Not an upload but this is a taster for what is to come.

The spectrum analyser is completed and nothing like the primitive free version previously uploaded here.

The images start with a voice capture using SOX and displayed at 5mS/Division, Note the red CAPTURE mode inside the top little window. In the COMMAND window the command SPECAN is ready to be entered.

Once entered the next image prompts for an External source for measurement input, for example the external microphone. 'N' will be entered and a 48000 byte main capture raw file is converted to an 8000 byte version for the limited 4KHz resolution of this code. I will try and extend to at least 24KHz resolution at a later date.

After a few seconds the spectrum displays this low resolution capture. This will automatically switch from main red CAPTURE mode to green STORAGE mode for the last image to write protect the current main capture. This display awaits an ENTER to return to the STORAGE screen of the original capture.

AudioScope...

Boy oh boy, with only a MONO mic input to use AudioScope gets much more difficult when the ALTDC board is included. It needs, so far, two hits at the MIC input with a single hit at the HEADPHONE audio output. The first at the highest practical resolution for the AC component and the second... (0 Replies)

MAC_TEST(4)						   BSD Kernel Interfaces Manual 					       MAC_TEST(4)

NAME
mac_test -- MAC framework testing policy SYNOPSIS
To compile the testing policy into your kernel, place the following lines in your kernel configuration file: options MAC options MAC_TEST Alternately, to load the testing module at boot time, place the following line in your kernel configuration file: options MAC and in loader.conf(5): mac_test_load="YES" DESCRIPTION
The mac_test policy module implements a testing facility for the MAC framework. Among other things, mac_test will try to catch corrupt labels the system is attempting to destroy and drop to the debugger. Additionally, a set of statistics regarding the number of times various MAC framework entry points have been called is stored in the security.mac.test sysctl(8) tree. Label Format No labels are defined for mac_test. SEE ALSO
mac(4), mac_biba(4), mac_bsdextended(4), mac_ifoff(4), mac_lomac(4), mac_mls(4), mac_none(4), mac_partition(4), mac_portacl(4), mac_seeotheruids(4), mac(9) HISTORY
The mac_test policy module first appeared in FreeBSD 5.0 and was developed by the TrustedBSD Project. AUTHORS
This software was contributed to the FreeBSD Project by Network Associates Labs, the Security Research Division of Network Associates Inc. under DARPA/SPAWAR contract N66001-01-C-8035 (``CBOSS''), as part of the DARPA CHATS research program. BUGS
See mac(9) concerning appropriateness for production use. The TrustedBSD MAC Framework is considered experimental in FreeBSD. While the MAC Framework design is intended to support the containment of the root user, not all attack channels are currently protected by entry point checks. As such, MAC Framework policies should not be relied on, in isolation, to protect against a malicious privileged user. BSD
