How is the MP3 music format developed?
A specific process is used when music recordings are compressed into an MP3 format. First, the machine or software detects any sound effects produced by the surroundings or such noises that are deemed unwanted to the human ear and then such sounds are eliminated from the recording. And then, the music is charted into the following format.
For instance, typical music recorded in a CD format takes 30MB at least. However, when this file is compressed into an MP3 format, even if the bit rate is kept high, around 320kbps, the overall file size comes down to around 10-15 MB at maximum. And as you can notice, this is a huge loss in data, almost half of the original audio file.
What are the drawbacks of such formatting?
One of the disadvantages of such formats is that most of the time, the human ear can detect this elimination of sound effects, which feels unpleasant to the ears, often producing low-quality music. The term bit rate is used here for determining the quality of the sound. The lower the bit rate of the audio format, the lower the audio quality. This is because it has a bigger portion of the audio ripped off.
What is lossless sound, and how is it produced?
Another type of music file compression keeps intact every bit of the audio from the original recording while reducing the overall size of the file to a somewhat writable extent.
This type of compression is often termed as ‘lossless sound’ or ‘lossless audio’ format. And an example of such compression can be traced by the following instance. Suppose a CD holds an original recording file size of 100 MB; when compressed into the lossless format, every bit of the recording and audio is kept intact. In comparison, the size reduces to around 60-70 MB, which is comparatively less, but the difference in quality from an MP3 format can be easily noticed.
How is such a type of compression made possible?
A complex algorithm is used when the software detects sound patterns from a particular file. For instance, if the audio file is in the form of a series of numbers laid in a particular pattern, the MP3 format counts the number of digits or its storage units. It then eliminates everything unnecessary from the file to deliver the clean MP3 format. Whereas in the case of the lossless format, the system tracks the patterns and then sorts the audio file into a format. Thus, taking an overall less size from the original but keeping the raw quality intact.
Which devices support a lossless format?
To run a lossless audio format, you will need to use a device or application that supports such a format. For example, some players who support the FLAC lossless sound format are Colorfly C3, C4, Creative Zen X-Fi 2, TRAXMOD, Trekstor Vibez, VEDIA A10, B6 and many more. Also, Apple Inc. uses its type of lossless audio format named ALAC supported in Apple iPods and other Apple music devices.
