Sound recorder with ActionScript

Is it possible to build a sound recorder
with ActionScript? I know that you can
do it with a Flash Media Server. But that
requires a steam and a server.
I just want a simple recorder/player so
that a user could test and adjust the
settings of his/her microphone by visiting
a web page. A user should be able to do
it without any server resounces, since the
sound card/microphone/audio are already on
his/her desktop.
I'd appreciate any suggestions, with or
without ActionScript.

AFIAK not possible without a media server. But you can use
the open source media server "red5". Its free and can do everything
(at least thats what the developers say) the Flash Media Server can
do.

Can I make professional sounding recording with Logic in an untreated room?

I have a small bedroom-recording studio. Since starting with Logic over a year ago I have been amazed at how much you can really do with this program. I would really like to start producing my songs at level that competes with the sound quality of what most people purchase on Itunes and professional albums. However, I don't have the space or money to record and mix in an acoustically treated room. It's my little 10x12 bedroom in California after all, and I also have to keep everything else I own in the same space.
Some people argue that an acoustically treated room is the most important thing in getting a truly great sounding record, BUT my question/argument is that IT IS possible to get a pro recording without elaborate foam set-ups and bass traps, etc. Here are my thoughts and please feel free to agree or disagree and prove me wrong—also note, I am NOT talking about mastering, just getting quality recordings and mixes before the mastering stage (that I would pay a pro to take care of anyway).
I have good monitors for my setup (Event ASP6s and have had a few professional recording artists I know comment on how good they sound). I listen to music all the time on these speakers and know them very well. When I record my own music I frequently A/B my recordings (as I am recording AND mixing) with music from CDs to match the sound quality. I focus on both total recordings and specific instruments when doing this A/B strategy. I also mix at low volume levels.
My thinking is this: If I'm able match (or at least come close to matching) the sound of my instruments and mixes to a commercial recording using my speakers and Logic, then the room should not matter. The speakers are reflecting the sound of a pro recording, regardless of how the room is treated, and I am in turn emulating this sound with my own music. Thus, my music should translate well on other systems, as the pro recordings obviously would do so.
I realize that quality mics, preamps, mixing skills etc. are important for creating a professional, accurate sounding project as well, but the fact that I am unable to record in a properly treated room has always bothered me and I’m not going to be able to change this situation any time soon.
I’m curious about everyone’s opinion on this. This is a great forum and there are a lot of knowledgeable people here. This is the age of the “Home Studio” and most people with home studios don’t have quality rooms, so this is an important subject. Thanks for any feedback.

Jack, I'm in a similar boat here in Seattle. I just finished recording and mixing a few songs for demo'ing purposes and was pretty happy with what I achieved, but let's just say there was a lot of learning involved with the process.
In my limited experience, when you're working in a small untreated boxy room, you're fighting a different big problem at each stage of the recording process. When you're recording, you have to deal with comb filtering and flutter echoes (if you're recording mic'd acoustic instruments), and when mixing room modes and bass-response issues. There are various ways of addressing flutter echo, which boil down to creatively using dispersion and absorption techniques and playing around with mic placement. If you close-mic everything, you can get rid of some but not all flutter problems, but then you have to wrestle with having an exaggerated low end on all of your tracks, and you lose a lot of the open, airy quality of the instruments you're recording.
My "studio" has a couple of large bookcases along one wall, so I typically recorded the guitar in M-S stereo facing the bookcases (to get some dispersion) and set up a couple of homebrewed O-C 703 panels a few feet to each side to kill off the echoes. I also set a panel up on the wall behind me to further dampen things. It seemed to work pretty well. Mixing was a whole 'nother matter. No matter how much I A/B'd I did a bunch of mixes that wound up sounding truly awful when trialled on other systems. I went through a lot of CD-R's before finally winding up with something that wasn't actively cringeworthy (at least in terms of audio quality).
Since your setup is based on an MBP and a portable FW interface, one thing you might try is recording acoustic instruments in a larger room elsewhere in your apartment, or maybe at a friend's. Or maybe rent / borrow a church for a day.
Hope this helps,

