Hello everyone!

I am a very very new user ( new to programming in general) and I want to use PD to create a simulation of how a person with hearing loss would hear specific audio files. To do that I want to create an EQ that would accept values from an audiogram compare its values with those of a reference audiogram (of a normal hearing person) apply the reductions in the frequencies where the person has reduced hearing and then playback the result. (Ideally I would like to have a spectrum analyser on the input and output as well.

Any tips on how to start? or any existing patches that could be helpful while building this? I have already watched tutorials on how to get started with simple things but this is a bit more complicated and I feel that the resources I have are not very helpful.
Any help would be greatly appreciated!

@Azoso Hello and welcome to the forum.
It can all be done of course.
I would recommend starting with an installation of Pd extended if possible, rather than Vanilla, as at least one of the tools that you need (spectrum analyser) is then immediately available in the download.
If you are using a recent 64-bit mac os then that will not be possible, and things get more complicated.
You will then need to use "help" "find externals" from the Menu of Pd and download all the externals.

You can always switch to Vanilla later when you know more about the workings of Pd "under the hood".

The spectrum analyser (probably the most difficult part of your project) can then be created instantly by placing an object [spectrogram~-help] in your patch. Then right-click it to open it.

You can see it working by connecting an [adc~] to the [spectrogram~] object instead of the [noise~] object...... and you will be inspired to continue.

Then change [spectrogram~-help] to [spectrogram~] so as to use it in your patch.

Come back when you get stuck!
David.
