P-7 Audio

Good morning!

How are you doing?

Here I present you your new audio practice. This time, you will have to build on an electronic song from nowhere. So, what do you have to do?

First, go to http://soundation.com/

Click on enter the studio and here you are: you will have an electronic mix table to build your own songs. Take your time trying out its features. It's easy to use: you only have to select which track you want to use, click on it and drag it to the central space. You will be able to rearrange, to extend, to combine, etc different tracks. Just try on and do your best!

Finally, on the File menu, select "Export" and save it in your folder with .wav extension. Once done that, send me the file that will appear in your folder.

The final lenght of your project has to be of about 3 minutes.

I hope you enjoy it! Cheers!

Good morning!

In this practice you will have to turn-into-robot some kind of voice.

You will have to search some audio with plain voice and then, search for how to convert this voice into robot voice, and do it.

I will specially evaluate your autonomy and independence at researching and working.

Let's work!

Hello everyone!

Today I want you to finish and send me all the practices you have already started, and a little more.

Try to generate these waves:

-sinusoidal, 30 Hz
-squared, 30 Hz
-triangle and/or sawtooth, 30 Hz

And compare them. How do they sound? Which sounds better? Why do you think so?

Try now to generate a 2000 Hz wave with the same three waveforms. Answer again the same questions.
Finally, generate a wave at the superior limit of your hearing amplitude, which you found out at last class. Answer the questions again.

Send me the answers in a doc document or directly in the e-mail. And remember that, if in English, the document will be more valuable.

Relax is over: It's showtime!

Good afternoon!

In this new post we are going to learn about different waveforms and how they are listened by us.

Depending on the frequency of the signal, the tone we listen is higher or lower. Human ears are supposed to be able to hear frequencies between 20 Hz and 20 KHz. Human voice is supposed to have a frequency between 33 Hz and 3 KHz. So there's no human being capable of screaming at a non-hearable frequency.

In this practice I want you to generate tones and research about their features:

Task list: Answer in the mail or in a word document. You will only have to send me this document

1.- Generate a sinusoidal 30 Hz - 5 seconds-long wave. Can you hear it? How does it sound?
2.- Generate a sinusoidal 2KHz - 5 seconds-long wave. Can you hear it? Compared to the last, how does it sound?
3.-  Generate a sinusoidal 1Hz - 5 seconds-long wave. Can you hear it?
4.-  Generate a sinusoidal 400KHz - 5 seconds-long wave. Can you hear it? Why?
5.- Try to generate different frequency sinusoidal waves. Which is your frequency-listening limit?
6.- Generate a sinusoidal 1KHz tone. Generate a squared 1KHz tone. Generate noise. Which are their differences?
7.- Generate a DTMF (Dual Tone Multifrequency). What does this remind you?
8.- Look for information in Internet about the DTMF. Llok for the frequencies used in each number in a mobile phone. Can you generate DTMF tones in Audacity related to your mobile phone?

Send the document to my mail or answer directly in it.

If you answer in English you will have the chance of getting an extra point.

Good luck!

P-what? Looking for the Excellence

Good afternoon!

Since I now some of you have finished P-3, I suggest some kind of extra practice that I will bear in mind at time of putting your marks.

This time, I suggest you to usea Audacity to bring up some audio track with inffluences of something about now: dubstep.

Surf the net and find some information about dubstep. then, try to do something with that. For example, what will happen if you make a dubstep version of P-3 or (P-2)?

Here is some base that you can cut and edit to use or just to follow as a guide for creating your own bases: http://www.jpelirrojo.com/BasesGratis/Bases_de_libre_uso_Vol.2/09_Diciembre_2011_140bpm.mp3

If you want to create your own bases, try creating the bass with the generation tool > chirp > sinusoidal from 20 to 100 Hz. From this point, its all your effort!

I know this may seem difficult, and it absolutely is so, but, if you're interested, try out: maybe you will discover your abilities and you may be the next hit on youtube!

We're seeing soon,

Xavi