Sound recording with duration

hi all ,
i have some trouble about sound recording function.
i want to have 30S duration of sound input recording and also , if the user click the finish button
the recording will be stopped even it is still have time for recording.
i have tried to use loop with timer to take the data for 1 second period .but it will show the error
is there any other method to perform this function ?
Thank you

i have tried to use loop with timer to take the data for 1 second period .but it will show the error
is there any other method to perform this function ?
You are on the correct track here using a while loop and reading data in say 1 seconds interval. But try to skip the timer. Let the sound card do the timing details for you. Also use a larger buffer size for the sound card. You set the buffer size by the "number of samples/ch" control in the Sound Input Configure VI. Set this value to be at least 2 to 5 times larger than the "number of samples/ch" value used in the Sound Input Read VI. My guess is that you have a sound card buffer overflow problem.
Besides which, my opinion is that Express VIs Carthage must be destroyed deleted

Ridiculously Awesome Sound Recording with Video

Although I was aware that the mic's on the 928 were touted to be better at recording loud music than most other phones out there, I never had a chance to put it to the test.
Last week I was at a small bar and recorded my friends band playing. I was really close to the speakers and they were fairly loud. I made sure to turn off the sound filter in the recording setting of the video. Just for comparison, I had my brother record with me on his Razr Maxx. The next morning I played the video back from my phone and plugged in some good earphones.
OMG! No distortion at all!!! Full clean bass!!! Full mids and highs!!! Crisp and Clear! My brothers sound on his recording was a huge distorted mess! Anyone else have similar experiences? TI wanna make sure this wasnt just some freak luck with video recording...

First, what is the file format, and its specs. for the remote recorder?
Though the rates of modern cameras and digital recorders SHOULD match 100%, in the real-world, they seldom do. This make perfect syncing a labor intensive process.
One should do tests between the cameras and the recorders, to find out the % or error. Then, adjust their Audio to match first. As an example, one user in the PrPro Forum tested his Panasonic cameras, and his Zoom recorders, and found that the Zooms were off by 0.04% constantly. To correct this, he used the Time Remapping (with Maintain Pitch checked), and would apply that adjustment to all of the Zooms' files - perfect sync.
As for the Waveform not displaying for your remote recorder, did you allow those files to completely Conform (creation of the CFA and PEK files, the latter is the Waveform Display)? See this article: http://forums.adobe.com/thread/726693?tstart=30
Also, you should be able to increase the vertical zoom of your Audio Tracks, and hence any Clips on them, by hovering the Cursor over the junction between Tracks, in the Track Header, and when it turns into a = sign, with up/down arrows, click+drag. Then, you should be able to find commonality in the beginning, to sync up to. Tip: for this critical work, toggle the Snap feature OFF, with the S key.
Good luck,
Hunt

Sound Recorder with Wav sequence

Hi
I am lookin for sample code of sound recorder which displays the wav sequence while recording...
something like Windows sound recorder...
If Anyone knows... pls let me knw..
Thanks & Regards,
Chandrakanth

Look at the JavaSound Demo (http://java.sun.com/products/java-media/sound/samples/JavaSoundDemo/)
You must run it as a standalone app (java -jar JavaSoundDemo.jar) or modify your policy files, and thats tedious.
In the app, there are several tabs and select the one of capture / playback.

Sound Recording with digital out. SB 5.1 Live, + and Inspire GD

Have these on my Dell?+?also have a standard SB? PCI 28 second sound card and (nearly) Everything works. I even get DTS and Dolby lights when I play dvd's. Not from ac3 tracks of?Media Player obvioulsy (tho my buffalo link theater media streamer?and reci'ver? seem to manage but hey ho)?What i want is the ability to record off the digital out stream?without having to disable it, without?changing settings (much) and without switching to the?the second sound card ect ect. ) Could i link both cards so i record off one, whilst listening through the other one either thriough software or a cable connection?(Atomix MP3?allow you to access both cards at the same time,? no other software i have come across does.),?2)?Is there any recording software that will take a feed off the digital out?3) Is there anything else i can do in creative sound recorder / polderbits or whatever to resolve this?nb?I know that i can switch to analogue out to record, the problem then is i can't hear anything through the gd 580 unless i hook up the analogue inputs +?I only get 2 speaker output, and thats if i've rembered to change every setting correctly. Many thanks?Ian

