Audio Buffer Latency Calculator
Calculate one-way buffer latency from sample rate and buffer size, and convert between samples and milliseconds.
Frequently Asked Questions
- How is buffer latency calculated?
- One-buffer latency (ms) = buffer size in samples ÷ sample rate × 1000. This is the time it takes to fill one audio buffer at the given sample rate — it does not include driver, OS, converter, or other round-trip latency.
- Does this measure my actual audio interface latency?
- No. This is buffer-time math based on sample rate and buffer size only. Your actual measured round-trip latency also depends on your audio driver, operating system, USB/Thunderbolt overhead, and converter latency, and will typically be higher than the buffer-time estimate.
- How do I convert samples to milliseconds?
- Use the Samples ↔ Time tab: milliseconds = samples ÷ sample rate × 1000, and samples = milliseconds ÷ 1000 × sample rate.
