1. Hi again, my name is Guillermo Delgado
from Mexico City and i am excited
because is week 5 of this great course
and all things are going really well with
my learning to improve my production
works. Again please excuse me about
my bad english but i am trying to do the
best in my assignments to get
everybody understand what i am trying
to teach. Until next week,
THANKS TO READ!

3. First lets think that a
Delay is a sound effect
that consists in
multiplication and delay
of an audio signal. The
processed signal is mixed
with the original.
4. Knowing what a Delay is
then we can talk about a
variation of this
processors, the
modulators, in other words
The signals are repeated
with a slight delay and
subject to a small frequency
variation.
5. Modulation effects are used
to add movement and depth
to the sound. Normally they
act by slowing the incoming
signal a few milliseconds and
using an LFO to modulate
the delayed signal. LFO can
also be used to modulate the
delay time at some effects.
6.
7. A low frequency oscillator (LFO)
is very similar to the sound
generating oscillators found on
synthesizers, but the frequencies
generated by an LFO are so low
that they can be heard. Therefore
only used for modulation
purposes. LFO parameters are
speed (or frequency) and depth,
also called intensity control.
8. You can also control the ratio of
the signal affected (wet) and the
original signal (dry). Some
modulation effects include
feedback parameters that add
some of the output of the effect
back to its input.
Various modulation effects are
related to the pitch.
9.
10. This parameter adjusts the delay we want to be
repeated by duration, ie, how often will repeat the
signal.
There is an equation to calculate the delay time
(delay):
Multiplying the result by 1000, we get the value in
milliseconds. (1 sec = 1000 ms).
Alternatively you can use modern tools for
computing repetitions in your phone, tablet or
computer.
11. Practical example:
How many milliseconds (ms) should I have
to adjust the repeats of a mono delay for
an echo to sound just after a measure
beat, if the meter is 4/4 and the song goes
to 118 bpm?
Apply the formula:
=
In other words a beat equals 0.508 secs?
Or what is the same 0.508 x 1000 = 508 ms
12.
13. What I understand
about feedback is the
number of times an
original sound signal
is repeated, we can set
any value between one
and infinity.
14. In other words the signal output of
the delay is readmitted to the same
input to be processed and can be
repeated again and again and again.
The amount of feedback is controlled
by the user and what this means is
that the signal processor will enter,
and then will be delayed by the
amplifier while the entry will be
reentered in the amount of delay that
is required to be processed again.
15.
16. In my opinion Dry/Wet Mix
Parameter is the amount of
delayed sound that is mixed
with the original. You can set
parameter to Dry if no effect is
required or eventually rise the
knob to increase the amount of
effect until get total wet.
18. It is a typical effect used on
electric guitars. Is achieved by
performing a combination of
delay and LFO. That delay values
may vary between 1 and 15 ms
and low frequency between 0.03
and 1 Hz. To get the effect, part of
the low frequency signal is input
to the delay circuit adding to the
direct signal.
19. Operation is based on a slight
delay constantly alternating the
modulation produced by the
LFO, getting a phase change of
the processed signal with the
original. Requires both output
levels or mixing original and
processed, are similar and greater
expression is achieved the higher
the frequency spectrum treaty.
21. The Chorus effect delays the original
signal. The delay time is modulated
with an LFO. Delayed and modulated
signal is mixed with the original
signal, dry.
You can use the Chorus effect to
enrich the incoming signal and create
the impression that they are playing
various instruments and there are
several voices singing in unison.
22. The slight variations in the time
delay generated by the LFO
simulate the subtle pitch and
timing differences you hear when
several musicians and vocalists
perform together. The use of
chorus also adds fullness or
richness to the signal, and can
add movement to low or
sustained sounds.
23. Again thanks for read my
presentation and hope to
be useful and clear with
my terms.
Until next week have a
good recording.
