Flex :: Algorithms Use For Audio Volume Level?
Jul 22, 2009
Let's say I have a slider that can go between 0 and 1.The SoundTransform.volume also ranges between 0 (silent) and 1 (full volume),but if I use a linear function,let's say SoundTransform. volume = slider.volume, the result is rather not pleasing.I really haven't studied the human ear,but I overheard once that human perception is logarithmic, or something similar. What algorithms should I use for setting the SoundTransform.volume?

Is there a way to stream and audio line level feed rather than the audio from a computer's microphone?

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.

Is there a way to configure/control the volume level of an mp3 that automatically plays in your flash segment? In other words I'd like for the volume to play at a 30 or 50% level.

i want to control sound in my movie clip by the button which i designed in flash. for ex.: my default sound is 100% on home button & when i click on contact(last button) the volume level goes to 20% same as in between buttons.i use this script to call the sound in flash
bgSound = new Sound(this);
bgSound.attachSound("sound1");
bgSound.start(0,99);
now tell me what i put in buttons to manage sound level.

I have this code where the player can set their volume;
var my_sound:Sound = new Sound();
my_sound.loadSound("C://Documents and Settings/me.my-comp/My Documents/My Music/Unknown Artist/Unknown Album (8-09-2004 10-55-17 AM)/my_song.mp3", true);
this.createEmptyMovieClip("knob_mc", this.getNextHighestDepth(),0,0,140,64);
knob_mc.left = knob_mc._x;
knob_mc.right = knob_mc.left+100;
[Code] .....
OK, now the catch, this code works fine, however, how would I make it possible for the volume level to be retrieved in another frame and all the sounds in that frame are played at the set volume??

i've got a MC named 'enterBtn', i want the volume of 'crowd.wav' to increase when the mouse moves towards 'enterBtn' and decrease when moving away. i don't know if this helps, but the co-ordinates of enterBtn are x =530, y = 344.

I'm creating a flash presentation that contains some externally loaded video's (flv), voiceovers and a background music. I would like to be able to control all these audio streams with one control. So basically I'd like to change the volume of the entire movie. Is this possible?
I know there's something like the Sound object with a setVolume() method, but that's only to control one stream as far as I know.

Im able to stream audio with the following code:
Code:
sonido = new Sound();
sonido.loadSound("images/warp.mp3", true);
sonido.onSoundComplete = function() {
sonido.start();
sonido.setVolume(50);
}
I use this code to disable the audio file:
Code:
sonido.setVolume(0);
}
As soon as the audio file repeats, the volume goes up again.I need to know if I can keep the volume as it is once the audio loops again.

I've designed a website for a client and it's completed but she's complaining that the music on the website is too loud. I made a button so you can turn the sound on and off, but i have no clue how to make a volume button for an external audio clip and i haven't found a single tutorial on the internet that can help me with this specific issue. Can someone help me with this and give me a step by step instruction, including any code i need.

I am making a game in AS3 / Adobe AIR that requires the user to react to certain sounds. Is there a way to inform the user up front if the system volume is muted? Moreover, is there a method to change the volume? If not, does an external cross-platform application exist that lets me monitor the volume and that I can call from Adobe AIR?

it worked fine when i had the audio within the swf.slider:
slider_1.onPress = function(){
this.startDrag(true, groove_1._x -8, groove_1._y, groove_1._x -78, groove_1._y);
}
slider_1.onRelease = function(){
[code]....
i thought that in this method i had named the sound object foffMusic (streaming the file ftomm.mp3). the sound plays fine but ive gone through alot of trial and error and trawled every forum for the solution bu i can't get it to work!

I'm creating a mute button for an audio player that I pieced together, and it seems to be working alright except when I advance to a new track. If the volume is NOT muted and I click a new track it's fine, but if the volume is muted (i.e. at "0") and click a new track it remains at 0 and won't un-mute when I click the button.. though if I click the button to un-mute it and then select a new track it's fine, so I think there's something in my playSong() function that's interfering, I just can't tell what it is.
Code:
stop();
Player Variables
volume = 100;
current_song = 1;

I'm a newcomer to Actionscript programming and trying to modify a Flash site template downloaded from [URL] (which is an AS2 template). I've almost succeeded at what I need to do but have run into a couple of brick walls. One is that I've added a video player to the site and need to make the background music track smoothly fade out when the video starts and fade back in when it ends (or is stopped). I set up a listener object for the video player that works. It's the smooth fade of audio levels that doesn't.

