Exception in Audio Recording in AMR encoding in J2ME?

Hi all,
I want to Record Audio in AMR encoding....
the code sniplet is as follows..
For createPlayer("capture://audio?encoding=audio/raw");
java.lang.IllegalParameterException is coming in Nokia device and
For createPlayer("capture://audio?encoding=audio/amr"); and i tried
createPlayer("capture://audio?encoding=amr")
java.lang.NullPointerException is coming in Nokia device.
so anything to change in createPlayer() while Playback the recorded audio?
For "audio/wav and audio/au "(for which it is working fine in Nokia device),
i wrote, Player p2 = Manager.createPlayer(recordedInputStream,"audio/x-wav");
so please tell me the solution?
Thanks and Regards..

Hi all,
Good Morning!
Actually i was recording in AMR encoding on Nokia 3230, but it doesnt support AMR encoding..so i had done it on Nokia 6680.
I recorded audio and played it back in AMR encoding, and in audio/raw encoding, i recorded audio but cant played it back on Nokia6680 device.
first i m displaying the audio encoding formats that the specific device supports, and then which audio encoding, the user selects,
i m recording and played it back in that audio encoding .
for eg: for audio/amr, i m recording and played it back in audio/amr encoding.
for audio/wav, i m recording and played it back in audio/wav encoding. like that for others..
like that for audio/raw encoding, i m recording the voice but while playback it, audio/raw encoding will be selected. but it is not working in that.
so which encoding to take to playback audio in audio/raw encoding?
createPlayer() while playing the recorded audio...
player = Manager.createPlayer(recordedInputStream,encoding);
for Nokia 3230, it shows that.. supports.audio.encoding=audio/wav, audio/au, audio/amr, audio/raw.
and if Nokia 3230 doesnt support amr encoding then why it shows that supports.audio.encoding=audio/amr for Nokia3230 device?
hoping to hear from u soon....
Thanks and Regards...

Giving advice on audio recording

I first started using Captivate when it was Robodemo 5 and
that was not all that long ago. I remember when I first downloaded
it. I thought it was the greatest training software ever. However I
did have problems. The most long lived problems were with audio
recordings. I know that many people have. On some of the forums I
read where one person had given up on Captivate. They did not like
the inconsistent recording of the audio. Sometimes it would be deep
and resounding the next slide would sound as if you are at the end
of a tunnel,and the very next recording would sound metallic and
soft sounding.
Just like with everything else if you are persistent enough
you will find a solution. I tried various mikes some expensive
others less expensive. They all produced the same results.
Inconsistent recordings. The recordings to me were passeable but
all not that great. Then I ordered one of those newer usb condensor
podcastiing mikes.
All I can say is wow! Those new podcasting mikes they level
out the sound.You can still notice that one recording sounds a
tiny,tiny,different than the next,but barely noticeable.
Most of us are not radio announcers or professional
broadcasters however to me the mike made an incredible difference
in Captivates audio recording quality.

Hello Rick!
The microphone is around 80 dollars, it comes with a soft
ware preamp, and I have always recorded directly into Captivate.
Even a low bit rates and encoding frequencies it still sounds good.
All my Captivate files are produced for the web. Html and .swf
files.
It is the mike Rick that made the difference. It is a Samson
microphone. It is quite large and heavy. I found out about it
through podcasters. I wondered what podcasters were using to record
audio. Audio quality would be important to them. What I wanted was
the best mike for recording onto a computer. The podcasters are
fanatics about the mikes they use.
Here is the advert from Samson.
"The C01U USB Studio Condenser Mic is the first affordable
studio condenser mic with a USB interface.
For the first time ever, musicians who record music on
computers have a simple, affordable way to capture high-quality
vocal and acoustic instrument performances.Seamless integration was
the idea, and it was obtained by creating a studio condenser
microphone that can be plugged into any computer with no in/out
boxes, no expensive computer pre-amps, just a USB cable.
The C01U condenser microphone is based on our wildly
successful C01. It features a 19mm internal shock mounted diaphragm
with a cardioid pick up pattern ensuring pristine studio quality
recordings."
Most online music stores carry these . Find one that you can
trust. Just Google Samson microphones.
Everyone can have good quality audio recorded directly into
Captivate. For those new at audio recording listen to podcasters
and other broadcasters. Animate your voice to make it more
interesting,speak at the same volume level, get a "pop" filter or
make your own with a nylon and reformed wire coat hangar. Practice
with your voice ,adjust the settings ,test various settings out and
soon you will be saying " wow"!

