Ravan Mac OS
IMPORTANT 1: see section 'Mac OS X Server' (below) if installing on Mac OS X Tiger Server version 10.4.6 or later 10.4.x version.
Feb 02, 2018 Set the RAVEN as the display furthest to the left for best performance. SYSTEM PREFERENCES Set Main Display: Navigate to System Preferences and in “Display” settings drag the menu bar to the RAVEN to make it the Main display. This is required for the RAVEN tool-bars to appear on the correct displays. Raven Curse is a visual novel with a few simple adventure elements and several endings, one of which is considered the “true ending”. Since the game is a prequel of the books, it is not necessary to have read the books beforehand, and therefore offers the perfect introduction to the series!
Jump Raven ' s initial Macintosh release was a commercial success. Discussing the multimedia development scene in 1994, a writer for The New York Times called the game one of 'the best-selling and most critically praised multimedia titles on the market', alongside Myst.

IMPORTANT 2: If upgrading to Leopard/SnowLeopard also note that Leopard installs Apache 2.2.6 whilst Tiger comes with Apache 1.something so your Apache configuration and custom modules will need modification/recompiling.
1. Log in as administrator (aka admin) and install the Xcode tools if you haven't already got them installed on your system. This will give you all the stuff you need for writing code on your Mac.
You can pick the Xcode tools up from http://developer.apple.com/tools/download/ or install it from your distribution CD.
To install Xcode tools from the CD/DVD:
- Insert the CD labelled 'Mac OS X Xcode Tools' or the install DVD for Leopard and double-click on the XcodeTools.mpkg icon. For Leopard you need to double-click on 'Optional Installs', then 'Xcode Tools' to get to the XcodeTools.mpkg icon.
- Enter your administrator password.
- Follow the instructions in the installer.
To install the Xcode tools from the the package (i.e.. XcodeTools1.5_CD.dmg) that you downloaded from the developer.apple.com site:
- Double-click on the XcodeTools1.5_CD.dmg.
- Enter your administrator password.
- Follow the instructions in the installer.
2. Download a copy of mod_ucam_webauth from https://raven.cam.ac.uk/project/apache/files/ (and if necessary double click on mod_ucam_webauth-1.4.2.tar). (By default this will be downloaded into a folder called mod_ucam_webauth-1.4.2 on your desktop or if using Leopard all downloaded items will go into your Downloads folder.)
- Start the Terminal application.
- Type the command 'cd Desktop/mod_ucam_webauth-1.4.2' (or 'cd Downloads/mod_ucam_webauth-1.4.2' on Leopard/SnowLeopard).
- To build ucam_webauth on Tiger and SnowLeopard type the command 'make'.
You should see something along the following lines:
- On Leopard you unfortunately cannot use APXS as it does not appear to understand about fat modules and just running 'make' will result in a non-functional mod_ucam_webauth module. Thusly you need to type (best to cut and paste!) the following horror into your Terminal:
If the above two commands result in errors for you, what you need to do is to run 'make clean' then run 'make SUFFIX=la'. This should work without errors and produce some output that will contain two lines similar to the above two commands. What you need to do is to then run 'make clean' again and then copy and paste the first command then the second command as was displayed when you ran 'make SUFFIX=la' BUT you have to add the options '-arch ppc -arch ppc64 -arch i386 -arch x86_64' to each of the commands to cause the module to be built 4-way-fat as is needed for Leopard's Apache installation.
- Then copy the module into the /usr/libexec/httpd/ directory by typing 'sudo make install' on Tiger or 'sudo make SUFFIX=la install' on Leopard and SnowLeopard.
You should see something along the following lines:
3. Download the necessary RSA public keys from Raven_keys and place them in /usr/conf/webauth_keys/ on Tiger or /etc/apache2/webauth_keys/ on Leopard. For Leopard the easiest way to do this is to simply execute the following commands on the Terminal:
The Apache module only needs the 'PEM formated PKCS#1 RSA public key' which is stored in a file named pubkey<n> (currently pubkey2). The names of the key files should not be changed - beware that they have no filename suffix but that some browsers may add .txt or similar when downloading them.
4. For Tiger, add the following to /etc/httpd/httpd.conf, after the line that reads 'ClearModuleList':
For Leopard and SnowLeopard, add the following to /etc/apache2/httpd.conf, after the last line beginning with 'LoadModule':
This is the minimum configuration required to restrict access to resources in a particular directory to users with a Ucam-WebAuth login. See https://raven.cam.ac.uk/project/apache/README.Config for further customisation options.
Mac OS X Tiger Server
Note the below applies to Mac OS X Tiger Server. Mac OS X Leopard and SnowLeopard work fine without doing the below and in fact doing the below will break Raven.
By default Apache on Mac OS X Server uses Apple's own authentication module, mod_auth_apple, in place of the standard Apache module, mod_auth. In Mac OS X Server version 10.4.6 (and probably in future versions of Mac OS X Server 10.4) mod_auth_apple won't inter-work with mod_ucam_webauth.
To work around this, disable use of mod_auth_Apple and re-enable mod_auth (which Apple continue to supply). To do so, edit /etc/httpd/httdp.conf and replace
with
and
with
It may also be possible to make this change using the Apache management GUI - see Apple documentation for details.
Background to the problem
The standard Apache mod_auth supports authentication using user names andpasswords stored in files maintained by the htpassword utility. Apple'smod_auth_apple appears to extend this to allow users to authenticate eithervia credentials stored in htpassword files or via the system's login username/password database.
While mod_ucam_webauth replaces the password validation functions ofmod_auth and mod_auth_apple, it still relies on other functions that theyprovide. Even though mod_auth_apple largely replicates mod_auth'sfunctionality it unfortunately does so in a way that is incompatible withmod_ucam_webauth's needs.
As far as we know the only thing you lose by replacing mod_auth_apple withmod_auth is the integration with the system's login user name/passworddatabase. Obviously that's a problem if you need it, or if you are runningany web applications that rely on it. Otherwise this loss probably doesn't matter.
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.
Ravan Mac Os X
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.
