General Audio Tips

Posted by on in General Audio Tips

We all know WAV is better of course (I hope we do!!) - Some people claim they can not hear any difference between a 320kbps mp3, and a full WAV, but as a producer and audiophile, I find it very easy to spot the difference, especially if a DJ is playing mixed mp3's and WAVS. - Regardless of whether you can hear the difference, have you SEEN it?

Below is some screen shots I found, showing the averaged peak frequency analysis of the same piece of audio.



WAV



320kbps mp3


As you can see (and hopefully hear if you were listening!) - The mp3 has a artificial boost in amplitude (volume) between 4-6khz, and a sharp cutoff just before 20khz - this is why on a small car system for example, things sound OK, but when on larger more precise systems, you can hear the difference..