Logic 8 won't play back audio recorded at 48 kHz

So I was recording a small project in Logic 8 on Snow Leopard (10.6.8) the other day when I noticed that audio recorded at 48 kHz wasn't playing back at all. The wave form appeared in the audio region after recording, but the meters on OUT 1-2 weren't lighting up at all. When I switched the project mode to 44.1 kHz, the audio played back fine (except it sounded pitched down and slow). I was in a hurry so I just recorded the whole project at 44.1 kHz instead, even though it should have been 48 kHz.
Any ideas on what could be causing this?

A lot of people have reported this, and it happens to me pretty frequently. Gotta be a known bug, but of course since Apple is always mum about this stuff with absolutely no communication to its customers, we won't know until the next version of Logic is released.

Audio recording: MacBook VS MacBook Pro

So here I am.
Been reading a lot about the introduction of MacBook Pro/MacBook and I'm now really confused about which I should choose. I'm seeking for a notebook for live audio recording and the price gap between the MacBook and the MacBook Pro mystifies the hole thing.
MacBook is really tempting me since it's not that far by terms of caracteristics from the Pro. I don't really need a unique GPU since I don't really like playing games on computers. But I do use Photoshop and some graphic intensive applications and I would need room for eventual Photo/Video editing. Then, I was thinking of getting a MacBook 2 gHz (white) with 2 GB of RAM to allow some to the integrated chipset. Question 1 answered.
I've read a lot about the GLOSSY screen and I must say, I prefer the MATTE screen since it doesn't over-saturate and it isn't reflective. Though, I'm giving myself some time to hear feedback from people doing Photoshop work and having compared the results from what's on screen and what's actually printed (with a good quality printer). I'd also like to have feedback from people having worked with the MacBook outside or by a window with sunshine.
The whole issue is that the 2 gHz , 15 inch screen, 1 GB of RAM (1 dimm) MacBook Pro pro has a 227$ price difference with the MacBook 2 gHz (white) with 2 GB of RAM (CANADIAN PRICES). My budget is tight, so I want to be sure if paying that difference is worth it or I could be fully satisfied with a MacBook.
Thanks for the attention!

As long as graphic performance is not an issue (which shouldn't be for audio recording), you will be absolutely fine with the MacBook. There is no difference in spec between the 2GHz MB and the 2GHz MB Pro except for the graphics card (and hard drive speed). I use Logic Pro and Pro Tools LE extensively and have a MacBook on order. The only thing you may need is an external hard drive if you plan on running lots of tracks. You should be very happy with the MacBook unless you absolutely need the extra screen real estate or prefer the matte finish. I should be getting mine today and will report back on how I like the screen. Hope that helps!

Audio Recording Limit

Does exist any limit to audio recording in flash? I created a simple wave recording from the mic but it stop at 30 minutes or less... I don´t have any problems of computer memory I think. Does it may be from the code? or is any limitation of size (the wave can reach Gb´s...)? I have searched into the docs but have not find any related problem

SIMPLE QUESTION, BROWNIE POINTS FOR ANSWERERS: changing the file path used for an audio recording

After changing the name of an audio recording in the .band Media folder, the .band file continues to use the previous file name to try to find the audio file. I want to update the file path so that it uses the same file but with the new name. I thought I might be able to change the file path by editing projectData, but it appears to be encoded.
This is a common, crucial feature present in virtually all DAWs. Surely there must be a feasible way to do this in GarageBand?

you can't change the names of GB's assets behind its back
if you want to change the name of the region that GB displays: double click the region within GB to open the track editor, then double click the name of the region (in the track editor) to change its name

