Ubuntu Multimedia :: Use The LADSPA SWH Gate Plugin To Remove Soft Breath Noises From An Audio Recording?
Mar 6, 2011
I'm trying to use the LADSPA SWH Gate plugin to remove soft breath noises from an audio recording, but it's not working very well for me. It'll cut out chunks of the much louder spoken audio, while leaving the much quieter breath noises intact. I mean breath noises that are so quiet, they don't even show up on the wave form. I know you can manually go in and drop silence onto each spot if you want to, but I saw the noise gate method work wonderfully in GarageBand so I'd like to use it here too, but I'm just not getting any results.I'm using both Audacity and Ardour.
I have a question about audio recording. I've always wanted to set up a sort of personal studio. Not anything too professional, but I want to be able to make quality recordings without too many problems. All I'll probably end up using is a midi keyboard electric guitar and bass. But what I was wondering was, is it a better idea to get a Mac for something like that, or will Ubuntu support that just fine? I know there's great software available, and I've got used to using Jack. But I've read problems about real-time kernel support and xruns with Jack and Ardour, and I'm just wondering if that's something that will make using Ubuntu for this complicated.
I want to do a screen capture with audio and video. I use Ubuntu 10.04 64-bit.I have now spend about half a day trying various tools, most of which seem to be half finished or abandoned. I have not found any usable docs for any of these.gtk-recordmydesktop and xvidcap will both capture video, but seem unable to capture audio from a microphone. The mic is connected and the sound preferences "input" tab shows the input level jumping up when I speak, so it must be working.
I tried the pulse audio device chooser app to make sure the mic is selected, but the choices for input are DEFAULT and "other", which shows a blank input with no choices.xvidcap multi-frame dialog has dev/dsp pre-selected as the input device, with no other options. It does not work.If I enable audio with gtk-recordmydesktop, it refuses to start and says it cannot open the sound card. There is no apparently no way to do this using the "advanced" dialog which has DEFAULT preselected as the audio input device and no other options. /dev/dsp also fails to start.I spent some time searching google and the forums here, to no avail. So should I give up trying to do this with Linux or is there some obscure method I only need to discover?I prefer xvidcap, since the ogg format output by recordmydesktop seems to be a write-only format.
First up, let me say this post has almost nothing to do with Ubuntu, so you may ask: Then why am I here? I am here because I didn't know where else to turn.
My main problem here is that I would like to be able to record myself playing a video game on my TV, and be able to toss the file onto my computer to edit/upload. I've heard of 'Dazzle' those TV recorder things, but I'm looking for more of a home quickfix.
What I was thinking of doing was hooking up a DVD player to a tv. Then hooking up my wii to the DVD player, to the TV. This way the game would be displayed on channel three. If I were to do this, would I be able to put a blank DVD in the drive, and set it to record channel three? Since channel three will be my game, would it record the video game? I'm sure if it would, it wouldn't be the best quality.
I'm trying to record music playing on my computer with the sound recorder/audacity but there is nothing audible being recorded. I've installed PulseAudio Volume control and selected monitor of internal analog stereo. I can't figure out if I have an output/input incorrectly selected but maybe someone could take a look at the screenshots and provide feedback! I have a dell xps 8100
I posted my question on Linx.com, but have not received an answer after 75 viewers to my question: Ok my respected Linux genius. This is my project. First I have a Windows / Linux combo OS set-up! In my windows, I use the latest realtex sound driver as this gives me complete control with recording output control and Microphone gain control. In the set-up, there is a stereo mixer component with is necessary to engage the direct sound recording from my sound card. To make this all come together, I use a sound recording software [ free sound recorder 9 ] and to convert the recording to a wma, wav, or meg, I use Roxio 10 to produce audio cd's to play on all CD Players.
The challenge for me in Linux is to create the same set-up with Linux applications to produce the same professional results.Presently, my kubuntu 10.04 has Alsa sound drivers, with a version of realtek incorporated. I have the Alsa mixer software as well as Audacity as the sound recorder program. But no matter what I do, audacity depends on the microphone to record, which makes the final recording pure crap. If I lower the microphone boost or gain in my Alsa mix, then Audacity can not record the ambient sound from the speaker output and it will only recognize mono and pulse as the sound method. With the pre mention set up, Who has a set up identical to what is offered to windows that will do exactly the same for Linux. I basically want to record directly from the sound card in my Linux, without depending on using my microphone and then a CD burning program to make the conversion to MPEG or the necessary file format for the burned CD to play in all CD players, not just on a PC) I am trying to stay away from command line language in the terminal. I really need a replacement for Audacity,cause Free Sound Recorder is made for Windows Platform......I need a Linux sound Guru for the answer.I am not doing this to pirate music....I have over 3,450 music track inside my Rhapsody subscription and I like to record music for personal listening on my portable CD player and at 0.99 per track charge to do this in Rhapsody, I might as well by a recording studio and hire the singing artist.Basically in short..I need to know if there is a setting I can engage in my Alsa Mixer panel that will allow me to record directly from my sound card without using my microphone as a default. When I mute the microphone in my Alsa control panel, my Audacity program will not record using the microphone, which I do not want to use anyway. I just want to record straight from my sound card, as this eliminates all hiss, distortion that is inherited with using a microphone.
