Hi,
I wonder if it is possible to use a computer by plugging a mike and seekers into it, and then use it as a public address system.
Example: using a slide show and have your voice come through the speakers.
Or when playing music to sing along through the speakers. If there is a program or a way to do this I appreciate it if you let me know.

Yes, but I would question the prudence of such a setup for any environment larger than a room. Most computers with audio hardware have connections for microphones and speakers. However, for a large presentation environment such as an auditorium, amplified speakers beyond the scope of typical desktop computer speakers would be required, in which case the microphone could be plugged directly into a multiple input speaker amp. Personally, I would go with a discrete projector for the slides and a separate PA speaker system/amp for the laptop's audio output, a non-computer mic, and possibly a small mixer. You can also get Karaoke-in-a-Box devices with amp, speaker, tone/volume controls all in one easy to transport box. The folks in the Electronics forum may have additional suggestions.

It is not intended for a large auditorium.
The intent is to address about 30 people in a room.

Give it a try. Hook up some speakers and mic to your laptop and see if your setup is up to the task by doing a dry run of your presentation in the actual room or a similar environment.

No that does not work

This is a tough one... I'm sure there may be some software out there (audio mixing software to be exact or perhaps karaoke software)... though I am not sure.

It seems that using a laptop as a mixer comes down to finding software that will let you do it.

Question: Are you putting together a presentation and/or providing some sort of entertainment? Just wanted to get more details to see if I could offer any more help.

The Idea is to use it in a meeting. I am looking at the laptop at some slides about business at hand. (about 15 slides) I would like a speaker to carry my voice or the voice of the lady sitting bside me. She is verry soft spoken, it is most for her.

Thanks for your response.

I do not have a good, solid answer for you, except what I offered in my previous post.

I hesitate to even post the following but here it goes: Is a "Mr. Microphone" with a small boom box nearby too "cheesy"/unprofessional?

I'm not trying to be funny or cute... just trying to "think outside of the box". I am sure you understand.

Best regards.

I assume now that it can not be done, I was hoping that there is a plug in for Windows Media Player

Specifically, what did not work when you tried? Nothing additional is required. You can hook up a mic and speakers and using Windows? Built-in volume control crank up the volume. You may need to un-mute the mic or enable any gain boost setting in the advanced options for your audio hardware for the mic volume to be loud enough. Also, depending on your laptop's audio specifics, the audio output may need to be switched from internal speakers to external jack, etc.

You can use the open-source Audacity program to simultaneously record and transmit the presentation. You will need to check sound levels for feedback, however.

Another option would be to have the presenter record the audio for each slide, then insert the audio into the presentation.

If you have a set of PC speakers, you can use a 3.5mm coupler (Amazon.com: Cables To Go - 03170 - 3.5mm Stereo Coupler F/F: Electronics (http://www.amazon.com/Cables-Go-03170-Stereo-Coupler/dp/B00007FGUF/ref=pd_bbs_3?ie=UTF8&s=electronics&qid=1221614112&sr=8-3)) to connect the speakers to a handheld or lapel microphone directly (using the correct plug adapter) and bypass the computer completely.

Use Your PC as a PA

I need to send audio input from a microphone to my PC's speakers. Essentially, I want to use my PC as a small-room public-address system. Can I use my sound card direct from the microphone?

Not only is this possible, it's surprisingly easy. We'll assume that you are running Windows XP, but the steps are similar for other versions of Windows. We will also assume that you have a microphone plugged into the microphone input on your computer's sound card and that the mic is switched on, if it has a power switch.
Find the speaker icon in the system tray. If you don't see a speaker icon, launch Control Panel and double-click the Multimedia, Sounds and Multimedia or Sounds and Audio devices applet. On the first tab find the check box that relates to showing a volume icon on the taskbar - check that box and click OK. Double-click the speaker icon to open the Volume Control window, which acts as amixer board for the various sound channels. In that window, choose Properties from the Options menu. Make sure that Playback is selected in the Adjust volume for box,and that the check box for Microphone is checked in the list of volume controls. Choose OK to close the Properties window.
You should now see a column labeled Microphone in the volume controls. Uncheck the Mute check box for the microphone, making your mic live. Adjust the Microphone and Volume Control settings and the volume control on your speaker system as needed.
Depending on how you have the speakers and microphone positioned, you may experience feedback problems. This is caused by sounds from the speakers entering the microphone, getting amplified, and then coming out of the speakers again. This loop creates the familiar screeches and squeals associated with microphone use. You may be able to defeat them by using a directional microphone, but if all else fails, position the microphone behind the speakers.
