Happy Holidays, everyone!

Here is my Holiday gift: A method for recording calls from the device!

note: it will require command line tinkering.

I got the idea and most of the information thanks to the blog link which dalonso posted here.

First you will need to get the pulseaudio-utils package either from here , or you can enable the tools repository and run

Code:

apt-get install pulseaudio-utils

there is a link to a single-click install file to add the tools repo here .

The pulseaudio-utils package provides two apps which I use in the scripts: 'parec' to record raw audio streams, and 'pacat' to play back raw audio streams.

The streams involved are: 'sink.hw0.monitor' for incoming sounds and 'source.hw0' for outgoing sounds when using the phone handset, and 'sink.hw1.monitor' for incoming and 'source.hw0' for outgoing when using a bluetooth headset.

In my home directory I created a few simple scripts for recording

for recording while using the handset, I have a script 'simpleRec.sh':

Code:

NOW=`date +%F-%H-%M-%S` 
echo $NOW > simpleDateTime
parec -d "sink.hw0.monitor" > MyDocs/tmp/$NOW.pulse.in.raw &
parec -d "source.hw0" > MyDocs/tmp/$NOW.pulse.out.raw

for recording while using bluetooth, I have a script 'simpleBtRec.sh':

Code:

NOW=`date +%F-%H-%M-%S` 
echo $NOW > simpleDateTime
parec -d "sink.hw1.monitor" > MyDocs/tmp/$NOW.pulse.in.raw &
parec -d "source.hw1" > MyDocs/tmp/$NOW.pulse.out.raw

To play back the most recent recorded call 'simpleLastPlay.sh' :

Code:

LAST=`cat simpleDateTime`
pacat MyDocs/tmp/$LAST.pulse.in.raw &
pacat -v MyDocs/tmp/$LAST.pulse.out.raw

To play back an older call using a unique date or time 'simplePlay.sh' :

Code:

pacat MyDocs/tmp/*$1*pulse.in.raw &
pacat -v MyDocs/tmp/*$1*pulse.out.raw

for example if you know you recorded a call on Dec 1 at 12:00 am, you could run ' ./simplePlay.sh 12-01-00-00 ' or any part of the date or time that you can remember, as long as it is unique.

To stop recording or playback just press ctrl+c.

Another script I made to stop any recording or playback if you can't get back to its original terminal window 'simpleStop.sh' :

Code:

killall parec
killall pacat

Final note: Please use it only where it is legal to do so, and please do not use it for any nefarious purpose. Enjoy!

The process is still new and under constant refinement. Acceleration suggestions welcome.

EDIT: ah, you were probably referring to the server response issues. Progress being made there, too.

iKneaDough, Thank you very much for the scripts!

Someone knows how this raw sound file can be converted to a known type, like wav or ogg?

Ive used this on my N82 as it is the best app on my old phone. So good for recalling back what someone has said.

Email the developer (support@fingertip-access.com) and ask for it, I know I have.

The main reason why I'm not changing my N95 is precisely the fact that I have a very good call recording app on it (Total Recall from Killer mobile). Until the n900 gets one, I won't change my phone.

I would like to buy either a n900 or a nexus one. Depending on which one gets a call recorder first.

Well.. now that the underlying hard work is done.. shouldn't be too hard to wrap those scripts into a deb file and create shortcuts/menu.desktop items for them.

All that's really left is for a UI designer to create a good looking UI for people and a deb build to put it all together. Being that you can see the actual commands being used in the scripts (obviously) - then it can be directly coded into a QT app with system calls.

For recording, you can do:
