Send tape echo echo delay

Send tape echo echo delay is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Send tape echo echo delay rather than just read about it. In short: Send tape echo echo delay (more commonly known as STEED, alternatively known as single tape echo and echo delay) is a technique used in magnetic tape sound recording to apply a delay effect using tape loops and echo chambers.

Reference excerpt

Send tape echo echo delay (more commonly known as STEED, alternatively known as single tape echo and echo delay) is a technique used in magnetic tape sound recording to apply a delay effect using tape loops and echo chambers. In 2006, while publicising his memoir (Here, There, and Everywhere: My Life Recording the Music of The Beatles), recording engineer Geoff Emerick stated that "God only knows" how the effect worked.

Technique

The technique was developed at EMI/Abbey Road Studios in the late 1950s, by EMI engineer Gwynne Stock. It involved delaying the recorded (dry) signal, sending it into the studio's echo chamber using a tape machine. The dry signal (without delay) was also sent to the chamber via the tape machine's replay head. The resulting sound was picked up by two condenser microphones. These microphones then fed the wet signal back to the recording console. The amount of feedback could be controlled allowing multiple delays to be sent to the reverb chamber, which could lengthen the effect's decay time. An identical technique was used for the production of Anthology 1 in 1995, where speakers were used to play the sound within the echo chamber.

Use One notable example of the use of STEED is on George Harrison's lead vocal on "Everybody's Trying to Be My Baby" (1964). Mark Lewisohn describes the effect as a "vast amount", and likened Harrison's vocal to singing inside a tin can. He notes that some of the musical backing tracks were also affected by the technique due to microphone spill from Harrison's headphones. Other examples of the use of STEED on Beatles recordings include the vocal fermata in "Paperback Writer" (1966), and Paul McCartney's piano on "Birthday" (1968). The effect was also used on "Revolution 9" (1968), and was used in the mixing of tracks for Anthology 1 in 1995.

Worked examples

Example 1 — a first encounter with Send tape echo echo delay

Start with the simplest possible case. Write down what Send tape echo echo delay claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Send tape echo echo delay before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Send tape echo echo delay ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Send tape echo echo delay

In research: Send tape echo echo delay appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Send tape echo echo delay in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Send tape echo echo delay is common in secondary-school and first-year university syllabi. It links to neighbouring topics Audio effects, The Beatles music, so understanding it makes those chapters shorter.
In everyday life: Look for Send tape echo echo delay outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
