In an analogue console the channel signals are mixed together at the group, aux or main stereo mix busses. This operation is simply performed by adding the instantaneous signal voltages together. When summing your tracks in a digital system such as your DAW, the same thing is achieved by adding corresponding sample values together. So far so good, but why do more and more people take the hard road and invest in a summing box, plus a bigger converter instead of simply pressing the „bounce button“ in their DAW? The answer is: SOUND.
At the end, everyone has to decide personally if he agrees, but there are some scientific explanation which I do not want to withhold from you:
Analog technique operates with infinitely high resolution whilst a digital system is always limited to the word length and sample-rate. This limitation causes rounding errors and digital distortion. Theoretically when mixing ITB (in the box), the more processing steps you have and the more tracks you add, the more errors will be summed together.
The fact, that the signal is routed thru hi-end analog components, such as the huge Haufe transformers in the Sonic Summarizer PRO, makes a mix sound better to the human ear. Adding a good piece of analog gear to the master bus or your stem mixes can really help. It adds some nice harmonic distortion and often makes a mix sound warmer and just more comfortable.
