Ravan Mac OS
Install and add feeds
Raven Reader for Mac is a free RSS software with access to multiple platforms and is built with modern technologies using Electron and is available for Windows, macOS and GNU / Linux platforms.
After installing the software, you need to add a new stream, which you can bookmark as a favorite, and see its updates in a separate list. Raven Reader for Mac can also display updates from all your feeds simultaneously.
With Raven Reader for Mac you can import your subscriptions directly, as well as export them when you move to another RSS application.
A simple interface that includes many viewing modes
The Raven Reader for Mac interface has a minimalist and clean design and is not crowded with buttons and toolbars. It also uses a three-panel design. On the left a side window listing RSS feeds and filtering options.
In the middle we will find the List of articles, which will show the title of the article, the name of the site, the date of publication and a favicon of the site to make it easier to locate. And on the right is the content area, where a plain text version of each article is presented.
In conclusion
Raven Reader for Mac removes things that might bother you while reading, such as ads, banners. The software provides easy settings with which you can further optimize your desktop news reader experience.
If you are looking for a simple application that can help you keep track of your favorite articles, Raven Reader for Mac is definitely a great choice.
The Ravan Samhita is an astrological text or scripture narrated by Shiva and written by Ravana. Medicine The Ravanakumara Tantra is a part of the tantric rituals of the Kriyakalagunottara Tantra, 43 and it is an 11th-century Sanskrit work for the treatment of children's diseases. Raven for Mac starts up quickly. Its default window size is good, keeping large areas of the screen visible, but allowing for access to all major buttons.
Raven Pro is a software program for the acquisition, visualization, measurement, and analysis of sounds. Raven Pro provides a powerful, user-friendly research and teaching tool for scientists working with acoustic signals. Raven Pro’s highly configurable views provide unparalleled flexibility in data display.
View any combination of waveform, spectrogram, spectrogram slice (single spectral frame), or selection (average) spectrum views.
Independent control of spectral window size and DFT size enables improved frequency measurement precision. Specify spectral window size by sample points, time units, or corresponding bandwidth. Choose DFT size directly or by corresponding frequency measurement precision. Variable overlap between spectral frames. Choice of six spectral window functions.
Raven’s powerful view linkage controls enable you to simultaneously view a signal at multiple time or frequency scales or at different spectral analysis resolutions. Link time and frequency scales so signals in different windows zoom and rescale together, facilitating visual comparisons between recordings.
Multi-line wraparound spectrogram views let you look at longer time periods while preserving a fine temporal viewing scale.
A workspace saves all information about Raven's state, including what signals are open, the size and placement of their windows, what views exist for each signal, selections in each signal, and linkages among views within and between signals. You can later retrieve a workspace to continue your work exactly where you left off.
Presets let you easily switch among frequently used configurations without having to specify numerous parameters for window layouts, color schemes, measurement sets, spectrograms, recorders, band filters, selection labels, and detectors.
A color scheme consists of a spectrogram colormap relating power values to display colors, and color specifications for elements within each view (such as selections, axes, backgrounds, title text, etc.). Choose from eight predefined colormaps, and edit the color for each element in a view.
Paged sound windows enable fast and easy navigation and viewing of recordings of any length, consisting of any number of sound files (for example, a full year of continuous recording in 1-hour sound files).
Visually review long recordings (for example to search for specific sounds of interest) many times faster than real-time speed.
Open sound files saved in WAV, AIF, MP3, and FLAC formats.
Open sound files with any number of audio channels. Open all channels or a specified subset of channels.
Export images of signal views or sound windows via a variety of graphics file formats, or via the system clipboard for easy import into word-processing, presentation, and graphics programs.
More than 70 measurements are available for rectangular time-frequency selections around signals of interest. Selections can be created manually by drawing boxes on spectrograms or other views, or by Raven’s band-limited energy detector (see below). Selections measurements are shown in rows in a spreadsheet-like selection table. In addition to measurements computed from the audio signal, selection tables can include multiple user-defined annotations.
Selection tables can be saved as text files for easy import into statistics, spreadsheet, or other programs
Raven’s spectrogram correlation tool provides a quantitative measure of similarity between two sounds. Batch correlation generates a square correlation matrix containing similarity measures for all possible pairs of input sounds. Correlation matrices can be exported for use in in other programs, for example in cluster analysis or comparisons to other types of data.
Raven’s Band-Limited Energy Detector (BLED) can rapidly scan recordings to automatically create selections around events of specified durations in a user-defined frequency band that exceed the background noise level by an adjustable threshold. The BLED can be run in an interactive mode for fine-tuning detection parameters, and in a batch mode on large numbers of files. Measurements are immediately available for selections created by the detector.
Raven’s Selection Review interface accelerates review of large numbers of selection generated by an automated detector by displaying a matrix of thumbnail images of selections. Multiple selections can then be annotated with a single keystroke, for example to label true versus false detections or to assign call type or species labels.
Compare the results of a detector run against a “truth” table created by a human. Raven automatically labels true positive events (TP) that the detector found, false positives (FP), and the false negatives (FN) that the detector missed. This feature facilitates quantitative assessment of detector performance.
Raven Pro supports audio data acquisition using the computer’s built-in sound card, NI-DAQ (National Instruments Data Acquisition hardware), or ASIO (Audio Stream In/Out) audio input devices. NI-DAQ devices provide input capabilities of up to 32 channels with an adjustable voltage range, and ASIO devices provide 24-bit audio sample size capabilities.
Raven displays waveform, spectrogram, and spectrogram slice views in real time during data acquisition.
