Free
sound editor software can be found to suit the needs of any audiobook narrator
wishing to master the sound recording of the talking book. But which free sound
editing software is best for recording a single voice?

Audacity, WavePad, Cubase, Protools
and Ableton Live Sound Editors |
There
is an array of fantastic sound editing software for the audiobook narrator
wishing to master the recording of a vocal. Some boast many features such as
special effects, musical instrument digital interface (MIDI) for processing
data of many different signals at once. You can even change the color code and
appearance of the dashboard from where you are working.
Examples
of such software include Audacity, ProTools, WavePad, Adobe Audition, AVS Audio
Editor, SoundForge, Ableton Live Lite and Steinberg’s Cubase.
Free Sound Editing Upload
This
all sounds well and good, but when choosing the best recording software for
vocal narration, there are a few things to bear in mind:
The
sole demand of the software is to process the sound of a voice. Unless you
belong to a band or want to create special sound effects for a movie clip, the
additional features are likely to be unused. Furthermore, the sound files of an
audiobook are often required to be in mono, not stereo. This means a single
track of recording will be the only requirement for upload onto a talking book
platform. When it comes to audio software, I prefer the simple ones that are
easy to use and are also free. In this regard, Audacity is highly recommended.
When
it comes to mastering audio, all the voice artist needs are:
A
cut and paste facility that enables the deleting of outtakes, increasing pauses
and shifting the pace of the narration where required.
Equalizing
Sound Engineering
A
good equalizer tool that enables the manipulation of frequencies between 10Hz
to 20,000Hz (20 KHz). And even at this wide range, the ear can barely perceive
the extremes. The lower frequencies represent the base; the higher frequencies
represent the trebles. Manipulating these frequencies can add punch and clarity
to the voice. But it can also spoil the recording if you don’t know what you
are doing. Equalization is a fine art and needs experimentation.
Compression
of Sound and Hard Limiting

Hard Limiting a Wav in Vocal Recording |
You
will also need a sound compressor and hard limiter. The human voice is dynamic
in that it will alter dramatically in volume, creating high peaks and low
plateaus on the sound wave. This can cause inconvenience for the listener who
has to keep turning up and down the volume. The sound compressor will even out
the sound wave, creating a more consistent wave profile. A hard limiter is a
severe form of sound compression in that it simply cuts the volume to the
chosen parameter. The result is a sound wave that looks like a comb. Don’t
overdo the compression, as this will cause a horrible distorted sound to the
voice.

Other
features will come in useful such as:
Normalization:
this will amplify the soundwave as much as possible whilst retaining its proportions
without clipping.
Amplification:
This will amplify the soundwave but also permit clipping.
Noise Removal:
This will identify the sound profile of the ‘room tone’ which is the silent
aspects of the recording. Any slight hiss or hum can be removed. However, a
room with a very low noise floor, i.e. a very silent room will make the noise
removal function more effective.
Sound Analysis:
This enables the sound engineer to examine the sound profile of any recording
and make adjustments.
After
taking a look at the sound editing software, have found all have these basic
functions but are presented differently. Some also have extra features, such as
additional MIDI tools, voice changer, text to speech, sound mixing and more. Will
the narrator really need all these extra tools?
This
brings me to the next issue: the sound files that are supported.
MP3
Editor for Audio Books
Not
all audio software will save the WAV file in MP3, the required sound format for
upload onto audio book retailers. In some cases, the customer may have to pay a
license fee to use it due to software patents. However, Lame Source Code is
free and can be used with Audacity to create MP3 files for talking books. But
note: not any MPEG files will do, but MP3 192KKB in mono. This cannot be
achieved from some sound editors, not even Itunes itself (it halves the KBBS of
a mono recording degrading the quality).
Sound
Editing Software for Talking Books
In
conclusion, the voiceover narrator is spoilt for choice when it comes to
audiobook software to master a vocal recording. Some offer lots of features and
may take some getting used to. Others are free and simple to use. Bear in mind
the demands of the sound software. A sole voice is all that is being mastered,
not a complex recording project or a ten-piece band. This means that most of
the features will remain unused. I use Audacity and Lame.
Finally,
even the best recording software cannot make up for poor recording, which might
be littered with plosives, background noise or the metallic sound of a cheap
mic. A good large diaphragm condenser mic, audio interface and a soundproofroom will bring the home recording up to a professional standard more than the software
alone.
