Chorus, phaser, and flanger effects are based on small delays measured in milliseconds. A chorus effect occurs when sounds with nearly identical pitch and timbre are layered, creating a sense of plural singing. It is commonly used on vocals, strings, and other instruments. A phaser filters a signal by modulating a series of peaks and troughs in the frequency spectrum, creating notches that vary over time. It was first used with guitar and is now used on many instruments and sounds. Both effects make use of low-frequency oscillations and delay parameters to shape their sound.

2. Introduction
 Chorus, phaser and flanger effects are effects that actually are based on
the delay. Of course, this delay effect is really small and counted with few
milliseconds. With this small delay we can hear some differences on the
timber or pitch of our main sound.
 This effects have some commons uses which I am going to talk about.

3. Chorus
 A chorus effect occurs when individual sounds with the same timbre and
nearly (but never exactly) the same pitch are attached and are
perceived as one.
 This effect is generally used in vocals or secondary vocals, to give a new
sense of plural singing in the main vocal or just in the background. It is very
used as well with strings and orchestra intstruments.

4. These are the parameters of the
chorus effect in FL Studio. The
main parameters are the Delay
in milliseconds and the LFO
amount and wave parameters.
LFO is Low-Frequency Oscillations
which is effect of the modulation
created under 20hz. These
modulations are important to
configure the chorus as we
want.

5. Phaser
 A phaser is an electronic sound processor used to filter a signal by
creating a series of peaks and troughs in the frequency spectrum.
The position of the peaks and troughs is typically modulated so that
they vary over time.
 This effect appeared first with the guitar. Then with electronic music
emerging, phasers start to be used in any instruments or sound or
even vocals.

6.  These are the parameters of a
phaser effect in FL Studio. The
main ones are the sweep
frequency and the minimum
and maximum depth, which
allows us to decide how big
we want out notches.

7.  Before a started this course, I didn’t expect this effects to be related with
the idea of delay. Now I understand way better how it works. Hope you
also understood my lesson and that you liked it. Thank you very much.
