How do you put music from youtube onto your CD?
Use an online downloading tool like KeepVid to convert the desired YouTube video to a MP4. Then, drag the video file into the blank CD and burn as instructed by the software you use for the task.
It is definitely not legal to upload movies on YouTube. It's not legal to upload any movie on the internet for that matter. This violates copyright infringement, but YouTube will most likely delete the video and your account if you do so.
Hope this helped!
Why is iTunes charging 1.29 for a song?
All songs on itunes are now DRM-Free. This means that songs can now be played on non-apple devices and can be shared more easily between computers. This new feature makes the songs worth more.

How did you use a cassette player in the old times?
Answer
First you press eject on the player. This opens the door which you have to put the cassette into. Then (and a safety WARNING is issued here), you insert the tape into the slot provided. Then you push the door closed and press play! A simple but genius invention which had touched many hearts, minds (and throats) along its history.
Answer
It worked the same way a CD player or DVD player works: you put it in and press play, fast forward, rewind, stop, pause, etc. Except, with a cassette player, "rewind" literally meant rewinding the actual tape inside the cassette. The music or video was encoded on one long plastic ribbon that wound around two spools (like spools of thread). When the tape played, it wound itself around the spool on the right, and as the winding tape passed over a certain place, the material on it would be played. When you rewound it, it would rewind itself back around the left spool.
Do people still record on vinyl records anymore?
The vinyl record continues to be a popular format with nearly 2 million vinyl albums sold in the US in 2008 and the British Phonographic Industry (BPI), claim the number of 7 inch vinyl singles sold in the UK rose from 178,831 in 2001 to 1,072,608 in 2006.
no you can't. if you want to run separate amps for your subs they both have to be the same amperage and preferably same model. you can use the 1000 w amp on the subs and get a nice amount of bass depending on what size and model subs you have. then just use the 400 w amp for your mids and run the highs off the radio lines. try that and you will hear some good sounds. you will also need a crossover as well. hope that helped.
Where can you download mp3 plus g karaoke music?
The places to download music for kids karaoke are many and varied. The best place to start would be the mp3 section of the Amazon website. You can either download single songs or whole albums.
Why do you call vinyl records vinyl records?
Vinyl records are called such because of the material Lp's (33 1/3 RPM) and 45's RPM records are made out of. Before the creation of Lp's in 1948, most records were pressed with shellac and more properly called gramophone records.
How do you download music from PC to Sony PSP?
Sony mp3 players tend to be only compatible with PC (windows-based computers). Make sure you have one of those, first! If any discs came, install them! Most of the time you plug in a cable and your computer recognizes the device. It might turn on automatically when plugged in, but if it doesn't, turn it on.
If you're looking for a specific source, downloading programs such as "Kazaa" or "Ares" have a "Shared Folder" in which your songs are stored. These should be dragged to the folder or source that opens when you plug in your device.
It should be mentioned some of the Sony MP3 Players require you to use special software and likely you can't just drag and drop in windows explorer like we would all hope and expect. The one i have experience with is 1gb that plays MP3 , WMA , WAV , ATRAC3 , ATRAC3plus, has an FM tuner and built in USB plug.
You should be able to use most any app that support portable devices for example in Windows Media player you go through your playlist or add the songs you want to a playlist then click SYNC at the top right click the song you want and click 'Add to Sync' then when your done selecting click START SYNC. You may have to add your music collection to WindowsMediaPLAYER if you're like me you never use it. I THINK Winamp and Sonic will let your SYNC your player but i am quite sure iTunes will not.
What is the best home karaoke system?
A home Karaoke system to get would be Home Karaoke by Hasbro for the little ones or Sing, Sing, Sing by Sing like the Stars; it makes you go for your passion
The best home karaoke systems are manufactured by VocoPro and Best Media (U-Best). Never purchase a toy karaoke machine for a child, as doing so is virtually certain to create disappointment, causing the child to lose interest in karaoke, akin to giving a child a toy telescope.
