Capture Audio from microphone

I can't capture microphone on winxp, but ok on win 2003.
Help me.
Thanks!

[http://wiki.java.net/bin/view/Javapedia/JavaSoundDataSourceSampleProgram]
Just saw this and [http://wiki.java.net/bin/view/Javapedia/JMFQuickstartGuide]. This is great work, congratulations!
I have a small suggestion, I saw [JavaMail Forum|http://forums.sun.com/forum.jspa?forumID=43] sometime back and it has a 'sticky' which points to FAQs. It was added by 'bshannon', a poster who handles a forum single handedly, just like you :) .... So, I was wondering if you also can manage to post the link to new compilation of yours in a 'sticky' thread, then it would be very nice. I don't know how 'bshannon' managed it, but I guess you can suggest this at 'News and Updates forum' (which also has stickys of its own).
I had not visited this forum for a long time, I see your stars are at 'triple Nelson' ;-) I hope you get over it as quickly as possible :) although I am not superstitious...
Thanks!
Edit: Is Bill Shannon author (one of the authors) of JavaMail api? because here he mentions api homepage as his homepage, quite possible!

Capturing audio from microphone and save it to a file

Hi!!
I'm searching for a code using JavaSound that allows capturing audio from a microphone and save it to a file.
thanks in advance and sorry for my English

Can JMF capture audio from sound card?

I want to know if JMF can capture sound/audio from the sound card. Until now we have been capturing audio from microphone. but is there any possibility of capturing audio from sound card using JMF.
The audio captured from the sound card is to be streamed using JMF/RTP API.

Dear seniors,
i have tried to display my audio file as a graph as
x axis being the Time and the y axis beeing the frequency/pitch.
look at this post, i have mentioned all here...
http://forum.java.sun.com/thread.jspa?messageID=3073027&#3073027
is it possible to display as i desired?
wht the audio stream has? is it frequency or pitch?...
pls do give me some tips on that...
thanx in advance

I compiled and ran your code and saw
the error you described, but could not fix it ..
OTOH - here is some code I was mucking
about with recently (it was adapated from an
example I found on a forum, but I cannot recall
where), it seemed to work quite well, without
ever creating a processor.
Maybe that might help?

Capturing Audio from DAT

Hello,
I'm trying to capture audio from a DAT deck (Tascam DA-20) into FCP HD by routing it through my JVC BR-DV600U DV deck (RCA output from DAT, RCA input to DV deck, Firewire into FCP).
The DV deck's input is set to line-in, and the audio is being routed through (audio meters on DV deck mimic those on DAT deck, and I can hear the audio through the headphones jacked into my DV deck).
However, when I try to capture the audio on FCP, I am unsuccessful, prompting the following window from FCP: "Error: Final Cut Pro HD was unable to read the movie file just captured."
Now, I use the same set up I described above to capture footage from my Beta deck into FCP with no problems (route Beta signal through DV deck and firewire it into FCP). This leads me to believe that perhaps the glitch lies within my Capture Presets.
At first, I tried to capture the signal as an Audio-Only DV NTSC 48 Khz/Non-controllable device. After that failed, I tried to create my own capture preset, but am not sure it will make a difference, as the only input choices I am given are DV Audio, Built-In Audio, and None.
Any suggestions?
Thanks.

Why not capture the audio content outside of FCP, check the sample rate for 48Khz/16-bit, convert if necessary, save as an AIFF file, and then import that resulting sound file into FCP?
Any good audio app, including STP will do captures.
You are probably going to need to do some cleanup on the audio anyway before you use it, so why not just use an audio app to do it beforehand?
Besides, if you have an audio device (PCI card or Firewire device) in your Mac, you can use the S/PDIF port for your connection to the DAT and do a digital transfer when you import.
As I understand the way you are doing it now, you are taking digital content from the DAT, converting it to analog for the connection into your deck, and then re-converting it into digital when you capture it back into FCP.
One big advantage of digital audio (and video) is to avoid generation loss and added noise during transfer if you go D-to-D.
If you don't have an audio card or Firewire A/D audio I/O device with S/PDIF ports in your Mac, then see if you can find a friend who has one and can do the transfer for you. Then he can give you the file on a CD-ROM.
That's what I'd do.

