With all the advancements in technology we’ve experienced over the last few years people’s standards for video and sound quality has increased. One won’t listen to cassette tape or record players unless you just have to for the quality isn’t as clear and crisp as an mp3. Programs like iTunes provide great sound quality from downloaded songs or burned CDs. What is it about this 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.
When one creates an MP3 file there is a trade-off that will take place between the amount of space used and the sound quality of the result. A bit rate specifies how many kilobits the file may use per second of the audio. Typically the creator is allowed to set a bit rate. Therefore the higher the bit rate, the larger the compressed file will be and the closer it will sound 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.
The quality being perceived can also be influenced by a number of things such as: listener attention, listening environment (ambient noise), listener training and listener audio equipment (i.e., speakers, sound cards, headphones..). With MP3′s great quality there is something else to keep in mind. Now your favorite You Tube videos can be converted into MP3 format.
