Making sound

1. Sound moves through what medium?

Liquid?

2. Briefly describe how a microphone works, in particular what does it gather and what does it produce? 

A microphone has small membrane that vibrates, it also has a mchanism that translates moovements of the membrane into electrical signals. When acoustical waves are translated into electrical waves by the micrphone. The higher the pressure the higher voltage, the lower the pressure the lower the voltage.

3. What unit is used to measure sample size?

 Measured in bits.

4. What unit is used to measure sampling rate?

 Measured in Hertz (Hz).

5. How does sound quality vary with sample size and sample rate.

If sample size is increased, the quality increases. 
increase sample rate it also increase the sample quality.

6. What is another name for sample size?

 Sample format.

7. From the information given which offers better quality sound, FM radio or AM radio?

FM radio has better quality sound.

8. Why not record all sound in extremely hight sample sizes and sample rates?

To much memory and space would be taken up.

Ringtone

My Ringtone made on Audacity.

I have made this ring tone on the computer program, Audacity. First i downloaded the song 'Another world' by one direction and when they say 'Hi we're one direction'.

The i added the sounds to the program and trimmed the parts i didnt want, i did that by selecting what i wanted to trim then went to 'edit' and 'trim'.

I then selected the end part of the song 'Another world' and went to 'effect' and 'base boost' to add a strong base to that section.

Then i selected both the song itself and when the boys talk and made the pitch of their voices high by; clicking 'effect' and 'change pitch'.

Once I had finished creating the ringtone, i saved it. To upload it on my blog i needed to make it a movie so I went onto movie maker uploaded three pictures onto movie maker that realated to One direction and their song 'Another world' and placed the ringtone i created onto it.

 I then had to save the movie by clicking 'save movie' then 'forcomputer'.

Questions and Answers

 1) Describe what software you used and why you chose it.
The computer software I used to complete my animation was Inkscape and Movie Maker. I used Movie Maker because it allowed to make frames per second. I used Inkscape because it creats victor images which allows you to move different parts of an image, without moving the whole image e.g. if I created a image on Inkscape of a person and want to move its hand I can just click on the hand and drag it without his whole body moving with the arm. Then we save frames as bitmap images as we want to save the whole image not just one section. Also when you want to zoom into the picture it doesnt become pixalated,  unlike some programs such as paint, this is again because Inkscape makes victor images and recognises images as shapes and figures and paint is bitmap images and doesnt recognise images.

2) Describe the creation process you followed. 
      1. Open Inkscape and make the background colour a solid colour and fix the size of the canvas to 400 x 400 pixels. 
      2. Draw the characters or objects that you would use to create your animation; draw them on Inkscape. Then fill them and colour them
      3. Export each movement made as a bitmap image. 
      4. Place all bitmap images (frames) in Movie Maker software
      5. Change the duration of the frames to whatever time you want that frame to last for.

3) What image format were you saving your work in during development of the frames?
I was saving my work as the image format, svg.

4) What image format did you save your frames as?
The image format I was saving my frames under was called, png.

5)  What frame rate were you aiming for?

I was aiming for 30 frames persecond as 30 fps is a good rate and 15 fps is what I wasnt aiming for as it is a bad rate.

6) What is the final size of your animation in Mb?

The final size of my animation is 1.19 Mb.

7)  What difficulties did you encounter and how did you overcome them?

During th process of making my animation I didnt overcome any problems or difficulties. I had enough time to create my animation, the program never played up on me or randomly shutdown. Inever had trouble saving my work or finding my files, I was up to date with everything and constantly saved my work, infact I did a little extra with my animation and added sounf affects. I really enjoyed making my animation and my final product runs smoothly and im very proud of what I have created.

My Final Animation

Process of making my Animation

16/3/12
Today I decided on what my animation was going to be about. I was going to use a few images from google and re-draw them changing a few features. My animation was going to be about One Direction, consisting of the band members; Louis, Niall and Harry.
The images i was going to use to help me draw the characters are:

17/3/12
Today I started drawing my first character Louis. On the left you can see the image I drew myself on Inkscape. On the right I have proved that I drew it myself on Inkscape by showing the nodes on the carrot. I saved this character in a seperate Inscape file called 'Louis'.

18/3/12
Today I started creating my other two characters; Harry and Niall and also a small carrot. The picture on the left shows the image I drew on Inkscape. The image on the right shows the nodes on both characters to prove that I drew the image myself on Inkscape. I saved these character in a different Inkscape file called 'Harry and Niall'.

19/3/12

Today I exported bitmap images to create my final animation which would move. I started of by going to 'Document Properties' to make the background not transparent, so I made the background colour grey. I also set the size of my canvas to 10cm by 10cm.

Then I placed my character (the carrot one) onto the background and used the text tool to write the letter 'Z' to represent snoring, as the character is sleeping. I exported a few bitmap images of the letter 'Z' appering on the screen one by one.

20/3/12

Today I added speach bubbles to create the illusion that the character is dreaming. To prove that I have created the cloud on the left using Inkscape, you can see on the left the cloud and on the right you can see  the nodes of the cloud. I exported a few bitmap images of the clouds growing larger and larger, one by one.

21/3/12

Today I placed my two characters, Niall and Harry, into the largest cloud/bubble. I then exported bitmap images of Niall and Harry moving back and forth so it looks like they are fighting over the carrot they are holding. (The carrot is actually Louis')

22/3/12

Today I made the carrot, which Harry and Niall are holding,  grow bigger and bigger and so then it finally explodes. Just before the carrot explodes I changed the facial expressions of both Harry and Niall to a shocked face as they dont know why the carrot is growing larger. While I was creating all this I was also exporting the images.

To show that the carrot has exploded I created a 'Boom' sign using the Inkscape tool called 'Bezier Tool'. To prove I created the image on Inscape you can see the 'Boom sign on the left and the nodes on the image on the right.

23/3/12

Today I created facial expressions for Harry and Niall for when the carrot exploads. When I created them I exported bitmap images of their facial expression changing. Then I made Louis open his eyes and have red cheeks as he is shocked that his carrot has exploded, but then I make his eyes look down to his carrot, then he realizes it was all a dream. Then the clouds/bubbles disappear the screen, one by one. All this has been exported in bitmap images. 

24/3/12

I created a series of bitmap images today of Louis' hand moving back and forth, showing affection to his carrot. I then used the 'Text' tool to type in the word 'My Carrot!!' The entered the screen one by one in different colours, to do this I exported the first letter as a bitmap image then added on each letter seperatly continuing to export the images as a bitmap image.

25/3/12

Today I 'zoomed in' to Louis. But what I really did was make Louis just a little larger and exported a bitmap image then i make him larger making him more to the center, then exported the image as a bitmap image, and done that untill Louis was as large as the screen/canvas. 

26/2/12

I created, using Inkscape, the symbol for One Direction. To prove that I have drawn this picture myself using Inkscape, you can see the image on the left is the 1D symbol and on the right you can see the nodes on the number 1. 

later today I made the 1D symbol, I created earlier, grow larger in-front of Louis. I did this by using the same 'technique' I used to make Louis larger (zoom in).  

27/3/12

Today I used all my Bitmap images and created my animation by placing those images in a program called 'Movie Maker' I made each frame have different duration between 0.03-o.40

I thought I would just be a little different and work ahead of the class and add sound to my animation, so I found snoring sounds, a boom sound and One direction saying 'Hi, we are One Direction'.
