[iPhone] Audio Unit examples for iPhone

Hi,
I am looking for iphone samples which are using AudioUnit.
I want to take input sound from mic and process and send to speaker. But there is no good sample code for help me. There is "aurioTouch" sample but its very advanced. Not able to understand it. Please suggest me few simple AudioUnit examples.
Thanks,

Any male-to-male miniplug cable, similar to the Monster, will work.

  • 3rd party plug-ins are not displayed in channel strip audio unit insert

    I have successfully loaded several 3rd party plug-ins (Wave Masters and IK multimedia Studio Bundle) into my MacBook Pro. The files are shown in Library>Audio>Plug-ins>Components, in User>Downloads, and they appear in my Audio Unit Manager (for each the box is checked for access from Logic Pro). Yet, when I go to a channel strip to launch some of the plug-ins, the product does not show up under audio units. How do I get these plug-in files to the insert list for my audio channels? Unfortunately, I need to launch these plug-ins in order to authorize them with the vendor. I must be missing a key step, but I have not had this issue before with other 3rd party plug-ins. Thanks for any direction.

    Also, I know in the case of my IK Multimedia Classic Studio Reverb, it will NOT be available from within my 3rd party plug-in list, on a MONO channel.
    I need to be opening the list on a stereo track (or stereo Aux), in order to be able to select those plug-ins.
    See if it's something that simple...

  • Dynex Component Audio/Video cable for iPhone doesn't just play music?

    I just purchased Dynex Component Audio/Video cable for iPhone and it plays video, but not music. It only works when I'm using Neflix or the video component of the iPod. How do I get it to just play my music?
    If I run the iPod music and open Netflix the music will play, but that is just a roundabout way of getting it to play audio and is silly. How do I get it to just play audio?

    don't think so but the component rely on normal analog signals using RCA connectors
    you can find tons of 3.5mm minijack connector and 2 rca connectors in the other cables
    they are dirt cheap and you can even make them yourself

  • Audio unit use on iPhone

    Got it , i just find the root cause : if you don't set the contents of ioData to silence, or once this does actually play you will hear some noise, so do it before render.
    AudioBuffer *buf = ioData->mBuffers;
    for (UInt32 i = ioData->mNumberBuffers; i--; ++buf)
    memset((Byte *)buf->mData, 0, buf->mDataByteSize);

  • Best method of wma audio file conversion for iTunes/iphones

    best method of wma audio file conversion for iTunes/iphones

    Fazel,
    As you know, iTunes for Mac is not capable of processing WMA files.  The two best choices are:
    Get access (even temporarily) to iTunes for Windows.  It can convert your WMA files to the format indicated in import preferences.  Use a USB flash drive to copy the files back to your Mac.
    Use a 3rd party conversion program.  The one most preferred by Mac users is EasyWMA.
    In either case, once you have the converted files, add them to your iTunes library.  Then delete the WMA originals.

  • "AuSpeechSynthesis" audio unit plug-in update for GarageBand for Snow Leopard?

    I cannot open GarageBand and use it without this plug-in updated or an alternative solution. I get this error message:
    "An error has occurred with an installed audio limit plug-in. GarageBand unexpectedly quit while trying to use the audio unit "AuSpeechSunthesis" by "Apple". This
    plug-in may require an update."
    I've looked everywhere for an update. My computer won't accept the latest version of GarageBand.

    Which version of GarageBand are you currently using?  And is your profile signature still valid? MacoS X 10.6.8 ?
    Did you install any new software or update software, before this problem first occurred? Did GarageBand ever work for you?
    The AuSpeechSynthesis plug-in is a standard plug-in, that is installed as part of the system in /System/Library/Components/AUSpeechSynthesis.component/.
    If it should have become corrupted, you will need to reinstall the system.

  • Looking for Audio Units

    Good day to all and thank you for your time.
    _Can't get enough sounds!!!!_
    I'm currently creating most of my projects with Logic's Sound Banks and Vienna Orch, however, they are starting to get boring. And knowing how expensive(expansive, too) these banks could get, does anyone know any spectacular sound banks that's worthwhile? (Looking into a lot of Eastwest ones right now, still contemplating..) How about outboard ones like a YAMAHA Motif rack? Mainly looking for drums and keys, please and thank you!!
    Additionally, I now have a couple of projects near completion and I'm looking into digital solutions to my mixdown, so has anyone found any good mixing tools/Plug-ins(Audio Units) that are better than Logic's Factory Plug-ins? (Preferably with mastering capabilities as well. And I personally do think Space Designer is top notch! Just wanted to know if there're any better out there.)
    As always, thanks in advance for all suggestions!
    One,
    Rex.

