The Quality Of Sound Found In Mp3’s
The advancements in technology seen over the last few years have caused people’s standards for video and sound quality to increased. The typical music lover won’t listen to cassette tape or record players unless it’s a special preference because the quality isn’t as clear and crisp as an mp3. Programs like iTunes provide great sound quality from burned CDs and downloaded songs. What is it about this mp3 format that causes the audio quality to be so much better?
MP3, which was designed by the Moving Picture Experts Group, is an audio-specific format that was created as part of its MPEG-1 standard then later extended in MPEG-2 standard. It is a patented digital audio encoding format uses a form of lossy data compression. MP3 is a common audio format used for consumer audio storage as well as a de facto standard of digital audio compression for the transfer and playback of music on digital audio players.
When creating an MP3 file there is a trade-off that takes place between the amount of space used and the sound quality of the result. There is what’s called a bit rate, which specifies how many kilobits the file may use per second of the audio. The creator is typically allowed to set a bit rate so the higher the bit rate, the larger the compressed file will be. Then generally the closer it will sound to the original file.
Apart from the bit rate of an encoded piece of audio, an mp3 file’s quality also depends on the quality of the encoder itself and the difficulty of the signal being encoded. The mp3 standard allows freedom with encoding algorithms, but different encoders can feature quite different quality even with identical bit rates. Back in ‘98 mp3 at 128 kbit/s provided lower quality than AAC at 95 kbits/s. Quality is dependent on the choice of encoder and the encoding parameters.
Quality perception can also be influenced by a number of things such as: listening environment (ambient noise), listener attention, listener training and listener audio equipment (i.e., speakers, sound cards, headphones). With MP3’s great quality there is something else one should keep in mind. It is now possible to convert your favorite You Tube videos into MP3 format.
