Hi Paul
I think I will try this one thing. Let me reinstall the tinyos tool set and
source tree so that I get the original settings for ADC and Mic details and
the compare because it might be some change that I have made that is making
it behave in this way. Because I do remember making some change
Hi Paul
Thanks a lot. I really appreciate your help. I actually thought of that and
had emailed Mr. Siquan a long time back and would do it again, but I have
not heard back.
Also, even if the sound source is a continuous sound source still the
samples dont respond.
I was thinking of the left adju
Akankshu,
I have taken a look at the code, but I'm not really able to say what is
significantly different between the two other than the fact that
SoundLocalizer is designed to sample the microphone as fast as possible,
so there are probably some optimizations that Hu Siquan (the author of

Hi Paul
Can you tell me what might be the different between the microphone
implementation in MicrophoneC inside SoundLocalizer Vs the MicP inside
mts300 ?
Thanks a lot

Hi all,
sorry for interfering this thread. But, where can I find the

Hi Michael and Zainul
Thanks a lot for your response. I am grateful to be hearing from you.
I will look into the corrected mean solution before I suggest some hardware
changes to my team.
Although, my bigger question was why direct sampling by calling

I suspect that the straight averaging thing is not what you want.
I haven't looked at the mic data, but it's sampling an AC
signal (sound wave pressure alternates between compression
and rarefaction at the frequency you perceive) and is probably
biased so a no-pressure signal is pretty much in the

Hi All
I am using two mechanisms for high sampling.
1. Using MicStreamC and changing the prescalar value inside MicP to
ATM128_ADC_PRESCALE_32 and the gain value is set to 64.
I create a buffer of 1000 samples and every time the buffer gets full I take
the average and print it out. The problem is t
