MP3 facts and specifications

MP3 facts and specifications post thumbnail image

Here, we will talk some basic facts about MP3.
Effects of occlusion-
When two sounds are played simultaneously, the stronger sound conceals or “masks” the softer tone. One sound is louder than the other. Know that when the sounds are close in frequency, they may seem distinct from one another.
However, if the two sounds are sufficiently different, they may be distinguished from one another. Disk space is conserved by removing unwanted recordings. Temporal masking and auditory masking are two phenomena that are best understood via analogy.
The shape of a flying bird’s outline may vary from that of the surrounding sky. However, when the bird is directly in front of the sun, its brightness completely obliterates the outline. When the bird flies to the opposite side of the sun, it is once again visible to the naked eye.
The same concept applies to mp3 encoding, when masking techniques are used.
A pair of stereo speakers joined together-
Joint stereo is usually enabled by default in most encoders, although it is an option. The MP3 encoding procedure does not depend on it. The ability to combine real stereo and monophonic sound in stereo sound is provided to users when stereo sound is enabled.
The mp3 format encodes extremely low and very high frequencies in mono, which saves space in the final file.
Auditory threshold as low as possible-
Various elements of audio have a combined effect of making the human ear insensitive. Most audio transmissions span a frequency range audible to humans at first. Between 2 and 4 kHz, the human hearing range is most sensitive.
The typical hearing range is between 20 Hz and. 20 kHz. Most individuals can’t hear tones higher than 6 kHz as they age due to a decrease in their listening ability. MP3 encoders can ignore frequencies outside of this range.
