REM Generate a pure 1KHz sinewave using SOX...
REM $VER: SOX_DEMO.BAT_Version_0.00.10_(C)2013_B.Walker_G0LCU.
REM This script uses standard Notepad and a default Windows 32 bit install ONLY...
REM It requires no extra installs except SOX itself...
REM The 8 bytes of binary was also generated inside the default Windows OS to windows 7... ;o)
REM Create an 8 byte binary _string_ first for 1 complete sinewave cycle...
SET "rawfile=€&&€ÙþÙ"
REM Write the 8 bytes of binary data to disk in your default TEMP folder...
ECHO | SET /P="%rawfile%" > %TEMP%.\SINEWAVE.RAW
REM Append to the file in powers of 2 to 8*(2^13) = 65536 bytes...
FOR /L %%n IN (1,1,13) DO TYPE %TEMP%.\SINEWAVE.RAW >> %TEMP%.\SINEWAVE.RAW
REM The path is where a default install of SOX resides...
REM Now play the tone burst for around 8 to 9 seconds...
C:\PROGRA~1\SOX-14-4-1\SOX -b 8 -r 8000 -e unsigned-integer -c 1 %TEMP%.\SINEWAVE.RAW -d
REM 1KHz sinewave demo end...
REM ENjoy finding simple solutions to often very difficult problems...
