ActionScript 2.0 :: AttachSound - Sync Audio Clips With MC?
Jul 6, 2005
Are there issues with using attachSound to sync sound clips with Movie Clips? I currently am having this problem. I have all my sounds in a separate swf (sounds.swf), then I call the sounds like this:
Code:
gear1_btn.onRelease = function() {
logo.gear1.play();
sounds.gearssmfx.start();
}
I build the movieclips with the sound on the timeline, so that I know they sync up. Then I remove the sound from the movieclip, and actually play the sound with the AS above. The above AS should play the same in the browser, but doesn't. The problem is that the movieclip animations often run slower in the browser than they did within Flash. Is is possible that the movie is running at a slower FPS in the browser? I have noticed that it runs slightly slower in Firefox than IE. I'm currently using 32fps.
Here is my development : [URL]
Specifically, I'm having problems with the gears next to the letter "S" and "0", click on them to play.
Because the player optimizes framerate, antialiasing etc dependent on the performance capabilities of the platform upon which it is running, it was nearly impossible to ensure animation syncronization w/ audio. If the audio were on the timeline you could set sync params to stream, but if the audio is loaded programically forget it .. well until AS3 ..The following code throttles the player framerate to lock step the animation to the audio .. not perfect but the principal works ..
When I use the webcam and microsoft to record a video, my audio and video are out of sync.This does not happens when I use the built-in Microphone on the webcam.
I have an animation that I am exporting as either a .wav or .mov file then editing in different software but when I import the new file it is out of sync. That sounds confusing so I will explain. The project is a cartoon and a temp dialogue track was created before animation started. Then that temp track was used to animate over and do lip synching. Recently, actors have re-recorded the original temp dialogue track. So, I need to export the original dialogue track out of Flash, use an editor, in this case Final Cut Pro, and replace the dialogue then export that as an audio file and bring it back into Flash.
But it is always out of sync. I have even exported a .wav file from Flash then immediately re-imported it and put it on the timeline and it is already out of sync. And it is the exact same audio! I don't even know how that could be possible. Surely if you export a wav from Flash and then re-import it, it should be exactly the same.
I am streaming live content via flv but the video is lagging audio by some time. I am using netstream and video but cannot find a way to set the FPS for the video, I think i could fix it if I knew how to adjust the FPS
We are creating a 30-track mixing desk to demonstrate our percussion instruments. Take a look at www.bellpercmixer.com. As you can probably hear, the audio is not properly syncing up.
The files should be exactly the same length (8 seconds) but they are mp3s so I don't know if the compression messes the length up as I know it adds the gap between the loop? More than likely, it is my lack of action script skill that has caused this problem... e.g. does each track need to be on a separate layer with a sync-track type thing? Here is an example of the script:
I have a project that involves playing back a video clip within my swf movie. The video clip plays fine on its own, but when brought into flash the video and audio become out of sync and the movie quality suffers dramatically. I have tried embedding and streaming.
I have a voice over that I am trying to load, and sync with on screen animations. So when the narrator says something the animations back it up. However, when I embed the audio clip in the timeline, it makes my whole flash movie slow to a crawl, and everything gets out of sync anyway. When I load it externally using AS3 like this:
ActionScript Code: var my_sound:VoiceOver = new VoiceOver(); var channel:SoundChannel = my_sound.play();
Everthing works great, but I don't know how to sync it with my movieClip that contains my animations. Is there a way to have the external audio sync with a movieClip on the timeline?
We use a Flash component to allow a user on our web site to record from a Webcam on to our own Flash Media Server. The problem we are having is that the video in a 30 second FLV freezes at the 7th second but the audio continues. The video unfreezes after a couple of seconds but never catches up with the audio. At the very end there's a "Fast-forwarding" of video for the last few seconds so that at literally the last moment, everything's in sync. This happens for almost all of our recordings. Has anyone experienced this type of behavior?
I am using Flash CS3 on a PC. I am trying to export an animation to quicktime (Export > Export movie) and have some problem regarding the sound. The animation contains actionscript 2.0loads external swf contains streaming soundsplay other sounds via actionscript. 4 scenes. When publishing the animation, it works fine, but when exporting it to .mov, the audio goes faster than the video.
