The Quality Of Sound Found In Mp3′s
With all the technological advancements we’ve seen over the last few years people’s standards for video and sound quality has increased. One is less to listen to cassette tape or record players unless you just have to because the quality isn’t as clear and crisp as a CD and mp3. Programs like iTunes provide very good audio quality from downloaded songs or burned CDs. What is it about the mp3 format why the audio quality is so much better?
MP3, designed by the Moving Picture Experts Group, is an audio-specific format that was created as part of its MPEG-1 standard and later extended in MPEG-2 standard. A patented digital audio encoding format it uses a form of lossy data compression. MP3 is a common audio format for consumer audio storage and a de facto standard of digital audio compression for the transfer and playback of music on digital audio players.
During the creation of an MP3 file there is a trade-off that takes place between the amount of space used and the sound quality of the result. A bit rate is something which specifies how many kilobits the file may use per second of the audio. Usually the creator is allowed to set a bit rate, and the higher the bit rate, the larger the compressed file will be and it’s the sound will also be closer to the original file.
In addition to the bit rate of an encoded piece of audio, an mp3 file’s quality also depends on the quality of the encoder itself as well as the difficulty of the signal being encoded. Although the mp3 standard allows freedom with encoding algorithms, different encoders can feature quite different quality even with identical bit rates. Back in 1998 mp3 at 128 kbit/s provided lower quality than AAC at 95 kbits/s. Quality is dependent on the choice of encoder as well as 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.
