IEC 60268-16 rev. 5
Download verification test signals
IEC 60268-16 rev. 5 describes test signals in Annexes A and C that are intended to be used to verify STIPA implementations. Those test signals are provided here.
If you are implementing STIPA in software or firmware, we recommend that you closely study the standard (including Annexes A and C) and take guidance on verification requirements that are given there. A summary of the test signals, and how these are to be used, are given in the document that can be downloaded below:
Verification test signals
The test signals for each of the verification tests can be downloaded here.
- Annex A 2.2 weighting factor tests
- Annex A 3.1.2 filter bank tests
- Annex C 3.2 direct method modulation depth tests
- Annex C 3.3 indirect method modulation depth tests
- Annex C 4.2 filter bank slope tests
All of the above verification test signals were developed by Embedded Acoustics and may be used for commercial and non-commercial use free of charge.
Note that the above signals are NOT intended for doing STIPA tests. These signals are intended only to verify that a STIPA implementation complies exactly with the requirements of the standard.
Looking for a STIPA test signal?
If you need a STIPA test signal, please consider that all STIPA signals offered by manufacturers of measuring instruments are copyrighted by their respective developers. If you require a STIPA (or full STI) signal for your own STI implementation, you have the option to develop your own signal or license an existing signal.
Bedrock Audio allows free download of (copyrighted and watermarked) STIPA and Full STI signals from their site:
Bedrock allows unrestricted non-commercial use of their signals, but a paid license is required if you intend to redistribute or promote the signal for use with your own STIPA implementation.
