The Quality Of Sound Found In Mp3's
Go to: Previous Article Next Article
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.
The quality of an mp3 file not only depends on the bit rate of an encoded piece of audio but also 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 different quality even with identical bit rates. In 1998 mp3 at 128 kbit/s provided lower quality than AAC at 95 kbits/s. Quality can depend 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.