Zen Micro Audio Recording Opt

I'm shopping around for a digital music player. I noticed that the Zen Micro has an audio recording option, which will supposedly record up to 0 hours, is that correct? I was wondering if this recording would save as a file I could transfer to my computer or if I must listen to it on the device. Also, I think I read that the largest (data?) file size that can be held on the player is 2GB. Would this apply to a maximum-length recording? How big of a file would that be? Also, do audiobooks fit on the Micro? And the same questions apply to recordings taken from the radio.
Thank you!
Amber

I concur with college boy, additionally the voice recorder is surprisingly good quality, but the FM reciever gets, like all of the small portables I've owned, inconsistant to poor reception. This may be due to my location as I have seen posts on this forum claiming excellent reception. Either way, I doubt the recordings are anywhere near the quality you would get from downloading from your computer.
I have transfered several audio books from cd>computer>micro, and because the files from audio discs is usually encoded at a very low bit-rate 64kb or even less, they take up very little space on the micro.
One caution about audio books is that the tagging is usually very simple ie. "track 0, 02, etc so that with multi-disc books, which most are, you will either have to load one disc at a time and delete it when you are finished, or rename the tracks on discs subsequent to disc one or the new disc will replace the old one. When renaming tracks on second and third etc discs use two letters and three numbers.
For example: For John Grisham's--King of Torts, I named the tracks KT00, KT002 etc.
Audio discs are a nice complement to the music by the way. I get tired of tunes after a couple of hours and enjoy listening to a story for awhile. I listen to "Car Talk" and "A Prarrie Home Companion" on NPR on weekends.

Replacing an audio track without re-encoding the video

I'm new to Audition CC so apologies for the basic question. I originally asked this in the Premiere Pro forum but I think it's more an Audition question.. I have AVCHD home video (MTS video with AC3 stereo audio) and have found I can clean up the audio, for example in speeches, very well in Audition. Is there a way to just replace the MTS's orginal audio track without re-encoding the video (which it seems I have to, if I do this via Premiere Pro)? In some cases the videos are poorly lit and any re-encoding makes them look noticeably worse than the original. In any event the video does not need re-encoding, I just need to replace the audio. Maybe I need to export the cleaned-up audio from Audition and use some other program to replace the audio in the original MTS file? Is that called re-muxing? Thanks in advance for any help.

Thanks Bob and Ryclark.
Bob, our aim is to copy these videos onto USB sticks, for our family to watch on our various home TVs, from a media player such as WD Home TV, a media PC or a laptop via HDMI cable. I expect the original MTS files, with cleaned up audio, will be fine. Media Info shows these to be video: AVC format, variable bit rate, 16.0 max bit rate, 1920x1080 pixels, 25.000 fps, 8 bit, interlaced; audio: AC3 format, 256 Kbps bit rate, 2 channels, 48.0 KHz sampling rate, 16 bits bit depth. I'm keen to avoid re-encoding the video, and it seems I can. My initial test worked and tonight (I'm in Australia) I'll test further... I can edit the AC3 audio in Audition, export it as a new AC3 with the same format as original, then use some other non-Adobe program to replace the original audio track with the new one, without touching the video.
Ryclark, I believe you are right. My novice-level understanding is that the process of separating the components of a video file such as my MTS file (video, audio and possibly others) into separate files is 'de-muxing' and putting them back together is re-muxing. Audition can save or export the original or edited audio track of my MTS file to a separate file so I assume that's like a specific audio de-mux. However I don't think Adobe products can re-mux without re-encoding the video (slow, larger resulting file size, worse video quality!), so I need some other program to replace my MTS file's audio with the new/edited audio.
So far I've found the free-ware Avidemux can do it but past experience is that free-ware can be a bit flaky or over time not as bullet-proof as a good/proven commercial product, so I'll look a bit further - or does someone in this forum know of such a product? HD Video Converter seems to be an option but it looks a bit amateurish.
By the way, if anyone is after a cut/join program to remove unwanted parts of a video without re-encoding the whole thing (ie. fast, same file size and unchanged video quality) I found Avidemux (free) only works on whole frames (GOP?) and the joins can have a little 'flick', whereas for $40-$50 a program like Fame Ring Smart Cutter for MTS videos (the Sony vidcam home video files I'm interested in) is frame accurate (it only re-encodes around the cut points) and works very well (smooth cut/join points). Smart Cutter doesn't do AVI videos (for my PC screen-recording videos) but I found SolveigMM Video Splitter Home Edition works well with those (not so well with my MTS files).