For the first time I was able to get Dolby Digital sound through to my receiver by playing the AC3-test from creative.
And in here I also saw the passthrough settings as well.
But still not from WinDVD og Mediaplayer.
Could there be alot of codecs etc. which works against each other? -Is there a way to uninstall all codecs, mediaplayer, creative-things etc. without doing a whole windows reinstall?
Yes I have connected from the 3,5 jack to RCA on the receiver.

I am recording with Logic Pro X, using my Yamaha XS8 keyboard as a Midi controller. I also have a Thunderbolt Display. Every time I play and release a note on the keyboard, the Thunderbolt Display speaker emits a doink sound. How do I get it to stop?

I am recording with Logic Pro X, using my Yamaha XS8 keyboard as a Midi controller. I also have a Thunderbolt Display. Every time I play and release a note on the keyboard, the Thunderbolt Display speaker emits a doink sound. What is causing it and how do I get it to stop? My sound is running through the Saffire Pro 40 Interface (Focusrite) into external speakers with powered amps.
Also, When I record I am hearing little pops in the system. I have checked all of my meters and they are not clipping. What is causing it and how do I get it to stop?

Thanks for the response, but I do not have a midi interface. I am using a midi to usb connector cable, thus bypassing the need for a Midi interface.
The Mac reads the USB cable as a midi device, but not the keyboard that I am trying to use as a controller. I have tried it with my korg sp 300 and with my Nord Electro 2.
Thoughts?
Thanks,

Tristan...
This is what you have, correct?
http://www.alesis.com/usbmidicable
This from Alesis..
"The AudioLink Series USB cable receives and outputs MIDI signal thanks to its internal interface. The USB-MIDI Cable connects plug-and-play to your Mac or PC for an all-in-one USB-MIDI solution."
Notice, -internal interface-. What you have is a simple USB MIDI Interface. Most MIDI interfaces are USB.
My point is (was), MIDI OUT of the Korg goes to the connector marked MIDI IN on the Alesis, those new to MIDI often get this wrong.

Can't get sound to play back on Movie Maker when recording with internal webcam/microphone

I have a Windows 8, 64-bit Envy notebook. I tried using Google Hangouts but there wasn't any sound (the camera was fine).
Later, I decided to test the internal microphone myself by creating a Movie Maker file, and clicking on Webcam and making a recording. The camera worked but it played back in total silence.
I checked the settings for the microphone and the internal mic was properly set as the default. I turned up the volume to the maximum. Then I found directions for doing a sound check, and I was able to do the Sound Recording check and get audio when I played the file back.
But when I tried again to make a video, i got zero in the playback.
Any idea what's going wrong?
Thanks,
Pat

Hello Myerspat,

Need Help with Sound Recording

Hi,
I'm a Comp. Sys. Eng. student in my final year and I've been trying to record sound with java for a couple of months now and its driving me stupid. I've looked around on just about every java source site I could find and have found many similar examples of sound recording, none seem to work on my machine. The problem is that I keep on getting either IOExceptions, or empty .wav files (as in the code below). The code included below is a shortened and modified version of some code I got from jsresources.org, the full link is http://www.jsresources.org/examples/AudioCommon.java.html.
I have not had any experience with multimedia in java before.
Can somebody please tell me what is wrong with this code? or is my java environment to blame?
Am I declaring my AudioFormat correctly?
Am I controlling my AudioInputStream correctly?
I'm using JDK1.4 in eclipse. Any help would be greatly appreciated.