Export setting: Video:Compression type: H.264Frame Rate: CurrentKeyFrames: 4 Sound:Compressor: 24-bit integerRate: 48.000KhzSize: 16BitUse: Stereo To be honest, I tried many other compression types and frame rates and keyframes, but nothing seem to work.
I tried: - importing the external swfs into the original animation - creating a streaming silence from frame 1 for continuous sound - capturing the animation using CamStudio, but it's not smooth enough
I am trying to edit and mix sound effects and music for a FLASH animation in ProTools. After much trial and error I figured out how to make an accurate Quick Time of my FLASH file to spot sounds to in ProTools. The problem is when I import my audio into FLASH, it speeds up making it out of sync with the picture. I did several tests and it looks like for ever minute of ProTools the audio in FLASH speeds up 2 frames. Both programs are running at 24 FPS.
It is not a NTSC vs Flim speed issue. All other programs read my PT audio file correctly and show it to be the correct length with the SFX where I placed them. FLASH speeds it up, making my animation not time to the music and effects causing me to resync all my layers. How do I accurately export a sound file into an AIFF format and import it into FLASH without FLASH changing the speed? I have my audio set to Stream as it should be. After 3 minutes my audio is 8 frames (1/3 of a second) out of sync with the picture.
I am calling some streaming video on frames 1-11 to play for a multiple choice game. My video and audio are out of sync at times on frames 3-11? [code]...
I have a long timeline (5000+ frames) with cartoon animation and streaming dialogue sound on it. I've run into the dreaded audio sync problem. I found many discussions, peaking around 2005, but no solutions for this problem. I have a track of silence to ensure frame-dropping even between lines of dialogue. Prior to around 2000 frames the error is not noticeable.
My testing shows that playback is off by 2 frames per 1000 at 24fps. So at frame 10,000 the audio is out of sync with the graphics by 20 frames, nearly a second. This is predictable and reproducible on a variety of PCs and an iMac. I'm publishing to Flash 8 + AS2, but publishing to Flash 9 or Flash 10 don't make any difference at all.
I don't want to split this into multiple SWFs. Scenes don't help. Putting things into multiple movieclips would complicate my controls and our workflow. Just shifting the audio on the timeline is preferable to those solutions, but it makes maintenance difficult.
I'm using Flash CS4 to animate hi-def music videos. It seems that I can't keep the audio to stay in sync for anything over 2 or 3 minutes.
- I'm working a stage at 1280x720 and 30 fps
- audio is streamed on a separate layer
- mp3 publish settings are: stereo 128kbs
Inside the FLA file everything syncs perfect, but when it's published, everything drifts in the SWF and in everything else I've tried.I've tried exporting image sequences and popping the sequences into premiere pro to match up with the original wave, and i've also put the swf file in a premiere pro project as well. Whether a SWF or an image sequence, it always lapses after 2 or 3 minutes.
I created a Flash program that utilizes audio and text. The audio is located in an external folder and is loaded using .loadSound(). The text is located on the timeline and appears based on a certain time in the audio. I have a pre-loader that looks to ensure all of the external audio is loaded before the user can move onto the appropriate screen and the audio would play. This is using a combination of the .getBytesTotal and .getsBytesLoaded.
It works fine on Windows 7 but doesn't seem to be working one particular user's Windows XP on IE 7 (So it's not happen on all Windows XP). On a particular user's computer, the text is slow to load while the sounds loads pretty quickly leaving the text out of sync. After a few screens, the text will catch up with the audio.
I'm trying to record a stream from a webcam using FMS4 developer edition. The streams are recording on a linux box in .flv files. These files though have problems.
1 - The video quality is terrible. Fuzzy/blocky. Any kind of motion looks awful. Is there any way to improve this?
2 - The sound jumps/skips and goes out of time with the video.
As it is now this is useless. I am trying to make a system where a user records a short video from the camera and then I upload it to YouTube from my server. If you use Youtube's webcam page the video quality is quite acceptable and the audio is obviously in sync too, so they must know something I don't. [URL]..
I did a live stream last week using 282,482,832,1500Kbps streams. What would cause the audio to get out of sync with the live video stream? I'm trying to determine if it was bandwidth related, cpu/memory issue on the FMIS 4.5 server, or an issue with encoding PC exceeding it's limits?
Following this tutorial: http:[url].....But I keep getting this error message:1046: Type was not found or was not a compile-time constant: CuePointEvent.
how to sync to mpr3 audio files at specific points?
