Feedback from microphone recording

how to eliminate excessive feedback when recording from the microphone in jack??

It's called "feedback". Just like your ears can hear the
speakers, the microphone also hears the speakers. Imagine this: The
mic picks up your voice, computer plays it out on the speakers,
which the mic also picks up and plays back along with the original
voice sound from your mouth; both sounds combined play back through
the speakers...which the mic picks up, and so on. It's called a
feedback loop.
Best solution: wear headphones.

  • Stray feedback from microphone

    Hi!
    I have big problems with sound in Flash, exactly it's related
    to stray feedback betwen microphone and speaker. How to avoid it
    (moving both of them to the more big distance is not a solution,
    because a laptop)?
    When I try to record audio I can hear sound with quite big
    noise. But if I go to Flash movie menu and reduce echo or change
    record volume (i. e. really changing any parameters) the sound
    becomes better, i. e. noise, not finally, but decreased. But when I
    load Flash movie at the next time I can hear noise again (even if
    params were saved before), until next adjustment.
    Could somebody help me how to solve this problem - any idea
    is appreciated?
    Thanx

  • Silent feedback from microphone after pressing the record ready and or input monitoring buttons

    Hi Community,
    So I am running a microphone(xlr cable)-->mbox mini--->macbook and have been able to successfully record many songs in the past. Just recently I have run into an intersting issue which I hope someone can provide a solution to.
    When I hit the ready record button or the input monitoring button my level automatically shoots up about a third the volume bar without me even singing into the mic (My monitors are muted and I am wearing headphones). After recording, the wavform looks like there is a thick bar on the top half. I can still hear vocals but they are very faint, unlike how i used to get a clear, quality sounding recording. My input on the interface is also at about halfway and my phantom power is on.   Here are some pictures to give you a better understanding of what I am looking at.
    I hope this is clear
    If ANYONE has a solution to this issue please let me know
    -J

    Trying another interface is probably the next step. I would also make sure the Mic is ok, do you know anyone with an interface or mixing board that supplies phantom power? Make sure your cables are good, a shorted mic cable can blow an interface op-amp in less than a second.  The Mini may have blown on it's own, as I recall the mBox series did have some problems along those lines.
    The general rule with phantom power is, do not plug (or unplug) any device with it on, this holds true for the interface into the computer or to XLR->Mic / XLR->Interface.  After turning off phantom power I usually wait at least 15-30 seconds to let voltage drain from the circuits before starting to remove cables...etc.
    As you can tell, I'm on the cautious side when it comes to phantom power and mics/mixing boards, I worked at a studio that had mics valued at $5,000 - $10,000 and a mix board that cost far beyond that... always play it safe.

  • HELP!! Audio not playing from microphone recording.

    Ok so i have a stop frame animation and have recorded audio for it using the built in microphone, i opened it up today and only 2 pieces of the audio are playing and the others are not. I need help quickly as it is in for tomorrow. When I show wavelengths there is nothing in the ones that are not playing.

  • How to decode PCM from microphone?

    I need to make clap recognition on iPhone.

    I have an idea to replace AudioFileWritePackets in callback AudioInputCallback. And that inBuffer->mAudioDataByteSize bites from pointer inBuffer->mAudioData will be amplitude-time signal representation... But I do not know how to decode that memory area: looks like I need to work with a pairs of bites (mBytesPerPacket = 2). May I represent them as one of "standart" types (like int)? Is it signed or not?

  • Webcam Video pauses when recording sound from microphone

    I have a strange problem which i am encountering when recording and playing back webcam video.
    I am developing a small application for recording webcam video and audio using FMS and playing it back later from FMS.
    I am using AS 3.0, FMS 3.5 and flash CS 5.5
    When i record only the video from webcam without sound from microphone the playback is fine. But when i record microphone sound also along with the video, and when i playback the video pauses right where the sound starts for 10 sec or more and then it starts playing. Towards the end the video pauses again and only the sound goes on till the end.
    I tried setting the buffertime to 50 before ns.publish and ns.play but that didnt help either.
    I tried using the flvplayback component and even their it pauses.
    Any help is appreciated.

    Haha, that is such a genius use of common sense! Thank you, I didn't think of that. I certainly will!
    However, does anyone know if there is a way of adjusting the program of garageband to fix this issue? Using headphones certainly fixes the symptoms of my problem, but it doesn't actually address the root cause: garageband should only be recording the input through the microphone. I shouldn't need to wear headphones. (And doing so inhibits my ability to clearly hear myself play, and stay in tune.)

