Dangers of using MP3 with Pro Audio

Using MP3 Audio files can damage your Speakers! We recommend using MP3 files for background music or very limited use.


MP3 is a type of file compression, used to significantly reduce the file size of recorded audio.

When an MP3 file is created, an algorithm removes data from the original audio, while retaining intelligibility of the audio file.

When the MP3 file is played back, the algorithm is used in reverse, attempting to predictively add waveforms back into the audio.

This concept of 'intelligibility' is based on human perception; essentially it's tricking your mind to ignore parts of the audio that is missing. Unfortunately this has no basis for use in the professional audio industry, where accurate sound reproduction is vital.

An MP3 file differs from the original audio waveform, with such issues as:

· Poor frequency response.

· Reduced stereo separation.

· Reduced dynamic range.

And most notably:

· Added distortion.

· Glitches and digital artifacts.

These factors compound when played at high sound pressure level, resulting in audio which is dangerous for a speaker to reproduce. MP3 files can momentarily produce waveforms such as pure square waves, which are incredibly destructive to speaker voice coils.



Superior alternatives to MP3 files include:

· WAV

· AIFF

· FLAC
