How to normalize audio (streaming .mov output)

We are trying to figure out how to normalize audio. We're using v. 3.0.5. Tried Peak Limiter, and tried the highest setting, and the highest amplitude samples of the waveform did indeed reach 100%, however the noise floor was raised significantly more in proportion. We are looking for a function that will take the guesswork out of the audio settings -- i.e., the typical normalization function you find in most audio editors. Set the percentage of digital full scale that you wish the loudest peak to reach (e.g., 97%), then the entire waveform is increased an equal amount. Even better yet if there is RMS normalization, but I doubt that is in the app. Thank you.
Chris

In FCP you can select your audio, choose Modify -> Apply Normalization Gain and set the threshold. In some cases it will raise the noise floor, but so will any automatic plugin.

  • No audio streaming movies with iTunes 10.2.1 and iOS 4.3

    I upgrade to iTunes 10.2.1 and to iOS 4.3 and now I can´t listen audio on my movies with 6 channels audio. With two channels (stereo) there is no problem. With multichannel I just can see the video, but can´t listen. The problem is with my iPad and my Apple TV. On my iMac it works fine, I can see and listen.
    Anybody Help ??

    I have the similar problem with video. I can not stream movies to apple tv after ios 4.3 update that i used to stream before. The problem seems to be for some (but a lot) specific movies though. After going through all my videos i found a couple of videos that was able yo be streamed. Even with movies that can't be streamed the video loads (and even plays on fast forward but very slow without audio) but just pauses. It just loads opens and everything but just doesn't play.I don't have any problem with streaming audio from ipod or etc. I can still stream video from youtube as well but just can't do it from my itunes.
    Just to be specific, i have the issue with my ipad as well. The movies that i can stream to atv can be streamed to ipad as well (from my pc windows) but for other movies neither my atv nor ipad can play. A clear **** up by the developers. Just can't understand how they can release without even checking possible flaws.

  • How to sync Audio and Movie?

    I record "my hands" playing piano by an external web cam and record audio by line.
    The Movie- the movements of my hands- is slower than the audio. How do I sync this in Quicktime 10?

    There should be a setting on the camera for the audio bitrate.
    Quicktime 10 does not have a preference panel. Better to use Quicktime 7.
    Also check you settings in Audio MIDI setup:
    1. Open Audio MIDI Setup (/Applications/Utilities/), then check the Audio Output setting.
    2. Change the Audio Output setting to 44100.0 Hz.
    3. Quit Audio MIDI Setup.

  • Reading an audio stream before output

    I'm working on a project that requires me to read frequency data from audio that is being played on a computer. However, I would prefer to use my default music app, and not something hard-coded into this program.
    I would prefer to do this without having to split the audio output from the sound card and loop it back to the mic port.
    Is it possible to do this using JMF? If so, how?

  • Does anyone know how to transform audio to movement?

    I know there was other discussions about similar subject, but what I'm looking for is to mimic what's on videocopilot website.
    The tutorial is called audio to animation and the link is
    http://www.videocopilot.net/tutorials.html?id=64
    Is this possible in Motion 3? I've been trying to mimic this by my own, but I can barely able to control replicated object.
    Any suggestions?

    Did you use the Audio parameter behavior? It's pretty straightforward and quite powerful.

  • How sharing an audio stream in two or more Ip telephones?

    Hi everybody.
    I wonder if you can make a call in which two or more people can listen to the conversation without using the functionality of the conference or the contact center, in other words, two or more IP phones have the functionality to take the call and listen to the conversation.
    analog lines similar to accounts in which a line with several phones and all phones that are connected to it can hear the conversation.
    I hope you understand me
    regards

    Hi Mauro,
    You can use "Shared Lines" with Barge
    Look for "Single Button Barge"  to simplify the user experience.

  • Real time audio streaming

    Hi, I need to develop a j2me softphone, is there someone who can tell me how to do audio streaming ? I already read jsr135 but nothing important.
    I would appreciate any help.

    Hi Daniel,
    I'm encouraged to receive a response!
    I can't see how the advent of a new codec will affect the issues that I mention above. You still need an unreliable protocol to transport the Speex data! Datagram support is optional in both MIDP2.0 and it's my understanding that it is rarely implemented. The objection about Bluetooth remains - L2CAP support is optional, and setting the flush timeout on an L2CAP connection is impossible.
    Then there is the question of playing and recording at the same time. The anecdotal evidence seems to be that even though you can use threading to start two players at the same time, as soon as you try record and play at the same time, an exception is thrown (sometimes the emulators work but after deploying on the device the exception is thrown).
    Finally, you mention that there are a number of Java ME VOIP applications out there. Do you have links? Personally I can't find any. What I can find is a number of products that operate on different platforms:
    eg Fring that has Symbian, iPhone OS, Windows Mobile and Java ME versions.
    What is telling is that the Java ME version does not support voice, while the other versions do. The same applies to Nimbuzz and Talkonaut. Extensive googling has not revealed any exceptions to this rule.
    If you can prove me wrong it'll make my day :).
    Cheers,
    Fritz

  • Premiere CS6 won't import mov files, the message: "file has no video or audio streams" shows up instead. How can I import the files?

    Premiere CS6 won't import mov files, the message: "file has no video or audio streams" shows up instead. How can I import the files?

    MOV is a wrapper that can contain many different codecs. The message you get is indicative of a distribution codec inside the MOV wrapper. You may need to convert the material to an editable codec before importing.

  • How do I create a streaming movie in QT Pro??

    I have a Darwin streaming server and I'm trying to figure out how to stream movies on it.
    I've got QT Pro and I understand that I need to use this, somehow, to encode videos correctly for streaming.
    How do I do this?
    Do I need a ".sdp" file, and if so, how do I get one?
    Darwin Streaming Server appears to require one as a playlist option, 'mount-point'.

