Normalizing Audio in Convolution Node?

[Casmat]

Hey!

How do I normalize audio that is entered into the convolution node? Is it possible to do so?

Thanks!

[Lindon]

@Casmat normalising requires you to look at all of the audio in the track and identify the peak value...cant do that to a real-time fx like convolution....

[Casmat]

@Lindon i was hoping to do the detection while the sample file is "loading" into the convolution. Thought of getting the samplefile from the node itself and analyze that with some scripting, but cant seem to work out how. I'm trying to find a way to compensate for varying convolution sample volumes a user could import.. any ideas?

@Casmat have you tried using the file_analyser node?

attach a gain control to let the user set the gain.

Like @alhug said, the file analyser node is what you need.

@Christoph-Hart wow.. hise sure is amazing.. as with you @Christoph-Hart and @alhug and @Lindon! Much thanks!

[alhug]

@Christoph-Hart what a great tool and thanks for the example. if file_analyser could also do LUFS or RMS that would be amazing. Analysing a longer audio file for true peak, like a noise layer sample for example, is not that useful.

@alhug Couldn't you do it with a snex or faust node, just store the peak values over time and root the mean of the squares? I'm asking, I have no idea myself, I've yet to dive into snex/faust.
