I'm making a desktop dictionary which gives meaning with audio pronouncation and also user could record his pronouncation in .wav format..... and the application would tell him how prefect he is in his pronouncation.......! I want to known whether there is way that could help me in comparing the audio file in .wav format....? *Not the size actually but the pronouncation.....* I'm using visual studio 2008
Where can I find a free, very quick, and reliable implementation of FFT in C#?  That can be used in a product? Or are there any restrictions?
Have you ever notice the sunset's image in the sea? It's like long light path to the end of the horizon! I've attached a sample of this:     How can we explain this? I know that it can happen even in wave less sea or lake! Why is this path so continuous? I expected that sea should act like a mirror! Naive visualization of space-time curvature Can misused Schema.org hurt SEO? I've inherited a site where I noticed that    there is an excessive use of Schema.org in all navigation elements pages describing products are marked as itemtype="http://schema.org/CreativeWork"   So I'm wondering if these tags are sending the wrong message and not truly optimized. I realize that the nav (1) is done in some themes, but I'm more worried about (2). Can it be a hit SEO-wise to mislabel pages instead of products? "High response time" warnings in Google Webmaster Tools In my Google Webmaster Tools account, there are warnings about my site.     Some URLs listed in this sitemap have a high response time. This may indicate a problem with your server or with the content of the page.   What is the solution? How to allow to run su instantly after I added the user to the appropriate group What's the best way to take a segment out of a text file? What's a good way of extracting say, lines 20 -45 out of a huge text file. Non-interactively of course! What's the difference between $(stuff) and `stuff`? Question about Coulomb's law I am just very confsed about how to do these sort of questions where they give you a point in the middle of two charges. The farthest I've gotten in questions relating to coulomb's law, is using the formula \$F = {kq_1q_2 \over d^2}\$ to work out one of the unknowns when given two variables. Can someone please explain how you would do a question like this:  Two point charges of charge -2 µC and -3 µC respectively are separated by a distance of 15 cm. Point X is positioned at an equal distance away from each of the charges.      a. Determine the net electric field at X.     b. Find the point of equilibrium between the charges. Selection Tool doesn't rotate in Illustrator Why my selection tool doesn't rotate object? I selected the object and it doesn't work. How do I fix this? Types of polynomial functions. Quadratic, cubic, quartic, quintic, ...,? I would very much like to have a complete list of the types of polynomial functions. I know that theres:  Quadratic :                      (AX^2 + BX + C) Cubic     :               (AX^3 + BX^2 + CX + D) Quartic   :        (AX^4 + BX^3 + CX^2 + DX + E) Quintic   : (AX^5 + BX^4 + CX^3 + DX^2 + EX + F)   What are the names of polynomial functions to the further powers? Sexstic? Septic? Octic? I'm not sure, so if someone could enlighten me, then that would be great. Please provide a list that goes at least to the seventh power, but it would be nice if you could go further. Thanks. What is the advantage on saving the money for the overlord when you have 9 drones, and not filling your supply first and then getting the overlord?  In my theory, in the first case you get to wait the saving time with 9 drones, and get to wait almost the same time with 10 drones in the second case. Second case should be better, since 10 drones mine faster than 9? So why does everybody go with the first case?  All this is assuming you go 12 pool or something like that, where you will get more drones after the overlord. 6- and 8-pools are obviously different. Which one is correct: "wish I was here" or "wish I were here"? Possible Duplicate:          Which one is the correct form: "Wish I was here" or "wish I were here"? I've heard both of them many times but I don't know which one is correct. Require reason for post deletion and un-deletion? Could we have a method of explaining why we think a question or answer should be deleted?  It could work identically to closing a question, maybe with an additional text-input box (like the "Requires Moderator attention" flag option) to provide additional info because the reasons for deletion should really be more specific..  For example, "exact duplicate" doesn't explain to me the user has re-posted the same question, thus, it should definitely be deleted (not just left closed). Like with close-messages, these reasons would be listed under the deleted item (or answer).   I don't think comments are suitable, as they can be a pain to quickly.. "extract" deletion reasons from them - I have to scan through the comments, and they may all be irrelevant.  Equally, for un-deletion, it'd be useful to know why another user thinks a question should be restored. For example "new user deleted the question after they accepted an answer", or "Jeff went insane and started deleting any questions with the letter O in it".  I think requiring un-deletion reasons is possibly more important, since commenting is disabled on deleted questions - we have no way of explaining why we think it should be restored Why are only certain shutter speeds or apertures available? How can I use multiple overlay effects simultaneously in Photoshop? There are 3 overlay effects available in Photoshop as layer styles: Color, Gradient and Pattern. The problem: these effects come in a strictly fixed order!  Is it possible to make a translucent Gradient Overlay over a Color Overlay using only layer styles? Or a Multiply Pattern and Color Overlays? Java Hashmap: How to get key from value? Can "whatever" be split into two words? I tend to write, "say whatever they want", but I'm always tempted to write "say what ever they want". Is it acceptable to split the word in this context? Finding $\int^{\infty}_{0}\frac{\ln^2(x)}{(1-x^2)^2} dx$ Show that $d(z,a)=|\frac{z-a}{1-\overline{a}z}|$ is a metric on the unit disk For any $z, a$ in the open unit disk, we define$$d(z,a)=\left \vert \frac{z-a}{1-\overline{a}z} \right \vert$$  Show that $d$ is a metric on the open unit disk.     It is easy to show $d(z,a)=d(a,z)$ and $d(z,a)=0$ $\rm iff$ $z=a$. However, I am having trouble showing that it satisfies triangle inequality. Any help would be appreciated! Why teach linear algebra before abstract algebra? Is there a reason why most undergraduate curriculums put linear algebra before abstract algebra?  I'm asking this because personally it seems to be much easier to understand the architecture behind linear algebra as supposed to simply solving problems after a course in abstract algebra.
