Or even better, how to get the size of the amplitude or the volume of the wave sound every certain time.
In fact I need the two ways, the full waveform and measure it each time. the first one for have a view of the song wave and the second one for visual effects.
this is for Android (NDK) systems.
come on people, I don't ask for the full code answer, I just want you to tell me some advices or something that can help me. You can simply say that the question is hard or makes no sense. but say something.
Whatever, I researched a little bit and I didn't find the answer for the question, but I did find a better solution for the problem, and is a free library named "superpowered", simple, fast, cross-platform, and has all the functions for analize sounds.
hope this help people new to this world of sound programming
I'd like to be able to drag and drop from a DataGrid in a Flash application into an Excel spreadsheet. Is this possible? If so, how do I implement this?
Edit: Nine days without so much as a comment is pushing me to believe one of the following things:
This question is so easy to answer that everyone who reads it thinks, "Ah, the next guy will get it. This taco isn't gonna eat itself."
No one knows what Microsoft Excel is.
I'm so inept at coding for Flash that everyone who reads this question promptly dies from a stroke brought on by uncontrollable, hysterical laughter. Kind of like what happens when a person is exposed to the Joker's laughing gas.
The entire internet has been suddenly and completely vacated creating a vast, digital wasteland (except for me, obviously).
Adobe's PR person in charge of their Twitter account recently posted something highly offensive and everyone has finally gotten organized and successfully boycotted something without inviting me to the party.
Anyone want to clue me in to which one is, in fact, the truth?
Or maybe just tell me that what I want is stupid/impossible/not worth the effort?
The simple answer is no, it is not possible. Have you ever coded AS4? I spent 6 months coding stupid loops that randomly draw colored lines. It was terrible. Get out while you still can. I was coding some tangents outside by my school when a couple of engineering grads started making trouble. I coded one bad batch and my professor said "You're moving with the retards to coding 101" I hopped on my segway and rode home. I then hung myself.
I am looking for some advice on categorizing a library of sound effects. I have a large set of random sound effects, (think whistles, pops, growls, creaks, gunshots etc). I would like to be able to take a growl for example, and find the next growl that sounds the closest to the original.
Given a sound, what sound from my set sounds the closest to it.
I have done a fair amount of googling and have found two avenues that I am still researching. One is using echonest, although their "best match" support looks not promising for public users. The other option is diving into FFT and building my own matching algorithm. This is a fine option and would be a great learning experience but I wanted to get some opinions from others who might know a little more about sound processing; especially short clips .5sec - 3sec range, not full length music.
Thanks!
I have worked in movie postproduction for years and as far as I know, there is no way to do that automatically. Every file has meta information in its file header which describes what the sound is like. You are then actually not searching for the file names but in the meta string.
I don't think that it is trivial to sort effects programmatically as two effects that sound similar might be totally different if you look at the waveform.
You would need to extract significant information about a sound that you can then compare.
I am also not a DSP expert, maybe there are methods to do this
If you're interested in trying to build your own system to do this, I can suggest a few keywords that might help to refine your Google searches. In the academic research community, the task you're describing is often called "content-based audio searching". I know there's been a lot of work done on it, and though most pertains to music, sound effects have definitely been the focus of a number of studies.
You might want to start with the work of Pedro Cano.
Also, I recently heard about a company that's doing similar work. You might want to check out products from Imagine Research.
Those are just a couple of ideas off the top of my head. I'm not %100 sure they'll be helpful. If they are, please let me know!
How do you get yourself in the "zone" for programming? As a CS undergrad I've been finding it difficult to get focused in. I think part of my problem is I do not have "proper" workspace living in the dorms. Any ideas or tips? (Perhaps good thinking music, whiteboards? etc)
The best way I found yet is to turn off the Internet. Since opening my browser and browsing to some random site has become almost a reflex, I deactivate my network card for the time I need to work. This way I have the time to realise what I am doing before it is too late. The Internet must be the number one "Zone Killer" I know...
Truthfully, nobody can tell you about you, they can only tell you about them. That may help, or it may not.
I've seen people able to get "in the zone" on a commuter train car. I've seen people who have it broken when the air conditioner kicks in.
