ActionScript 2.0 :: Audio Timeline Scrubber?
Feb 23, 2009
I am trying to make a scrubber that will allow me to scrub through the root time line which has streaming audio on it. I have created audio players before where the file was being streamed in from an external file, but have not dealt with it ever being on the timeline.
[Code]...
It works pretty well, however, there is a problem. When I scrub the bar, the audio stops playing. I am assuming it is related to the enterframe function, but I am not sure on how to correct the code.

I've been looking for a tutorial to create a timeline scrubber (not animating specific movie clips, but actually a scrubber that can move along different keyframes of a timeline that has a series of images on it).I found a bunch of these (scrubber controlling specific movie clips): http:[url]....but nothing that allows you to just scrub back and forth on the whole timeline in the exported swf.

Are there any examples or tutorials on AS3 scrubbers? I cant find any that don't deal with flv control... I need swf timeline control and dont have the knowhow to convert an as2 version.

I am building a timeline with a scrubber. The handle on the scrubber is a movie clip, and it was all working fine. But I didn't like that when you clicked on it, the hand icon would be glued to the left hand side of the handle. So I changed to registration of the handle file so that it would be in the middle. Now my 'onReleaseOutside' command quit working. If I set the registration back, the release command works again.
Basically, if I drag the handle all the way to a side and have the mouse continue past the flash file and release it, it wont register it has been released until I move the mouse back over the flash, which also moves the scrubber handle to _x location of the mouse for where ever it entered the swf. Is there something obvious I am missing? Or do I have to deal with an un-centered handle?

I have a series of movies I'm creating that have streaming audio with animation synced to the audio. I was wondering if there is a component out there, or an FLA, that is a scrubber control bar like the one you see in Articulate Flash presentations, or video.I need it to control the main timeline.I have searched google for a while now and I can't seem to find one.

how to build a timeline scrubber that can scrub more than one scene.
1. Scene 1 had 20 frames
2. Scene 2 had 20 frames
3. On scene 1 I put the slider that scrub the timeline. The totalFrames; sum all the frame from all the scene.
4. When i scrub the slider to frame 21 error occurred saying that the slider couldn't be found. So i paste the slider in scene 2.
So how to continue scrub on scene 2? How to make a slider that can scrub all scene and move along showing the current frames?

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 ..

The images for animation load okay. The sound loads okay. But the animation images need to be inserted in coordination with the sounds, which is difficult using only the ears There is a visual graph of audio levels in the library window, which I have seen appear in the timeline also but only momentarily. I do not know how to keep the audio graph on the timeline so as to know where to put the images. I can keep the graph open on the little library window when it is open but not on the timeline. how to keep the graph open on the audio track while I work on the image tracks.

I am making a player that adds an advertisement before a video but don't want the user to be able to skip though the ad. I am using the progress component and an FLV Playback component for my player. I had tried to just hide the progress bar but it looks unbalanced. If anyone has an idea on how to make it so a user can not fast forward though the ad by dragging the scrubber that would be great.

I'm looking for an animation timeline or video/audio timeline ui or maybe like a gantt chart thing that can be adjustable. It's basically draggable icons in tracks and bars that you can adjust the size of.

I'm having an issue that I never ran across using AS2, and I'm completely baffled. I'm making a program that is going to be, more or less, an interactive training program. Each frame is a separate "page" of training, and has its own unique audio clip that plays.
The frames are laid out like this: On the main timeline, there is a movie clip object. Inside that object is the interface the user interacts with, along with a movie clip that contains the audio, set to stream (I have it set to stream because they sometimes have to move around in the training within the timeframe of that audio clip. If I have it set to event, I can't have them skip a section of the audio clip, etc)
Things have been going well, but I just added a new layer to my main timeline, containing a navigation bar (a few movie clips), and all hell has broken loose. Every single audio clip starts playing at once, right from the beginning, even though the frames that contain those audio clips haven't even come up yet.Are audio clips used completely differently in AS3 than AS2? I've figured out the SoundMixer class, and I have SoundMixer.stopAll(); on the first frame of each movie clip that contains the audio clips (the audio clips start on frame 2) as a safeguard, but man.

I just started using CS4. I have one problem with audio played from timeline in multiple scenes. The first 2 sceense work fine but the 3rd one has problem. The audio would pick up the last brief second of the audio before the current one and then plays the current audio. The pick up includes the last second of the last audio of the previous scene or the clip from the current scene.
If I copy all the frames in the problem scene into a new file, audio plays perfectly.
Have anyone seen something like this and what is the cure?

I had a timeline with 3 sound effects, back to back, with a this.stop(); at the end of each one (...so there's three separate sections of a timeline, with a label at the start of each).... and when I'd play it (from the start, for example), it would play the first sound effect (as expected), and stop before the second section (where the next sound effect was)... yet the second sound effect would trigger!
Even when watching it in 'Test Movie' mode, I'd see that it stopped before the next section, yet the second sound triggered (many frames before the stop command I tried putting more space between the sections... and putting the samples on different layers... yet it ALWAYS triggered the second sample, even though the frame it started on was never close to being reached!

