Audio Buffer Latency Calculator
The tradeoff behind every buffer size setting
Digital audio interfaces process sound in small chunks called buffers rather than continuously - larger buffers reduce the risk of audio glitches and dropouts, but at the direct cost of increased latency.
Worked example
For a 256-sample buffer at a 48,000 Hz sample rate:
Latency = (256 / 48000) x 1000 = 5.333 ms
| Use Case | Typical Buffer Setting |
|---|---|
| Real-time recording/monitoring | Small buffer (64-256 samples) for low latency |
| Mixing/mastering (no live input) | Larger buffer (512-1024+ samples) for stability |
Noticeable delay between playing a note and hearing it back through software processing becomes distracting for musicians during live recording, which is why buffer size is typically minimized specifically during tracking sessions.
