I like the function idea for the config file. Why didn't I think of it...
As for the others, let me get the status lines cleaned up and if need be Trigger/Sync points first... Then I will experiment.
Thanks a lot matey...
Still working out how to get DC in on ONE input only...
I have a simple method of relay switching AC to DC and back using the 1KHz generator but even with the chopper I have no means, AFAIK, whether the DC is +ve or -ve.
This is the idea I have gotten, use the chopper to get the relative DC level, and on exactly the same multivib use the VFO section to detect whether the signal is +ve or -ve, a low freq being -ve and a high freq being +ve... FM and AM in 1 swoop... ;oD
Remember I have only ONE input...
The code should be easy...
BTW, tested on this Macbook Pro OSX 10.7.5 in DEMO and SOX modes and my Gnome Debian 6.0.x in DEMO and DSP modes...
The DRAW command now works immediately after a REAL scan...
(On the first run it defaults to OFF for slow machines.)
It can be turned off using the HOLD command...
The config file is now a function as Corona688 suggested.
The two images are the SOX sinewave generator auto-running from
the script with the earphone output connected to the mic input using the home
built hardware previously shown and the levels set using the output volume
and mic input controls.
The TBVAR set at 3 in and 3 jump for easy viewing, equvalent to 500uS/DIV,
proving the horizontal calibration is correct, 2 divisions per cycle...
Set to 1mS/DIV and you will see the calibrtaion is correct.
EDIT: Removed one small block, it does not affect the running but was a
copy and paste error on my part... Sorry.
Well in the last day or so this thread has been given 5 stars. To those following in AND who voted for it I say - Thank You. It was a wonderful surprise to come to with this next upload.
This upload now has all the deliberate slowing down "sleep 1" lines removed and placed into the correct positions and a general cleanup.
The start of the internal synchronisation code is started and an auto-save facility added.
This auto-save is _volatile_ so use with caution. By volatile I mean, when enabled it WILL save a copy of EVERY scan whether it is a capture or a replay.
It is easy to code for capture only but I decided to do every scan because it is easier to delete files than try to get them back again. The filemanes are _numeric_ using EPOCH values and saved to /tmp ATM...
The new commands are SAVEON, SAVEOFF, TIRG with unfinished subcommands of SYNCEQ, SYNCGT and SYNCLT. I am working on these in the evenings, UK local time and should be ready by the weekend.
Found 2 bugs and 1 programming error, yup there are bugs... ;oO
The bugs are esoteric but the error is stupidity on my part... ;oD
I suspect none have been found by yourselves who are trying this out however...
Removed the bash RANDOM call and used /dev/urandom instead. It is _infinitely_ quicker for the DEMO capture mode...
The first of the _internal_sync_ routines done.
Help file updated, etc, etc...
From Command mode:-
TRIG<CR>
SYNCEQ<CR>
Caps shift u or caps shift d to decide a sync point from 15 to 240. Then <CR>...
This starts the display from the value set.
Do all this again and the trace will start from another point with the value chosen...
If the value is not found then the trace runs from the start of the waveform.raw file at the FASTEST timebase speed...
Working on neagtive going SYNCLT and positive going SYNCGT ATM...
The code has now had extensive testing on an ACER Aspire One netbook using PCLinuxOS 2009 in DEMO and DSP modes also...
Before running delete your existing /default/full/path/to/AudioScope.config file so that the
changes can take place correctly... Also manually change the zero_offset value to give a centre straight line with 0 input voltage. It is now -2 on my Macbook Pro machine...
Well the positive going and negative going sync is done although IMHO they are not of much use.
The EXT trigger is on hold until a calibrated Y amp, at least AC coupled, is finished. A starter piece of home brew hardware is under construction.
I am now working on a low signal level ZOOM facility.
This is for signal levels that are actually inside 4 bits of depth instead of the quantised 4 bit depth used for the actual display of large signals inside the terminal window...
Also the simple Y amp and vertical calibration circuits to be added to the end of the script too.
Hi all...
Well I have not been inactive but working out how to make OSX 10.14.x command line audio player have a variable sample rate.
This is a back door as afplay does not have a sample rate flag unlike aplay for ALSA, in Linux flavours.
This is a DEMO only but a derivative of it will... (2 Replies)

Any help is highly appreciable.... (11 Replies)
This site is the first to get this snippet.
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.

Hi,
I am stuck while developing a shell sub-routine which checks the log file for "success" or "failure". The subroutine reads the log file and checks for key word "success", if found it set the variable (found=1). It returns success or failure based on this variable.
My problem is, I can... (2 Replies)
