Summary

### Summary
– Audio interfaces help computers exchange digital audio signals with analog and digital audio gear.
– They perform digital signal exchange, analog signal conversion, and have multiple input/output channels.
– Low latency is crucial for a smooth recording experience.
– Important points to consider when choosing an interface: low latency, balanced outputs, high impedance connections, and more inputs or outputs.

Highlights

• Audio interfaces provide a way for computers to exchange digital audio signals with external analog and digital audio gear.
• They convert analog signals into digital ones that computers can process and vice versa.
• Important functions: Digital signal exchange, Analog Signal Conversion, Input/Output Channels, Low Latency

Key Takeaways

• Audio interfaces are essential for recording, mixing, and playing audio.
• They amplify quieter analog signals like vocals or electric guitars to usable line levels.
• The quality of the digital signal depends on sampling rate, bit depth, A/D and D/A conversion.
