Here you go, but please note the lines with MONITOR$= have been split
over 2 lines, as is the line after the if condition. All the changes
just ensure the sound channel to be recorded is found successfully.
#!/bin/bash
# pa-record
OUT="$1"
if [ -z "$OUT" ]; then
echo "Usage: $0 output-file" >&2
exit 1
fi
rm -f "$OUT"
EXT=${OUT##*.}
# Get sink monitor:
# MONITOR=$(pactl list | grep -A1 '^\*\*\* Source #' | grep
'^Name:.*\.monitor$' | cut -d" " -f2 | tail -n1)
MONITOR=$(pactl list | grep -A4 'Source #' | grep 'Name:.*\.monitor$' |
cut -d" " -f2 | tail -n1)
echo recording from $MONITOR
# Record it raw, and convert to a wav or ogg
echo "Recording to $OUT ..."
echo "Close this window to stop"
if [ "$EXT" == "ogg" ]; then
parec --format=s16le -d "$MONITOR" | oggenc --raw --quiet
--quality=4 -o "$OUT" -
else
parec -d "$MONITOR" | sox -t raw -r 44k -sLb 16 -c 2 - "$OUT"
fi
