To me, audio papers are academic essays presented in sound format or a podcast that provides a more aesthetic sense of sound.
This reminds me of my assignment back in Australia last semester. It was a podcast, not an audio paper, but I guess they have similarities. So I am quite confident that I can create something interesting in the end. I may take a look at what I did from the podcast and see if I can bring some ideas into the audio paper. For your reference, this is the link to the podcast I have made:
Idea-wise, I think I will keep the same topic as mentioned in the previous blog: Exploring how the sound “ɑː” (ah) constructs meanings in different scenarios and cultures. However, the topic seems to be too broad so I need to narrow it as Milo suggested. I have not thought of any specific things on the topic but I can start doing some research around it.