  • Playing sound from microphone on speakers (through buffer) with constant delay

    Hi,
    I'm looking for an example of code that samples signal from microphone and
    plays it on speakers. I need a solution that has a resonably constant delay on
    different platforms (PC, android, iphone). Delay around 1-2 s is ok for me, and I don't
    mind if it varies everytime the application starts.
    I tried using SampleDataEvent.SAMPLE_DATA event on Sound and Microphpne classess.
    One event would put data into buffer the other would read data.
    But it seems impossible to provide constant delay, either the delay grows constantly or
    it gets lower to the point where I have less than 2048 samples to put out and Sound class stops
    generating SampleDataEvent.SAMPLE_DATA events.
    I wan't to process each incoming frame so using setLoopBack(true) is not an option.
    ps This is more a problem on Android devices than on PC. Althought when I start to resize application
    window on PC delay starts to grow also.
    Please help.

    Most recording applications have a passthrough option so you can listen as you record. It is off by default to avoid feedback if you are using a microphone.

  • Value from info record in work order

    Hi,
    We have created some info record.While creating some work orders we enter info record number in peration-external tab-price field. If in some earlier order info update is tick while creating purchase order having this info record then in new work order -operations tab-external tab-price field rate is picked up from purchase order history and not from value maintained in info record (ME11/12) manually.
    Is their any setting / SAP note so that all the times rate will be picked up from info record (ME11/ME12) and not from purchase order history or info update.

    On Creative Surround Mixer (SM)(or on Windows Sounds and Multimedia settings panels (WS), how have you set
    - "Recording Without Monitoring"? Can be set through '+' sign above .REC slider on (SM) and behind Advanced button on (WS) Play Control)
    and have you set
    - .REC to other then "What U Hear" (AnalogMix(), or something else)? Can be set on .REC slider control (press icon above slider) on (SM) and behind Advanced button on (WS) Recording Control

  • Audio from Microphone Repeats - No External Speakers

    This one is a little odd.
    We are getting an echoing - but not from open mics /
    speakers. It's like the audio is being re-routed into other audio
    streams and we have no idea why. I'm working through the soundmax
    drivers now.
    I'm unable to get any consistent points to determine what is
    happening, but it is not speakers / open mics.
    Has anyone else had an echoing - more of a repeating - from
    microphones?
    TIA, I've found nothing from my web searches yet.
    -SR

    The sound / audio set up for the computers with this issue had the recording properties enabled within the audio settings - effectively re-broadcasting all of the other User's microphones within the session.

  • T60 soundmax built in microphone records all the time, again! Vista

    When using Audacity 1.2.6 and source set to "stereo mix", the soundmax drivers are again constantly mixing the microphone into the streaming audio, or other sound playback, such as VLC playing an .mp3 file.
    When using Audacity 1.3.13 there is no "stereo mix" option to choose from, and again microphone is always recording when recording streaming media or other sound playback.
    Using microsoft update this last week, for some reason microsoft has removed the 2009 update which corrected this problem.  Microsoft update says the 2007 drivers are now the latest soundmax drivers for my computer, and has changed them back.
    I can't roll back or forward to the 2009 update.  I did not do any manual changes, all updates from microsoft are set to automatic.
    Audacity only uses the system drivers, this is not their programs fault, this is a driver fault between vista and soundmax
    please fix ASAP as my compute is now useless to me until its fixed!
    BTW turning on stereo mix from Vista did not fix the probem, the microphone records even under selecting the input to CD.   If I mute the microphone, then there is no sound input under any input setting.

    hey midnightvisions,
    uninstall the current audio drivers that you have. let windows install its generic drivers.
    then test with audacity and see if you're able to use it as how it should be.
    later on, visit http://support.lenovo.com and update your audio drivers accordingly

  • Audio Feedback from Keys

    For some reason I get audio feedback from any keyboard input while in Stickies. Only happens in stickies and Notes under the dashboad, as well.
    It's not the keys themselves, it's actually coming from my powerbook, like a tiny tick sound, but definately not a mechanical sound; it's distinctively electronically generated.
    It's hard to tell if it's coming from the speakers or not, and changing the system volume does nothing.
    I've checked settings under Universal Access and every feature is off. There are no settings under Stickies or the Dashboard for any kind of audio feedback feature.
    Weird.
    Anyone else notice this?

    Can you try an external microphone (connect via USB), and see if same issue occurs?  If the problem persists, then you might want to check hp.com to see if there is a newer audio driver for your model.

