NOAA Seeks Comments on Discontinuing WWV-WWVH North Atlantic and North Pacific Marine Storm Warnings
NOAA is once again considering ending North Atlantic and North Pacific Marine storm warning announcements at minutes 8, 9, and 10 of each hour on WWV, and minutes 48, 49, 50, and 51 of WWVH.
Submit questions, comments, or concerns about this proposed change with “NIST MARINE WARNING” in the subject line no later than February 23, 2018. NOAA had announced in April 2017 that it was considering this change but held off in the wake of supporting comments.
WWV and WWVH are services of the National Institute of Standards and Technology (NIST). — Thanks to Matt Deutch, N0RGT

WinAIRR
Программное обеспечение для измерения амплитудно-частотных характеристик звуковых систем.
Благодаря использованию специальных тестовых сигналов и их особой обработке приложение WinAIRR (Anechoic and In-Room Response for Windows) позволяет смоделировать акустически заглушённую безэховую камеру, результаты измерений в которой не нарушены посторонними шумами, паразитными отражениями и резонансами. Частоты дискретизации составляют от 8 до 44 кГц, длина сэмплов лежит в пределах от 64 до 16384 байт. В качестве опытных сигналов используются «дельта-импульсы» – импульсы малой длительности. В процессе обработки на принятой фонограмме выделяется временное окно свободное от отражений, а затем программа посредством быстрого преобразов
