Down Convertion from 32Khz to 16Khz
hi
on my device i can sample only at 32khz and want to use speex at 16khz so i
need to down-convert the input signal by factor of 2.
does anyone provide me a reference to some code that does that? are there
any trick to do that?
i tried to add to subsequent sample but the result was very bad.
what are the requrment from a decimation filter for audio?
thanks,
nir

...outputStream.write toWrite
otherByte = false
} else otherByte = true
}
}
Basically you need to write every other byte in thePCM sample stream.
