For ex. if we are playing online music, can we simultaneously record that music to the hard disk using some device?
yes u can, there is a application called window movie maker which u should have it on your computer. u need to do some setting. open the application and click on TOOLS and then click NARRATE TIMELINE , then click on SHOW MORE OPTION and select first option under AUDIO INPUT SOURCE, then play any song online and while its playing, click on START NARRATION. it should start the recording and then click on on STOP NARRATION to stop the recording and then it will pop up save as window , save the song and play it. if it doen't play then again go under AUDIO INPUT SOURCE , select the next option and repeat all the step again. right now i am not sure which option is right one to select under AUDIO INPUT SOURCE. but i am sure its one of them because i have tried it and it worked . also must check under VOLUME CONTROL OPTION (find in entertainment section) none of the option is turned mute. all must be unmute. Good luck.