Can I run this camera: Quote: Bus 001 Device 007: ID 046d:0809 Logitech, Inc as something other than a UVC driven camera? It appears that UVC in 640x480 format is only available at 15 fps. I need to record at fps=30. So I can splice into existing video.
[Code]...
echo "Recording. Ctrl-C or close window to stop" Is there a driver other than 'v4l2' I can use that will give me 30 frames per second?
how can I adjust the volume level while recording audio playback and microphone at the same time? I managed to increase the audio playback volume with PulseAudio Volume Control (Input devices -> Monitor of Internal Audio Analog Stereo -> pressing green button "Set as fallback"), but once I click on that green button, no no microphone sound is recorded.
Details:
- using Ubuntu 10.04 LTS - recording audio with Sound Recorder - installed PulseAudio Device Choooser and PulseAudio Volume Control - Input devices -> Internal Audio Analog Stereo --> shows the sound from microphone
[code]...
- how to adjust volume of audioplayback and microphone recording and record both as a mix together? Thanks!
PS: I checked out this thread, but haven't figured out how to adjust the volumes.
I'm trying to capture audio from a stream, NOT from the mic. This is what I'm doing: Start Audacity, push its record button, play a song. It shows that it is recording but when I play back the results, all background noise, conversation, etc, is in the recording as well as the audio from the song. If the mic is unplugged, I cannot record what I hear coming from the sound card (as in what you hear from the sound card is what you get). I got directions on how to do what I want here ( Looking (maybe) for audio mixer for use with Pulse Audio - Page 2 Posts # 4 and 5) but it's not permanent. I got the instructions in post #11 from that same page to make such a change permanent. I tried using the instructions to make the change permanent (I backed up my default.pa just in case something went wrong) and these are the changes I had made:
Code:
### Load audio drivers statically (it's probably better to not load ### these drivers manually, but instead use module-hal-detect -- ### see below -- for doing this automatically) #load-module module-alsa-sink
Inspired by some recent posts from oldcpu I decided to grab some audio from my Logitech webcam, just for the fun of it. openSUSE 11.3 i586 is in use.
Code: > lsusb Bus 002 Device 003: ID 046d:0991 Logitech, Inc. QuickCam Pro for Notebooks > arecord -l **** Liste der Hardware-Geräte (CAPTURE) **** Karte 0: Intel [HDA Intel], Gerät 0: ALC892 Analog [ALC892 Analog]
[Code]...
It works! Though I have to say that the audio quality is mediocre (to say the best). I blame it on the quality of the built-in microphone of this camera. It sounds like it was recorded in a giant bathroom.
I'm trying to record some audio from 4-track cassette tapes using Audacity and a Sound Blaster mp3+ external usb audio card.I'm using Karmic.I have fiddled with levels on the sound card using alsamixer, but the only I way I can detect any sound from the tapes when recording is by turning the levels all the way up in alsamixer, and in doing this, I can faintly make out the audio beneath a large wall of static. If the levels are not maxed out, I only get static when recording in Audacity.
I have detected some problems when I try to record sound in my Kubuntu 10.04 system.
The problem is that the "default" device for audio recording does not work but I have to select another device to do so. I always selected the "default" device for audio recoding but currently I have to select hw:0,2 device.
Another odd thing is that different programs show me different device. For example, Audacity shows me that I have the following audio recording devices:
- HDA Intel: ALC888 Digital (hw:0,1) - HDA Intel: ALC888 Analog (hw:0,2) - spdif - default
The only one that works is hw:0,2.
But arecord shows me (when I execute "arecord -L") the following:
Finally, in KDE system preferences for audio I get that I have 2 different audio devices for audio recording:
- HDA Intel (ALC888 Analog): it is said that it will try first x-phonon (CARD=0, DEV=0) and, if the latter does not work, it will try plughw (CARD=0, DEV=0)
- HDA Intel (ALC888 Digital): it is said that it will try first x-phonon (CARD=0, DEV=1) and, if the latter does not work, it will try plughw (CARD=0, DEV=1)
Where is the hw:0,2? and how can I set the alsa system to use hw:0,2 as the default device for audio recording?
