Recording and Playing

Hello
I have a problem. I have one session of Audition recording and other session playing in the same PC. When I switch from one to another. both stop working.
I can have 2 sessions opened, one recording and one playing at the same time and I can switch from one to another, with audition version 1.5, and both continue working.
Thanks for your help.

In Audio Hardware setup, take the check out of the box that says 'Release ASIO driver in background'. It's not an issue with 1.5 because this doesn't use ASIO, but every version beyond that does.

Is it possible to record and play at same time in swift, is there a option to record without storing the file

I am making a microphone, is it possible to record and play at same time in swift, is there a option to record without storing the file

Its pretty simple with FMS. You just need to do following things:
Publish using FMLE with following settings: (just telling which are needed , rest you configure based on your needs)
Video codec: H.264
Audio Codec: <of your choice>
Server ip: rtmp://<server-uri>/<app-name>
Stream Name: mp4:<stream-name>.f4v
Application : Server-side code
application.onPublish = function(myclient,mystream){
     mystream.record();
application.onUnpublish = function(myclient,mystream){
     mystream.record(false);
Have a client , which subscribes in following live mode:-
ns.play("mp4:<stream-name>.f4v",-1,0,true);   // this is subscribing in live mode
In this way even if file is recorded, your clients are subscribing in live mode so all will be in sync.
Now if you want to disallow any clients who will try to subscribe to "recorded" file when live event is going on, you can achieve using auth adaptor. (let me know if you want to enforce such requirement)
But i think above solution solves your primary problem. Also please let me know if there are any issues in getting it work , i have given bare minimum which is required.

Recording and playing sound input from mic simultaneously in iphone/ipad

I want to simultaneously record and play the sound from a mic in iphone. As thecricket commentory application.
Please provide me a solution for this.
Is this possible in iOs.

This probably isn't going to sound very helpful, for which I apologise in advance, but I'm afraid it's the truth...
The only way you stand any way of doing any of this is by using ASIO4ALL, which can aggregate different drivers from multiple devices. But I don't rate your chances too highly, I'm afraid - USB mics have long been the problem child of computer-based audio. On top of that, you are trying to get sounds in and out of a separate device at the same time - not only that, but it's a Creative Labs gamer's device and they are second only to USB mics in terms of the 'difficult' stakes - search this forum!
A much, much better way to attempt to do this would be to use a sensible ASIO external device with sufficient inputs, and a mic that plugs into it, not a USB one. That way you could route the inputs and outputs appropriately, and use the device's monitoring so that you could monitor what you need to. I wouldn't attempt to do anything like this any other way, I'm afraid. Another approach (which can be made to work well) is to use an external mixer to do most of the work - often it's easier to set up the monitoring on these. You can get mixers with the appropriate interface built-in, and they don't cost a fortune either. Mackie and Behringer make suitable devices.

Record and play sound in SWF

Hi List,
I have developed standalone applications wherby i want the
give the
user an option of recording voice and then replaying the
recorded
sound. No need to save a file. Just record and listen.
Is it possible to record and play sound in Flash swf-files
without the Flash Communication Server?
If not is there any third party component which can help me
solve this purpose?

No, don't think this is possible without Flash Media
(formerly Communication) Server.
Search these forums though. The question is asked pretty
often, so maybe someone has offered a different answer.
Cheers!

Please help me with recording and playing audio simultaneously!!!

Right now I can either play the incoming stream OR record it. I tried making Clones for datasource like :
DataSource clone1 = Manager.createCloneableDataSource(originalSource);
Then I pass it to these 2 classes:
new playThread(clone1).run;
new recordThread(clone1).run;
playThread is a Thread class that will take the cloned datasource and then plays it while recordThread will record the incoming datasource. Here is what happens when i run them one after another:
When I run playThread before recordThread I get ACM driver error. But if I run the recordThread before playThread the playThread's playerWindow shows up and plays for a split second then stops; The recordThread does record all the incoming stream though... Here are my questions....
1. Anyone know what my problem is? is it resource alocation? Threading problem?
2. Did I use the clone datasource correctly? I tried making clone1, clone2 but those didnt work well either...Should I do anything to the clones for record and play? all I did was pass them to the 2 classes and those classes just use them straight out without proccessing or anything...
Please help me out!!!! thanks a bunch!

i dont think it is... i tried the clone thing but samething happened... it might be a Thread problem since when i put those together sometimes record runs sometimes player runs... and at the end i get "ERROR while querying ACM driver's information" error..... i am really confused...
DataSource clone1 = Manager.createCloneableDataSource(originalSource);
DataSource clone2 = Manager.createCloneableDataSource(clone1);
playerThread play= new playerThread(clone1);
recordThread record= new recordThread(clone2);
record.start();
broad.start();
anyone can help is appreciated

Recording and playing Audio at the same time

Hi,
Having problem with a MMAPI imp.
The simplest way of doing it is to start one thread playing a audio file of any kind.. As it is playing start a other thread that start a audio recording.
As soon as the audio recording is allowed to record (Security promt) the audio playback stops. And the playerListstner sends a END_OF_MEDIA event.
So my question is: Is there a way of doing playback and recording at the same time or is this a limit on the phone or the MMAPI?
This has been tested on Nokia N90 and SE W550i with same reults
Cheers
Kenth

Recording and playing sound

I am having a problem with sound in my program, it takes information from a TargetDataLine, put's it in a temporary file, then takes it back out of the temporary file and plays it using a SourceDataLine. currently, it does not play back the sound source code will follow in my next two posts.

