i am using stero headphones with mic attached with it

Is that USB?

Edit menu > Preferences > Audio I/O
"Play other tracks while recording new one" = ON
"Software Playthrough" = OFF - If this is on it could be the cause of the problem.

You may be able to configure your microphone to play through your headphones through the Windows Control Panel - it depends on the drivers.

I'm having some difficulty understanding exactly what you mean.
Can you try to describe what you mean by "there is a gap between track voice and my voice".
Do you mean that the there is a delay between one track and the other? Are the two tracks out of synchronisation? If so, how much out are they and is it a constant amount? Can it be fixed by dragging one track left/right with the Time Shift tool (double headed arrow)?

gap means that when i tried to sing with the kareokee track it seems evrything is goign fine but when i listen the recorded stuff it seems to me that i am going out of beat u understand means there is a difference that mic roecords my voice....what i think is the difference of less less than a second...
why its happening i havet used that time shift tool.how to use ot

[kozikowski]

The TIme Shift Tool is the button with two black arrows on it, left and right. Select the track you wish to shift and press that button. You can click and drag the sound track to the new location.

This error is not serious. Audacity 1.3 has latency controls in Preferences that you can adjust to make this problem go away -- or become very much less serious.

yes it solved my problem
i need another help where could i learn to know the use of proper sound effects and their values its critical in points like1.33300 etc difficult to understand which value to chose.also the frequency and about project rate what that term mean....
thx in advance...

Digital sound is usually described in three numbers, like 44100, 16-bit, Stereo. That's the specification of Music CD audio.The first number, sample rate is the fineness of breaking sound up into digital numbers. That generally affects whether or not you have clear, sparkling sound.

The second, bit depth is the size of the digital numbers in your digital sound. That number can affect how quiet or loud the sound can get. Third is the number of sound channels, two in the case of stereo.

You would think that you would want the maximum number in each of the values for best possible quality, but the music digital size goes up when you do that and if you go crazy with large numbers, you'll only be able to fit three songs on your iPod or music player.

The numbers can also change depending on your job. If your job is to listen to music, then CD audio is fine. If your job is to apply filters and perform special effects on the music, then higher values may be needed. Low digital values get damaged easier than high ones.

Most people can't tell quality changes in digital sound values higher than Music CD.
