Depending on what you are trying to do, you will want to use either:

- Sound::readData()  
[https://fmod.com/resources/documentation-api?page=content/generated/FMOD\_Sound\_ReadData.html#/](https://fmod.com/resources/documentation-api?page=content/generated/FMOD_Sound_ReadData.html#/)

- Sound::lock()