Here's what works for me:
Need no people talking to me. I can't keep the ideas juggling while explaining them or having other ideas tossed in to the mix. I know, pair programming can be great - but I've never been "in the zone" while pair programming.
Music is okay, but no playlists with wildly different styles, or songs I absolutely love.
It almost always kicks off when I'm frustrated by something but then have an idea how to solve one aspect of the problem... then things flow from there.
I need a desk clean enough that nothing on it distracts my attention and makes me think - no dev magazines with interesting tech on the cover, no dishes with mold on them, etc.
I need about 20 square feet to get up, pace for 2-3 steps, then sit back down. Too much room gets me too far away from the computer. Too little room and I feel confined.
As soon as I solve the problem, I'm normally out of the zone. A phone call or person at my desk will break it. Stopping to answer email "toast" will kill it too.
But again, this is me. All of this may actually be the reverse for you - You'll find it eventually, I'm sure. Just don't give up, and don't take personal anecdotes and advise or internet blog posts as absolute truth - "the zone" is very much a personal thing.
One small thing which helped me a lot was to get noise cancelling headphones. These are a bit pricey, but being able to switch on silence is great!

I've always felt that my graphic design skills have lacked, but I do have a desire to improve them. Even though I'm not the worlds worst artist, it's discouraging to see the results from a professional designer, who can do an amazing mockup from a simple spec in just a few hours. I always wonder how they came up with their design and more importantly, how they executed it so quickly.
I'd like to think that all good artists aren't naturally gifted. I'm guessing that a lot of skill/talent comes from just putting in the time.
Is there a recommended path to right brain nirvana for someone starting from scratch, a little later in life? I'd be interested in book recommendations, personal theories, or anything else that may shed some light on the best path to take. I have questions like should I read books about color theory, should I draw any chance I have, should I analyze shapes like an architect, etc...
As far as my current skills go, I can make my way around Photoshop enough where I can do simple image manipulation...
Thanks for any advice
Most of artistic talent comes from putting in the time. However, as in most skills, practicing bad habits doesn't help you progress.
You need to learn basic drawing skills (form, mainly) and practice doing them well and right (which means slowly). As you practice correctly, you'll improve much faster.
This is the kind of thing that changes you from a person who says, "It doesn't look right, but I can't tell why - it's just 'off' somehow" to a person who says, "Oops, the arm is a bit long. If I shorten the elbow end it'll change the piece in this way, if I shorten the hand end it'll change the piece this way..."
So you've got to study the forms you intend to draw, and recognize their internally related parts (the body height is generally X times the size of the head, the arms and legs are related in size but vary from the torso, etc). Same thing with buildings, physical objects, etc.
Another thing that will really help you is understanding light and shadow - humans pick up on shape relationships based on outlines and based on shadows.
Color theory is something that will make your designs attractive, or evoke certain responses and emotions, but until you get the form and lighting right the colors are not something you should stress. One reason why art books and classes focus so much on monochrome drawings.
There are books and classes out there for these subjects - I could recommend some, but what you really need is to look at them yourself and pick the ones that appeal to you. You won't want to learn if you don't like drawing fruit bowls, and that's all your book does. Though you shouldn't avoid what you don't like, given that you're going the self taught route you should make it easy in the beginning, and then force yourself to draw the uninteresting and bland once you've got a bit of confidence and speed so you can go through those barriers more quickly.
Good luck!

That's a difficult thing. Usually people think "artistic skills" come from your genes but actually they do not.
The bests graphic designer I know have some sort of education in arts. Of course, photoshop knowledge will allow you to do things but being interested in art (painting specially) will improve your sensitivity and your "good taste".
Painting is a pleasure, both doing it and seeing it. Learning to both understand and enjoy it will help and the better way to do it is by going to museums. I try to go to as much expositions as I can, as well as read what I can on authors and styles (Piccaso, Monet, Dali, Magritte, Expresionism, Impresionism, Cubism, etc) that will give you a general overview that WILL help.
On the other side... you are a programmer so you shouldn't be in charge of actually drawing the icons or designing the enterprise logo. You should however be familiarized with user interface design, specially with ease of use, and terms as goal oriented design.
