More beautiful noise..... I really like noise This is A/C hum from the 240v (plus or minus) standard line voltage here (using an "unplugged Arduino UNO" as my "antenna"):
I've always liked noise on scopes and analyzers.... it's kinda hypnotic ....
Have you noticed how much more beautiful noise is, compared to a "clean" 1 KHz reference signal?
I was wondering is there something out there for Solaris 7 for screen capture?
Also it would really help if there was some software out there that can record whats happens on the screen for like 10 seconds or how ever long I need it to.
I did a search but doesn't seem to be alot out there. (10 Replies)
We are using Solaris 10 for our Radiation Treatment Planning and need to create a simulation for our service engineers. I need a screen capture tool that can not only capture screens, but create movies of mouse movements (similar to Captivate). I have contacted Oracle and talked to several people... (2 Replies)

It will capture an audio recording of any time length within the limits of OSX's QuickTime Player's capablility...
A shell script derivative of this will be used as a further capture for CygWin's AudioScope.sh.

Hello everyone!

Sadly, I have turned off my access to the Apple Developers Beta program after installing macOS 10.15 Catalina a few days ago.
After the install, I rebooted by MacBook Air and it "hard froze" and we were heading out of town so I grabbed a backup MBA running Mojave.
Then, after getting back at... (10 Replies)
Just a quick note for macOS users.
I just installed (and removed) Parallels Desktop 15 Edition on my MacPro (2013) with 64GB memory and 12-cores, which is running the latest version of macOS Catalina as of this post. The reason for this install was to test some RIGOL test gear software which... (6 Replies)
Currently have two ESP8266 modules testing some Blynk apps, whereI'm not so happy with the Blynk business model for developers, but that's another story.
So, with two of my ESP8266s currently "busy", I decided to work on the ESP32, and in particular the ESPWROOM32.

audio2tape - Sinclair ZX Spectrum audio to tape file converter
SYNOPSIS
audio2tape [-t type] [-s] [-r] [-k] [-z level] [-c level] infile outfile
DESCRIPTION
audio2tape converts audio files to ZX Spectrum tape images.
OPTIONS -t type
causes type to be used as the level detection trigger. There are two triggers implemented; the simple trigger just uses a threshold
value to convert to a one or zero on output, and the schmitt trigger implements a Schmitt trigger which outputs a less noisy signal,
but requires a stronger signal to noise ratio than the simple trigger. The default trigger is "schmitt".
-s causes the display of a frequency graph showing the sound levels present in the audio file. This can be useful when selecting good
crossover points.
-r causes any ROM blocks that are recognised to use idealised timing figures rather than the exact ones found in the audio file.
-k causes the tape file that is produced to keep any audio data from the original audio file that isn't recognised. This will allow
unsupported loading schemes, encryption tones etc. to be preserved in the file that is produced.
-z level
causes level to be used as the zero point in the supplied audio file, it allows adjustment for a DC offset in the audio file. The
default level is 127 from a range of 0-255.
-c level
causes level to be used as the Schmitt trigger noise threshold, this reduces the sensitivity to noise in the provided file. The
default level is 8 from a range of 0-127.
infile specifies the audio file to be converted. This file can be in any of the tape formats supported by libaudiofile.
outfile
specifies the output tape file. The format will be determined by the file extension and can be in any of the formats libspectrum(3)
supports for output.
BUGS
None known.
