Audio Latency Budget Calculator — Round-Trip Delay

Calculate total round-trip audio latency from buffer size, sample rate, converter latency and plugins. Get usability ratings and recommendations.

Lower = less latency, more CPU

Higher rates reduce latency

Analogue-to-digital delay (check interface specs)

Digital-to-analogue delay (check interface specs)

Number of plugins in monitoring chain

How We Calculate This

This calculator sums all latency sources in the recording signal chain to give a total round-trip delay measurement.

The formula

Buffer latency = Buffer size / Sample rate x 1000

Round-trip = (2 x Buffer latency) + A/D + D/A + Plugin latency

Distance = Total latency x Speed of sound (343 m/s)
