sound ideas
Reverse echo:
As I was reading about Syd Barrett and is experimentation of echoes I discovered a sound concept that I never even knew about, reverse echo. Just regular as regular echo involves a sound being repeated reverse echo involves the sound being repeated backwards. Jimmy page of led zeppelin claims to have discovered this concept while working with the yard birds. According to page they were working on recording of ten little Indians and page apparently was disappointed with the result so he decided to experiment with it. He turned the tape over and recorded the echo of the brass on a spare track then spliced the spare track with original track forwards. Page has used the effect on many led zeppelin songs such as “you shook me”
Reverb:
I remember Mrs. Parrish talking about reverb being buzzing sounds that occurs when making certain sounds. At first I thought reverb was just another term for echo but apparently reverb is the persistence of sound after the original sound is removed. As the sound persists on the sound decays and then is gone. Factors such as the walls or the air in a room can affect the rate of decay.
Phaser effect:
Phasing is and audio effect in which a signal is filter by a series of peaks and troughs in the frequency. There usually used at different settings to make varied patterns of peaks and troughs, hence creating a sweep effect. The effect is created when the signal is split into two and one signal is run through an all pass filter which alters the phases of the frequencies. When the altered signal meets with the regular signal the phaser effect is created.
