Hey Labfans, today we are doing a very special series of threads that will help us evaluate encoding/decoding lossy media formats.
- We will use Sonnox Fraunhofer Pro-Codec to achieve this. The pluggin is one of a kind. It offers real-time streaming (and offline) of the most common lossy and lossless media formats.
- For more information visit :http://www.sonnoxplugins.com/pub/plugins/products/Pro-Codec-Product_Info.htm
- From A mixing/mastering perspective Fraunhofer is priceless, it can help us ‘bypass’ the format by mixing through it, at least to some degree that is.

MP3 – 320 – High Quality Codec
Well the gif image limits the modulation speed, its way faster in reality.
This is what mp3 does to your FR, the definition of destruction.
Most extreme phase I’ve seen in my life.
What is important to understand is that the phase such as this is completely identical within the L/R, in order to work,. Since the format is a end-media format that won’t be introduced for further processing the phase will not matter in most cases.
First let me note that my box readings above had a bug, none the less the plot is accurate.
What we see is a very unnatural THD specially over the fundamental, we can also see that irregular harmonic orders are formed which is not a good thing.
Yes, no compression unlike popular belief.
Anticipated roughness from frequency modulations …
What we see overall is the destructive properties of this media format.
It does not compress audio, it deforms its response and distorts it.
Q: Hey I’f I’m distorting I must be compressing right ?
A: Not always, in order for a drastic compression reading to be created, we need higher percentages.
Personal Quote: I wouldn’t want any of my work going through that.
