Terms

Effective 28 August 2026.

Pulse Check is free software provided as a timing-estimation aid. You may use and modify it under the MIT License.

Measurement limits

Browser audio timing is an estimate. Results can include display delay, touch sampling, operating-system scheduling, browser behavior, output routing, and human response. Do not treat an export as laboratory certification. Validate release-critical timing with physical loopback equipment and tests on each target device.

No warranty

The utility is provided “as is,” without warranty of any kind. You remain responsible for testing and for how you apply its suggested offsets.

Acceptable use

Use only audio you are authorized to process. Because processing stays local, Pulse Check does not receive or inspect your files.
