How to record music
Step 1: The Recording
Process
In the earliest days of the music recording…
The process was much simpler than it is today. Entire
performances were recorded in single takes, sometimes with just 1 or 2 mics.
Today though, we use a more sophisticated process known as multitrack
recording…
Where each instrument is recorded separately and combined
later in a “mix”.
This offers two BIG advantages:
1-It allows engineers to mould and shape the sound of each
instrument independently of the others.
2-It allows each instrument in a song to be recorded one at a
time.
With this new method, it meant that one man could now do
alone, what used to require an entire team of engineers and musicians.
While the actual steps in the process vary from engineer to
engineer…
Here’s a general guideline of how it works:
1. Create a Track to Follow
The first step is creating some kind of guide for the other
instruments to follow along with.
Most people use a simple click/metronome to set a
tempo. But since not all musicians can
follow clicks, you could also use a pre-recorded drum loop instead.
And since not all songs have steady tempos, a third method
is to create a scratch track…
Where an instrument or group of instruments are recorded as
the guide, then “over-dubbed” one at a time, until the original can be deleted
or “scratched“.
2. Record the Rhythm Section
As any musician knows, the rhythm section is the foundation
of any song. When bands play together,
everyone follows the drums/bass.
It makes sense then, that these be the first instruments you
normally record.
In songs that lack drums/bass, another rhythmic instrument
(such as acoustic guitar), can be used instead.
3. Record the Harmonies
Once you’ve built a good foundation, next it’s time to add
to it by creating a chord structure.
Depending on the song, that could mean adding rhythm guitar,
piano, synths, horns, etc.
With a basic chord progressions now in place, next it’s time
to…
4. Record the Melodies
Since most songs use a combination of instruments to form
the melody…
It makes sense that whichever ones are most dominant
(usually lead vocals/lead guitar) be the ones you record first.
Then afterwards, you can fill in the gaps with all the
supporting melodies.
After that, all that’s left is…
5. Add Colour
To put the finishing touches on your song, you add all those
little nuances that add colour and flare to the main tracks.
Common examples might include:
background vocals
percussion fills
piano fills
sampled sound effects
Once you’re happy with everything, you’re ready for the next
phase…
Step 2: The Editing Process
audio editing explained
Now that you’ve finished recording your tracks, it’s time to
clean them up. Because no matter how careful you were in the last step…
There will always be SOME mistakes that can and should be
fixed…
With the amazing editing tools now available in the
DAW’s (Digital Audio Workstation) of
today.
Typically, editing is made up of 5 common tasks:
Arrangement
Comping
Noise Reduction
Time Editing
Pitch Editing
With arrangement, you take an overall look at everything
you’ve done so far, to evaluate what works, and what doesn’t.
For example, you could:
delete entire tracks that don’t add value
cut out sections of
tracks that clutter the mix
move a section to a new part of the song
delete entire sections of the song altogether
With comping, you compare the duplicate takes of each track,
and select the best one. If you like,
you can even select best phrases from each take and combine them all into one
“frankenstein-take”.
With noise reduction, you cut all sounds before, after, and
in-between each section of audio where the instrument is playing.
This means removing:
background voices
amp hissing
footsteps
chair squeaks
breaths
or just dead air
To reduce noise further, you can add a high-pass
filter beneath the lower frequency range of non-bass instruments, to remove
rumbling sounds.
With time editing, you can fix off-beat notes, using
one of two methods:
T
here’s the “cut and paste” method, which works well on
percussive instruments.
There’s the “time-stretching“method, which works well on
almost all instruments.
With pitch editing, you can shift any sour note back
on-pitch, using Auto-Tune or any similar software.
Normally it’s used on vocals, but it also works well on most
melodic instruments.
So that about covers the Editing Process. Now on to the next phase…
Step 3: The Mixing Process
audio mixing explained
Once the tracks are arranged exactly as you like…
The next goal is to make them blend as one cohesive
unit…though the process of “mixing“.
While mixing is an art form in itself, and can be done in
many ways…
There are certain fundamental tasks that everyone does…
Common examples include:
Balancing Faders – which is done so that no
instrument sounds too loud or soft in relation to the others.
Panning – which gives each instrument it’s own space
in the stereo-image, much like each musician has his own space on-stage.
Equalization – which crafts a unique space in the
frequency spectrum for each instrument, so that no two sounds compete for the
same band of frequencies.
Compression – which levels out the dynamic range of
an instrument so each note is heard clearly, and the mix sounds louder as a
whole.
Reverb – which creates 3-dimensional space for the
mix, adding a sense of depth, and unifying the instruments under one
room-sound.
Automation – which allows you to change settings at
different points in the song, to give your mix a sense of movement.
Once you’ve used these tools to craft your mix, and it
sounds great…
It’s finally time for the last step…
Step 4: The Mastering Process
audio mastering explained
Before your song is ready to be mastered…
All tracks must be re-recorded down to a single stereo file…
Or “bounced“, as it’s commonly known.
Once that’s done, various mastering techniques are used to
put the finishing touches on your song…
So it sounds even better.
Common techniques include:
Maximizing Loudness – through further compression and
limiting, so the average signal level over time is as high as possible, without
sacrificing too much dynamics.
Balancing Frequencies – through further EQ, and a
process known as multi-band compression, which can compress individual frequency
bands separately from the rest of the spectrum.
Stereo Widening – with a special plug-in designed to
add an additional sense of “width” to the higher frequencies in your mix.
Once everything sounds perfect, the track is converted to
its appropriate sample rate/bit depth.
For example, CD audio is 44.1 kHz/16 Bits.
DIY or Outsource?
To put it simply, mastering is hard. And if you don’t know what you’re doing, you
can easily make things worse, rather than better.
That’s why it’s standard practice for mix engineers
outsource the work to a “mastering engineer“, rather than doing it themselves.
However…Good mastering engineers cost good money, which not everyone
has, or cares to spend.
So the question is…
Is mastering always necessary? Decades ago, when all studio recordings were intended for
sale, everything was mastered.
Today however…now that many amateur recordings are done
“just-because“…
Home studios will often do their own mastering, or skip it
entirely. And that’s fine.
If all you do is share your music with family and friends,
then who cares?
However…
If you want to record music professionally, or…
If you simply want your work to sound as good as it can… then go for Mastering!
