About

MuseumPlus Scan

Read full description

The MuseumPlus Scan App is an innovative extension of the robust MuseumPlus Collections Management platform, specifically designed to enhance and simplify the location management of museum collections. By leveraging the integrated barcode functionalities within MuseumPlus, this app significantly expands the range of options available to museum professionals, offering an unprecedented level of flexibility in their work. With the app's barcode and QR-code functionalities, users can easily track the precise location of every item in the collection, ensuring that no piece is ever misplaced or forgotten. This functionality is particularly valuable for large institutions with extensive collections spread across multiple storage facilities or exhibition spaces. By scanning barcodes, museum professionals can instantly update the inventory status of each item, reducing the likelihood of errors and ensuring that records are always up to date. The app simplifies the process of location changes, which can often be a complex and time-consuming task. Whether moving objects within the same building or transporting them to an entirely different location, the MuseumPlus Scan App makes it easy to track these movements. By scanning an object’s barcode, users can quickly record its packed or unpacked status, providing a clear record of its handling history. The app also supports audits and spot or condition checks, all vital processes in maintaining the integrity of a museum’s collection. One of the standout features of MuseumPlus Scan is its ability to function both online and offline. This is particularly advantageous for users who may need to work in remote locations or areas with unreliable internet access. Whether in the field, in a storage facility, or deep within the museum’s archives, users can continue to perform all necessary tasks without interruption. The app will synchronize with MuseumPlus once an internet connection is reestablished, ensuring that all actions are properly recorded and updated.

Read full description

An application for recording audio with real-time noise level monitoring and calendar-based organisation. Created for anyone with noise nuisance issues who needs to keep a noise diary. Features: - Audio Recording with Format Selection: Choose between AAC, WAV, and M4A audio formats. Real-time audio recording is handled with microphone permission, and high-quality audio capture is achieved at a 44.1kHz sample rate. (Note: MP3 is not supported; AAC provides better quality at the same file size.) - Noise Level Meter: Visualise real-time audio amplitude with a noise meter displaying a decibel-like scale (0-120 dB). Colour-coded visualisation (green to red based on volume) and animated waves that respond to audio input enhance the experience. Level descriptions include Very Quiet, Quiet, Moderate, Loud, Very Loud, and Extremely Loud. - File Management: Automatic saving with date and time stamps ensures recordings are saved in the app documents directory. Organised recordings are stored with metadata using SQLite, and recording duration tracking and maximum amplitude tracking for each recording are available. - Notes Functionality: Add notes to recordings during or after recording, and edit notes at any time. Include start and end times, a description of the noise and how it affects you. Notes are stored with recording metadata. - Calendar View: An interactive calendar displays days with recordings, allowing you to tap any date to view recordings from that day. Visual indicators for dates with recordings and an organised monthly view with easy navigation enhance the calendar experience. - Audio Playback: Built-in audio playback for each recording includes a progress bar with a time display, play/pause controls, and seek functionality. - Sharing Capabilities: Share recordings and PDF diary via email, messaging, or any installed sharing app. Export recordings to cloud services like Dropbox or Google Drive, and share with notes included as text. - Additional Features: Delete recordings with confirmation, display recording duration, and add format labels on each recording.
