title: Using Android's Linear Acceleration versus applying a low pass filter
body: <p>I am trying to determine the benefit of making use of Android's Linear Acceleration data as opposed to simply applying a low pass filter as presented <a href="http://developer.android.com/reference/android/hardware/SensorEvent.html#values" rel="nofollow noreferrer">in Androids API reference</a> and discussed <a href="https://stackoverflow.com/questions/6911900/android-remove-gravity-from-accelerometer-readings">in this other stackoverflow question</a>.</p>
  
  <p>I am asking as I am trying to get hold of a free app that records Linear Acceleration (as well as fullfils my other requirements (sampling rate, writing data to file etc...)). I haven't been able to find one, so I have considered just using an app that records using the standard accelerometer and then I'll simply apply the low pass filter to the data. Alternatively I could just write my own app to do what I need - but I don't have much experience in Android dev and this will take some time.</p>
