Signal (buzz) from mic input on Nokia N8

Hi, I'd like to record audio from the sound mixer to my Nokia N8.
So I bought reducer from 4pin to 2x 3pin 3.5mm jack (speakers + mic)
But when I connected the mix output (Main 6.3 Jack L) to the phone's mic input,
it began to buzz from loudspeaker connected to Main XLR L (these outputs on the mix are probably linked)
When I started to record or turned the music on, buzzing disappeared
So I thing it's system controlled signal for control buttons on headset
I need to have disabled it all the time while the phone is connected to the mix
Is there any way to disable it?

There's already several long threads on this forum where people are voicing their requests. You would have a better chance of being noticed if you searched and added your comments to one of the existing threads.

Is there an adaptor that can split the audio out from mic input?

I'd like to use the iPhone on a mixer borad for conferencing. I'm looking for an adaptor that will allow me to separate audio (out) from mic (in) on the iPhone. Any ideas?

Will this work for you?

Playing sound from the mic input

I'm running my turntable through a mixer and then running the line level signal into the mic input on my macbook. It sounds fine when I record the sound, but I can't seem to get it to play sound live.
I used to do this on my pc by Muting and un-Muting the mic or line-in input, but on the macbook this doesn't seem to work.
What am I doing wrong?

I guess I should add that the mixer is showing normal volume levels and when I run Audacity, the volume levels are normal. I just want to convert my input from "recording only" to playback.

Can I plug a TTL signal into the mic on my sound card?

Basically I want to trigger some LV code using an incoming 0-5 volt TTL signal.
And I was wondering if I could plug that TTL signal into my mic input and read the signal with the LabVIEW sound VIs.
But I'm unsure if I'll just end up frying my sound card.
I know I could buy a cheap NI USB DAQ board for $99 ... but I just want to get this done asap, and thought the sound card idea might work.
Any ideas?

A sound card is AC coupled. And has limited bandwidth. So I will say this is a far from optimal solution. What are you trying to do?
Sound cards are most often made for line-in signals levels. That is +/-1 volt. But this may vary from vendor to vendor.
Besides which, my opinion is that Express VIs Carthage must be destroyed deleted
(Sorry no Labview "brag list" so far)

Real Time - Capture sound signal from Mic then store to memory.

Hi people,
I wish to do a real time program that capture the data (+the ADC discrete digitized sound data+) from mic then store the data in memory...
Then my program retrieve the data continuously from the memory (as long as there are captured data from mic)
But i have no idea how JAVA deal with real time program that use memory to store the captured data.
i do know that JAVA do have class INPUTSTREAM to deal the real time thing that fetch the byte of data to program. But still wish to get more reference from here (never use this class before).
Please advise how can i start from "signal" the mic to store the captured data to memory and my program able to retrieve the data from memory then work my algorithm on it.
Or can correct me how actually i should store the captured data... i should store the data in memory or store the data as a variable?
MANY MANY MANY MANY thanks!!! Very appreciate for the advise and i will give my attempt :-).

I m sorry..
I was intend to ask the correct way to store the digitized data from microphone.
As all my previous work were storing the keyboard input as an declared variable or store in local server database.
But this time i wish to store the captured and quantized sound data from mic and no idea where should i start from...
Please give me some advise please.
I dun wish to save what i captured as a .wav file then only process the .wav file data.
But wish to process the data that was captured at instant.
I m very appreciate for your advise here.

How to get signal from analog input and send it to analog output (real-time)

Hi everyone,
I am doing simple task in Visual C++ and I am using PCI-6221(37 pin).
Basically, I want to send same signal from 'analog input' to 'analog output'
at the same time (almost), to make it real-time application.
Can someone please provide me sample program.
I would appreciate if you could provide me with the good tutorial which explains
step by step everything about programing NI-DAQmx for C/C++.
Best Regards,
Khassan
Solved!
Go to Solution.

This is my code in C++, you can optimize it if it looks too messy. This code reads signal from analog input and outputs it through analog output.
To make this code work additional include directories and library directories must be added from NI.
I hope it helps someone.

