Digital summing

In a digital audio workstation or DAW, basic track summing settings are assigned by default when you open a new project. However, you can change the settings by assigning bus and aux channels to the DAW mixer.

You can route individual audio and midi tracks to the master track by using aux and bus channels. This is how summing is done in DAWs.

Analog summing

While DAW mixers are the most common way of summing in audio recording, there is a debate among producers is that analog summing is better than digital summing.

Analog summing is done by adding analog hardware to your DAW. Hardware like Dangerous D-Box, allows you to send your interface’s analog outputs to the analog summing box and then return summed channels back into your interface from that analog box.

Analog vs. Digital Audio Summing – Which is better?

So, the question arises, between analog and digital summing which is better?

Well, analog summing adds some warmth to your final mix. If you want to add that vintage analog warmth in your mix then you should add a hardware summing box in your production line.

People say, audio tracks summed in the digital domain listen to some harsh cold as compared to analog summing.

However, you can go well with digital summing powered by your DAW. After all, there are plenty of mixes summed digitally yet deliver good audio quality.

If you give time to your mixes then you can get a better quality track. The easy approach to get better results in any type of summing is to listen to the tracks you love and try to mix like that.

That’s it…
