How do I improve audio quality in iMovie?

I have heard that you can strip out the audio track in a video clip, improve it in GarageBand and then put it back into iMovie. Is this true? I'd like to improve the audio quality on a series of video talks.

Publish your movie first by going to Share and then select Media Browser.
After it is "published" open up Garageband.
Click "New Project"
Select "Movie"
Choose a name for your project.
Select your movie from the browser on the right.
Adjust your audio.
When done, you can export your movie with new audio from Garageband

How Do I Improve Audio Quality on Face Time

Can anyone advise how I can improve the audio quality on Face Time?
Video is acceptable, but audio sounds like a long distance phone call back in the bad old days, lots of background noise and voices barely audible.
I don't think its my internet connection, currently ADSL2+, Line speed 4.9Mbps, download speed 617KB/s

Welcome to Discussions, Little Eddy
Depending on whether you mean sound you hear or how you sound to others, here are some ideas for your consideration:
(1) Call from an area with less background noise.
(2) Use an iPhone. Its sound quality is superior to iPod touch.
(3) Try http://store.apple.com/us/product/MB770G/B It sounds better in my tests than internal mic.
(4) For FaceTime on your iMac, sit closer to the Mac's mic. Also test speaking louder.
(5) For FaceTime on your Mac, try a USB mic like http://store.apple.com/us/product/T6831LL/A
(6) Both you and your connection should test with other users to determine who has the problem.
(7) If sound you hear from other end, ask your contact to double check that his mic is not obstructed by a case, fingers, etc.

Improving audio quality in iMovie 4

I'm editing a video which has an audio track that consists of interviews, some recorded next to a busy street. Is there a way to clean up the track and take out the ambient noise? Note that I'm using the (antique) iMovie 4.0. Also, there is a variation in the audio levels between scenes. How do I correct for that? Thanks!

First thing you want to do is repost this to the proper group which can be found here...
http://discussions.apple.com/forum.jspa?forumID=855
You posted this into the iMovie '08 group.
But to sort of answer your question, you can not do a whole lot of audio editing within iMovie other than volume adjustments to all of it, cutting, pasting, etc. If you want to do real audio editing to try and scrub out audio noise, you will need to do that outside of iMovie in other audio programs. I can not recommend any myself from first hand experience.
To get your video audio, simply put your clips on the timeline, select them all, then do an Extract Audio command. This will mute the original audio then make COPIES of just the audio track on the timeline. Those copies can be found in the media folder of your project and you can now take those audio files and work with them in other programs.
You might start with some free ones like Audacity.

Does Encoding AAC Files with VBR on Improve Audio Quality ?

Does Encoding AAC Files with VBR on Improve Audio Quality ?
Are there Disadvantages ?
Bonus Question 1:
Usually, an 'auto' type encoding tool will screw up the natural flow of the music and miss subtle changes in the energy, volume, etc.. -stuff that is just to subtle for it to catch -Generally I wouldn't trust an 'auto' type setting to pick up this subtle stuff. Yet people say using VBR improves sound quality (and NOT file size). Why and how ?
Bonus Question 2:
What is the max bit rate VBR uses ? If I set my AAC encoder to 320 kbps and turned VBR off, wouldn't the sound quality be superior to encoding with VBR on (simply because the kbps are set at 320 the whole time...) ? Sure, the files encoded with VBR off would be larger, but wouldn't the quality be better ?
Bonus Question 3:
Lastly, I did a little test and encoded one song with VBR off and one with VBR on. The VBR song was 1.5 MBs bigger - Huh, I thought, is that increased file size the result of improved resolution throughout the whole song, or just one little section (haven't had time to listen to them)?

These are some pretty tough questions. I like VBR encoding in general, as it does allow for more complex passages to take advantage of higher bit rates while less complex passages fall back to a lower bit rate, while keeping within fairly consistent file size parameters. Whether VBR yields better results at different target/average bit rates is another matter, and really requires that you encode and properly test output files before deciding on anything but "recommended" settings.
At maximum lossy bit rates of 320 kbps, it doesn't make sense to use VBR. If I recall, the LAME MP3 encoder presets actually preclude VBR encoding for the highest quality files, and the same may be true for iTunes AAC.
I have to admit that to speak with any certainty or confidence about the issues surrounding your various questions, one would really need to encode a bunch of files with iTunes from lossless sources and test them in software such as foobar2000. I could investigate this easily on my own PC, but I don't encode music at 320 kbps AAC, since I have enough disk space to just listen to lossless files. iTunes doesn't display dynamic bit rate changes as foobar2000 does, and I haven't come across any Mac software that does as good a job of allowing for proper testing as foobar2000 for Windows does.
If you really need definitive answers to these three questions, then I think your best bet would be to do as I've hinted and use iTunes and foobar2000 if you've got access to a Windows computer to do this testing and evaluation for yourself, or sign up for a user account at Hydrogenaudio and post the same message there.

