Add Ball and Paddle
The first step is to add the ball to the center of the screen, and the paddle to the bottom of the screen. The dimensions of the paddle and its offset from the bottom of the screen are already constants in the starter code.
The next step is to get the paddle to move when you move the mouse. The paddle should be centered under the mouse, and should not go offscreen.
Move Paddle, Bounce Ball
The next step is to get the ball to bounce around the screen. We may have done this exact problem before…

add(ball);
}
function setupPaddle(){
paddle = new Rectangle(PADDLE_WIDTH, PADDLE_HEIGHT);
paddle.setPosition(getWidth()/2 - paddle.getWidth()/2,
getHeight() - paddle.getHeight() - PADDLE_OFFSET);
add(paddle);
}

suppose we sample music at a rate of 35 khz and quantize with 16 bits/sample. how many bytes are needed to store a 2-minute song in stereo? express your answer in terms of mb where 1mb
Answers
1Mb = 1/8 MB = 0.125 MB bytes are needed to store a 2-minute song in stereo.
How you figure out how many bytes are required to store a sound file?The rule of thumb for MP3 audio is that 2 minute of audio takes up about 2 megabyte.First, we need to compute the bit rate by multiplying the sampling frequency to its bit depth multiplied by the number of channels.Then We multiply the determined bit rate to the length of the recording in seconds. Audio recorded at 192kHz/24-bit takes up 6.5x the file space of audio recorded at 44.1kHz/16-bit.To calculate the file size of an audio file, multiply the bit rate by the audio’s duration in seconds. As a result, we obtain file size numbers in kilobits and megabits.
