Hey hey again,
the next thing I'm looking for is a program to detect volume over a certain
threshold, which can print out a marker there. This function should - at best
- be able to ignore new peaks within a certain period of time, like a gate
with very long release times.
To elaborate the scenario: I'm recording myself sleeping, to a) find
involuntary actions and b) do quick narrations of dreams, should I wake up and
remember anything. So, I'd like to jump to the short moments of "action"
within the relative silence.
Any help is appreciated, thanks for staying with me.
Best wishes,
Jeanette

This is not exactly what you describe but it may meet your requirements:
http://plugin.org.uk/timemachine/
It's a GUI program, but the GUI is just one big button, which may or may
not have a keyboard binding.
The program has an auto-record feature based on the signal level. here's
the command line help:
Usage timemachine: [-h] [-i] [-c channels] [-n jack-name]
[-t buffer-length] [-p file prefix] [-f format]
[-a] [-b begin-threshold] [-e end-threshold] [-T end-time]
[port-name ...]
-h show this help
-i interactive mode (console instead of X11) also enabled
if DISPLAY is unset
-c specify number of recording channels
-n specify the JACK name timemachine will use
-t specify the pre-recording buffer length
-p specify the saved file prefix, may include path
-s use safer characters in filename (windows compatibility)
-f specify the saved file format
-a enable automatic sound-triggered recording
-b specify threshold above which automatic recording will begin
-e specify threshold below which automatic recording will end
-T specify silence length before automatic recording ends

Hi Chris,
that did look interesting, but I can't compile it, possibly the source
code is a little deprecated. Still thanks a lot, it would have done.

You could change the version and release, if required fix the
dependencies and simply replace the checksums with
"sha256sums=('SKIP')", but seemingly 0.3.3 is still the latest version.
Maybe libsndfile is part of the dependency chain, if not, who cares,
if you anyway have it installed.

On Debian/Ubuntu it's in the package archives as "timemachine".

When using the posted PKGBUILD, the compiling works on
[rocketmouse@archlinux tmp]$ uname -m
x86_64
and launching it works, too, but I didn't test if it does its job.

Hello,
There is also a nice Qt app also, QJackRcd which can record stereo
through Jack, and automagically pause or create a new file when the
audio reaches a certain threshold. This is useful for very long sessions
with moments of blank audio.
This is included in Debian, Ubuntu and Arch, but if you prefer build it
from scratch, the project is on sourceforge:
https://sourceforge.net/projects/qjackrcd/
Happy recording..

This should be doable with dtas-partstats, part of my very
incomplete and largely undocumented duct-tape audio suite:
http://dtas.80x24.org/
Basically, dtas-partstats runs the sox "stats" effect on 10s
intervals of a longer audio file and outputs the stats for each
interval to stdout. In the output, the 1st column is the time
interval, 2nd column is the combined peak of all channels.
It should not be difficult to code up something similar using
the "trim" and "stats" effects of sox in your favorite scripting
language if you don't have Ruby installed.
To elaborate the scenario: I'm recording myself
sleeping, to a) find
involuntary actions and b) do quick narrations of dreams, should I wake up
and remember anything. So, I'd like to jump to the short moments of
"action"
within the relative silence.
Anyways, I use partstats to find peaks in live recordings for
testing limiter, compressor and EQ effects to even out the
overall volume of the result. For live concerts, these peaks
are are common from audience noise, dropped/bumped equipment,
or room gain on drums.
It can also take advantage of multiple CPUs to process the 10s
partitions in parallel on systems with GNU nproc(1) or Ruby 2.2+
installed,

I tried to record myself sleeping in order to find out
what I was
uttering. In my case I recorded the entire night, an approach which you
should do as well, and then strip silent parts from the recording in an
extra step. This way you will not lose material in case your filter is
not configured optimally.
I must say that I was more in need of a snooring detector than any other
detectors though. ;)
SoX has two effects, silence and vad (voice activity detector) which can
possibly anaylze your recording.
One would have to put this inside a script that chops off segments of
your recording, and then repeats the same action with the remainder.
A research using ixquick gave the following as well:
https://github.com/amsehili/auditok
The aubio toolkit on Debian offers two binaries:
aubioquiet - a command line tool to extracts quiet and loud regions from a file
and
aubiocut - a command line tool to slice sound files at onset or beat timestamps
which sound promising as well.

Hey hey Peter,
that already is my approach, on the same grounds that you mention.

Ah, I expected that SoX would be thrown in at some
point. Well, I'll
look into Sox and the other tools you mentioned. Thank you.

Hi Jeanette, List,
I've done this with sox and a bash script.
The script records from default audio device only when there is a sound
to record (i.e. exceeding a THRESHOLD). Each file is encoded as flac (in
order to not consume much disk space for very long runs) and the file
name contains some info such as a timestamp, an RMS value, ans some
other statistics.
I wrote the script, but some parts are taken from varius guide I've
found on the net, so I've not the credits for the original author(s).
Here is the script
#!/bin/bash
FORMAT=".flac"
DEVICE="default"
THRESHOLD="5%"
TMPFILE=tmp$FORMAT
echo $TMPFILE
while true; do
sox -t alsa $DEVICE $TMPFILE silence 1 0.1 5% 1 1.0 5%
DATE=$(date +%Y%m%d%H%M%S)
LEN=$(sox $TMPFILE -n stat 2>&1 | sed -n 's#^Length
(seconds):[^0-9]*\([0-9.]*\)$#\1#p')
MAX=$(sox $TMPFILE -n stat 2>&1 | sed -n 's#^Maximum
amplitude:[^0-9]*\([0-9.]*\)$#\1#p')
RMS=$(sox $TMPFILE -n stat 2>&1 | sed -n 's#^RMS
amplitude:[^0-9]*\([0-9.]*\)$#\1#p')
FREQ=$(sox $TMPFILE -n stat 2>&1 | sed -n 's#^Rough
frequency:[^0-9]*\([0-9.]*\)$#\1#p')
mv $TMPFILE $DATE$FORMAT
echo "[$DATE] $LEN, $MAX, $RMS, $FREQ" >> record1.log
done
