"I record music."

Translation: 저는 음악을 녹음합니다.

[LiKenun]

녹음←록음←錄音

The characters literally mean record sound, so this verb can only apply to audio recording.

The hint for record does not match with any possible answers. Android

Try sound recording.

Like #Likenun has explained 녹음 applies only to sound (audio)