55TL515U no signal from HDMI inputs

My 55TL515U 3D TV suddenly started showing the "no signal" message from my HDMI inputs. I have a Motorola cable box on HDMI 1 and a PS3 console on HDMI 2. No other inputs are used on the TV. I can connect to the internet and can watch You Tube, Vudu, and Netflix. Both the cable box and PS3 worked fine and now cannot get signal from either one. Is there something to be reset before I call for service?

we do not have this model, but model# 65L5400U, and have had the same experience.
when going from one input to another, we would get the no signal notice and a blank screen. We could turn the tv off and back on, and it would work again.
we also started having a problem with the digital sound output (i think). we have a sound bar coming directly from the tv, and often will have no sound.
specifically when going from an HD to non HD channel, or when looking thru our cable providers on demand choices, then going back to watch TV.- turn the tv off and back on again, and the sound is back.
we have moved the cord from the tv to the cable box and do not have this problem, and hooked up another TV to test the problem, and didnt have it.
I have this TV thru a rental store, and this is the third one Ive had the same problems with.
has anyone ever spoken to Toshiba about a possible problem with this? Im running out of alternate options.

Input signal (pulse from encoder) analysis

Hi everyone,
I am using a rotary encoder to analyze the motion of a rotation shaft that is driving a piston. I want to verify that the piston's motion is consistent cycle-to-cycle and measure the frequency of rotation. My encoder outputs a Z-signal, which will pulse once per rotation, and an A-signal, which will pulse 500 times per rotation at equal distance increments around the axis of rotation.
I have looked at a number of sample VIs that analyze a waveform for dominant frequency, but those generally use a simulated waveform, and I don't know how to get the signal that I am reading into the DAQ into the correct form to analyze it this way. If I use the DAQ Assistant, my data is the blue type and I need Waveform to use the Pulse Measurements VI.
Also, if anyone has any thoughts as to the best way to verify that the rotations are consistent (I was thinking of subtracting different periods to see if the difference falls below some threshold), I would love to hear them.
I am using LabVIEW 8.5 (I know, an older version) with a PCI-6251 DAQ. I have done the 6-hour LabVIEW tutorial so I am somewhat familiar with the program, and have access to a number of VIs written by others in my lab, but they tend to be pretty complicated, and use DAQmx, which seems to require a number of different VIs.
Thanks in advance!
Meghan

unclebump, thanks for those examples. I am trying to use them as a basis for the VI I need.
Will, thanks for the offer for more help - I think I'll take you up on it!
I'm currently working with the quadratureencoderm-series.vi from the examples (the dir_encoder_corr_dig_port.vi looked much more complicated). I changed the DAQmx from Counter Input>>Position>>Angular Encoder to Counter Input>>Frequency. This should work to read the frequency of the Z-signal? (Currently my encoder is broken and I am waiting for a replacement so I can test this out).But just trying to run the vi, I get:
My I/O to the DAQmx has an option of Dev6 (my PCI-6251) ctr0 or ctr1, the only two options even when I hit Browse...so the only options it gives me are unsupported?

Get input sound level from mic

I'm trying to find out how ( if possible ) to get the input sound level from the microphone.
Example : if someone screams into the mic it would return that it is loud or on a scale of 1 to 10 it would be a 10; and the opposite if someone was whispering.
Any help would be great!
-Rob

Digital audio is stored as a series of samples, where each sample is the amplitude of the sound wave being recorded. The volume of the sound is the same as the amplitude of the sound, therefore, each individual sample is simply encoded as the volume of the sound.
So you break the mic input down into a list of samples (based on the sample size / number of channels) and keep a running average to determine the sound level.

Low signal from mic

Hi, I am new to this. I have a Lexicon Alpha and AKG D44 mic plugged into Garageband. The system works but the input signals are very low - esp. when recording an acoustic guitar. What am I doing wrong? Thanks. Alex

Assuming you are using the 1/4" inputs on the Alpha:
The 1/4 inputs on the Alpha are not made to take your mic input.
You can try a 1/4" female phone jack to XLR male plug and plug into the XLR mic jack.
Which should give you the proper input for that mic.

If you are not happy with those results then I would suggest stepping up to a decent dynamic mic like a Shure SM57.

Mic input sound port not working.....

Any thoughts?

