ANALOGUE -/ DIGITAL

Understanding the
Pro's & Con's


Analogue / Digital

Analogue

Analogue sound is a pure
sine wave with all sound charateristics.
File size is heavy and editing is restricted


Digital

Digital sound is numerical
snapshot of the analogue sin wave.
File size is lite and highly editable.


Convertion

Sample rate / mathmatical
interprutation is key to ensuring the
science of the replication is accurate.

Analogue purist or Not!

Frequency & Amplitude

Understanding the pro's & con's between analogue & digital sound in music and from a guitarist's perspective is not without controversy. In the following paragraph's we will try to open up the subject to create the necessary awareness.

Music and speech vary continuously in frequency and amplitude. In the same way, analogue signals can vary in frequency, amplitude or both. Digital signals are a series of pulses consisting of just two states, ON (1) or OFF (0). There are no values in between. Digital signals carry more information per second than analogue signals. This is the same whether optical fibers, cables or radio waves are used. Digital signals maintain their quality over long distances better than analogue signals.

The potential fidelity of an analog recording depends on the sensitivity of the equipment and medium used to record and playback the recording. Among other factors, digital audio fidelity heavily depends on the rate at which the recording equipment sampled the original sound wave over a specified increment of time. Even with the newest technologies and techniques, digital audio still cannot create exact replications of an original sound wave.

Many times, digital audio companies try to hide this fact with fancy words like “Uncompressed” and “Lossless”. These words are very misleading as all digital audio features some compression and loss of the original signal. However, even the best trained human ear may not be able to tell the difference between a high quality digital signal and an analog audio signal.

Digital convenience sometimes comes at the cost of fidelity. In mobile/casual listening environments, or if average quality playback equipment is used, the fidelity offered by digital audio may be sufficient for most people. However, for those audio purists that want the very best fidelity possible, and use really high quality playback equipment, digital audio may not be the answer.


Music software

Guitar synthesizers have been around since the 70's and after 30 year's of MIDI development we are now living in an incredible time for music software and synthesis.
A high quality recording of a valve amp in an expensive studio is going to provide the ultimate richness of tones. However, it is not often if ever we find ourselves in this fortunate position.
More affordable and accessible alternatives can be provided within the "home studio" set-up.
Making sense of all of the different routes into this digital environment can need a strong grasp of whats on offer within products and technologies in relation to what is trying be achieved. There are a number of affordable and flexible options out there.


Digital Sound

Environment

Bit rate is the number of bits that are conveyed or processed per unit of time. "CD Quality" is defined as 16-bit/44.1kHz. Many of the Analog / Digital Converters that come standard on today's audio interfaces are capable of 24-bit/96kHz which is an even higher quality. When comparing A/D Converters it would be common to see them displayed like this:
24-bit / 96kHz - where 24 is the Bit Depth and 96kHz is the Sampling Frequency.

There are a number of different points in the chain of sequence where an audio can become or be effected by digital. From a guitarists standpoint what makes the best sense in the balancing act between a producing a good sound and getting the most out of the software that is available? And at which point can a conventional guitar file be superseded by a MIDI guitar file? Or which software solutions produce the best results for specific tasks?

Guitar sound in conjunction with how it is approached can take a number of different directions and equally produce a number of different results. It can be all about what you are looking for and what you enjoy.

From digital guitars (or digital applications of the guitar) to guitar synths & MIDI guitars there are a number of varying forms and systems of approach to the software arena. To simplify some of the main reasons for this are to;

  • Access sound software
  • Communicate to education software
  • Control composition software

Standards


Ironically since the advent of CD's and consequently Mp3's the regular listening standard of music is in a digital format. Vinyl & tape provided the pure analogue sound of a sin wave, though vinyl is seeing a resurgence of popularity it will probably not be more than a boutique industry.
Even though how we listen to music today is mostly digital the guitar environment is complicatedly poised between the two formats, this is based on a number of delicacies related to the science of sound.

DIGITAL Sound

MIDI or Wav. files can both get processed with a digital sound output. A Wav. file (analog sinwave) utilises software that processes a sound whereas a MIDI file needs to be provided a sound source (tone) before any processing.


Sound Source

A Wav. file contains sound information that can then be further processed. A MIDI file contains mathematical values that need a sound or tone allocated, the file size is lighter/faster but needs to be allocated voicing.


SAMPLE Libraries

A MIDI file arriving in a software device can be allocated to any sounds that are made available. From synthesizer tones to sample libraries that could be anything from a drum to a guitar.

Brands & Solutions

As digital technology is evolving there have been various attempts at providing solutions. A number of products have come and gone and even today there seems to be no obvious overriding solution.
The potential of digital and MIDI guitars has seen major brands, even the iconic Fender & Gibson brands have made attempts. All be it if the technologies are being provided through specialist business associations.
As well as the guitar brands cited below Line 6 is a company that has always pursued digital solutions. line6.com →



Guitars addressing Digital

Addressing the pro's & con's of the changing environments between analogue & digital for guitarists is a complex subject with no exact answers. It's all a question how you want to utilize the environment of creative technology!
Just to be clear the division of where analogue turns into digital can be carried out at numerous junctures...different systems/solutions approach this differently. Where the best solution lies is still emerging within the evolution of this technology.
Hopefully this page has helped in getting a general understanding within the standards & differences of analogue / digital for guitar...playing...recording...& getting the most out of a creative experience with a guitar.