I've got a presentation that features an audio loop for background music and streaming audio on the timeline for the voice over.When I try to lower the volume of the background music (sound object), it also effects the voice over (streaming).I'm a total novice, so try to use laymen's terms.[code]And this is on the Frame that contains the movieclip with the voice over.I'm trying to fade the background music ONLY:[code]

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.

I'm doing a project where I manually create sorting algorithms.After several tests I found out that my heapsort is way quicker than quicksort (I think it should be the other way around), my selection sort is also faster than insertion sort.I'm testing using integers from -100 to 100, randomly generated, 5000 values in an array (I modified this number several times, still the same problems).My quicksort isn't in-place.I thought that maybe flash's recursive functions are slow? my heapsort uses loops, unlike quicksort. That's just a hypothesis though. I start a timer, run the class's exec() function, stop the timer and calculate the elapsed time.[code]

I am working on a simple drawing application, and i need an algorithm to make flood fills.The user workflow will look like this (similar to Flash CS, just more simpler):the user draws straight lines on the workspace. These are treated as vectors, and can be selected and moved after they are drawn.user selects the fill tool, and clicks on the drawing area. If the area is surrounded by lines in every direction a fill is applied to the area.if the lines are moved after the fill is applied, the area of fill is changed accordingly.Anyone has a nice idea, how to implement such algorithm? The main task is basically to determine the line segments surrounding a point. (and storing this information somehow, incase the lines are moved)[code]

I am using the NetStream class with FMS to record the audio stream from the client's microphone to the FMS server.So far so good, the stream gets saved to the server as a .flv file. A php script grabs this file via ftp and copies it to the user's file store.What we need now is to either record the stream directly as .mp3 OR convert the recorded .flv to a .mp3 file - and this is where it gets interesting.
POSSIBLE SOLUTION 1 (preferred solution), Recording stream directly as .mp3:refer to Actionscipt Reference for Flash CS4:
The documentation suggests that it should be possible to directly record the audio stream as a .mp3 file. NOTE: this is with the new version, Flash CS4.I have tried this with both an Influxis account and with FMS 3.5 dev on my local machine. Both return this error:
Error #2044: Unhandled NetStatusEvent:. level=error,code=NetStream.Publish.BadName
When I publish and record just as .flv it all works fine on both servers.Is this a mistake in the documentation,

I am learning programming abstract data types. Trying to build custom hash table based dict.SO far I've created a class place holder.
public class HashMapDict implements IDict
{
private var _map:Array;[code].....
What I am thinking about is to use cryptography libs for hash generation. But I am a bit confused with how it should work. e.g. Tried to look on several libs like as3crypto (http:/url]....) and it seems to produce hash in a way I don't really think can be used for indexes in arrays.

ActionScript3 states the following:
Note: The Math functions acos, asin, atan, atan2, cos, exp, log, pow, sin, and sqrt may result in slightly different values depending on the algorithms used by the CPU or operating system. Flash runtimes call on the CPU (or operating system if the CPU doesn't support floating point calculations) when performing the calculations for the listed functions, and results have shown slight variations depending upon the CPU or operating system in use.
My web application works with very large and small numbers that I suspect may see a difference depending on which machine is running it (especially with mobile devices whose processors aren't as powerful as desktop machines'). My question is, is this behavior a function of the language?
That is, I assume some languages implement their own algorithms for the above functions, and so may be more consistent (except for differences in round-off errors introduced by the choice of processor/CPU that would exist for all languages).
Anyone know if Javascript has it's own algorithms, or does it outsource them to the CPU/processor like ActionScript?

I've created a small music player with a sliding volume control. I'm having trouble with the volume. Though it does control volume properly, if I set the initial volume to less than 100%, the volume always starts at 100% until I move my mouse over the player. At that point, the volume changes to whatever the initial volume is set to.Is this a flash bug, or am I missing something? Here is the affected code (code for other buttons/functions omitted for brevity):
var song_initvolume:Number = 100;
slider_1._x = groove_1._x + song_initvolume;
playSong(0,song_play);[code]....
I'd like to be able to set the volume at say 50%, but the above mentioned behavior happens each time.