Any Bluetooth headset is compatible with the PS3. <<< NO!!! THIS IS WRONG!!!>>
u actually need a special headset that clearly says ps3 capible, some headsets will play havok with ur wireless controllers!!!!
try Wikipedia I'm pretty sure ps3 is compatible with most headsets.
Where can you legally download free Hindi songs for an mp3 player?
Reverb Nation and Last.FM are good sites to download free Hindi songs. Download Hindi MP3 is another good site to download Hindi songs.
Where can you download naruto in an mp4 format?
GeekIsLuv says: If you don't have high-speed internet, you might as well stop reading. I'm going to assume you've never heard of torrents. A torrent is a program that allows you to download something through different people (try asking 'What is a torrent' or researching it on Wikipedia or some other site.) You'll need a client to download through the torrent (I use uTorrent) and a place to download the actual torrents (I use PirateBay or just google something like 'Naruto the Movie 2 Torrent.') Download the torrent and open it in uTorrent. The more seeds, the better -- if there are NO seeds, you won't be able to download. You'll figure it out, if you try.
Can you take portable turntables camping with an RV?
Yes you can grammaticly bring vinyl records like 33rpm LPs, 45rpm and the 78rpms camping as long if you want to listen to music on a 33, 45, or a 78
as you want to do that when its neccesary and acceptable you can play
music there if you want to listen to a 33 and any labels you want and
also 45 and a 78 with a RCA Victor and any old 78rpm phonograph record
labels all you want to play it on a turntable when its more acceptible.
You must bring speakers to go with it when it is more appropiate to do
that. You can listen to 33rpms 45rpms, 78rpms that was is recorded in the
1900s, 1910s, 1920s, 1930s, 1940s, 1950s, 1960s, 1970s, 1980s, 1990s,
2000s and the 2010s. When its exactly okay it wont be a very strict
issue when its absoblutley more neccessary to take those camping
Who invented the walkman radio?
=The Radio was around long before the walkman, The radio was out during WWII and earlier and the walkman only came out in around the 70's so if i am correct that is after the good old radio!=
How do you put your iTunes card on iTunes?
There is a Quick Links box in the top right corner of the iTunes Home page. In there is a Redeem link. Click on the Redeem link and then enter the card number into the box and click the Redeem button. Then in the top right hand corner it will have to the amount of what you bought.
Can 4 ohm speakers cause an 8 ohm amp to fail?
The amplifier will have an output impedance of around 0.04 ohms. In hi-fi we have always impedance bridging. Zout << Zin. That means the output impedance of the amplifier is much less than the input impedance of the loud speaker.
The damping factor Df = Zin / Zout tells you what Zout is.
Zout = Zin/Df.
If the damping factor Df = 200 and the loudspeaker impedance is Zin = 8 ohms, the output impedance of the amplifier is Zout = 8 / 200 = 0.04 ohms.
You see, there is no "8 ohm amplifier" on the market with a 8 ohm output impedance.
Scroll down to related links and look at "Voltage Bridging or impedance bridging - Zout < Zin".
Answer #3Actually, it's not a myth. Just a simple misunderstanding. An "8 ohm" amp does not mean it has an 8 ohm output impedance, it means the amp is designed to drive an 8 ohm load. Let me explain (warning, this is long, with math!).Let's say I want to design an amp to provide 50 watts RMS into an eight ohm load with an input of 0dbv (which is 0.775VRMS).
How much voltage and current will I need to produce 50 watts? According to Ohm's Law, P=I^2R, so:
50watts=I^2 X 8ohms
I^2 = 50 / 8 = 6.25
I = sqrt 6.25 = 2.5
We will need 2.5 amps current capacity. Now that we know amps, let's figure volts. E=IR, so:
E = 2.5 X 8 = 20
We will need 20 volts RMS.