Of course, in a sufficiently large company you won't be in charge of the UI design either, but it will help anyway. I'd recommend the book About Face, which centers in goal oriented design as well as going through some user interface methapores and giving some historic background for the matter.
I'm no artist and I'm colorblind, but I have been able to do fairly well with track creation for Motocross Madness and other games of that type (http://twisteddirt.com & http://dirttwister.com).
Besides being familiar with the toolset I believe it helps to bring out your inner artist.
I found that the book "Drawing on the Right Side of the Brain" was an amazing eye opening experience for me.
One of the tricks that it uses is for you to draw a fairly complicated picture while looking at the picture upside down. If I had drawn it while looking at it right side up it would have looked horrible. I impressed myself with what I was able to draw while copying it while it was upside down.
I did this many years ago. I just looked at their website and I think I will order the updated book and check out their DVD.
I have a BFA in Graphic Design, although I don't use it much lately. Here's my $.02.
Get a copy of "Drawing on the Right Side of the Brain" and go through it. You will become a better artist/drawer as a result and I'm a firm believer that if you can't do it with pencil/paper you won't be successful on the computer. Also go to the bookstore and pick up a copy of How or one of the other publications. I maintain a subscription to How just for inspiration.
I'll see if I can dig up some web links tonight for resources (although I'm sure others will provide some).
most importantly, carry a sketch book and use it. Draw. Draw. Draw.
Drawing is probably what I'd recommend the most. Whenever you have a chance, just start drawing. Keep in mind that what you draw doesn't have to be original; it's a perfectly natural learning tool to try and duplicate someone else's work. You'll learn a lot. If you look at all the great masters, they had understudies who actually did part of their masters' works, so fight that "it must be original" instinct that school's instilled in you, and get duplicating. (Just make sure you either destroy or properly label these attempts as copies--you don't want to accidentally use them later and then be accused of plagiarism..)
I have a couple of friends in the animation sector, and one of them told me that while she was going through college, the way she was taught to draw the human body was to go through each body part, and draw it 100 times, each in a completely different pose. This gets you comfortable with the make-up of the object, and helps you get intimately knowledgeable about how it'll look from various positions.
(That may not apply directly to what you're doing, but it should give you an indicator as to the amount of discipline that may be involved in getting to the point you seek.)
Definitely put together a library of stuff that you can look to for inspiration. Value physical media that you can flip through over websites; it's much quicker to flip through a picture book than it is to search your bookmarks online. When it comes to getting your imagination fired up, having to meticulously click and wait repeatedly is going to be counter-productive.
Inspiration is probably your biggest asset. Like creative writing, and even programming, looking at what people have done and how they have done will give you tools to put in your toolbox.
But in the sense of graphic design (photoshop, illustrator, etc), just like programmers don't enjoy reinventing the wheel, I don't think artwork is any different. Search the web for 'pieces' that you can manipulate (vector graphics: example). Run through tutorials that can easily give you some tricks. Sketch out a very rough idea, and look through web images to find something that has already created.
It's like anything else that you wish to master, or become proficient in. If you want it, you've got to practice it over, and over, and over.
I, too was not born with a strong design skillset, in fact quite the opposite. When I started out, my philosophy was that if the page or form just works then my job was done!
Over the years though, I've improved. Although I believe I'll never be as good as someone who was born with the skills, sites like CSS Zen Garden among others have helped me a lot.
Read into usability too, as I think usability and design for computer applications are inextricably entwined. Books such as Don Norman's "The Design of Everyday Things" to Steve Krug's "Don't Make Me Think", have all helped improve my 'design skills'... slightly! ;-)
Good luck with it.
As I mentioned in a thread yesterday, I have found working through tutorials for Adobe Photoshop, Illustrator, InDesign, and After Effects to be very helpful. I use Adobe's Kuler site for help with colors. I think that designers spend a lot of time looking at other's designs. Some of the books out there on web site design might help, even for designing applications. Adobe TV has a lot of short videos on graphic design in general, as well as achieving particular results in one of their tools. I find these videos quite helpful.