  • After using the internal mic for the first time I am getting a buzzing feedback from my audio output

    After using the internal mic for the first time I am getting a buzzing feedback from my audio output

    Go to System Preferences Sound Input and adjust the volume level down by dragging the slider to the left. With an audio app like Logic there is an option for input monitoring when recording so there might be a feedback loop if the volume is set too high. Garage Band works in a similar way. Always be careful when using headphones as the noise can be frightful and cause hearing damage. 

  • Feedback from virtual guitar amps

    Hello,
    I'm a new Logic user and also new to recording. I've been getting bad feedback from the virtual guitar amps on the distortion channels. Almost like when playing through a real amp with tons of gain and sitting right in front of the amp. Just curious if there's anyway to reduce this, as I still get the same feedback on these channels even when rolling back the gain. I've had NO problems with the clean channels whatsoever. Thanks for any advice!
    Jordan

    The headphones are emitting the feedback. I have them plugged into the jack. They don't feed back on any other devices that I use them with. I think it might be a problem with the hardware. I'm going to go get it checked out this week. I appreciate your assistance though. It was helpful.

  • DPS Feedback From Client: A Book Publisher's Perspective

    Greetings,
    I thought it might be helpful to both Adobe and other publishers to post some real-world feedback from one of our clients.
    But first, some background:
    We are a book publisher moving into the realm of book apps. Our book apps or not at all like their printed counterparts and mix in a bunch of new content and interactive features. Our apps are also not like magazines, which is what DPS feels like it was designed for.
    We've been doing some testing with DPS, especially as it relates to a business model for us and our clients. We've also been testing resolutions, and figuring out the differences between single-issue and multi-issue apps.
    I posted an overview of where our tests led us in terms of single vs. multi, here:
    http://forums.adobe.com/message/4333151#4333151
    and I posted some resolutions tests to see if an iPad 1/2 resolution app would look "good enough" on an iPad 3 (or the new iPad), here:
    http://forums.adobe.com/message/4333426#4333426
    and finally an overview of what we hope Adobe will do with single-issue apps and renditions, here:
    http://forums.adobe.com/message/4333494#4333494
    Below is a continuation of our DPS discovery process. At the same time we are exploring HTML5/CSS3/Javascript development with Baker. Although we've developed our own webapps, run everything in Amazon's cloud (ec2, s3) and have a development team familiar with everything needed to get a book app out via HTML, we are giving DPS a fair shot because we've invested so much money in Adobe's software and we'd rather our production team handle book apps instead of our development team.
    With all of that said as a backdrop, we presented an interested client with the option of publishing two single-issue apps (iPad 1/2 and iPad 3) or publishing one multi-issue app.
    Pricing wise, we kept our design fees the same with either option. The only pricing difference was $395x2 for the single-issue app route vs. a monthly charge to help us offset Adobe's monthly charge for the multi-issue app.
    The questions from the client and answers from us went like this, in roughly this order:
    Q: With the single-issue app, we don't pay an ongoing monthly fee?
    A: Correct. It's just the up-front per-app fee.
    Q: And in the multi-issue app arrangement, it doesn't matter how little our sales trickle in 6-9 months down the line, we're still paying the monthly fee if we want to have the app for sale at all?
    A: Yes.
    Q: Does either option limit us in terms of how long the app will be available for download?
    A: No. Both options allow for ongoing sales of the app. The primary difference being you pay monthly to keep the app "alive" for multi-issue apps whereas single-issue apps live indefinitely with no monthly cost.
    Q: So it seems like single-issue apps are the way for us.
    A: From a pricing standpoint alone, yes, because most of your app sales will occur in the first month or two and single-issue apps do not carry any monthly costs down the line. That said, single-issue apps have some serious limitations.
    Q: Like?
    A: For starters, we would have to develop two apps to target iPad 1/2 and iPad 3.
    Q: So the customer would have to make the choice? We are expecting the customer to get  technical and figure out which app is for their device?
    A: Yes. Renditions only exist in multi-issue apps, currently.
    Q: Let's suppose we can get over that because eventually we will want to develop an Android version and a Kindle Fire version and in that case we are expecting customers to know which app works on their device...
    A: Let me stop you there. Single-issue apps only work for iPad.
    Q: So if we go the single-issue route, we simply can't ever develop an Android or Kindle Fire app?
    A: Not as a single-issue app for any other platform than iPad. If it was essential you release on other platforms, we could look into converting the single-issue app into a multi-issue app later on, although we'd be looking at that monthly charge again.
    Q: Right, which simply doesn't make sense for our app because of its timely nature.
    A: We agree. Let's give up developing for other platforms for now and even indefinitely and focus in on just the iPad single-issue app development.
    Q: Okay. So we release two apps, one for iPad 1/2 and one for iPad 3 using single-issue apps. What if we want to update the app down the road? Do we update both apps at once?
    A: Actually, with single-issue apps, you can't update the app. Once it's submitted to Apple, it's locked in once and for all. Only multi-issue apps can be updated.
    Q: That's another serious issue for us. Are there any other limitations we haven't discussed?
    A: There are two more limitations: 1) Single-issue apps rely on the latest version of Adobe Content Viewer approved by Apple. Currently, version 19 of Adobe's DPS tools work with the Adobe Content Viewer that's approved and live in the App Store. That means we can develop your app using v19 of Adobe's tools but will have to hold off on updating to v20. This isn't so much a real issue as a potential issue. If, for example, v20 has some killer feature you really want to have, we simply couldn't use it. 2) Single-issue apps have no analytics.
    Q: With all of these limitations, we're going to have to discuss internally which way to go. What's your recommendation?
    A: All things considered, we think single-issue apps is the best solution now for your app. We have no exact target sales numbers in mind, but it's almost a certainty you will sell 80% of all app sales in the first 1-2 months. Knowing you want to keep the app available indefinitely means a single-issue app is the only way to go.
    After two days and a few conference calls, the client decided to move forward with two single-issue apps, although a bit begrudgingly. We didn't pull any punches and let them know we expect Adobe to spend some time refining their pricing strategy and unifying the feature set as the technology starts to grow up. At this point, the seemingly wonky pricing structure and feature parity is the cost of being on the bleeding edge.
    And we are now jumping into developing the app with DPS for our client. I should say, however, we are also working quickly to come up with a viable HTML5 route for publishing to avoid Adobe's system altogether. At this point I anticipate we will move to HTML in the next 2-5 months if Adobe's pricing/features don't start to move toward what we need. If we do jump to HTML, the answer to most clients' questions will be, "we can do that; for cheap; on all devices" and so on, which is a pretty attractive thing.
    This ended up being considerably longer than I had originally envisioned, but my hope is it is useful for Adobe in refining the product and helpful for other publishers just starting down the DPS path.
    Thanks,
    Chris