I'm trying to stream *.wav files on a webpage and looking for a flash program which will show the full audio waveforms. Something like this:
How to do this? Again, streamings not the heard part, I just need to allow users to see the waveform timeline.

I've been given FLAs that contain audio embedded within the timeline. It's been a long while since I've had to deal with audio in this manner and I'm running into a problem.
The basic setup is this:
- There are 3 movie clips within the FLA
- Each movie clip contains embedded audio within the timeline
- The audio plays as soon as each movie clip begins
Here's my issue:
On the main timeline, there is a 'back' button which allows the user to move to the previous movie clip.
When the user clicks this button, it does move back to the previous movie clip; however, the sound does not stop which results in 2 audio files playing at the same time.
If I were calling the sound utilizing SoundMixer/SoundChannel, I know how to ensure the audio stops, but since the audio is embedded within the timeline, I'm not quite sure the best way to make sure the audio stops when the preceding movie clip is called.

I am having trouble with an embedded audio clip. (embedded in the timeline) First, the reason for embedding.... I need the audio (voice over) to correspond to the on Stage animations, and have words and animations appear when certain keywords are spoken. Second, here is what I have tried...
1) I have tried to embed the audio clip directly on the timeline. The audio file I am using is an MP3 created out of Garage Band. (Mac audio program) When I embed the clip, and publish a preview, it nearly crashes Flash Player. The audio continues to play, but all on screen animations are severely slowed and choppy. And I must force quit Flash Player to close it. Plus it is nearly maxing out my CPU during playback.
2) I removed the audio clip from the timeline, and decided to try AS3 to import and control playback of the audio clip. This seemed to work fine, no slowdown, less CPU usage, and on screen animations seemed to play normally. However, it is nearly impossible to sync the audio and on Stage animations with an externally loaded audio clip. (timing is always different depending on computer and internet speed.)

I'm working on an audio player with a scrubbable playhead, per Kenny Bellew's outstanding tutorials [URL]In order to learn the mechanics and test drive it, I was able to create a fully functional model in its own movie. Now I'm trying to apply it to an MC nested in a larger project and I'm having trouble.The main website (w/o the audio part installed) is [URL]A smaller version that only has the part I'm working on (for this question) is [URL]The songloading and play/pause/stop are working fine. (I'll be adding a song loading preloader later--the songs are dynamically loaded), but I can NOT get the playhead working completely. It will track the progress of the song, but if dragged, the song stops, the playhead snaps back into its original place, and the song stops for good (until re-loaded).
I'm just calling something incorrectly--the whole Audio section is in the _root.Audio MC, and the songs are loaded in to audioSong.
The code for the drag head:
------
onClipEvent (load) {
startPosition= _root.Audio.hslider._x; // hslider is the knob.
left = _root.Audio.hslider._x;
top = _root.Audio.hslider._y;

I have a narrated fla which needs to have an audio mute button so you can mute the audio, problem is I can only find how to do with streaming audio. I need this done off a button where the audio is on a layer inside the timeline.

I don't use Flash that much so the question may sound simple, but how do I pause audio in a timeline? I have added the audio, play and stop button. When I test it works fine, but I can't figure out how to add the pause button, or the play/pause button.

I'm having problems with many files losing their assets from the timeline after a save and reopening the file in Mac OS X Snow Leopard. This is happens quite often now and there seems to be no pattern to it. For example, I will open an existing Flash animation complete with sound and artwork, make changes to the animation timing, test the SWF and everything looks good, then save. After reopening the exact same file, there will be audio that was on the timeline will be an empty frame. In addition, there is art work that was swapped out or updated to a character and the symbols becomes empty after reopening.

I have a swf that has embedded audio on the swf's timeline which is set to Stream. This swf is then loaded into my main flash timeline via the loader class. I have a button coded as a toggle switch that pauses the loaded swf via the stop() and play() command. This works fine. The issue is that when the swf is paused (stop()), the audio is longer heard, but it continues to play. When I press my toggle switch again, the swf begins to play exactly where it was paused and the audio is now heard, but the issue is that the streaming audio is now out of sync since the swf timeline paused, but the audio continued to play. Is it possible to stop or pause the embedded audio on the timeline? I've tried looking at the SoundMixer static class, but this doesn't seem to help. I can use SoundMixer.stopAll(), but there's no way to start the audio again.

The site in question is [URL] - I've got streaming audio playing as background music, however after someone clicks the stop all sounds button it stops, however when the background music reaches the end of it's timeline, it starts back up again. How do I get it to stop forever? Also, how do i get this button to have two functions, off and on.. without embedding the audio, I want it to start and stop the streaming audio.

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.
