Hi,

You are able to extract PCM data without playing the sound: [FMOD Engine | Advanced Core Api Topics - Extracting Pcm Data From A Sound](https://www.fmod.com/docs/2.02/api/advanced-core-api-topics.html#extracting-pcm-data-from-a-sound) would this be a valid option?

Is this a similar issue as you were experiencing before: [Visualizing both classic Loudness x Time and Spectrogram](https://qa.fmod.com/t/visualizing-both-classic-loudness-x-time-and-spectrogram/22551)?