    Alistair,
    Agreed. It wouldn't be right for us to pass on Adobe DPS' entire monthly charge to one client, and we have no plans to do so. We are still fine tuning the amount we would pass on to each client.
    From our perspective, we are hesitant to invest anything at all in the multi-issue route because other paths to digital publishing/apps are looking more and more attractive. If we put out a handful of DPS multi-issue apps now (say, 4-5) then jump to HTML in 3-6 months, we will have to maintain Adobe's monthly fee indefinitely for the first 4-5 apps. It's as if we are paying Adobe for the right to be locked into paying Adobe monthly. No thanks.
    From the client's perspective, even if the monthly amount we pass on is minimal, simple math shows at some point monthly sales will not cover the monthly carrying cost. When that point comes is pretty crucial to figure out, but it's likely it will come in month 2 or 3, which means the client would be forced to pull the app from the app store just 2-3 months after its release.
    I keep trying to find a parallel for the business model in this new book app world. What is Adobe's role if we were talking traditional book publishing?
    - The book store? No, that's the role of whichever app store the app is sold through (Apple's App Store, Android Market, etc.).
    - The distributor? Possibly, since you could consider Adobe hosting the files as a type of distribution service (although, I'd prefer to host it all myself). If Adobe is the distributor, $0.30/download seems reasonable.
    - The press? I suppose this could be argued since Adobe takes an input of files and outputs an app like a press takes an input of files and outputs a printed product. That's sorta like a press. But if that's the case, a per app fee (or even a per download fee) makes more sense than a monthly carrying cost. We don't pay our presses monthly after they've printed our books for the right to sell them. 
    Obviously, there's a flaw in thinking about this new world in old ways, but I'd still like to figure out exactly what Adobe's role is and why we (or our clients) would pay Adobe monthly. If, for example, Adobe's pricing scheme was something more like $400 per app created (with all features like renditions, updates, social sharing, etc.) + $0.30 per download to host the file with an option to bypass Adobe's (shaky) hosting service, we'd jump into DPS with no reservations and be publishing dozens of apps per year. Instead, we're dabbling with publishing one app and working as quickly as possible to find other solutions, which would eventually lead to converting our Adobe Create Suite based production team to an HTML/CSS/Javascript team.
    Thanks,
    Chris