Capture Audio from Mic

I am new to Java and need to know where to start with developing a Java app that can capture audio from a pc's mic, convert it to mp3, name the audio, and store it in a directory of my choosing. Additionally, I'll need an interface to that audio app that can receive function calls and args from a windows-based application.
Can you point me in the right direction- sample code if possible.
Thanks,
Jeff

I have the same problem. There doesn't seem to be any sample code for capturing an audio recording with JMF! I have browsed the web, the usenet groups and the (physical) library. It's almost like they try to keep it secret :/
There is plenty of information on how to use the JMF player, though.

Capturing audio from telephone for use in FCP

My requirement is quite specific, and so far none of previous posts seem to answer my question. So...
I'm looking to capture audio from my telephone for use in FCP. It won't be a telephone conversation, but a voice text. In other words, an SMS sent to a landline. The audio is saved as a voice message on the answer machine. My phone / answer machine is fairly basic - it has a speaker and the only ports it has is for power and the telephone line itself. I have tried a very basic method of playing the message on speaker and capturing it on a mini DV - but that results in too much audio edit to get it to sound acceptable. My Mac is a G5 and I have the full FC studio, but just not sure of best way to get audio onto the Mac without losing too much of the sound quality.
Any suggestions?
Many thanks all...

you need a telephone audio interface like the products made by the fine folks at gentner, telos or jk audio. i have a celltap from jk audio, works very very well. http://www.jkaudio.com/celltap.htm

Using Flex to capture audio from Flash

Hi!
I've been trying for a while to figure out how to capture audio from a flash-application (http://www.delorean.se/mixer)
and store it as a mp3-file.
Since I've studied Java for 2 years I thought I'd try and use it to capture the audio but I'm running into problems all the time,
and I've been advised to look up Flex by other Java users.
So, I got some questions:
Is Flex a good tool to use to capture audio from flash-applications and store the audio as a mp3-file?
Is Flex hard to learn (I've been working with Eclipse for a long time so the IDE shouldn't be a problem and learning another language/framework is always nice)
Any tips in general?
Any answers would make me very happy!
Thanks!

physical are closed : how will it managed the queues and overspill queues when target is not present? Also the data dictionary must reflect the primary but If you run capture, then you introduce rules that are not on primary: How ?

Capture audio from MIC and decode bitsream

Hi, I am new to windows phone 8.1. I want to capture audio from the MIC using MediaCapture, first I can capture to the audio using recordToSorageFileAsync but I cannot capture it to just to a memory steam, how is this done? Also after it is captured either
way the recorded data needs to be broken up into a byte array, so that I can bit decode, i.e. I need to determine what is a high and what is a low, the audio is Manchester encoded given a 1 = 25mSec on 25mSec off and a zero = 25mSec off 25mSec on, how can
I decode the audio to find out this pattern, the audio pattern will have a fixed preamble of FF followed by the data.

StartRecordToStreamAsync
method provide the possibility to save to memory stream.

Capture audio from separate device

Is it possible to capture from a camera, but record the audio at the same time from a different audio device, e.g. soundcard?
(My camera does not have a separate audio input with reasonable quality, so one could save from having 2 separate files by recording video from camera plus audio from soundcard. I'm not sure if that would really work due to latency problems, but I'd like to give it a try if possible.)
Thanks!

My practice is to capture sound separately using an hard disc recorder,from two to twenty-four tracks, and to combine this with the video in Premiere Pro. I use the sound track on the tape to achieve synchronization (which is very easy in Premiere Pro). If the room is small (<100 feet) I can use an on-camera microphone. For best results I use a wireless feed from the recorder to the camera.
It's important to use a digital recorder, preferably at 48KHz sampling speed (you can convert from 44.1 or something else, but the speed may slip). An analog source, like a cassette deck, varies too much in speed, often more than 5%, to be useful. The sync slip is usually less than 3 frames per hour of recording. Most digital recorders have a digital output which can be captured directly by the computer through firewire or USB. If your only choice is an analog sound card, don't bother - too noisy and bad timing.

How to record video or use screen capture WHILE capturing audio from Logic??

