AudioScope is a text mode audio oscilloscope that captures sounds using DEMO, SOX, or DSP (/dev/dsp}. It is primarily a learning tool for kids. The script includes code and circuit diagrams for calibrating the horizontal and vertical axes. It features a demo mode with no dependences that samples /dev/urandom.
|Operating Systems||OSX 10.7+ Debian-based Linux PCLinuxOS 2009|
Release Notes: This release features the start of a proper manual inside the code along with another text mode circuit. Everything is saved to /tmp at the moment. It now has a progress bar on startup for slow machines but is now setup for the Apple Macbook Pro 13". SOX is auto-detected if installed. All relevant files are now generated and saved to /tmp and not commented out. The sinewave.wav file can be transferred to your phone via email for use as the signal source.
Release Notes: This version includes CygWin users and /dev/dsp. It is uploaded in CygWin guise and is marginally slower on real Unix-like machines, but all of the original code is commented out and not deleted. All you need to do is search for CYGWIN, comment out the relevant line(s) below it, and uncomment the single line above it. This changes the hex dumper from "od" back to the original "hexdump" again. Another simple circuit at the end for the DC control pulse under construction.
Release Notes: A semi-automatic Arduino detection command ARDDET
Release Notes: This release removes the "clear" command. The function "clrscn()" replaces it. It removes the "sleep" command. The function "delay()" replaces it, with keyboard override. These functions use builtins and terminal extensions only. This release adds a LOAD command to load a capture into the _buffer_ and display it. On program startup, a pseudo-capture file is generated as "0000000000.BIN" in the /tmp/ directory to test the LOAD command. If you enter a wrong filename, it does nothing except return you to the Scope's COMMAND window.
Release Notes: This is the first Freecode announcement.
