what it all means

Terminology

 

High-definition as defined in Wikipedia

“High-definition television (HDTV) provides a resolution that is substantially higher than that of standard-definition television.”

What this means in english: current high-definition televisions need to be capable of one of the following resolutions, 720p, 1080i or 1080p. with 1080p being the best of the three.  almost all current televisions are at least capable of a 720p resolution.


 

4K resolution as defined in Wikipedia

“Several 4K resolutions exist in digital television and digital cinematography. The term 4K refers to the horizontal resolution of these formats, which are all on the order of 4,000 pixels.”

What does it mean: 4K is a new resolution format that will be mainstream as the new standard in televisions.  4K has four times as many pixels overall than the current 1080p HDTV. Making for a superb video and image experience.


 

MP3 as defined in Wikipedia

“a patented encoding format for digital audio which uses a form of lossy data compression. It is a common audio format for consumer audio storage, as well as a de facto standard of digital audio compression for the transfer and playback of music on most digital audio players.”

What’s it to you? MP3 audio files are used everywhere and supported by essentially everything.  Chances are if you use digital audio than you have some MP3 files in your system.  The major drawback MP3 and similar audio files is that they are a lossy format.  See below for an explanation of ‘lossy


 

Lossy compression as defined in Wikipedia

“”lossy” compression is a data encoding method that compresses data by discarding (losing) some of it. The procedure aims to minimize the amount of data that needs to be held, handled, and/or transmitted by a computer.”

So what? Any lossy format compromises the audio quality of the original recording meaning that even with perfect hearing you would not ever hear the music as it was intended for you.  It’s like buying a car with punctured tires, it will work but not really well.

Can you hear the difference? This is the question that is asked.  The answer is YES for the average person, with good hearing.  For more information on hearing please see your Otolaryngologist or an Audiologist to determine what your frequency range is.


 

FLAC as defined in Wikipedia

“Free Lossless Audio Codec) is a codec which allows digital audio to be losslessly compressed such that file size is reduced without any information being lost. Digital audio compressed by FLAC’s algorithm can typically be reduced to 50–60% of its original size, and decompressed into an identical copy of the original audio data.”

So why lossless?  Lossless as its name implies recreates the original recording meaning that you have everything that was intended for you to hear in the file.  So even if you don’t have perfect hearing you will hear more detail in a lossless format.
