If I get you right, what you want to do per sample point is strip the low byte and then XOR with 0X80. Try this with mere shell (recent bash) builtins:
Code:
hexdump -v -e '4/1 "0x%02X " "\n"' /tmp/sample.raw | while read _ LL _ RR; do printf "x%x x%x\n" $((LL^128)) $((RR^128)); done | while read LL RR; do printf "\\$LL\\$RR"; done

I'm trying to record audio using Audacity 2.0.5 installed from SlackBuilds. My system is 64-bit Slackware 14.1 and a sound card is Intel HD Audio. I didn't change my sound system to OSS.

Boy oh boy, with only a MONO mic input to use AudioScope gets much more difficult when the ALTDC board is included.
It needs, so far, two hits at the MIC input with a single hit at the HEADPHONE audio output.
The first at the highest practical resolution for the AC component and the second... (0 Replies)

rbash
RBASH(1) General Commands Manual RBASH(1)NAME
rbash - restricted bash, see bash(1)RESTRICTED SHELL
If bash is started with the name rbash, or the -r option is supplied at invocation, the shell becomes restricted. A restricted shell is
used to set up an environment more controlled than the standard shell. It behaves identically to bash with the exception that the follow-
ing are disallowed or not performed:
o changing directories with cd
o setting or unsetting the values of SHELL, PATH, ENV, or BASH_ENV
o specifying command names containing /
o specifying a filename containing a / as an argument to the . builtin command
o specifying a filename containing a slash as an argument to the -p option to the hash builtin command
o importing function definitions from the shell environment at startup
o parsing the value of SHELLOPTS from the shell environment at startup
o redirecting output using the >, >|, <>, >&, &>, and >> redirection operators
o using the exec builtin command to replace the shell with another command
o adding or deleting builtin commands with the -f and -d options to the enable builtin command
o using the enable builtin command to enable disabled shell builtins
o specifying the -p option to the command builtin command
o turning off restricted mode with set +r or set +o restricted.
These restrictions are enforced after any startup files are read.
When a command that is found to be a shell script is executed, rbash turns off any restrictions in the shell spawned to execute the script.
