Default Audio in Video recording

Hello guys.
Watching some new video recorded by gs2, i've seen that audio sampling rate is 16khz!!!!! I don't understand this choise by samsung (in every its phone, make very good video with poor audio!!!). Many years ago, nokia devices captured audio at better quality!So, now gs2 recordes fantastic 1080p video with high bitrate e framerate, but why use a poor audio?16khz can be good in common situation, but you'll never record a video with this audio quality (an old n95)
http://www.youtube.com/watch?v=-m0hkE1e2Z8

In first gs2 videos that I watched, sampling rate was 44100hz, why now 16000hz?
Can be solved in future, by modding?

thanks

It's not quite 44000khz but this is what VLC is telling me for the clips I've recorded on the highest settings.

16khz is BAD if you want record sound as in a concert!

So, can you try an alternative way, using RecorderNow and set media_profiles.xml (need root), on which set 44100hz for 1080p videos in encoder profile high?



Similar to this:
<MediaSettings>
<!-- Each camcorder profile defines a set of predefined configuration parameters -->
<CamcorderProfiles>

<EncoderProfile quality="high" fileFormat="mp4" duration="30">
<Video codec="h264"
bitRate="18000000"
width="1920"
height="1080"
frameRate="30" />

<Audio codec="aac"
bitRate="128000"
sampleRate="44100"
channels="2" />
</EncoderProfile>

<EncoderProfile quality="low" fileFormat="3gp" duration="30">
<Video codec="h264"
bitRate="384000"
width="176"
height="144"
frameRate="30" />

<Audio codec="amrnb"
bitRate="12200"
sampleRate="8000"
channels="1" />

</EncoderProfile>

<ImageEncoding quality="100" />
<ImageEncoding quality="100" />
<ImageEncoding quality="100" />
<ImageDecoding memCap="20000000" />

IN recordnow choose "high quality"

SO, if you want change only samplerate to 44100 in EncoderProfile quality="high"

Hi guys, so, is there any way to enable stereo recordi at high sampling rate during video recording?
The lack of digital zoom plus this strange audio limitation, let me to think that the sgs2 is not so powerfull as they want to tell us, what do you think about?
