What is the Main Difference Between Analog and Digital Audio?<\/h2>\n\n\n\n

Analog mediums<\/strong> use recording methods <\/strong>that replicate <\/strong>the acoustic soundwave <\/strong>perfectly. Examples of analog mediums <\/strong>are tape recorders <\/strong>and vinyl players<\/strong>.<\/p>\n\n\n\n

Analog synths<\/a><\/strong> and analog compressors<\/a><\/strong>, for example, utilize control voltages <\/strong>and components <\/strong>such as tubes <\/strong>and voltage controlled amplifiers <\/strong>to create <\/strong>and emulate synthesized sounds <\/strong>and FX<\/strong>. To summarise how analog equipment <\/strong>such as these work<\/strong>, a direct current <\/strong>is sent around <\/strong>the circuitry <\/strong>and interacts <\/strong>with transistors<\/strong>, transformers<\/strong>, and other electrical components <\/strong>to create desired effects <\/strong>such as tube distortion <\/strong>or equalisation<\/strong>.<\/p>\n\n\n\n

Analog recording <\/strong>uses a microphone <\/strong>to convert <\/strong>the acoustic soundwave <\/strong>into an electrical analog signal<\/strong>. This signal <\/strong>was then and imprinted directly <\/strong>onto analog master tapes <\/strong>(like a cassette tape<\/strong>).<\/p>\n\n\n\n

Digital mediums<\/strong>, however, convert <\/strong>the acoustic soundwave <\/strong>into digital 1s <\/strong>and 0s<\/strong>. This is done by converting <\/strong>a recorded acoustic soundwave <\/strong>into an analog signal <\/strong>(yep, really), but then dicing up <\/strong>and sampling <\/strong>that signal <\/strong>at a sample rate<\/a><\/strong> and bit depth<\/a><\/strong> that you specify<\/strong>. <\/p>\n\n\n\n

Sample rate <\/strong>& bit depth <\/strong>work together to create a total bandwidth <\/strong>that defines <\/strong>the quality <\/strong>of the digital signal<\/strong>.<\/p>\n\n\n\n

How closely <\/strong>the digital signal recreates <\/strong>the acoustic soundwave depends <\/strong>on the amount <\/strong>of bandwidth<\/strong>. <\/p>\n\n\n\n

More bandwidth <\/strong>= more accurate reproduction<\/strong>. You wouldn’t <\/strong>be able to enlarge <\/strong>a low-resolution image <\/strong>and see it in better quality<\/strong>. It’s the same principle <\/strong>with audio<\/strong>!<\/p>\n\n\n\n

Above<\/strong>, the analog soundwave represents <\/strong>the original soundwave <\/strong>in every way<\/strong>. However, the digital soundwave <\/strong>is only representing <\/strong>the segments <\/strong>of the sound wave <\/strong>that it’s sampled<\/strong>.<\/p>\n\n\n\n

Here’s a closer look <\/strong>at the digital representation <\/strong>of a soundwave<\/strong>.<\/p>\n\n\n\n

\"\"
Increasing sample rates, Source: iZotope<\/figcaption><\/figure><\/div>\n\n\n\n

You can see <\/strong>in the image above <\/strong>that higher sample rates <\/strong>allow you to reconstruct <\/strong>the acoustic soundwave <\/strong>in much more detail<\/strong>.<\/p>\n\n\n\n

The accuracy <\/strong>of analog gear reproducing acoustic soundwaves depends <\/strong>on the sensitivity <\/strong>of the equipment<\/strong>. This is true <\/strong>for both recording <\/strong>and playback equipment<\/strong>.<\/p>\n\n\n\n

Digital audio accuracy depends <\/strong>on the rate <\/strong>of sampling chosen <\/strong>by you<\/strong>. <\/p>\n\n\n\n

However, digital audio cannot create <\/strong>a perfect reproduction <\/strong>of the acoustic soundwave<\/strong>. This is because <\/strong>the amplitude values <\/strong>of an acoustic soundwave don’t always match <\/strong>the digital values <\/strong>(bits<\/strong>) available inside digital systems<\/strong>. For a more detailed explanation<\/strong>, check <\/strong>out our bit depth <\/strong>and sample rate articles <\/strong>in the first paragraph<\/strong>!<\/p>\n\n\n\n

It is worth noting, however, that even the most trained ear <\/strong>may not <\/strong>be able to call <\/strong>a digital soundwave out <\/strong>for its imperfections <\/strong>when compared <\/strong>to an analog wave<\/strong>! <\/p>\n\n\n\n

What Are Digital to Analog Converters?<\/h2>\n\n\n\n

Okay, so we’ve covered <\/strong>what analog <\/strong>and digital mediums <\/strong>are. But I’m sure you’re wondering how <\/strong>the digital 1s <\/strong>& 0s <\/strong>stored on CDs <\/strong>or WAV<\/a><\/strong> files actually become sound<\/strong>. <\/p>\n\n\n\n

That sorcery boils down to digital-to-analog converters <\/strong>(DAC<\/strong>). That’s right. We turn <\/strong>our digital signal <\/strong>that our digital equipment <\/strong>has worked so hard <\/strong>and turns <\/strong>it back <\/strong>into analog<\/strong>.<\/p>\n\n\n\n

A DAC <\/strong>takes your digital 1s <\/strong>and 0s <\/strong>and transforms <\/strong>them into an analog audio signal<\/strong>, and then sends <\/strong>that analog signal <\/strong>to an amplifier <\/strong>before it reaches <\/strong>your speakers<\/strong>. <\/p>\n\n\n\n

So, when you listen <\/strong>to your next digital recording <\/strong>you can rest easy knowing <\/strong>that you\u2019re listening <\/strong>to an analog signal <\/strong>that has been converted <\/strong>from a digital one<\/strong>.<\/p>\n\n\n\n

The process looks a little like this:<\/p>\n\n\n\n

  1. You record your vocals through your mic & your microphones recieves the sounds as analog audio signals.<\/strong><\/li>
  2. Your recording equipment uses analog-to-digital converters (which is the process we spoke about in the previous segment) by use of sample rates and bit depth to capture the analog signal to a digital format for storage as a digital audio file.<\/strong><\/li>
  3. When you play the digital file back, a DAC decodes the digital signal and converts it back into analog audio.<\/strong><\/li>
  4. Finally, your DAC then sends the converted analog signals to an amplifier – an from there to your speakers.<\/strong><\/li><\/ol>\n\n\n\n

    With this in mind, any Mixxed<\/a><\/strong> WAV samples <\/strong>you download <\/strong>will go through<\/strong> the DAC process <\/strong>too! <\/p>\n","protected":false},"excerpt":{"rendered":"