Hi,
I want to record my self playing guitar and singing using my mac book pro built in camera. I want the audio to come from Logic so I can add whatever effects I want to the vocals. When I say audio from Logic I don't mean recording in Logic and adding it in post. I want it to be on the fly.
What I used to do was use the screen capturing program Snapz Pro. I would screen capture a box around photobooth for the video, and then record while having Logic's audio in the background. It screen captures my entire computers audio. So for example if I get an aim message the bleep would show up in the recording. Or if I raise the volume or lower it the little click sound fx would be in it as well.
Capturing the audio this way let me get Logic's audio effects in my video on the fly. It worked out great....until now! :/
I just got the audio interface "Duet 2". And am using a microphone instead of my mbp's built in one. When ever I tried to record and capture my systems audio - my entire computer would crash. Snapz Pro won't work with the system audio with the interface. It works fine without it though.
I then tried to use Quicktime's new movie recording feature. I see it only gives an option for microphone and now system audio. So I got soundflower to re route the audio but that doesn't help either. This is because when you capture this way you can't hear anything while your capturing. So if I were to record a video and wanted Logics audio in it, I would have to set the output to Soundflower first. So when I record I cant hear myself which defeats the purpose.
So my final question is, how can I record video while having Logic's audio? I don't need to record with the mic, because in Logic the mic audio is going thru the system audio with everything else.
I would like to use a process more similiar to Quicktimes straight movie recording instead of doing an odd way like I used to screen capturing a box around the photobooth screen.
Thanks

Capture audio with microphone and save to disk

Hello,
I would like to know if there is any way to record audio from
user's output? Let's say I capture it using its microphone, and I
want to create an audio file with it, or a swf file or whatever
file it is. I need to save that audio for further playback. Can
someone point me in any direction!? I have been surfing on this
topic but I didn't find anything, apparently it can't be done, but
I would love otherwise.
Thank you,
JCA

Yes that's the way it could work. FMS is designed for
streaming audio, video and data around keeping things synchronised
in real time, but it can save the streams to be played back later
as well.
It would be an expensive solution if that's all you want to
do.... there is an open source 'version' in development... called
red5, but I think you need to know how to program in java, although
I'm not sure.
Or you could look at adobe connect/formerly macromedia breeze
- It prebuilt and is a pay for use service, but does much more than
what you're looking for. I'm pretty sure you can custom logo it
etc. You might want to try the free trial account and check it

Unable to capture audio from BlackMagic HD Extreme via Voice Over tool

Hi !
I'm trying to capture audio via my BlackMagic HD Extrem card using the Voice Over tool in FCP6, but I can't, no audio is incoming.
I can ingest audio with video using log and capture, then I know my card and my cables are working.
I tried to set the BM card as audio input in my Audio's System Prefereces Pane, but it isn't working either.
I've been looking on the BM website, but I found nothing.
Can you help me ?
Thx

Thanks for the reply.
Looking at system preferences I found that audio input was set microphone. Don't know how it happened. I switched it to DeckLink and now FCP displays 16 input channels in Log and Capture dialog. I didn't try to capture yet but I think it solved the problem, because before I had only two channels displyed.

Audio from Microphone Repeats - No External Speakers

This one is a little odd.
We are getting an echoing - but not from open mics /
speakers. It's like the audio is being re-routed into other audio
streams and we have no idea why. I'm working through the soundmax
drivers now.
I'm unable to get any consistent points to determine what is
happening, but it is not speakers / open mics.
Has anyone else had an echoing - more of a repeating - from
microphones?
TIA, I've found nothing from my web searches yet.

The sound / audio set up for the computers with this issue had the recording properties enabled within the audio settings - effectively re-broadcasting all of the other User's microphones within the session.

H7000 Bluetooth headset - No audio from microphone in Windows 8

Recently I bought a new HP H7000 Bluetooth headset. After I successfully paired it with my laptop (HP EliteBook 8470p, running Windows 8 and the Broadcom Bluetooth driver downloaded from Broadcom's site), I can hear audio from the headphones, but the microphone part doesn't seem to be functioning, it doesn't pick up a signal no matter how loud I speak.
When trying the same headset on the same laptop running Windows 7 SP1, the microphone is working perfectly.
In Windows 8, the Headset Microphone is Enabled in the Sound settings' Recording devices, and is set as Default Device. The Internal Microphone Array device (the laptop's built-in mic) is picking up audio no problem, so that part of Windows 8 is functioning properly. So there seems to be no issue with any of the settings, I went them through several times.
It's just the H7000 headset's mic under Windows 8, that is having the problem.
Anyone met this scenario, or even have a fix?

I managed to narrow it down to the Broadcom Bluetooth chipset driver in Windows 8.
Finally I ended up disabling it, and buying a USB Bluetooth micro-dongle with an Atheros chipset. With this, the headset works fine.
It is still ridiculous, to solve such a problem with additional investment, but this is not HP's fault it turned out.
I'll try to contact Broadcom's customer service, and keep an eye open for any Win8 driver updates on their support website.
