O iCalvinus é o sistema oficial da Igreja Presbiteriana do Brasil e atualmente é composto por 4 módulos, a saber iCalvinus, iCalvinus Sínodo, iCalvinus Presbitério e iCalvinus Igreja. Seu objetivo principal é automatizar, e com isso agilizar, as reuniões da Comissão Executiva e Supremo Concílio da IPB. Desde 2010, quando iniciamos o uso, as reuniões estão armazenadas e disponíveis para consulta de documentos, resoluções e atas. O aplicativo iCalvinus também conta com preciosas ferramentas como o Digesto Presbiteriano onde é possível buscar diversas resoluções da IPB, o Anuário da IPB que disponibiliza dados cadastrais de Igrejas, Pastores, Concílios e Órgãos, Bíblia, Hinário e também as novas funcionalidades visando ainda mais agilidade durante as reuniões da CE e SC através da comunicação direta com os membros e facilidade nos processos de presença e votação ao longo das reuniões. As totalizações e os dados apresentados no iCalvinus são baseados nos dados cadastrados e obtidos pela SE-SC/IPB.

About

Auralize

Features
Read full description

Auralize is an acoustic measurement tool for iPhone that combines sound level meter and decibel meter features to measure, record, and document sound levels in the field. Built by acoustic and computer engineers, Auralize uses a calibration correction factor obtained in a laboratory. Up to 4000 Hz, the app qualifies as a Class 2 measurement, delivering reliable accuracy for technical fieldwork. Track sound levels in dB(A) in real time, view the equivalent level (Leq), the maximum level, and sound pressure (SPL) data with acoustic weighting. During measurement, follow sound variations on a chart updated in real time. More than measuring, Auralize helps you keep the full context of every measurement organized — from the field record to the final report. REAL-TIME MEASUREMENT Track sound levels in dB(A), the equivalent level (Leq), the maximum level, and sound pressure (SPL) information throughout the measurement. MEASUREMENT CHART See in real time how the sound level varies over the measurement and clearly follow how the environment behaves. AUDIO RECORDING Save the measurement together with a WAV-format audio recording, keeping a sound record of the analyzed moment. MEASUREMENT WITH CAMERA Perform acoustic measurements with photo and video, combining visual context with sound recording and real-time acoustic, location, and time data. PHOTOS AND LOCATION Add photos and location information to measurements, including coordinates and city, to record the context of every analysis carried out in the field. PROJECT ORGANIZATION Group your measurements into projects and keep an organized history to review past records and results whenever you need. PDF REPORTS Gather the data recorded during measurement into PDF reports ready to review and share. FROM MEASUREMENT TO REPORT Sound levels, charts, recordings, photos, location, and results stay organized in a single flow, making acoustic measurement work simpler and more complete. Measure. Record. Organize. Share. Terms of Use and Privacy Policy By using Auralize, you agree to the app's Terms of Use and Privacy Policy.
