- RMS of each level is used as a parameter for deciding lienairy.

- * Solves a linear least squares problem to obtain a N degree polynomial that fits

- *
- * The input consists of two vectors of data points X and Y with indices 0..m-1.
- * The output is a vector B with indices 0..n-1 that describes a polynomial
- * that fits the data, such the sum of abs(Y[i] - (B[0] + B[1] X[i] + B[2] X[i]^2 ... B[n] X[i]^n))
- * for all i between 0 and m-1 is minimized.
- *
- * That is to say, the function that generated the input data can be approximated
- * by y(x) ~= B[0] + B[1] x + B[2] x^2 + ... + B[n] x^n.
- *
- * The coefficient of determination (R^2) is also returned to describe the goodness
- * of fit of the model for the given data. It is a value between 0 and 1, where 1
- * indicates perfect correspondence.
- *
- * This function first expands the X vector to a m by n matrix A such that
- * A[i][0] = 1, A[i][1] = X[i], A[i][2] = X[i]^2, ..., A[i][n] = X[i]^n.
- *
- * Then it calculates the QR decomposition of A yielding an m by m orthonormal matrix Q
- * and an m by n upper triangular matrix R. Because R is upper triangular (lower
- * part is all zeroes), we can simplify the decomposition into an m by n matrix
- * Q1 and a n by n matrix R1 such that A = Q1 R1.
- *
- * Finally we solve the system of linear equations given by R1 B = (Qtranspose Y)
- * to find B.
- *
- * For efficiency, we lay out A and Q column-wise in memory because we frequently
- * operate on the column vectors. Conversely, we lay out R row-wise.

-Android Audio Quality Verifier App
-==================================
-
-This app runs a set of audio quality tests on an Android device,
-to verify the end-end sound recording path.
-
-If any of these tests fail, the device is probably unsuitable
-for demanding audio tasks such as speech recognition.
-If all the tests pass, the device audio is of a good standard.
-Note that not all possible audio defects can be detected by this
-test suite, so passing does not guarantee ideal audio quality.
-
-Hardware setup
---------------
-
-The required physical set-up consists of a powered speaker,
-connected to the Android's headphone output by a standard
-audio cable.
-
-For loudspeakers which come in pairs, you only need to use
-one speaker (typically the powered or master speaker); you
-can leave the second speaker disconnected.
-If the speakers are stereo within a single unit (sometimes
-with speakers facing in opposite directions), place the phone
-in front of either of them.
-Speakers with multiple drivers per channel (e.g. a tweeter
-and a woofer) are not suitable.
-
-The phone should be placed in front of the centre of the
-speaker cone. The distance from the speaker will be adjusted
-during calibration; typically you could expect it to be around
-3cm or so.
-Use a supporting platform such as a stack of books to raise
-the phone to the correct height to line up with the speaker.
-
-Bluetooth connection is possible but cable connection is
-usually preferable.
-
-Recommended loudspeakers
-------------------------
-
-Using suitable loudspeakers ensures that test failures highlight
-problems with the Android device under test, and not limitations
-of the loudspeakers. The following loudspeakers work well for this
-purpose:
-
-1. Yamaha NX-B02
-
-Use on AC power, not batteries.
-This speaker works well with Bluetooth as well as a wired connection.
-Note that it's not uncommon for the devices to exhibit different
-bugs under Bluetooth.
-
-2. Cakewalk MA-7A (Edirol / Roland)
-
-The "Bass Enhancer" feature MUST be switched off.
-Note that it turns itself on again every time the speakers are
-powered on, so it is easy to forget to switch it off!
-
-Software setup
---------------
-
-1. Build the application's apk.
-2. Install the apk using adb.
-3. Run the app.
-4. Click "Calibrate". Position the phone as described in
- Hardware setup above, with the microphone facing the speaker,
- and adjust the volume of the speaker until the status message
- indicates it is correct.
-5. Click on any test in the list to run it, or "Run All" to run
- each test in sequence.
-6. Click "Results" to view the outcomes. A correctly functioning
- device should pass all tests.
-7. Click "Send by email" from the results page to send the
- results to an e-mail address of your choice. The recordings
- made are also attached as raw 16 bit, 16 kHz audio files to
- help you diagnose any failed tests.
-
-Q&A
----
-
-Q. What if the sound level check fails?
-A. Go back to the calibration step before running any other test.
- Make sure the device has not been moved.
- We also recommend that once the setup is calibrated there are no
- moving objects or people near the device under test, since these
- will change the acoustic properties of the environment from the
- calibrated state.
-
-Q. Some of the tests sound very loud. Is this normal?
-A. The clipping test will generally be very loud indeed;
- the others should be at a moderate volume.
-
-Q. What sort of room should the tests be performed in?
-A. Any, as long as the background noise levels are kept low, to
- avoid interference with the test recordings.