Now, how about voltage gain? Our output is 20V, our input is 0.775V, so the necessary gain is:
20 / 0.775 = 25.8
As you can see, this amp will need to supply 2.5A and 20V with a voltage gain of about 26. The design engineer will have to build the power supply with enough voltage to reach 20V at the output, and use output transistors capable of 2.5A.
I won't write out the calculations for a 4 ohm amp, you can do them yourself just like I did above, substituting 4 for 8. If you do, you will find the amp designed for a 4 ohm load will need to supply about 3.5A and 14V, with a voltage gain of 18. Note the voltage is lower, but the current is higher!
If I design this amp for a 4 ohm load, I will need bigger output transistors (3.5A vs 2.5A), but can get away with a lower voltage power supply (14V vs 20V).
See how the design is VERY dependant on which speaker impedance I intend on driving? Now lets see the ramifications of using the "wrong" speaker on an amp.
First, let's put an 8 ohm speaker on an amp designed for a 4 ohm load. We already know from our design calcs above that the amp will be designed to supply 14V. This is less than the 20V needed to drive the 8 ohm speaker to 50 watts, so it is obvious we will not reach full power. We will only get (I = E / R) 14/8 = 1.75 amps, and therefore (P = E I) 14 X 1.75 = 24.5 watts output.
So, if we put an 8 ohm speaker on an amp designed to drive an 4 ohm load, we will get less power, in this case about half. If we try to compensate by turning up the gain or increasing the input signal, the signal will clip and distort because the power supply can't reach the required output voltage. Note that no damage occurs to the amp (although some speakers can be damaged by driving them with a clipped signal), and the setup will sound fine as long as we keep the volume low enough so that our power is less than 24.5 watts.
Ah, but what about the reverse, putting a 4 ohm speaker on an amp designed for an 8 ohm load?
Let's do this: first install a correct 8 ohm speaker on the amp, feed an audio signal in, and adjust the gain so that 50 watts is produced. We already know from our calcs that at this point the amp will be producing 20V at about 2.5A.
Now, remove the 8 ohm speaker and without changing anything else, install a 4 ohm speaker. What happens? Well, if you feed a 4 ohm speaker with 20V, what is the current drawn? I = E / R, so:
I = 20 / 4 = 5A
Oops, this is a problem. The speaker will try to draw 5A, but our output transistors are designed for only 2.5A, I see smoke!
What is the power at this level? P = I^2 R, so:
P = 5^2 X 4 = 100
Oh, another problem. Our power supply is designed for 50 watts, but we are now supplying 100! More smoke.
Now, what if we turn the gain down until the current drops to 2.5A? well, at least no more smoke, since we are no longer overloading the amp beyond it's rated limit. What will the power output be? P = I^2 R, so:
P = 2.5^2 X 4 = 25
Again, if we turn down the gain such that 25 watts or less are delivered, everything will be fine, but if we try to drive the speaker to 50 watts, we may overload the output transistors. And since this amp has higher gain (26 vs 18), and it has a higher voltage power supply, we can drive the speaker to power levels approaching 100 watts, which will certainly pop the output transistors, probably burn up the power supply, and most likely ruin the speaker too.
So, answer #1 is correct. (Yes, I am a design engineer. And, yes, I wrote answer #1...)
Answer #2 is correct as well. An 8 ohm amp does not have an output impedance of 8 ohms. It is indeed much lower. But the question asker meant an amp designed for 8 ohm speakers when he asked the question, and these definitely do exist. And using a 4 ohm speaker on such an amp can cause it to fail. Ask me how I know this... I am no stranger to smoke, believe me.
Answer #4
According to legend and conventional wisdom, solid state (transistor) amplifiers can drive higher impedances than their rating demands. So a transistor amp with a label saying "4-ohm" will drive 4, 8, and 16 ohms with no troubles. You can go up but not down. Don't try 2 ohms.
Older legends say that tube amplifiers can drive lower impedances than their rating demands. So a tube amp with a label saying "8-ohm" may drive 4 and 8 ohms. You can go down but not up. Don't try 16 ohms. And never run a tube amplifier without speakers attached. Other legends of the tube age say that any attempt to use a tube amp with speakers of different impedance may cause damage to the amplifier.