How can I copy an audio recording in Skype?

I have an audio recording of one of my contacts on Skype.
Can you tell me if there is a way to copy this recording to my hard drive and if so how?
Can I do it with MP3 Skype Recorder 4.11 and if so how? Where would it be recorded to if I can do it this way?
Any help with this will be really appreciated
HB

I already have a Skype recorder for any incoming or outgoing Skype or telephone calls. I use MP3 Skype Recorder for that. What I'm trying to achieve is different.
I have an existing voicemail message in Skype itself from one of my Skype contacts. It is this voicemail message that I want to save to my hard drive somewhere so there is no chance of me losing it in Skype itself.
I right clicked on the recording and there is an option in the context menu to 'Copy Message.' I clicked on this but I don't know where to save it to on my hard drive so I can play it whenever I want from there as a file.
I would also like to know if there is any way to change this voicemail message to another file format to play on my hard drive.
Can anybody help me with this scenario please?
Thanks

How do I fix bad Quality audio recording in Captivate 4

I am having trouble recording decent quality audio in Captivate 4.
What is happening is after I do the screen and audio recording when I play it back the audio is choppy.
It also kind of sounds like the audio is quickly echoed and then clipped.
Finally this clipping and choppiness seems random when it happens.
I tested this by recording 5 minutes of the demonstration (which recorded with only 1 glitch in the beginning).
When I just recorded the second half when I played it back in Captivate it was very choppy again throughout the audio making the complete session unusable.
I am doing full motion recording of an application at 1024x768. I have tried all audio recording bitrates and have even gone up to 128kbps 16bit mp3.
I am using a high quality Audio-Technica AT2020 USB microphone.
I am running Windows Vista Service pack 2 fully updated with 4GB of memory on an Intel xeon W3503 2.4Ghz in 64 bit mode.
I have installed the latest patch update http://www.adobe.com/support/captivate/downloads.html 4.4.0.1 hoping that it waould solve the audio bugs to no avail.
Please let me know what else I may need to do to get Captivate 4 working like it should.
Are there any other settings or tests I should perform to get audio recording working.
Why would I even want to pay for Captivate 5 if Captivate 4 has worked so randomly for me.
Using 3rd party software like Audacity and even Adobe Soundbooth seems absurd when Captivate has audio recording built in.
For the time being I have gone back to Camtasia on another system because it actually seems to work but need to get Captivate working on my own system.

Try "Rapid Recorder" from store....it works well.

Why doesn't Apple supply a simple audio recording app with the iPad? (Garage Band is not simple app)

I am going to be teaching an integrated media production course in the spring semester (creating an online college newspaper) and I want the students to use mini iPads to create images, videos and sound clips. Images and video, no problem. Easy to move to our iMacs in the lab for editing and inclusion in a college newspaper web site. On the other hand, audio is a mess. Sure, I can have them shoot video, import the video into Final Cut on the iMacs and then use Final Cut like an audio editor, but that is pretty lame. They could download Garage Band but that would require all the students to have iTunes accounts, which is a real pain. And moving audio recording made with Garage Band to the iMac is a real drag and way too much work. Why the **** can't Apple include a simple audio memo program in the basic iPad app setup? This is really old school stuff that was on computers way back when. Using Garage Band for that simple function is like swatting flies with a sledge hammer.

What version of Premiere Elements and on what computer operating system?     Elements 13 on Windows 7
What is the brand/model/settings of the camera that recorded these videos?        ony PMW 320
When you import them into your Premiere Elements project, what does Premiere Elements Properties for that import give for
the audio description in the way of number of channels? If you open the Audio Meter (Window Menu/Audio Meters) and you play back
the video in the Premiere Elements Editor, how many channels does the Audio Meter display?
I just drag and drop video and when playing back only channel 1 will appear
What is your intended export for this video in terms of audio as well as video compression and formats?    MP4
I think you can only use audio if it's recorded on channel 1 or it does not recognize it.

