Applescript application call problem...
Hi all...

I am trying to create a shell project purely for this Macbook Pro.
I do NOT want to use SOX as the sampling _source_ but Quicktime
instead, the idea being that NO third party installs will be needed.

The code below works fine except the commented out Applescript line
does not do what it says on the tin...

I want to sample 1 second snatches of a signal without the small audio
recording image appearing on screen. In other words a pseudo-embedded
mode...

Does anyone know if or how this can be done?
If not then I can live with it during each snatch...

Ignore the lines below the asterisks they are for my test purposes only
and be aware of wordwrapping...

Any help would be greatly appreciated...

TIA.
Code:
#!/bin/bash
# qt.sh
cd /Users/barrywalker/Desktop/Audio
rm *.aifc >/dev/null 2>&1
sample()
{
osascript << APPLESCRIPT
	tell application "QuickTime Player"
		# set visible of process "QuickTime Player" to false
		set sample to (new audio recording)
		tell sample
			delay 1.5
			start
			delay 1.5
			stop
		end tell
		quit
	end tell
APPLESCRIPT
wait
}
sample
# *********************************************************
afconvert -f 'WAVE' -c 1 -d UI8@8000 "/Users/barrywalker/Desktop/Audio/Audio Recording.aifc" waveform.wav
ls -l waveform.wav
afplay -d waveform.wav
dd if=waveform.wav of=waveform.raw skip=4096 bs=1 count=8000

aurecord

AURECORD(1)						      General Commands Manual						       AURECORD(1)

NAME

       aurecord - record a sound file from a Network Audio System server

SYNOPSIS

       aurecord [-audio servername] [-file format] [-data format] [-rate sample rate] [-mode input mode] [-gain input gain] [-time seconds] [-com-
       ment comment] [-?] filename

DESCRIPTION

       The aurecord program can be used to record audio data from a Network Audio System server into a file.  The recording  will  continue  until
       either the specified time has elapsed or aurecord receives a SIGINT or SIGTERM signal.

OPTIONS

       The following options may be used with the aurecord program:

       -audio servername
	       The Network Audio System server from which the file should be recorded.

       -file format
	       The file format to be used for the recorded audio data.	The -? option will display a list of valid file formats.  The default file
	       format is Sun/NeXT.

       -data format
	       The data format to be used for the recorded audio data.	The -? option will display a list of valid data formats.  Note	that  each
	       file format may only support selected data formats.  The default data format is 8-bit uLAW.

       -rate sample rate
	       The sampling rate (in hertz) for the recording.	The default rate is 8000 Hz.

       -mode input mode
	       Some  Network Audio System servers may have different input amplification modes for microphone input versus line level input.  This
	       option allows the amplification mode to be specified.  The two modes available are "mic" for microphone input and "line"  for  line
	       level input.  The default mode is "mic".

       -gain input gain
	       The input gain level in percent.  The default is 75%.

       -time seconds
	       The  time,  in  seconds,  for  the recording.  If this option is not used, aurecord will record until a SIGINT or SIGTERM signal is
	       received.

       -comment comment
	       A comment to be stored in the data file.

       -?      Displays a usage message and a list of supported file and data formats.