How do you sort your iTunes playlist?
1) If you are looking to change the ordering of the songs within a playlist: First you must be sure that shuffle is off. If the shuffle feature is on, you will not be able to rearrange your tracks. Once shuffle is off, simply select the song you would like to move and drag it to the desired position. A black line will serve as the indicator for the new position of the song as you drag it up or down the list.
2) if you are looking to move the songs into a playlist: If the playlist does not exist, you will have to make one first. To move songs into a playlist, you may select the songs right-click and hover over add to playlist. You may then select the playlist you would like. Alternatively, you can drag the selected songs over the playlist on the list to the left.
Hi, I am new to Wikianswers and I thought I would try and help people who are experiencing the same frustrations as I am with manipulating songs within an Itunes playlist. Previously, I have been able to move and rearrange songs freely within my playlist but after adding more songs to an existing playlist, found that I could no longer do this. I have tried all other suggestions on Google but have found that this has worked for me and may for you as well.
My Solution:
In Itunes I clicked on the sort arrow in the top left corner that contains the order number and this must have released the lock on the song order or something similar because now I can drag each song and position it wherever I want.
When right clicking on the sort arrow, untick all the sort categories, then you are free to move your tunes as you want. On a PC.
Answer
Must be in Playlist and here's the easiest way:
Click on Controls menu
Click on Shuffle
Click on Turn Off Shuffle
Then click on the song you wish to move and drag to the position you want it.
Done!
If Shuffle doesn't work, try this solution:
Ok, Turning the shuffle on/off did not work for me. The person who mentioned clicking on the sort arrow in the top left corner was on the right track but forgot to mention that it isn't in the menu. It is actually a little farther down the screen & it is the tiny little box with the up/down arrow that sits right above the track numbers in the playlist next to "Name", "Artist", Etc.
Note: Sometimes the up/down arrow disappears so you may have to click on the box in order to see the arrow. You should then be able to move the tracks anywhere you want to.
It'd be nice if Itunes would just tell us these things in the help section but I guess that would be way too easy.

How does a record player work?
Are you talking direct-driven, belt-driven, or clockwork driven (Gramophone) type of turntable, they all work differently.
A clockwork-driven Gramophone uses a spring motor to drive the turntable, that would have to be wound-up to drive the turntable. A governor kept the speed of the constant and a speed control flywheel slowed or increased the speed of the turntable. The motor has a shaft that turns and the turntable is attached to the shaft, which spins the record that rests on the turntable. The reproducer with needle picks up the vibrations that are recorded in the bumps and curves in the record groove. The vibrations travel up the needle, through the reproducer, and to a diaphragm that vibrates to produce sound travels through a tube and out the horn.
Modern Belt-drive turntables use an electric motor connected to a shaft that used a spring to turn the turntable. The Speed is changed by the motor speed either being increased or decreased. When using a ceramic cartridge, the movement of the needle back and forth in the groove bends tiny ceramic bars that produce minute electrical impulses, which are strengthened by an amplifier, which is then sent to an electromagnetic speaker. When using a "Moving-Magnetic" cartridge, the needle moving back and forth and up and down in the groove moves tiny magnets against each other producing electrical currents which are again strengthened by an amplifier and sent to speakers. When using a "Moving-Coil" cartridge, the needle compresses and retracts little springs that are attached to magnets which produce little electrical pulses, which are sent through an amplifier and to the speakers.
A direct-drive turntable works almost like a Belt-drive, but the mechanism is a little different. The motor is attached to a tiny rubber-idler wheel which is touching the shaft that turns the turntable; when the idler spins 139 times faster than the turntable. The speed of the motor never changes, the speed-change is managed by moving the idler up the shaft (Faster Speed) or down the shaft (Slower Speed). Many direct-drive turntables also have a speed adjustments that move the idler by fine amounts (usually -0.5 and +0.5 RPM).