How can i improve burning quality of dvd.looks fine in preview on idvd,but final burn quality is poor/

how can i improve burning quality of dvd.looks fine in preview on idvd,but final burn quality is poor.

Had same problem with iPhoto pictures and poor burn quality. Went back to original picture file and dragged images into idvd project from there. Set encoding at professional quality and burned at slowest speed. Got very good result with high quality slideshow when played on TV.
Also tried Old Toad's Aug 30, 2011 advice to get a slideshow into iDVD with transitions, music, etc. from iPhoto.
Again the quaility of the burned CD was very good.

How can I improve picture quality...now grainy after IOS update!

How can I improve picture quality...now grainy after IOS update!

Hello, dreamer5th.
Thank you for visiting Apple Support Communities.
Here are some troubleshooting steps that I would recommend going through when experiencing this issue. They are labeled for the iPhone; however, the steps also apply to your iPad. Also, make sure to test the camera in well lighted conditions as this can affect picture quality.
Camera isn't functioning or has undesired image quality
If the screen shows a closed lens or black image, force quit the Camera app.
If you do not see the Camera app on the Home screen, try searching for it in Spotlight. If the camera does not show up in the search, check to make sure that Restrictions are not turned on by tappingSettings > General > Restrictions.
Ensure the camera lens is clean and free from any obstructions. Use a microfiber polishing cloth to clean the lens.
Cases can interfere with the camera and the flash. Try gently cleaning the lens with a clean dry cloth or removing the case if you see image or color-quality issues with photos.
Try turning iPhone off and then back on.
Tap to focus the camera on the subject. The image may pulse or briefly go in and out of focus as it adjusts.
Try to remain steady while focusing:
Still images: Remain steady while taking the picture. If you move too far in any direction, the camera automatically refocuses to the center.
Note: If you take a picture with iPhone turned sideways, it is automatically saved in landscape orientation.
Video: Adjust focus before you begin recording. You can also tap to readjust focus while recording. Exiting the Camera application while recording will stop recording and will save the video to the Camera Roll.
Note: Video-recording features are not available on original iPhone or iPhone 3G.
If your iPhone has a front and rear camera, try switching between them to verify if the issue persists on both.

How can I improve the quality of my iPod Touch's camera ?

I have an iPod Touch 4g. I noticed that the quality of the videos were great outdoors, but indoors, it's horrible. For the pictures, it's horrible outside or inside.
Do you have any tips how I can improve the quality of my camera mainly for shooting videos ?
Thanks,

All you can do is to increase the lighting.

How to improve audio quality

I got the 8GB Nano as a gift. I already had good headphones -- Shure eC4's. The audio quality from the Nano is not as good as what I get off my laptop. Fooling around with the EQ settings gives a small improvement but overall the quality off the laptop still beats the Nano. Most of my tunes were ripped at 192 using Musicmatch several years ago. Did iTunes somehow transfer these to my Nano at 128? What is the default rip rate under iTunes? Can I change it? Or is the audio quality on the Nano just mediocre to begin with?
Thanks for any advice you can give me.

You must re-import everything at the new bitrate of 192kbps. You can clear your iTunes first before doing this to ensure there are no duplicate files.
The info contained in the other post is wrong. You cannot just sync your iPod at the new bit rate you selected, this will change nothing.
When you imported your CDs at 128kbps, a lot of info was lost from the original CD. This is how compression works. Put simply, when importing the songs iTunes discards any info that you cannot hear in order to make the file size smaller. That info can consist of anything such as frequencies that the human ear cannot hear (but which may affect harmonics). The theory being that if the ear cannot hear it, it's of no use.
Once imported into iTunes at 128kbps, increasing the bitrate to 192kbps without importing the CD all over again will not replace the info that was lost originally because it was discarded and cannot be recovered, and it will not improve the sound quality of your already imported files.
If sound quality is important to you, import the CDs again at the new bitrate.

Improving audio quality of existing recording to better understand speaker

I recorded about a 1 hour recording using imovie's "capture" mode with the built-in internal microphone. On the recording there are 4 speakers talking and background noises (music). The music is making it such that it's hard to understand the 4 speakers at times. Inside of movie it seems the only thing I'm able to do is increase the volume of the overall track.
Using this or other software, is there a way for me to improve the audio quality such that the speakers are more clear?
Thanks.

I think voices tend to be in the midrange frequencies, something like 1 kHz. Maybe if you filtered out high and low and boost the midrange, you might get an improvement. Of course a lot of music is in the midrange too.
I know you can filter audio in Final Cut products. I've never done it in iMovie.

How can in improve the quality or bit rate of my iTunes library.

I need to improve the quality of my original iTunes library. How do I increase the bit rate in iTunes for the library I have downloaded or can I improve what I have or will download.

iTunes purchases are at 256k in AAC format. If you want better than that you'll need to purchase elsewhere. You can rerip your CDs at your preferred bitrate. If you have some older itunes purchases these could be in 128k protected AAC format. Every now and again the iTunes Store offers links to upgrade such tracks to the current format for a smaller fee than purchasing new copies.