    Native Instruments' Komplete bundle will provide a huge library of sounds:
    KONTAKT 3 - sampler comes with 30GB of sounds on its own and it also provides the engine for MANY 3rd party sample libraries.
    MASSIVE, ABSYNTH, FM8, PRO-53 - More synth sounds than you'll know what to do with
    BATTERY 3 - drum sampler with a bunch of included drums, with the option of adding more
    REAKTOR 5 - A modular synth, sampler, audio processing, etc... thing. You can create your own audio thingies if you dare take the time to learn how to, or just use the included thingies or download over 1,000 user-created thingies with your Native Instruments account. I can't say enough about Reaktor.
    Additionally, I now have a couple of projects near completion and I'm looking into digital solutions to my mixdown, so has anyone found any good mixing tools/Plug-ins(Audio Units) that are better than Logic's Factory Plug-ins?
    Many, many things. I like my Universal Audio UAD plugins, Sonnox, PSP Audioware. There are so many more.

  • Analog plugins for audio units?

    I have recently starting mixing on logic due to the need for recall (client adjustments). I used to mix thru my soundtracs mrx console & got a fantastic sound that was very warm. The problem i'm getting which has been debated many times before, is the digital cleaness of software which definately lacks warmth. Can anyone tell me the best analog modelling plugins for audio units? I've heard good things about the psp vintage warmer....how good is it & what else there?
    G5 DP1.8   Mac OS X (10.4.6)   LP7.1.1 + MOTU 2408 MRK3 + REASON3 + WAVES + VARIOUS

    I´ve found that if I leave my Souncraft 1600 channels at unity gain and use the automation in Logic to mix I get the best of both: recall and warm.... The problem in digital is the summing...
    just try it, it´s really easy: make a mix in the box and bounce it. after that change the outputs of the tracks from stereo1/2 to all the outputs you have in your sound card with the channels in the analog console at unity gain. Record the mix. even an 8 channel decent sound card will sound better IMO. I disceverd this years ago when using an AW8 in 16bit and aginst all logic it sounded better... with my Multiface was even better ... I still want to try my brand new Fireface800 with this trick. just compare both mixes and tell us what you´ve found.
    ...besides that you can use your mixer´s eq and analog stuff if you like...

  • Garageband 9.0 scans for audio units on startup every time.

    It also asks for the location of my WaveShell 5.9.1 plugins.  I'm not using the Waves Audio units anymore and would like to get garageband to stop looking for the Waves audio units. How do I stop this procedure?

    Delete any Waves folder in applications.
    Delete any Waves preferences.
    Delete any Waveshells from:
    Mac HD > library > application support > digidesign > plug-ins
    Mac HD > library > audio > plug-ins > components

  • Noob question: which language for audio unit?

    Hi there, sorry if this has come up before but I'm just starting to write code on my Mac and would like eventually to write an audio unit.
    I'm at the very early stages of doing this and am unsure about which language I should be using. It seems the examples provided by Apple with the SDK are in C++, but I was just wondering if anyone had any opinions about using C or Objective-C instead?
    As a bit of background, I code in VB.Net but also have a little bit of experience in Java and Perl so I'm fairly comfortable with languages which share a similar syntax with C.
    Thanks very much,
    Steve

    Hi Steve
    I see this is your first posting - welcome
    If you're thinking of writing an audio unit then I sincerely recommend that you sign up to Apple's official Core Audio API e-mailing list.
    Go to this site: http://lists.apple.com/mailman/listinfo and choose core audio api.
    Best wishes

  • Audio drops out for a ½ second about every minute

    Hi There,
    I’m wondering if anyone else is experiencing this problem. I have a 3 G with 3.0. When listening to Bluetooth audio through the SYNC system of my Ford Focus, the audio drops out for a ½ second about every minute. It does this persistently.
    Any fixes?

    My 3GS seems to have an occasional dropout using A2DP with my Kenwood head unit, but I don't think it ever happened with my 3G (both running OS 3.0). It seems like some kind of a latency issue between the iphone and the head unit.

  • How do I start writing Audio Units in Xcode 6?

    I just don't know where to start. Just want to make a simple dummy plugin - e.g. a gain plugin - for Logic Pro X.
    Can't make head or tails of the existing documentation for writing Audio Units - seems to be aimed at a totally different version of Xcode.
    Can anyone who develops Audio Units - or who understands the Xcode ecosystem - please advise?
    Thanks,

  • In your experience what are the best audio units to use

    I hope that some of you folks are open to sharing some of your presets with others who aren't quite as good at toggling the audio unit section of garageband. I'm actually surprised that no site has sprouted up offering file downloads of presets for this section. Without the use of this section many mixes come out sound completely amateur and no better sounding than a 4-track recording vocals on a busy noisy sidewalk. For example I use the augraphiceq but it has no presets, which *****. I understand every voice has its own settings needs in editing or mastering, I just wish garageband offered a wide range of popular presets.
    So let me get to what I am in need of from you wise fellow apple seeds, what au's do you use for hip hop vocals/ rock vocals/ or any genre you record. The master presets section do you use any? If so what do you use?
    Can you detail your setting so I can create a duplicate to use myself ?
    Thank you

    Convert the footage to QuickTime DV, interlaced, lower field first with audio at 48khz, 16 bit.  In FCE, use the QuickTime DV setup.
