What is Audio Fidelity

I brought this up in the Home Pod argument about how important having a smart speaker is compared to having a high-fidelity audio speaker is. To elaborate on this, we felt it necessary to take the time to define what audio fidelity is and how you can experience different levels of it.

Levels of Audio

There are two main ways of determining the levels and fidelity of audio. Hz and Kbps. Hertz and Kilobytes per second.

quality soundHz – Hertz is the strength of audio. The human ear can determine and understand the audio levels of 20 Hz to 20 kHz. This defines how long and short the waves are that someone can hear.

Now we can distill a Hz into a file and then compress the sound into a sustainable range of information. Similar to how you can compress an image from 256 x 256 to 1920 x 1080p, there is a significant size difference in quality. When compressing sound, you can lose out on a lot of nuance that sounds create, from fingers on frets to catch breaths in between a vocalists solo.

Kbps – Sound files are defined by kilobytes per second. The oldest forms of audio can be anything from 32 kbps to 64 kbps like cassettes. However, the main argument that people have is between 128 and 256 or 320 kbps.

For the most part, a lot of audio comes out at 128 kbps, but with more revelations happening, a lot of people are trying to get higher fidelity audio. Because of the higher, the better.

How to Optimize your Sound System

lossless audioMany custom computers need audio cards to transmit higher quality audio because, for the most part, audio at lower levels is acceptable. So when you are getting a new audio system, you need to ensure that the speakers involved or the home audio center can consistently transmit higher quality audio.

But most people have the speakers and setups to play high-quality audio. Often when you buy better speakers, it’s not about transmittance as much as it’s balancing between bass and treble and maintaining that audio fidelity. But instead, the bigger problem is finding the appropriate mediums that are capable of transmitting higher quality audio.

Finding Media and Mediums for Higher Quality Audio

Tidal – The only reason that Tidal had any chance of competing with Pandora or Spotify was that they were stating they could sell lossless audio or audio that was devoid of compression. While some audiophiles have stood behind this claim, the difference wasn’t high enough ot merit an additional $10 price tag in an oversaturated market of freemium choices (sound familiar?)

Besides that, not a lot of people are advertising high-fidelity audio. You can notice places that fully utilize it like the nuanced audio of ESPN when they are putting microphones on their athletes, but besides these nuances, it’s hard to find great examples.