    When you encode your files you must make sure that they are hinted. Here are some general directions for creating sutable media. This is taken from a ducument that I am writing for a university at the current time so the applicable copyrights apply.
    There are many codecs which can be wrapped in a Quicktime Move but only several codecs which can be wrapped in a Quicktime Movie, can be streamed. Several of the compatible streaming codecs include MP4, H.264, AAC and Sorenson. Additionally the Quicktime files MUST be hinted. The easiest way to create compatible files is with either Quicktime Pro or with iMovie. Neither of which are free. Free tools exist but they are very difficult to use. One way to create a compatible file is the following. Please note that the following directions will cause you to create a standards compliant file. In Quicktime Pro choosing export and in iMovie by choosing Quicktime Advanced export. Choose Movie to MPEG4. Click Options. File format should be MP4. Change the video format to H.264 and set the data rate to 1000 kbs. You can use any value that you wish but 1000 kbs looks very nice also note that this file probably will not be playable for anyone outside of the LAN unless they have an extremely fast internet connection. Your total kbs of both the video and audio must be less than that of the end users internet connection. For example for anyone unfortunate enough to still be on 56k would need the file to be under 56 kbs, 44 kbs would be a good bitrate to use for them. You can use any image size that you choose but note that the movie will usually look better at a smaller size. You can leave the frame rate at 30 but if you do not have any fast action sequences you can easily reduce it to 15 without much loss. Click Video options. If you don't mind spending more time encoding the file then change the encoding mode to Best quality but if you don't have the time to spend encoding then choose Faster encode. Change video to Audio and make sure that the audio format is AAC. You can reduce the data rate if you wish but if you have any music then it will sound terrible if you reduce the quality much below 128 kbs. If you only have someone speaking in the video you will most likely want to change the movie down to one channel (mono). You can also change the output sample rate but 44.1 kHz works well. You can also increase the encoding quality if you want better sound. Change audio to streaming. Make sure that the box is checked for enable streaming (if that is not enabled then no matter how you encode your file it will NOT work on the streaming server). Also make sure that you click the chick for optimize for server. Click OK and save. Some time later your movie will be encoded. To link to the file first place the file on the streaming server. After it is there play the file using Quicktime. The formula for the address to open it is rtsp://servername/path-to-file/filename.mp4 (or rtsp://servername/path-to-file/filename.mov). If that works without a problem in Quicktime Pro click save. Choose the option to save a reference file and press save. Place the reference file on the web server and link to that reference file just like you would any other file. (If you used iMovie there is a free tool made by apple for mac os x to create hinted files. The tool can be found here: http://developer.apple.com/quicktime/quicktimeintro/tools/index.html .)

  • How do I embed streaming audio into a PDF?

    I've seen threads and question on embedding a YouTube video which I can do, but haven't seen anything regarding streaming audio embedding.  There are music sites out there that let you embed their song players (Soundcloud for example), how would I go about doing that?
    I also wouldn't mind embedding a YT player w/only the player controls as well (see below), but I can't figure out how to do that either.  Your help is greatly appreciated, being trying to figure out how to do this for hours now.
    FYI, I know how to embed audio, but I would rather stream the audio to keep the file size small.

    Ok I'll be honest, I'm really not following you here.  Exactly what is an "annotation"?
    It will be a series of MP3's, when I tried copying and pasting the embed code I get an error that reads "Unsupported 3D file format" .  Below is the embed code I pasted into Multimedia-->Flash Tool

  • How can I stream movies from amazon

    I am trying to stream movies from Amazon Prime with HDMI cable and continue to get message that says: AirPlay mirroring and HDMI output are not currently available. To AirPlay video to an Apple TV, first disable mirroring: Swipe up from the bottom of the screen to access control center to find AirPlay options. 

    Sorry, got distracted and posted prematurely. 
    This appears to be an ongoing issue with amazon and netflix.
    Can not find an answer.
    Maybe someone else knows how to solve.

  • No audio in any streaming movie?!?!!

    So I'm not sure if it happened with the Quicktime 7.0.4 update, or if it happened with the OS X 10.4.4 (combo) update, but now when I go to watch ANY streaming movie, I have video, it's really smooth, I kinda like it, but now there's no audio. Up until about a half hour ago I was also sporatically losing my interface sounds (send to trash, empty trash, etc).
    I tried loading a TV show preview in iTunes through the iTMS and it worked just fine, but if it's in Quicktime Player.app, it's a no go.
    I have repaired permissions, reinstalled Quicktime 7.0.4, reinstalled the 10.4.4 update, reset my PRAM, ran /sbin/fsck -fy in single-user mode, cleared ALL caches (/Library/Caches/, ~/Library/Caches/, /System/Library/Caches/, & /System/Library/Extensions.kextcache) and NOTHING works.
    I guess my next step will be to try and run the uninstaller for Quicktime 7.04, and get back up to Quicktime 7.0.3.
    Anyone else having this problem? I know my fiancée's iBook was just last night as well... both tried loading the Macworld SF 2006 Keynote and got video, no sound.

    Ah ha! Apparently the audio output got changed to 96KHz in the Audio MIDI Setup.app.
    I found my answer through this post:
    http://discussions.apple.com/thread.jspa?threadID=309078
    which had a link to the single post that contains the real fix:
    http://discussions.apple.com/thread.jspa?threadID=310556
    I'm running on a new... maybe not so new now that the MacBook exists.. but anyway, I've got one of the new 17", SuperDrive DL, higher-res PowerBooks, maybe the digital audio made this odd change possible, the installer must've just changed it.. dunno.. anyway, problem solved! I've got audio in streaming movies .

  • Can I deal with the audio stream while recording?How?
