What does a low pass filter do to audio signals? I know what is a low pass filter but it confuses me when it is applied to audio signals.

How do you delay ANALOG audio signals. I am trying to delay audio signals from a microphone array.? I am trying to delay audio signals from a microphone array.(there are 4-5 different outputs from the array of 4-5 mics, so I m trying to delay each of them for beamforming).

Can a audio splitter instead converge separate audio signals.? Normally, a 1/8 inch audio splitter will split the audio. Instead, will the audio splitter converge two separate audio signals if setup backwards? Is there a better way to converge audio signals from two separate sources?

Can I convert SPDIF digital audio signals to analog RCA outputs? I have a home theatre scenario where I have component video and SPDIF audio delivered to a room. I'd like to be able to connect the SPDIF digital audio to the good old "stereo RCA" inputs of the TV. To do so I need a small, cheap box that will take SPDIF digital in and produce either analog stereo or analog surround signals. I'd think this would be easy, but can't find anything besides this, and I'm not even sure if that does it: http://www.amabilidade2002.com/toslink.htm So... SPDIF in, left and right analog RCA cables out. Anyone know of a solution? Thanks! By the way, yes I understand this downgrades audio. Its just for watching the news and stuff where you don't want it run through the whole surround setup, or where the room doesn't have a receiver. Still looking for a small simple "DAC in a BOX" to do this...

What audio signals are output by the center channel speaker in a home theater system? The reason I'm asking, is that I'm not sure if mine is working. Theres some static, but no real audio. I'm sure it's wired correctly. Will it only pass a certain frequency band at certain times, like other surround sound speakers or a sub? Is that why I'm not hearing anything when I check?

What do I use to combine 2 audio signals into 1 set of speakers? I tried a Y adapter but one source is always interrupted. Is there some kind of thing I need to get to combine the 2 audio outputs?

What's the best way to send analog audio signals over longer distances than stereo patch cables? I want to send my computer's audio output to the stereo in the next room (about 25 ft). If I used a super long audio cable, I assume the signal would degrade too much. Is there a device that converts the audio to another format (e.g. Ethernet), then back to audio at the other end? Or how else could I accomplish this?

On aircraft, what do the audio signals to cabin crew mean? When you're in an aeroplane, there are "bing"s, "bong"s, and "bing-bong"s for the benefit of the cabin crew. What do they mean? Are there any other signals used for the cabin crew?

Hi. My question is regarding types of coax that can be used to carry digital audio signals.? Basically I am building a new house and am setting up 2 audio systems for 2 locations within the house. I want to try and make use of digital audio outs from my computer and some other sources so I am runnig cables to suit. The distances aren't great probably 10 to 20 metres. It doesn't seem possible and certainly not economical to buy ready made digital audio coax cables to suit. I actually work in the surveillance industry and use alot of RG59bu coax cable for video signals. It is more flexible than the standard RG6 used for TV transmission. Can I just use this cable and fit gold plated RCA connectors at each end? It is 75 ohm, which seems to be listed on all the specs for ready made cables. Or is there a specific type I must use? Also are those distances an issue? I would appreciate some advice. Thanks

How do I remedy the numerous interruptions in my launchcast audio signals, this menace called buffering?

Unbalanced and balanced audio signals? In an unbalanced cable, what is it that causes interference? I get the basic idea about balanced cables sending the same signal "out of phase" in different directions and cancelling each other out at the other end which would be a mixing desk or a guitar amp etc. But if anyone knows of any sites or could explain unbalanced and balanced audio cables/signals to me that would be fantastic. Cheers guys!

HDMI is giving no video or audio signals? I plogged in my HDMI cable, and BAM!!! No video or audio. I turn my 360 on, and nothing shows up on my T.V. it used to work before, but now it doesn't. Also, the cables going to my surround sound also do not work. Help!

Can you reduce the audio signal from a cd player to an amplifier with an in line connector? When I play a disc on my cd player at low volumes the output is either too high or nothing. I thought that if I could put an attenuator connector in line to reduce the input signal this might give me better control. I know you can do this with tv signals and rf cable but is it possible with audio cable and phono connections?

