Is there a mac progrom that will reduce ambient noise from the line-in?

With this type of connection, there should be no opportunity for ambient noise to be introduced. Are you getting some type of line "hiss" or "hum"? I am not aware of any software application that will provide real-time, ambient noise suppression.

This is a hardware issue. Any noise suppression equipment would be studio level devices, much more expensive then the cost to purchase the right type of consumer electronics to avoid this type of set-up. You can make this work with less noise, but understand that the set-up you are using is less than ideal; it's just not made to work in this manner.

Try this... Make certain that your cables are as short as possible and that they are routed away from any high voltage AC wires (to avoid them picking up the 60 Hz hum through impedance). Also keep the cables are away from any fluorescent light fixtures and cell phones (stray noise from signals at even higher frequencies). Make certain that the cable connectors are as clean as possible; wipe them down with a clean cotton cloth / cotton swab with rubbing alcohol if necessary.

I assume that you are using the regular headphone output from the Zune. This is not an ideal signal to apply to the line-in on the Mac, as the impedance does not match and the signal level is likely too high. For the best possible result, you should make certain that the volume control on the Zune is set relatively low, and then rely on the amplifier in the Mac to adjust the output level for your speakers.

If the Zune volume control is too high, the signal will over-drive the input on the Mac's audio amplifier and introduce a lot of noise and distortion. Again, the set-up you are using is not intended to work in this manner. Just because you happen to have a cable that connects the Zune's headphone jack to the Mac's line-in doesn't mean it's supposed to be used in this way.

The line-in signal is intended to come from a pre-amp source like a mixing board. The "ambient" noise that you have may be the best that you can hope for.Sorry.

There are pre-production ways and post-production.... Pre-production, there isn't any program that I can think of, but you can do a number of things to reduce ambient noise. If you have an external mic, using a windsock (the foamy thing that sticks on the end of the mic) helps. I've also made a portable sound proof cube to surround my mic and the front of my face.

I've heard that Leo Laporte used to crawl under some blankets to make a (very hot) sound proof area. Post-production, most software has sound reduction. In GarageBand, if you select a track, make sure you're viewing Track Info (click on the "i" in a circle on the lower right side of the screen), and then click on an empty box ("Click here to add effect").

Select "Speech Enhancer". Click on it, make sure it's "on" and use the "Reduce Noise" slider to your hearts content. Other programs have post-production noise reduction as well...

Virtins Pocket Signal Generator 1.0 that consists of signal generator and an off-line oscilloscope. It provides the following types of waveform for output: (1) Sine (2) Square (3) Triangle (4) Saw Tooth (5) White Noise (6) Pink Noise (7) Multi-tones (8) Arbitrary via user-configurable waveform library, at either a fixed frequency, or a frequency that sweeps linearly or logarithmically within specified frequency range and time duration.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
