What I am trying to do is read the Pitch/Amplitude of one wave file, then increase the pitch of another wave file depending on the Pitch/Amplitude of the first. The second part should be simple enough for me. But what library do I need to use (and what method). It would be great if anyone can help. At the moment I am using the SoundTouch http://code.google.com/p/soundtouchnet/ library to up the pitch.
Any help or tips is appreciated.
Try using DirectSound. This tool allows you to do whatever with wav files. There are plenty of sources to find tutorials too.

I exploring internet for two days and still can't find a good head start for this. I want to write a code with c# to get a .jpeg binary file and decode it and display the image. everywhere I looked there is lots of explanation about jpeg algorithm but still I can't find good explanation about how to parse and decode this file. I mean for example how can I know Huffman DC table starts with what number and end's with what number?
I appreciate if someone can link me somewhere that I can find explanation about parsing binary jpeg file.
thank you and sorry for my english.
Trust me, it isn't something you can do. I wouldn't touch the thing with a pole long various meters...

Here there is the site of:
IJG is an informal group that writes and distributes a widely used free library for JPEG image compression. The first version was released on 7-Oct-1991.
There is the source code for libjpeg.
if you just want to take a look, here http://elm-chan.org/fsw/tjpgd/00index.html there is the source of
TJpgDec is a generic JPEG image decompressor module that highly optimized for small embedded systems.
it is even
Platform independent. Written in ANSI-C.
Being tiny it will be probably easy to reimplement in C# :-)
a bit of background:
this summer, i set myself a programming project,
where i want to make an E-jay clone(a program with simple drag-drop blocks which are little bits of music and beat to make a track)
now i dont really know where to start on the whole encoding music bit.
for example:
how does a sound file work?
how do i transform a piece of a sound file into a universal piece of sound information
how do i create a sound file from scratch
how do i add pieces of sound to a previously newly created sound file
im sorry if i seem like one of those guys that cant use google n stuff. but i have no experience with sound or anything on that part.
programming language: C#
ultimate goal: be able to encode a new mp3 file using small sound files which are inserted on certain points in the file to ultimatly make music
any help is appreciated,
thank you for reading my question.
I think you should check NAudio site - it has lots of examples.
Do some research into the MPEG compression standard, as you'll need to know about decoding as well as encoding. If you are going to be ambitious, maybe look into other audio file types as well.

Hi i'm new programming and i have written few application to access pdf content by using some dll files, but now my question is how can we write our own dll to access the pdf files. I know it's a big process but i'm very much interested to learn about this. any one please help me.
You can start by reading the PDF specification (warning 32MB behind this link) in order to understand how the PDF file format is implemented. This is necessary if you want to be able to parse it and extract the information you are interested in.
In the meantime (as this reading might occupy you during a certain amount of time) if you have pressing project deadlines you probably want to use an existing library such as iTextSharp.
I know it's a big process but i'm very much interested to learn about this.
That's true. I'd like to suggest to study some open source APIs (iTextSharp) and PDF SDK.
Seems like an odd request. I want to take in an image file probably a .dmg or a .bin, which uses HFS file system. Ideally id like to mount the image because all i need to do is get certain files from it, I don't need everything. They probably will be quite big files. Id be very grateful if I got some advice. Where do I start?
Simplifying answers as much as possible would be great also. Cheers.
Unless you want to port HFSExplorer to C# I would recommend you just use it...
I'm building an Android app that's reads comments from an MS Power Point file.
As i get it ill have to use some API, or build a program in C#.
The problem is that i can't find a way of doing that.
I would like to hear some suggestions or to hear from programmers that accomplish
that, or something similar.
If you can use the power point api that would be the best way however I don't know if that available on android. This is a link to the binary file specification for ppt files.