Audio splitter cable needed, taking 2 audio signals and feeding them into the same connection on my TV? I have a new HD TV that uses the same Audio input for Composite and for the VGA display options. I need to find a cable that will allow me to permanently plug in audio cables from my Media center PC and my Xbox 360 at the same time. I will only be using 1 at a time so interference shouldn't be a problem but the only audio splitter cables I can find take 1 source and split it into 2 rather than the other way around. Any links/thoughts on this? Bearing in mind I need UK or ship to UK websites. Thanks in advance

Is it possible to transmit a wireless audio signal from my computer to portable radios elsewhere in my house? I frequently listen to internet radio. This can be linked up by audio sender from the dining room computer to the aux socket on the lounge HiFi, and could also possibly be heard elsewhere in the house by purchasing dedicated internet radio receivers utilising our wireless broadband connection. It would therfore appear to be far more cost effective and less restricting if this signal could instead be transmitted via FM in some way to my existing portable radios. Is it possible to utilise and adapt the new MP3/FM car transmitters for this purpose, or is there some other simple means of achieving this?

how can I boost the signal coming from my computer to the amp (audio signal booster)? I am using a stereo to rca cable to go from my computer to the amp and need the audio from my computer to gain a few db's, is there such a thing as an rca cable in line signal amplifier?

How To Split Subwoofer/Center Output from Audio Card To Separate Subwoofer & Center Signals For Yamaha Amp? My audio card has 3 micro output plugs: 1/ Frt Speakers 2/ Rear Speakers 3/ Combined Subwoofer/Center output I'm able to split frt and rear signals with a RCA y-adapter to get frt-left frt-right and rear-left and rear-right. Do I use the same y-adapter to separate subwoofer from center signals I already have the sound card. It has 5 outputs. front-right, front-left, rear-right, rear-left (which are split from the 2 y-adapters) and the 5th is labelled center/subwoofer. Can I split that with a y-adpater as well?

Is there a way for computers to receive walkie-talkie radio signals? Can you either buy a receiver for a computer to pick up walkie-talkie signals, or somehow pick them up with some type of Wi-Fi-enabled device? I want the walkie-talkie air wave audio signals to show up as an audio input device on my computer so I can record and broadcast them, etc. Is there a way to do this on either a PC or Mac?

Is it possible to convert DC Current into an audio signal? I realize that DC current does not alternate and therefore technically would not create any sound, but all I need is an audio representation of the amount of DC current flowing to a motor. Sort of like voltmeter that provides sound instead of a number for its readings. I have looked into using a DC current converter to power a tone oscillator, but the project seemed a little too complex for me. If any one has any ideas, or even knows of a multimeter that has an audio output, please let me know! Thanks! I have limited electronics knowledge... I built a few VERY simple circuits (Blinking LED's, etc) in high school, but I don't have the same resources now that I did then. The purpose of this conversion is to turn the signal sent from a video game to the "rumble" motor in the controller (basically DC current to an electric motor) into sound that can be fed to a device called a Buttkicker LFE (www.thebuttkicker.com), which is basically a vibrating motor that is activated by low end (bass) frequencies. I would definately use some sort of IC chip in a cirucuit if I knew how, but most of the instructions for voltage to frequency converters seem way over my head.

How to control the volume when I output the audio? Dear all, I have a Samsung LN40A550 1080p LCD HDTV. However, the TV speaker is not good as I expect. So I mute the TV speakers and connect the audio output with external speakers. The problem is that I cannot use the TV remote control to adjust the level of the volume anymore. It seems that the TV remote volume control only works for the TV speakers rather than the output audio signal. Anyone gets some ideas? Thank you -Daniel To Golfer: Manual: http://downloadcenter.samsung.com/content/UM/200803/20080307202315171_BN68-01392A-00L02-0221.pdf I am not able to find the menu that can set the output audio as viabled. If possible, may you help me see where it says that? I do find the place where I can turn off the speaker. thank you for this:) Thank you -Daniel

Is it a Michigan Law that you have to give an audio signal when passing on a 4 lane highway? The state police said I was partially at fault, when I smashed into a car making a quick left turn, with no signal, from the right lane of a 4 lane highway.

Can I silence HDMI Audio in my Sony DVD Changer? I'm my current home theater setup, I've got my Sony DVD Changer (Model DVPNC85H) with an HDMI output to my Bravia TV, and a Digital Coaxial Output to my A/V Receiver. I prefer to have my audio routed thought the Receiver at all times, but the HDMI carries an audio signal to the TV as well. I'm looking to find a way to mute the HDMI audio stream from the DVD Player to the TV. The only HDMI audio options on the DVD setup are "AUTO" and "PCM", unless I'm missing something. If I mute the TV, I have a "Muting" dialog box in the corner of the screen at all time, which Sony has confirmed that I can't remove. In the short term, I'm able to manually drop the volume on the TV, but I'd prefer to have all of this programmed through my Harmony remote without having to fuss with the volume levels manually. Any thoughts on muting the HDMI audio stream? New detail to add re: the first response... My AV Receiver is a few years old, and has no HDMI input.

How can I get my Vizio 42" with optical out to send audio signal to the surround sound receiver.?
