening (Haas Effect): By delaying one side of a mono track by roughly 10–30ms, you can make the sound feel incredibly wide and "stereo" without changing its tone.
Fixing Latency: Manually nudging a track forward or backward in time to compensate for hardware or software lag.

Popular Song Examples

The Beatles – "Yesterday"
AC/DC – "Back In Black"
Van Halen – "Runnin' with the Devil"
Daft Punk – "Get Lucky"

Workflow Tips

The "Hollow" Sound Test: When using Sample Delay to widen a sound, always check your mix in Mono. If the sound disappears or sounds "tinny," your left and right channels are fighting each other (Phase Cancellation).
Samples vs. Milliseconds: Use Samples for fixing microphone issues (like a drum kit). Use Milliseconds (ms) for creative widening effects.
Haas Effect Sweet Spot: For stereo widening, stay between 10ms and 30ms. Anything less than 10ms can cause phase issues; anything more than 35ms will start to sound like a distinct "echo" rather than a wider sound.

FAMOUS USES

(These songs didn’t use Logic’s Sample Delay specifically, but they are strong examples of different reverbs.)

Yesterday

The Beatles – "Yesterday"

Song Duration: 2:05

Timestamp: 0:00

Use: String Double-Tracking – While originally done with tape, the "wide" feeling of the string quartet is a classic example of how a slight time offset between left and right channels creates a massive sense of space.

Back in Black

AC/DC – "Back In Black"

Song Duration: 4:15

Timestamp: 0:00

Use: Multi-Mic Guitar Phase – This track is famous for its punchy guitar tone. Engineers use tools like Sample Delay to ensure multiple microphones on the guitar cabinets are perfectly "in phase," resulting in a thick, powerful sound.

Runnin' With The Devil

Van Halen – "Runnin' with the Devil"

Song Duration: 3:36

Timestamp: 0:00

Use: The Haas Effect – The guitar is panned hard left with a short delay panned hard right. This creates a "pseudo-stereo" effect that makes a single guitar track sound like it’s filling the entire room.

Get Lucky

Daft Punk – "Get Lucky"

Song Duration: 4:08

Timestamp: 0:00

Use: Tight Percussion Alignment – Electronic producers use sample-accurate delay to ensure that layered drum samples (like two different kick drums) hit at the exact same millisecond, preventing "smearing."

VOCABULARY

Sample: The smallest unit of digital audio. At a 44.1kHz sample rate, there are 44,100 samples in one second.
Phase Cancellation: When two identical waveforms are slightly out of sync, causing them to "cancel out" certain frequencies and sound thin.
Haas Effect (Precedence Effect): A psychoacoustic effect where a listener perceives a sound's spatial position based on the first sound that reaches the ear.
Pseudo-Stereo: Creating the illusion of a stereo image from a mono sound source.
Latency: The delay between an audio signal entering a system and emerging from it.
Millisecond (ms): One one-thousandth of a second.
In-Phase: When the "peaks" and "valleys" of two audio waves line up perfectly, resulting in a stronger, louder sound.
