Thank you very much.
I feel a bit strange about the following ones:
作家 Source
I think a 作家 of radio should be a
構成作家, not a
song/music writer.
脚本構成 Source
脚本構成 seems more like
Script Planner (構成作家/構成)
音源制作 Source1 Source2
My understanding of 音源 here is inst ver of songs which played background in a live event. Anyway I don't think it should be "sound generator". (Koji Nakagawa, Takafumi Sato, Takuya Hosaka & Tomohiro Kashiwaya are Sound Producers/Directors at BNSI/Lantis/NIPPON COLUBNIA)
音声 Source (special theater staff)
Seems more like
Sound.
