Thread: Method about phone recording

    Default Method about phone recording

    Hi,
    I would like to have the phone call recording on desktop PC, SUSE or Windows 7. The present recording program can only record the sound frim microphone. Are there some free program can record both the mic and the speaker sound at the same time?

    Thanks.

    Hi
    If your using pulseaudio, it's pretty simple with parec and sox to dump
    it to a file.

    Hi
    And a script to do it all....

    Code:
    #!/bin/bash
    #
    # Based on script at http://www.outflux.net/blog/archives/2009/04/19/recording-from-pulseaudio/
    #
    
    # Set a date and time
    RECDATE=`date +\%m%d%y%H%M%S`
    
    # Output files
    SPK_FILE="rec_speaker_$RECDATE.flac"
    MIC_FILE="rec_microphone_$RECDATE.flac"
    
    # Get current pulseaudio sink
    PA_SINK=$(pactl list | grep -A2 '^Source #' | grep 'Name: .*\.monitor$' | awk '{print $NF}' | tail -n1)
    
    # Start recording speaker and microphone and save as wav files
    /usr/bin/parec -d "$PA_SINK" | /usr/bin/sox -t raw -r 44100 -b 16 -e signed -c 2 - "$SPK_FILE" &
    /usr/bin/parec -r | /usr/bin/sox -t raw -r 44100 -b 16 -e signed -c 2 - "$MIC_FILE" &
    
    # Add some feedback to user
    echo -e "\nRecording speaker output to $SPK_FILE ..."
    echo -e "Recording microphone input to $MIC_FILE ...\n"
    read -p "Press any key to halt recording ... " -n1
    
    # Kill off the processes
    kill -s SIGTERM `pidof -s /usr/bin/parec`
    kill -s SIGTERM `pidof -s /usr/bin/parec`

    i do not know, but i do know that in some areas of the world it is
    against the law to record someone else secretly..

    if that is the law where you live then you must be sure and _record_
    them saying it is ok to record the call..

    i'm not a lawyer--you should ask one to inform you of the local law.

    That is true in the UK in some circumstances but not in others.

    That is not generally true in the UK, although consent is necessary in
    some particular circumstances. See, for example,
    http://www.ofcom.org.uk/static/archi...qs/prvfaq3.htm

    In short, the law in this area is quite complex so you should check what
    applies in your own jurisdiction.

    He said it is true in some areas of the world, that UK has special
    laws does not matter, nobody knows where the OP lives.
    To give an example where it is explicitly forbidden always expect you
    have explicitly the consent from the caller is where I live (Germany),
    but of course that also does not matter as long as the OP does not live
    here.
    So as dd described it it was correct.

    The OP has of course to check the laws in the area where he/she lives
    (otherwise it can become quite expensive or worse).

    You misread my point. I did not and do not disagree with DD's first
    statement; I made no comment on it. I simply stated the position in the
    UK. So you are trying to draw conclusions from a false premise.

    My objection was to his second statement, which is wrong in general. And
    I used the UK position as an example, which is why I made my comment
    about the first statement. Of course, it is possible that it is true in
    some jurisdictions, such as Germany, which is why I made no general
    statement, but simply pointed out that it is important to check the
    local laws. DD was the one that made a general claim that was not valid.

    its probably not worth another post, but:

    Dave is right, the way i phrased my second point can be read to mean
    that i said in all locals the recording party must get an audio
    statement from the person being recorded agreeing to that..

    which of course, would be incorrect in some/many/most areas.

    so:

    - it was not my intent to pretend to know the law in all areas (i
    thought i made that clear)

    - certainly, in some areas the called individual can pre-authorize via
    (say) postal mail, or email, or or or . . .

    - i know in some jurisdictions that only one of the two parties has to
    agree to recording--and, that agreeing party can be the one making the
    recording (therefore the recording can be done secretly)..

    - i worked once in a job where recording was routine, and my employer
    required we record the verbal agreeing statement of the distant
    party....but, if that party said NO, we turned off the recording device
    and delayed the conversation until a live monitor could listen in on
    what transpired and would later attest to the content of the call, its
    conclusions and verbal contracts reached, by a signed memo for record..

    - i worked in other jobs where both sides of every call were recorded
    but the other party was not so informed, and was not legally required to
    be..

    - SO, (as said) the law is complicated and varies widely by country and
    political divisions within: so consult a lawyer in your area to learn
    the law (but, i already said that)

    - therefore: freerjw when someone finally gives you a technical answer
    to your question, remember that failure to follow the law in your area
    could prove to be costly.

    Point taken, I misinterpreted what you wrote.
