audio frequency retrieval

[sanaahmad17]

ASLAMOALEKUM,

How i can get per second frequency for an audio file in C#.

if anyone tell me the way/code i could generate a text file/array containingg the per second frequency of the audio file as it is loaded to the application.


thanks!

one way is to use DirectSound of DirectX; there are a bunch of functions that can be used to manipulate sound.

you can use Managed DirectX by installing DirectX SDK 9.0 and use ready to use libraries for C#.

also please check this sound engine for C++ and C#:

irrKlang:

It has all the features known from low level audio libraries as well as lots of useful features like a sophisticated streaming engine, extendable audio reading, single and multithreading modes, 3d audio emulation for low end hardware, a plugin system, multiple rolloff models and more

Hello, I just downloaded the library and tried using it with a different filename location instead of using the default one, but I have got an error. would you please recheck to see what is it going on ? Also, why it could not work with a media dat file ?

thanksalot Toraj58, i have already tried both these libraries but didnt get any required result.. well let me explore again.. hopefully this time i would get anything useful....

if anyone knows abt any particular func (belonging to these or any other library) which can help me achieving my target..do tell me!

thanks again!
