If you are in Windows Media Player then go into your Enhancements and look in the taskbar thst appears down in the bottom left.  Press the arrows and find GRAPHIC EQUALISER, and pull 1KHz to the top mark.  This should help because it works for me, it makes it louder but may distort the sound a bit.  Experiment with the other ones and find a balance that suits you.  You can always reset....

You musto to produces vibrations in your objeect, but you need a method to:\n\n1. producing vibration of differents frequencies\n2. A equiptment to measured the amplitud of the vibrations\n\nWhen the amplitud is big, you found the resonance frequency.\n\nYou should to observe that this maximum not occur at all frequencies, only a certain frequencies.\n\nOr you use a "stroboscopy light " to do it... produces the vibartion in your object and measure the vibration changing the stroboscopy frequency light.

Yes but not with so few details. You need to start with the obvious:\nTry some different speakers, make sure its not muted in windows etc

first create a mixer.  then create a drum machine and makes suer it's plugged in correctly by flipping around to the back.  Now play with the drum machine until you lay a fat beat.  Your started.\n\neverything else is reading the manual and experimentation.

I don't think there is a good way. You'd need to write code to filter the tone out of the microphone data, figure out the frequency, and give feedback to the user. It can be done, but it would be way more trouble than it's worth in any language I can think of. IMO you should just put up the $20 for a pocket tuner.

You'd need a sound converter program.  You can find one easily on www.download.com.

To mix songs:\nClick and drag both songs from the explorer into your project. They will each make their own track. Use the paint tool (looks like a paint brush) to "paint" each track. They will then be mixed.\n\nTo get the static sound:\nSelect the "ACID FX" tab at the bottom of the screen. Check off (either) "EQ" and/(or) "Distortion." Adjust the Treble, Mid and Slew settings to control the amount of static.\n\nFor online manual:\nGo to the "Help" menu and select "Contents and Index."\n\nHope I helped! Feel free to ask if you have any more questions.

You can try building a sound isolating drum riser. There are commercial product s available:\nhttp://www.auralex.com/sound_isolation_platfoam/sound_isolation_platfoam.asp\nOr you can try styrofoam or similar (and cheaper) alternatives.