I've been involved in a webproject where text will be converted into speech. Then the text should be highlighted word by word as the audio is played in the browser.
The project I'm working on consists of a bunch of pages, each with narration. Each page is a separate frame on my main timeline. Due to all kinds of issues I was having, I am now loading in the audio via actionscript, rather than placing an instance of it into an object and going from there. The issue I am now having is that when I tried to simulate a download, the movie would sit on frame zero until all audio was loaded, so it took a long time to get to my preloader, and by then the movie was just about finished loading.
It was suggested that I uncheck "export at frame 1" on my audio files, but now I am getting errors that I am making a call to a possibly undefined method (random audio file name of choice). If I am loading my my audio via actionscript, do I have to load it all in on frame 1? And if so, is there any way for my movie to get to my preloader before trying to load things? I have also tried setting my publish settings to export my classes on frame 2 or 3, in the hopes of it getting as far as my preloader before stopping, but no luck so far.
Recording audios and trimming them with flash.whats the best way to go 'bout it. Is there any available component that i can use or do i have to create something from the scratch. If I have to build something from the scratch what's best way to go about it?
I have created a series of Symbol MovieClips which I load through ActionScript on the first frame of the main timeline so that they play sequentially. I dynamically create each MovieClip, add it to the Stage, and setup an enter frame listener.On the last frame I stop and remove the clip, and repeat the process with the next clip.These animations play sequentially as intended. However each clip has an audio sequence on its timeline.These play simultaneously at the start of the main timeline.I've tried each of the Sound Sync options on the first frames within the Symbol clips.With the Stop setting the audio doesn't play, but Start, Event, and Stream all cause the audio to play at the beginning of the main timeline which seems to contradict the documentation I've looked at.
Is there a straight-forward way to sync the audio to the Symbol clips, or does the audio need to placed on the main timeline?I'd rather not do this as it is much easier to sync up the audio for each symbol clip with the animation when I can work with the smaller audio snippets and not have to test the whole movie.
I've got a news-style scroller that has audio clips and text loaded in via an XML file. The text works fine and I can read the string of the mp3 file to play, but if I actually hit play, it only plays the LAST listed mp3 in the array instead of the one that should be playing.
What's happening is when you click the play button, it only plays the last song named in the XML file, and doesn't link to the correct url, but all the text is in the correct places.
hope i'm explaining this the right way. i'm using the flash flvplayback component to play a video. i've stripped the audio from the flv and am playing it, along with another audio clip, on the timeline at the same time. volume has been set for both clips, but i need to allow people to adjust the volume from the volumeBar that exists inside the video player. it's built in as2.
Let's say i got Movie A, which loads Movie B at some moment. And let's say that Movie B creates a sound, lets say:
var sndMusic = new Sound(); and then attaches it... sndMusic.attachSound("music");
[Code]....
well, when i open Movie B alone, the music plays; when I watch it while being included in Movie A, it doesn't... BUT the sounds that are simply added by dragging and dropping on a keyframe DO work on both cases. I believe it's sth related to attachSound...
2.The music player LOOPS one sound taken from an array of 3, and the sound is attached with attachSound method.
3.There are 3/4 buttons: Previous sound, Stop, Pause, Next Sound. With "previous sound" and "next sound" i actually mean next sound in the array.
So...I'm a bit "stuck" on managing the loaded and attached sounds, aka how to go to next sound, how to go to previous one etc.This is the code i've been able to write down:
Code: var soundFiles:Array = ["9052_ok.mp3", "Glimmer_ok.mp3", "Loop_9095_ok.mp3"]; function playSound() { var my_sound:Sound = new Sound(
i am having this very big problem(for my particular application). i am writing this music application in flash and i use as2 to load randomly specific sounds which are in the same folder as the movie. the problem is that i need the sound to be replayed with fidelity and it seems flash is lowering the pitch of the "music" by a halfstep(it does the same when "previewing" it from the library). musically speaking, if i have an mp3 containing A at 440 hz played with piano timbre, Flash will lower it and when it is played through the flash player is its played as a G sharp(35 hz lower). I thought that if i will replace the attachSound with loadSound and the sound will be loaded externally and not from the library the problem will be solved. it seems that this won't solve the probem. the sound just doesn't want to be played at the frequency it has in the file from which is loaded. i had read somewhere that this is a flash player's bug.
