I’m studying a module in audio software dev and university and I have began to prototype the different elements I will need for my final project, an LUFS meter. I have been watching The Audio Programmers tutorials to get an idea of the first part of the LUFS meter Filtering.
https://www.youtube.com/watch?v=YJ4YbV6TDo0&t=626s (Tutorial I followed)
Unlike the tutorial, I did not implement a means for the user to change the cutoff fq and Q as these are not user controlled. But processes the buffer of audio goes through before the loudness calculation.
I want these to happen as "background’ processes which do not effect the signal coming from the speakers (the user can hear their track whilst viewing a UI detailing the LUFS level) I may have to implement the filter in a different place, or create a copy of the audio (which will be uploaded into the app) which goes through the LUFS stages and one which gets played directly.
However, when I try to test the implementation of the filter (LUFS uses a high shelf and then high pass) the plugin will not run in live, when I drag it to an audio track it opens xcode and then crashes live and my audio drivers. I am also unable to open it as a standalone app… it says audio is muted to prevent a feedback loop.
Please find attached my code… any help would be appreciated!
