Latency in Recording
What is Latency? – The time it takes the sound to transmit through air. ( Usually measured in milliseconds when recording audio). Latency in recording audio is described as the delay generated when a signal is routed through a digital audio workstation and connected peripherals.
How does Latency Affect Recording Audio? An example would be if a MIDI note generated on your keyboard leaves it is sent to the computers CPU processor. The corresponding sound from your software instrument is then generated by your CPU. The signal is then sent back to your interface and converted and sent out as an analog signal to your speakers for example.
