This paper explores the connection between podcasting and broadcasting theory. In podcasting

sound transmission breaks free from traditional norms

allowing for more flexible language expression. Hosts span both professional and non-professional groups

and technology enriches soundscapes

enabling the dissemination of subcultural elements. This prompts broadcasting theory to address practical issues: clarifying the value assessment and ethical boundaries of sound data

expanding the scope of its discipline

and exploring the impact of soundscapes on the digital industry. This is not a simple adaptation of theory to practice

but rather a process of mutual interaction and co-development between the two.
