Audio Latency Calculator – 128 samples at 48kHz

This audio latency calculator converts 128 samples at 48kHz into milliseconds for AV sync and NDI workflows.

Essential for Dante network alignment, AES67 synchronisation, and keeping your broadcast lip-sync perfectly tight. For real-time visual calibration, use our Audio / Video Sync Calibrator or check your Streaming Latency. Explore more broadcast engineering tools for IP video and media networking.

Calculating 128 samples at 48kHz latency ms for AV Sync

Common buffer size latencies (at 48kHz):

→ Read our full guide on Buffer Size vs Audio Latency

BROADCAST VERIFIED • DANTE SYNCED
Buffer Latency 5.33 ms
Total End-to-End 10.33 ms
Latency in Frames 0.52 frames
A/V Comp Offset +10.33 ms delay
Engineering Recommendation: Add +10.33 ms of video delay to align with this audio path. This ensures lip-sync within EBU R37 tolerance.

Dante Networking Field Rules

Switch Hop Jitter

Every Gigabit switch hop adds sub-millisecond jitter. Dante Controller warns if 'Receive Latency' is set below the network's processing capability.

Clock Performance

Running high sample rates (96kHz) halves your per-sample latency but doubles network bandwidth requirements. Test for PTP clock stability.

Save for your Engineering Team

Critical for Dante network audits and SMPTE lip-sync verification.

Absolute Sync in Broadcast Audio

Digital audio adds latency at every stage: A/D conversion, internal DSP processing, and network transport (Dante/AES67). Our Audio Latency Calculator models these stages to define a total millisecond delta.

Dante Network Hierarchies

In managed IP networks, the number of 'hops' (switches) determines the required jitter buffer. A 10-hop Dante route on a corporate WAN requires significantly higher device latency (5-10ms) than a single-switch production rack (0.15ms).

A/V Delay Compensation

Since audio typically lags video due to processing, it is common to delay the video signal to match. Our tool calculates the exact A/V compensation offset in both ms and frames for any project frame rate.
