Lesson 5: Delay

Assignment from lesson 5, Intro to music production courser.org and Berklee College of music.

Transcript

1. BERKLEE'S INTRODUCTION TO MUSIC PRODUCTION AT COURSERA.ORG Hi, and welcome! my name is John Tinjaca, I’m from Bogota, Colombia. I’m taking the Berklee's Introduction To Music Production at Coursera.org This lesson is for week 5, part of the assignment; I will be explaining: Delay spectrum, comb filtering and types of delay
2. DELAY EFFECT
3. A delay is an effect where the in coming audio is being repeated over time (steps or milliseconds). In most cases the effect is combined with sliding down the volume while the effect progresses over time (feedback amount). http://media.reasonexperts.com/uploads/delay-explained.jpg
4. In popular and electronic music, electric guitarists use delay to produce densely overlaid textures of notes with rhythms complementary to the music. Vocalists and instrumentalists use it to add a dense or ethereal quality to their singing or playing. Extremely long delays of 10 seconds or more are often used to create loops of a whole musical phrase. http://www.indyweek.com/imager/skaggs-artistic-flight-encounters-further-delay/b/original/1278261/26fa/unknown.jpg
5. COMB FILTERING
6. In signal processing, a comb filter adds a delayed version of a signal to itself, causing constructive and destructive interference. The frequency response of a comb filter consists of a series of regularly spaced spikes, giving the appearance of a comb. (Wikipedia) http://audiogeekzine.com/wp-content/uploads/combfiltering1.jpg
7. You can run into comb filtering whenever there is some kind of reflective surface near a microphone or your ears. https://soundcloud.com/theaudiogeek/book http://upload.wikimedia.org/wikipedia/commons/9/99/Comb_filter_response_ff_pos.svg
8. SLAPBACK DELAY
9. A short single-repeat echo effect often heard in ’50s pop and rockabilly styles. Slapback delay is often used on electric guitar, but can also be applied to drums, vocals, and more. Delay times are usually short, in the range of 40-120 milliseconds, with the delay effect mixed up quite loud against the dry signal.

10. LONG DELAYS
11. Extremely long delays of 10 seconds or more are often used to create loops of a whole musical phrase. Robert Fripp used two Revox reel to reel tape recorders to achieve very long delay times for solo guitar performance. He dubbed this technology "Frippertronics", and used it in a number of recordings. http://proyectoidis.org/wp-content/uploads/2013/10/fripp-2.jpg https://www.youtube.com/watch?v=Wk4Tq-JyP0w

13. I hope this will help to introduce to the concept of delay and get you interested in the creative uses of it. Please feel free to let me know what do you think about this presentation, and if there is anything I could do to make it better, just let some comments, I will appreciate! Cheers!! THANK YOU!
