    Hi all,
    So far, we know there is no tool for voice recording on pixi. Is it possible for us to do this? The answer is YES. I find a way to record voice from pixi's MIC. But you should install Terminal from Preware first. Now just type the following command in your Terminal:
    arecord -f cdr -t raw voice.raw
    Now the pixi [plus] is on recording mode. You can also minimize the Terminal to do something else. To stop recording, just active Terminal, type "Sym + c" which is known as "Ctrl + C" on a PC.
    OK, there should be a file in the current directory named "voice.raw". This voice file is a RAW format file with big-endian. We can not play it in our pixi [plus].
    To play it, please just follow these steps:

    Step 1, install optware via Preware if you didn't install it.

    Step 2, install lame. In the Terminal, type:
    ipkg-opt update
    ipkg-opt install lame
    Step 3, converting RAW file to MP3 file. In the Terminal, type:
    lame -r --big-endian voice.raw voice.mp3
    Once done, now you can see voice.mp3 in your current dirctory. Play it!

    I have wrote two shell script to do this easily.
    The "rec" script will record a voice file in RAW format and place it in /media/internal/rec/. The file name would be like "Sat_Jun__4_13-32-14_WST_2011.raw".
    If you have no rec directory in /media/internal, create it:
    mkdir /media/internal/rec
    The "lame" script will convert RAW to MP3.

    Normally, once we launch Terminal, the current directory is /var/home/root .
    So I copy the two script("rec" and "lame") to /var/home/root.
    I also create a symbol link m which targeting to /media/internal/rec:
    ln -s /media/internal/rec /var/home/root/m
    * How to use:
    To record a voice,
    sh rec
    To convert it to mp3 file, (for example)
    sh lame m/Sat_Jun__4_13-32-14_WST_2011.raw
    That all. G00d luck.

    # record voice via MIC into a file(RAW)
    DATETIME=`date | sed -e "s/\ /_/g" | sed -e "s/:/-/g"`
    cd /media/internal/rec/
    echo *Starting to record...
    echo *Recording to $DATETIME.raw
    echo **You may convert .raw file to .mp3/.ogg to play it:
    echo **#lame --big-endian -r $DATETIME.raw $DATETIME.mp3
    echo *To stop recording, press Sym+C
    echo *
    arecord -f cdr -t raw $DATETIME.raw || echo **Getting ERRORs!!! && echo . && exit 1
    # convert .raw to .mp3 audio format.
    echo *File to convert: $1
    if [ $# -gt 1 ]; then
    echo Only one file at a time...
    exit 1
    echo *Converting...
    lame -r --big-endian $1 `echo $1 | awk -F. '{print $1}'`.mp3 && du -ah `echo $1 | awk -F. '{print $1}'`.mp3 || Got ERRORs..
    exit 0

    Doesn't zcorder have pixi support?

    Yes, zcorder doesn't work on my pixi plus.
    There was no error to install and launch zcorder.
    But after I tapped the start record button, nothing happened.
    The timer just stayed at 00:00:00 and all buttons on the screen turned disabled.
    I closed zcorder and saw an empty file in /media/internal/recording/

    I think pixi's CPU is not fast enough to convert the stream to MP3 in real-time.

    So, the following command will not work on pixi:
    arecord -f cdr -t raw | lame -r --big-endian - voice.mp3
    But I can use "arecord" to record voice in WAV format.
    arecord -f cd out.wav

    During a call, press "Handfree" button would work.

    Thanks a lot! I had to use a different name for the conversion script because for some reason it was calling itself instead of the lame program. I just called it raw2mp3 instead of lame and deleted the lame file and it worked.

    If zcorder had an option to save in a lower mp3 bit rate it would work on the Pixi, right? If someone wants I can try to figure out what bit rate my Pixi can handle on the fly.

    Nice, works, too bad mic isnt that sensitive LOL! But I was wondering, how hard would it be to create a front end to these scripts for webos?

    I've tried the arecord -f cd out.wav method which works fine, but it just stops at 156 MB (about 15 minutes). Is there any way around this issue?
