Php :: Convert Text To A WAV File With Inaudible Waveform?
Apr 26, 2010
I am trying to create an audio watermarking system. I figure the best solution is to create an audio file (WAV) based on a unique string of text and then combine this with the original wav.The part that makes this tricky (for me anyway) is:How do I convert the text string to a wav?How do I ensure that the resulting WAV form is inaudible (or at least barely noticeable to the listener). would prefer this be done server side (via PHP, etc) but if the processing load isn't too much then would be ok with something in Flash or Javascript.

I have got three screenshots below of Flash-based audio players on various websites that draw a waveform of the clip it is going to play and moves along while it is playing and also allowing the user to click on a point on the audio file and it jumps to that point.I have very little Flash knowledge but is this easy to achieve? I would like to just show the Flash file an mp3 and it draws the waveform. I understand this could be quite intensive on CPU so would there be a way of caching the waveform data so it doesn't redraw each time the file is loaded?

I am unable to visualize the audio waveform in my flash timeline. I need to synchronize audio voiceover work and this is impossible to do without being able to see the timeline.
I am using CS4.....in previous versions I was able to see the waveform but no go for this version.....

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 come across this ActionScript sample, which demonstrates drawing of the color spectrum, one line at a time via a loop, using waveforms.however, the waveform location of each RGB channel create a color spectrum that is missing colors (pure yellow, cyan and magenta) and therefore the spectrum is incomplete.how can i remedy this problem so that the drawn color spectrum will exhibit all colors?
// Loop through all of the pixels from '0' to the specified width.
for(var i:int = 0; i < nWidth; i++)

I've got a flash 10.1 app that lets me record microphone input to a wav without a media server, which I am saving to an Amazon S3 bucket.I have another process running on a server which gets wavs from this bucket, converts to mp3 using LAME and puts them into another bucket. This all works fine, but in converting wav > mp3, about 0.1sec or so of silence is added to my sound.In the application this are being used in, perfect sync is critical, so I need to trim off that little bit. If I have to trim it off the original waveform that is okay, I don't expect anything important to happen in that first fraction of a second.
What is the best way to go about this? I am using Adobe's WavWriter to convert by ByteArray into a proper waveform. Is there a way I can easily trim off the first few samples from my ByteArray without invalidating the structure?Alternatively, is there a good server-side tool I can use to trim the wav before running it through LAME, or an argument I can give LAME? Or, could I even trim that sound off the mp3 after it has been converted?

If I have a sound waveform stored as a ByteArray in actionscript 3, how would I go about converting this into a Sound object that can be played?
Note that the array is full of sound samples - a complete generated waveform. It isn't an array containing an mp3 or other compressed data.

I'm trying to create a visual waveform for an MP3. The code I've included is called on successful load of the MP3. I intend to extract just a few important samples from the sound to create the waveform, rather than extract the entire sound into a bytearray. Even on a good machine, extracting an entire song can cause flash to freeze up for 3-5 seconds (or longer!). For my purposes, this isn't feasible.
Unfortunately, the code I've got below is failing to produce any numbers. If I extract the entire song it functions, but extraction of just the key points is giving me nothing. Does performing an extract make the remainder of the sound object invalid for future extracts? If so, is there some way around this that won't freeze flash for an extended period of time during the extract? Some important variables from the rest of the code:

I have created a booklet in InDesign cs4 that includes page turn transitions. I have saved it as a SWF file and it works perfectly on my PC with the ability to sweep through the page turns. My issue is now, what type of file can I export the SWF file to so that I can view it on an iPad and am still able to have the page curls?

I found on Adobe website this cool as3 code to grab a sound and make a realtime waveform graph (I cannot post the link..The problem, to me, is that I cannot create in the same stage 2 graph from 2 input: the mic and an mp3.In my purpose, I'd like a stage with just 2 waveform graph. the upper one with the realtime voice from the mic input.the second one (just below the previous one) with a similar waveform graph but drawn by an MP3 file (or wav).
At the beginning I tried to use 2 inputs ".microphone" but I can always see just 1 graph. It's like the resources cannot be shared (al least not so simply).

I have a flex (flash builder 4) application with a rich text editor control. I am storing this rich text output in a database via zend amf <--> php.
Now I want to display the first part of that text in a data grid. To do so it seems it might be easiest to get the plain text version.
I am hoping I can somehow convert it to plain text in PHP before I pass it back to flex?

I downloaded a youtube video which was an MP4 and used Flash CS3 Video Encoder to encode it to an FLV file. Actually improved the quiktime file. Anyway, my question is: I want to encode the FLV file to an AVI file to put on a DVD for a friend to view in their DVD player. They don't have internet capabilities [] so I can't email the link. If I can make a DVD so they can view the AVI files that would be the cats meow!! I tried using the video import wizard to import the FLV file into Flash CS3 but can't seem to figure out what to do.