Improving audio quality from a subscriber point of view

Hi,
I am building an application that requires audio chat. When the chat is happening between an Android user and a PC user, the PC user can hear clearly when the Android user speaks. However, when it is the other way around, the Android user hear distorted sound,with noises. Is there any way to improve audio received from a subscriber point of view?
Please advice, thanks!
Regards

Hi Raff,
The Android device is a Samsung Galaxy S i9000 and it is running AIR 2.6, attached below is a snippet of the code related to the audio i am using
<mx:Button x="121" y="700" height="34" width="117" label="Audio" toggle="true" id="audioButt"
click="(audioButt.selected) ? audioPub.publish(): audioPub.stop()" includeIn="LoggedIn"/>
<mx:Button x="242" y="700" height="34" width="117" label="Quality" toggle="true" id="audioButt1" includeIn="LoggedIn"
click="(audioButt.selected) ? audioPub.microphoneManager.encodeQuality = 3 : audioPub.microphoneManager.encodeQuality = 4"/>
<rtc:AudioPublisher id="audioPub" codec="{SoundCodec.SPEEX}" useEchoSuppression="true" silenceLevel="0" />
<rtc:AudioSubscriber/>
I think the problem is related to the script I am writing,I created a button called Quality to reduce the encodeQuality of my PC microphone, will it helps to improve the audio recieved from my Android device?Please advice, thanks!
Regards

How do I move audio in an Imovie Video?

I'm trying to make an Imove video. I filmed the footage in Photobooth, and then imported it into Imovie. There was a delay of the sound in Photobooth, but I thought it was nothing. So I get to Imovie, and there was a delay once again. I don't know how to get the audio to be heard when I move my mouth. It seems like there is a very simple answer to this problem, yet I can't seem to find it. Any help is appreciated!
Thanks!

(in order as in.. right after the other or right after they
land...)
this is right after the other (with a given time to drop the
next)
if they are all seperate boxes, do something like this:
on the onClipEvent(load), put an order, like drop=1,
drop=2,drop=3
onClipEvent(load)
drop=2
time=0
onClipEvent(enterFrame)
time++
if(time>drop*12) //12 frames before dropping the second
one
**your drop code
if you want them as duplicated, do this:
duplicatedmovie=[the duplicate movieclip code]
duplicatedmovie.drop=1
and in the movieclip that you are duplicating, add this:
onClipEvent(load)
time=0
onClipEvent(enterFrame)
time++
if(time>drop*12) //12 frames before dropping the second
one
**your drop code
basically the same code except that the drop was set in
different areas.
I hope it helps, but I'm not sure if it was what you were
looking for.

1.1.4 firmware update - does it improve audio quality?

I'm really confused here as I've read different opinions on various Apple ipod touch forum sites that some people swear after updating the firmware the audio quality has improved greatly (e.g. better bass/mid-range responses, louder volume). I called Apple retail store and was told no, that the only thing the firmware update fixes are bugs. Well, I still have the 1.1.3 version (mine came with the January updates) and so am debating whether to update or not. Anyone who has on this forum, have you noticed any improvement made to the audio quality?

To all: so do you guys recommend I still upgrade to the 1.1.4? FWIW, I haven't experienced any bug issue with my touch (I have yet to test the internet access of the touch, and from what I've heard some people have reported that their safari crashed with the 1.1.3 version; when they upgraded to 1.1.4 all was said to be fine).

How can I improve the quality of a photo that appears blurry when used in iMovie but not in iPhoto?

A 320 x 240, 35 KB Jpeg file looks crisp and in focus in iPhoto. But as soon as I put it into iMovie and hit full screen, it's blurry and looks terrible. A photo taken with my Nikon D7100, a 3872 x 2582, 2.5 MB Jpeg photo translates to the big screen just fine, with perfect clarity. How can I use this former picture but increase its clarity when it's magnified in iMovie?

Apologies for opening this up again:
I rasterised and embedded the photos, liked what I saw and marked the question as answered, then I zoomed out and lo! The white jaggedy edges are back! This is despite the fact I rotated them to vertical before rasterising them.
It appears that the pixels in the rasterised image are relative to the screen, not relative to the object... so when I rotate the photo it goes back to the original hi-res photo and re-rasterises it to fit the new orientation.
Also doing this has not lowered the filesize at all... It does appear that when you rasterise an image in Illustrator, the new raster is only a veneer, the original (hi-res photo) is still lurking in the background.

Any recommendations on how to get better audio quality when recording on iMovie 09?

My audio seems to lag a little & not be entirely in sync with the video.

There is no flash built into the iPad. You'll just have to use additional lighting, or find an app (if any such exists) that allows you to take time exposures (you'll need to have the iPad on a stand).
Night shooting with an iPad really isn't practical, in my opinion, particularly since the camera is of such low resolution. I'd strongly suggest you just use a digital camera or, if you have one, a cellphone with a camera and a flash.
Regards.