               Asking for a line is a rather tricky thing.
               We have to construct an Info object that specifies
               the desired properties for the line.
               First, we have to say which kind of line we want. The
               possibilities are: SourceDataLine (for playback), Clip
               (for repeated playback)     and TargetDataLine (for
               recording).
               Here, we want to do normal capture, so we ask for
               a TargetDataLine.
               Then, we have to pass an AudioFormat object, so that
               the Line knows which format the data passed to it
               will have.
               Furthermore, we can give Java Sound a hint about how
               big the internal buffer for the line should be. This
               isn't used here, signaling that we
               don't care about the exact size. Java Sound will use
               some default value for the buffer size.
          TargetDataLine     targetDataLine = null;
          DataLine.Info     info = new DataLine.Info(TargetDataLine.class,
                                   audioFormat, nBufferSize);

               if (strMixerName != null)
                    Mixer.Info     mixerInfo = getMixerInfo(strMixerName);
                    if (mixerInfo == null)
                         out("AudioCommon.getTargetDataLine(): mixer not found: " + strMixerName);
                         return null;
                    Mixer     mixer = AudioSystem.getMixer(mixerInfo);
                    targetDataLine = (TargetDataLine) mixer.getLine(info);
               else
                    if (DEBUG) { out("AudioCommon.getTargetDataLine(): using default mixer"); }
                    targetDataLine = (TargetDataLine) AudioSystem.getLine(info);
               *     The line is there, but it is not yet ready to
               *     receive audio data. We have to open the line.
               if (DEBUG) { out("AudioCommon.getTargetDataLine(): opening line..."); }
               targetDataLine.open(audioFormat, nBufferSize);

My recorded footage without sound will not play, but will when recorded with sound, any ideas?

Hi there community!
I have recorded alot of footage on a digital Harinezumi 3 camera and have run into a problem in post production.
Some of the footage is recorded with sound, and plays fine. However, with most of the footage, i chose to turn the recording of sound off. These files without sound will not play in any player, even when Perian is installed.
These are the specs of the video I have been able to find out.
File type: .AVI
Video Stream: JPEG
This is all I can find out, so I am thinking it is an M-JPEG file rendered as an AVI file. VLC player says it can not play the video or audio format 'undf', whatever that means. Another player says it needs a .moov encoder, but I do not see how this is possible. I have also tried attaching audio to it via Logic 9 with no success.
I am at a loss, and I really need this footage for a project. Any ideas?
Thanks for any help!!

It won't let me post the video in the forum, so here is a link to it in dropbox.
https://www.dropbox.com/s/k4nz8mg18p4thzd/Mountain%203.AVI?n=145237283
Accessed the file at dropbox. Played the DropBox "display" file in scripted player, played the same resource file using the Safari plug-in, and then downloaded the resource file using the QT 7 Pro "Open URL" option only to learn that this file was an H.264 transcode and not your original file. Used the DropBox download option to download the original Motion JPEG file in AVI file container. File plays as is in both QT X v10.2 and QT 7 v7.6.6 players under Mountain Lion v10.8.4 on my system.
Motion JPEG is one of the "lagacy" codec components turned off under Lion and which remains turned off under Mountain Lion. However, as I understand it, Motion JPEG files are supposed to be passively supported (playback supported) under these systems but requires the codec to be turned back on if you wish to export files using this codec. I turned both Motion JPEG and Motion PNG codecs back on quite a while back and have Perian installed which, as you can see, supplied the OpenDML version of the Motion JPEG codec component to actually play your file on my system. Unfortunately, since QT uses a LIFO codec component list generation strategy, I would have to remove Perian to test whether or not the system configured Motion JPEG component would then become the active decoder. (Did this a year or two ago but not willing to do so again at this time.)
Suffice it to say, the file should play in QT on your Mountain Lion system assuming the correct version of Perian is installed, it is actually active, and you have no conflicting software or hardware installed on your system. Have posted an MOV file containing your Motion JPEG video data in case you want to see if it will play correctly on your system.

