NACAT5® — Nielsen Audio Code Analysis Tool — The Nielsen Company has developed NACAT, a Microsoft® Windows 10/11 operating system (64-bit) PC tool to aid in diagnosing audio watermarks embedded in an audio stream.
NACAT is a Graphical User Interface (GUI) application that captures audio, extracts Nielsen codes from that audio, then decodes and reports the extracted audio codes. The Nielsen EVS department uses the NACAT application for monitoring, assisting in troubleshooting, and verifying NAVE encoder installations.
This release has significant enhancements.
This version incorporates Decoder SDK v6.1.19, which includes the 2027 Rollover Fix (Does not apply to Radio Encoders). Key improvements include a Fix for InfoSid codes detection, the addition of a new "Depth" column in logs for N2 and N6 codes, and technical resolutions for the "Time String" column and "Raw Codes" decoding issues.
Enhancements continue to allow for the simultaneous decoding, display, and logging of both left and right channels for comprehensive monitoring, with the capability to decode all 6 channels.
Technical Requirement: The Windows PC must have at least one actively enabled audio input device for NACAT to open properly. Once launched, users can select their preferred audio input, including "loopback". If all audio input devices are disabled or missing, the application will fail to launch and may appear hung. NACAT 5 for Radio requires the use of a code mapping file (SIDMAP). To request a SIDMAP file containing the mapping for your station or station groups, please email encoding@nielsen.com. You will need to provide a list of station call letters or station ownership for the codes requested.