Hi. Well - it's not actually a mic input port, it's line level.
The signal level from simple microphones is often too low for the the 'line' level analogue audio-in port on the G5.
The solution is to use either a self-powered microphone, a pre-amplifier or, possibly the most useful and flexible (and most popular) - a USB audio interface such as the 'iMic'
http://www.griffintechnology.com/products/imic/
There is some discussion and further suggestions here
http://discussions.apple.com/thread.jspa?messageID=597246#597246
and elsewhere if you enter "microphone" in the search box at top right of this forum, under 'Search Discussions'. Good Luck.

Mic input using firewire interface

I can use my AV/DV converter for imovie analog to digital conversions which has audio and video analog I/Os. Why can't I use my AV/DV interface as an audio interface to convert only the audio from analog to digital (without plugging in any video feeds)? I hooked up my mic to the preamp and then connected into the audio inputs of my AV/DV convertor and output to firewire into my mac. It doesn't show a signal or recognize the input. I know there must be something basic that I'm missing. Or am I supposed to use an audio specific interface? Please help me understand why this doesn't work. Thanks!

Did you mean the Behringer Xenyx 502?
Yes
- this could be connected to the line in, but it doesn't have USB.
Yes
Wouldn't the Fast Track be a better bet?
Mostly I was considering price, the 502 is half the price of the Fast Track ... $45 is often a bit easier to swallow then close to $100.
I also question the "Quality" term that gets tossed around a lot. One would assume that the FT should offer higher quality A/D converters then the stock Line-In, however I still believe that the way one records and mixes is more important to getting a good recording.
I don't think either choice would be a mistake in the end. ~~Hang

Do webcams work with a MacPro? and which mic input?

I have bought a new Mac pro 2 days ago and a web camera: Extreme Webcam SN9C201.
I see a clear and fluid image but there are many video artifacts, like great green and purple pixells, arising from the low part of the image to the center.
Any tip?
I have 2 MOTU audio interfaces. I want to use skype without using the MOTUs.
It looks like the analogic input in the Mac-pro is only for line signal.
So what is the cheapest and easiest way to get some microphone preamplification?
Maybe the Griffin Technologies iMic?
Grazie
Sergio

Hi Sergio,
I have a Logitech QickCam UltraVision and have never noticed any video artifacts. It works fine with iChat and Photo Booth. It has a built in mic but it has been a while since I used the mic portion and don't remember if OS 10.5.1 recognizes it. I will hafta test it.
As far as additional mic inputs go, the Griffin iMic has worked for me in the past on an older G4 PowerMac (don't have the iMic anymore to test it on my Mac Pro). I now use a Plantronics mic/headset combo that plugs into a USB device (similar in size to a USB flash drive) which I then plug into any USB port on the Mac. The headset works great on the Mac side as well as on my Vista partition. Both OSs have no difficulty recognizing the USB headset.
Hope this helps.

External mic inputs and speaker outputs for CP-7937G Conf Phone

Has any tried to connect the Polycom® SoundStation IP Multi-Interface to the Cisco Conference Station CP-7937G Phone, it appears to be the only way to get eextra mic inputs and line level outputs for enhancing conference call? See attached Quick Start Guide.

Here's where I am on interfacing external mikes, PCs, speakers, etc. with the Cisco 7937. It seems this I/O port is quite a mystery to both Cisco and the manufacturer (Polycom). There are virtually no technical specs for it anywhere on line. So, I bought a variety of cables and connectors and tried exploring. I could never get anything but input into the 7937 to work. I could never get any output from it despite the output symbol next to the port. Here are the input test results:
3 pole 2.5mm to dual stereo 3.5mm breakout cable didn't work at all
4 pole 2.5mm to stereo 3.5mm for input worked only on one pole (red connection). Half volume?
3 pole 2.5mm to stereo 3.5mm for input works only on white connector (louder?)
3 pole 2.5mm to mono 3.5mm for input, works (louder?)
2 pole 2.5mm to stereo 3.5mm for input, works
2 pole 2.5mm to mono 3.5mm for input ,works, and is simplest.
So, if you want to feed an external audio source into the Cisco 7937, almost any type of 2.5mm male connector cable at the 7937 will work
I could never find any mention of successful use online, and could not find an output signal myself, so I suspect the 7937 was just mislabeled.