Recording a browser simulation with sound (no sound recorded)

Hello folks,
I need to record a short simulation of my published [on LMS] training material using FMR mode. The purpose is to demonstrate to clients the logging in, enrollment, and course viewing.
The problem is that Captivate 5 is not recording the audio... the only audio input option available is an external mic.
Is there a way to make Captivate record 'internal' audio (as opposed to mic feed audio)?
Thank you

Ah... I suppose if I were in your shoes, I would think the same way.
I do agree with you that it should be easier... but please trust me, my Lenovo doesn't have the correct drivers and like my work laptop, not all Windows 7 systems have the "Mixer" audio device.
All this laptop has is the "External Microphone - Conexant 20561 SmartAudio HD" device.
... and yes, Show "Disabled" and "Disconnected" devices are turned on. :-(
The properties for the "External Mic" does include a tab called Listen... and with a setting called "Listen to this device". Basically, it directs/feeds the external mic input back into the speakers. With that turned on, Captivate still will not record system sounds (yes, I did restart Captivate after this setting was enabled).
The problem is that Captivate doesn't include any other Audio Input Device, except "Volume (External Microphone (Conexant 2)". In other words, it is as explicit as that, Captivate will only record what it hears through the assigned Mic.. This is quite a different setting than what Camtasia allows.
>It is my hypothesis that the capability is likely there and that TechSmith has automated the configuration for the user.
Tempting to agree with that but in speaking with Camtasia experts, they are actually using their own algorithm [built-in to the recorder] to allow system sound recording on most hardware (although it doesn't work for all computers).Therefore, there are no Techsmith added devices that I can utilize in Captivate.
After doing some research, it seems that I am in a relatively small group of computer users who doesn't have a Mixer device (or equivalent).
I appreciate your effort to help.

What is the URL for Windows Sound Recorder and is I compatible with podcast

I have recorded a podcast on Sound Recorder on Windows XP and i want to know how i can find the URL and if it is Podcast compatible. It is a wave audio file. Can you guys please, please help me!!!????
W4065 Emachines Windows XP

A recording you made in Windows Sound Recorder, until you do something else with it, is NOT on the Internet and has no URL at all.
.Wav files are not suitable for direct use as podcast episodes as they tend to be uncompressed which makes them shockingly huge to download. You'll want to convert it to mp3 format to make it sensible for sharing.
You'll then need to either upload it to a managed podcasting service, or post it on your own blog, or any of the other normal ways of doing the "podcasting" step of podcasting. There's plenty of howtos and walkthroughs on various ways of doing this.

How do I sync a audio recording with video?

Hi,
I recorded a concert using my DSLR and a separate sound recorder. What is the easiest way to sync these two up in PE10? I had hoped that at the least I could compare the wave files of both the original recording on the camera with the separate recording. But PE10 only shows the wave file of the recording from the camera. The wav file from the recorder is just shown as a green bar. Any ideas?

First, what is the file format, and its specs. for the remote recorder?
Though the rates of modern cameras and digital recorders SHOULD match 100%, in the real-world, they seldom do. This make perfect syncing a labor intensive process.
One should do tests between the cameras and the recorders, to find out the % or error. Then, adjust their Audio to match first. As an example, one user in the PrPro Forum tested his Panasonic cameras, and his Zoom recorders, and found that the Zooms were off by 0.04% constantly. To correct this, he used the Time Remapping (with Maintain Pitch checked), and would apply that adjustment to all of the Zooms' files - perfect sync.
As for the Waveform not displaying for your remote recorder, did you allow those files to completely Conform (creation of the CFA and PEK files, the latter is the Waveform Display)? See this article: http://forums.adobe.com/thread/726693?tstart=30
Also, you should be able to increase the vertical zoom of your Audio Tracks, and hence any Clips on them, by hovering the Cursor over the junction between Tracks, in the Track Header, and when it turns into a = sign, with up/down arrows, click+drag. Then, you should be able to find commonality in the beginning, to sync up to. Tip: for this critical work, toggle the Snap feature OFF, with the S key.
Good luck,
