SoundSpeedGun: Open-Source Latency Test Tool

Easy to use Mac application to measure microphone latency, helping audio engineers test and compensate for latency issues in real-time

What is SoundSpeedGun?

SoundSpeedGun is a free, open-source application for macOS that is designed to measure audio latency from a microphone input. It functions by playing a short sine wave tone out through the selected audio output device and simultaneously recording from the selected input device. It then analyzes the recorded audio to detect when the played tone arrives back at the input. The time difference between playing the tone and detecting it back at the input is reported as the round-trip latency.

This can be very useful information for audio engineers and musicians working to minimize monitoring latency when tracking and recording. The lower the overall latency, the easier it is to perform when monitoring through software audio plugins and interfaces. Values above 10-15ms can start to feel laggy or delayed.

Some key features of SoundSpeedGun include:

• Simple single-window interface with clear input/output device selection and latency measurement display
• Support for measuring latency through various audio interfaces, from built-in laptop inputs/outputs to USB/Thunderbolt interfaces
• Additional reporting of sample rate and buffer size values from the audio interface driver
• Save/load configuration presets to quickly switch between different audio hardware combinations
• Free and open-source so users can inspect and customize as needed

If you do any sort of computer-based audio recording or monitoring, SoundSpeedGun is a handy utility for understanding and optimizing system latency. Just install, select input/output devices, and click Start to get precise microphone round-trip latency readings.