Audio recording no longer works in Cap5 -- Ideas?

I created a presentation and recorded audio in multiple ways (Audio -- record to -- slide) (Audio icon in task bar).
Yesterday, I opened Captivate and these two options no longer worked. I don't mean that I cannot record. I mean that I cannot reach the screen in the software that allows you to record.
Recording in general works fine -- I can record to Audacity. So it's not a Windows (XP) problem or an input problem or a hardware problem.
Everything else works in Captivate.
Audio from previously recorded slides plays. I just cannot record. After using either option above, Captivate freezes and I need to click Esc to unlock.
I know, that's weird. If you don't believe me, look here. Let me know if you see me doing anything wrong while you're at it.
http://screencast.com/t/0fsLsR5Lh
So, I did what anyone faced with a weird isolated software problem would do. I reinstalled Captivate. Today, same problem.
HELP? Any ideas? I'm making final edits on my project, there is a deadline, etc. etc.

First thing to try is clearing the Cache using the button in Preferences.
If that doesn't resolve the issue, you can try closing down Captivate and deleting the Preferences folder itself.
On Xp it's located at: C:\Documents and Settings\<USER NAME>\Local Settings\Application Data\Adobe\Captivate 5
Captivate will recreate this folder next time it starts up, but any Preference settings you've made will be lost.
Also, make sure you've installed all updates and patches.

External Hard Drive and Audio Recording Application

Hi, hope everyone is doing well today. I'm new to this forum but I have been occasionally browsing it from time to time and find it very useful. So I figured I would post a couple questions that I have.
First of all I would like to tell you all excatly what I want to do with my computer. Currently I am trying to optimize my computer for the Audio Recording Application I have *Cubase SX 3* I recently just upgraded my RAM from 512 KB to 1.5 GB. My next purchased is most definitaly going to be an external hard drive, which leads me to my first question.
1. If someone could recomend me an external hard drive that is abosolutly amazing for audio recording and such around $150. I would ONLY be using the drive to save my audio files. Definitaly needs to be firewire also.
2. Next question is. I've heard of people booting from their external hard drives which has nothing but there OS and there audio recording application. That way when they boot it up they don't have processes running "Behind the scenes" and taking up some processor power. Is this true? If so, how would you going about doing this and what would I need?
3. If anybody else that is reading this is like me and does alot of audio editing on their iMac G5 computer if you could give me some tips in optimizing the performance of the computer in order to get the most out of it.
Any help would be greatly appreciated.
Thanks ahead of time everyone.

1. If someone could recomend me an external hard
drive that is abosolutly amazing for audio recording
and such around $150. I would ONLY be using the
drive to save my audio files. Definitaly needs to be
firewire also.
Hard drives are pretty much the same. 7200 rpm are obviously a bit faster than 5400rpm. Why Firewire? USB 2 is about the same speed as standard Firewire 400, but the drives are cheaper.
2. Next question is. I've heard of people booting
from their external hard drives which has nothing but
there OS and there audio recording application. That
way when they boot it up they don't have processes
running "Behind the scenes" and taking up some
processor power. Is this true? If so, how would you
going about doing this and what would I need?
OS processes are going to be running in the background regardless of which disk the OS is on, that's what an OS does! If you don't want more processes simply make sure you don't have any other apps open. I don't know Cubase, but a G5 will handle video editing along with background tasks no problem, and video editing generally involves far more data manipulation than just sound, even if you're doing multiple tracks.
You can easily install the OS on an external hard drive using your original system install disk. Simply connect the drive and choose that as the destination in the installer. To boot from that you would choose it in System preferences/Startup Disk. You could minimise that system by deleting other applications from that drive's Applications folder, turning off internet connections, disabling all widgets etc, but as long as you only have Cubase open it shouldn't make too much difference.
3. If anybody else that is reading this is like me
and does alot of audio editing on their iMac G5
computer if you could give me some tips in optimizing
the performance of the computer in order to get the
most out of it.
There's not really much else to optimise. Modern Macs are not like computers of old, and OS X is a very modern system, not requiring the type of disk optimisation etc that there used to be.