Recording and playing back swfs

I'd like to provide a users on my application the ability to record and playback what was on the swf. I can see how to capture from the camera but can't see any way to record the swf and save it as a swf (without each user buying a screen capture package).
So I thought I might just record the basics (x,y,height,width,depth,alpha,rotation) of all the major MCs in the display list several times a second, save the details in an array and then allow the user to play the array back, creating and destroying MCs as necessary. This would be sufficient and quite efficient.
The problem is when I loop through the display list looking for the 'object.name' of each mc I just get 'instance1, instance2' etc. I can't use that to extract the appropriate MC out of the library when I playback. How do I get a consistent name that refers to the item in the display name and the library item that I can use it to put it on stage?
Also is there a way to create a list of all the MCs in the library?

Just assign the objects names when you create them then use getChildByName to retreve them.
f
import flash.display.Sprite;
import flash.display.DisplayObject;
var container:Sprite = new Sprite();
var sprite1:Sprite = new Sprite();
sprite1.name = "sprite1";
var sprite2:Sprite = new Sprite();
sprite2.name = "sprite2";
container.addChild(sprite1);
container.addChild(sprite2);
var target:DisplayObject = container.getChildByName("sprite1");
trace(container.getChildIndex(target)); // 0

Record and play

Dear all,
Anybody know whether Teststand 4.0 have a record and playback option? Please give me some links to have an idea about this.
Thanks,
Mathan
Solved!
Go to Solution.

Hai ray,
Thanks for the reply. Actually i want to do some black box testing for my device connected via USB. There is one utility named USBCV for doing tests for the device connected to system via USB. I found one sample program. I attached herewith. I need to create one application in teststand which will do all the tests (provided all the supporting dll's and associated functions) continuously for large number of iterations. So if i did the test manually and recorded for one time then we can playback for any number of times. Am i correct? How to proceed further.
Thanks,
Mathan

No live audio unless I press record and play but no way to check levels

Using Premiere Pro 6 and plugging my audio mixer into the input of my line input of the sound card, I can using Windows 7 select to hear the input all the time, say for some background music but I want to feed the mic through the mixer and lay an audio track.
So I add a new audio track, hit R and hit the recording button and then no input noise and no meters moving so hit play and hey presto, I hear audio, with a slight delay but blast - its already started recording before I setup levels etc.
Is there a work around to allow me hearing the live input when track laying this audio before hitting the play button ?
Many Thanks
Alan

On CC2014.1 you can 'meter input(s) only' in keyboard shortcuts for the track mixer.
Not sure about monitoring though, or if this existed in CS6 (before my time!)

Latency free MMAPI audio recording and play.

ByteArrayOutputStreamEx output = new ByteArrayOutputStreamEx(300000);
            Player recorder = null;
            RecordControl rc = null;
            try {
                recorder = Manager.createPlayer("capture://audio?encoding=amr");
                recorder.addPlayerListener(this);
                recorder.realize();
                recorder.prefetch();
                recorder.start();
            } catch (IOException ex) {
                ex.printStackTrace();
            } catch (MediaException ex) {
                ex.printStackTrace();
            while(stopThread != true){
                try{
                    output.reset();
                    rc = (RecordControl)recorder.getControl("RecordControl");
                    rc.setRecordStream(output);
                    rc.startRecord();
                    sleep(5000);
                    rc.commit();
                    ByteArrayInputStreamEx playerInput = new ByteArrayInputStreamEx(output.toByteArray(),output.size());
                    Player playit = Manager.createPlayer(playerInput,"audio/amr");
                    playit.start();
}Quick explaination :
The purpose of this code is to record the user and immediately play the sound , with minimal latency in between, in continous repeating loop.
ByteArrayInputStreamEx and ByteArrayOutputStreamEx are my versions of the streams that -do not - use dynamic memory, just reuse the same original buffer (300k in this case)
Another tweak I used to avoid reallocating memory for each call is I leave the recording player working without stopping/starting it and just reset the record-control.
Problem is, for some reason the recorded data doesn't really get reset ...
Any ideas ? what did I do wrong?

What do you mean that the recorded data doesn't get reset?
Does the player play anything at all?
I think you should create and call realize() on player initially outside of the loop and then start() and stop() in the course of your loop. You should also have 1 RecordControl obtained outside of the loop.
