What are the differences between a DI box and an audio interface, and which one would be more suitable for my recording needs?

A DI box is used to convert high-impedance signals from instruments like Guitars to low-impedance signals for recording. An audio interface is used to connect multiple audio sources to a computer for recording. If you mainly record instruments, a DI box would be more suitable. If you record multiple sources or need more control over your recordings, an audio interface would be better.
