Compression of audio files – The ultimate quality damage

Many people use compression of audio files for their convenience. However, our research shows the result as the ultimate quality damage.

Compression of audio files: Not all audio file formats are equal in terms of file compression. Compressing audio files saves space on a medium, and improves internet download speed.

An audio file format is a data format that is used in computers to digitally store sounds, music, or voices.

Many technical standards exist at the level of file formats.

Compression of audio files, example with mp3 format

The most used audio formats currently are mp3 , wma (better audio quality than mp3 with a smaller file size), and aac (superior to mp3 and wma, but developed only by Apple).

Formats: Last name:  Note:

.mp3

MPEG layer 3 Configurable audio compression format
.wav WAVE  (Microsoft) Standard format under Windows operating system
.wma WMA  (Windows Media Audio) Format under Windows system, allows continuous reading “streaming”
.aif AIFF Standard format under Apple operating system
.aac AAC Extension of MPEG-2 Improved in MPEG-4. ACC is Apple’s preferred codec (iPod, iTunes, etc.)

These three formats (mp3, wma and aac) are  compressed with a loss , it will therefore be necessary to take this into account for an optimal result when playing a song.

When we use compression formats, we lose quality but we gain portability which is more than sufficient for the general public. This is much less acceptable for a music lover, specialist, sound engineer, or DJ.

To conclude, all kinds of sources can be mixed together. You can mix with vinyls, CDs, mp3 files or other, mini discs, analog synthesizers or sequencers etc.

They should be chosen according to the DJ techniques you want to use (scratching, effects, etc.), technical constraints during the mix (equipment provided, location of the service, etc.) but above all the sound quality of the sources.
