How i can record multi track using my home pc??
i want to record each track individually so i can edit effects on each track as neccessity.
which hardware or/and software require to complete this job?
As the previous answer already stated, you will need both an audio interface, and a DAW (Digital Audio Workstation), but I'll expand on this a little to get you started in the right direction so you can make an informed decision when acquiring these tools.
To put it simply, an interface is a box that takes analog signals, and converts them into digital signals that can be interpreted by the computer (and vice versa). In many cases, this box acts as the main hub for all audio coming in and coming out of your computer.
Interfaces come in many different configurations (and price points) based on the user's needs. A basic configuration might have:
Interfaces with multiple inputs will generally let you record all inputs at the same time, and will be saved as separate tracks inside your DAW.
Since interfaces can range from about $100 to several thousand dollars, I would suggest figuring out what your needs are (how many instruments do you need to record at one time? is portability a factor? How do you plan to connect it to your computer? etc) and then visit your local music store.
Presonus, M-Audio, and Focusrite are a few brands I've really enjoyed, and all have great options at several price points. Not trying to push you in any sort of direction, but it may be a good place to start with your research.
The DAW is software that allows you to save, edit, arrange, and playback your audio files. I won't go into depth on the definition, but you will definitely be needing one for multi-track recording.
Many companies are putting out free "lite" versions of their software, which works great for general purposes, and is a really great opportunity to try out the software before buying a more professional version.
A few free options I would recommend for PC are:
Again, the choice of DAW depends on your needs, but a free version will probably be enough to get you started, and allow you to make an informed decision if/when you need to upgrade
If you don't want a very bad sounding finished product, on top of these (two) answers, you will need something to output the sound for more accurate monitoring. Something a lot better than PC speakers. Either half-decent headphones, active monitors or passive monitors and an amp.
If you are truly starting with no knowledge on the subject, I would recommend buying a book before anything else!