All of that would not be a problem but I also have an ubuntu 9.04 installed on a virtual machine (by using virtualbox) and audio recording doesn't work there. I suppose that it is becase of the virtual sound card is using default devices for playing and recording audio.
I must say that audio playback works fine in both host and guest systems. It is just audio recording.
For some reason Java Applications running through Firefox have no audio, Java applications running through the java -jre command do run with working audio though. I don't know what else I need to post, but this is what I've been getting. Audio does seem to work with most of my other applications and games.
I'm sure this is a painfully naive question, but I don't suppose it can possibly lower my reputationFor Good Reasons,use a custom build of the audio editor audacity rather than the version in the openSUSErepositories. What I can't seem to figure out is how to get it to find and load the LADSPA signal processing plug-ins. I have the regulation ladspa libraries (1.13-6.2) from the Oss repository installed. The files reside at /usr/lib64/ladspa . audacity is built with ladpsa support enabled, and indeed reports that it is enabled if I look at the Effects tab under preferences. I have even entered the ladspa library path in a "ladspa.conf" file under /etc/ld/so.conf.d, which may or may not help. Regardless, I don't seem to see the ladpsa effects listed when I run audacity
Or at least that's what I figured, when watching videos from ....., etc., the sound in the left channel turns into distorted high frequency noise, anyone had the same issue? Is there a fix for this? Sound in other applications works just fine.EDIT: Oh, and I'm using the proprietary flash plugin, has worked just fine on my Ubuntu Studio on the exact same computer.
I don't understand what is going on... If I listen music, the sounds quality is just perfect, but if I play quakelive, I start heard some annoying noises such as my headphone wire is damaged. how to remove it? Maybe something wrong with sound drivers? I use ubuntu 10.04 LTS version OS. Sound card is realtek (integrated to motherboard).
Setting up a linux based church server to be placed with a collocation host.
-- Server will be used for: --- providing .pdf files --- live streaming of church services (audio for now audio video soon) --- providing audio files --- providing audio-video files --- our internet web site
A. Is there a preferred Linux distribution that will make this easier?
B. What is the best format for audio and video files that will be viewed variously on Linux, Mac, and Microsoft operating systems? Files will need to be played on older versions of operating systems and may need a free or very low cost software to play (e.g. play on Win2k)
C. What software is best for recording the audio or audio-video files? Some additional funding might be justified for this software, particularly if it can also support live streaming.
D. What software is best for live streaming both on the file creation and the listening-viewing sides of the process?
Ideally we would like to have a single software suite to live stream, and make downloadable audio or audio-video files for later download, and not require those listening and viewing to have to install additional software. Keeping file sizes small is also desirable because some of our users will probably only have dial-up internet.
I am currently running Ubuntu 9.04 and am looking at upgrading to the upcoming 10.04 LTS release. And have been trying out the new version using the release candidate live CD. The main problem is one that was also evident when 9.04 was originally installed - audio recording and monitoring simply is not working. With 9.04 it took several hours of head-banging and reading HOW-TOs and guides to get to the point where audio input to the sound card played through the speakers and can be recorded by programs such as Audacity.
I've been trying to poke around with 10.04 to get the same results and so far had no success. (Things have changed sufficiently that it does not seem straightforward to simply replicate my 9.04 settings.) This is on 64-bit Ubuntu with a Soundblaster Audigy sound card. It's a little disappointing that we are not yet at the point where this type of basic functionality is working "out of the box" with Ubuntu. Anyone have any tips to setting up 10.04 for audio recording and monitoring?
Although I never did get this working with the live CD, recording worked fine after doing a test installation of Lucid on a spare hard drive. With the live CD the primary line input was not even showing up in alsamixer. With Lucid installed it was no problem to find and crank up the volume on this input. In actuality then, once the installation was actually done it took much less fiddling with this release than it did with 9.04 to get the same results.
I want to record conversations and stuff from skype. Now, I want the sound to be as good as possible, so what settings do I choose, what do I mute and all the other volume combinations and settings do I configure etc... To get the best record possible, I need to record from both pc and mic at the same time, but how? As my settings are now I can only record through the mic. So, what do I do? Also, if you could give me a few tips on how I can filter useless background noise.
I would like to remove the audio tracks from various video clips (.avi, .mpg. .wmv, .flv, etc.).I Googled and found lots of ways to strip off the audio and save that sound as an mp3 file, but I have found nothing that would allow me to remove the audio and save my video clip (silently)
i am trying to use Audacity to record internally the sound playing on my computer, and im finding the program quite confusing. I have found that by connecting the line out to the line in i am able to record, but the quality is rubbish, it will be a lot smoother recording it internally but I cant find a way of doing this, does anyone know how to record that way or know where i'm going wrong?
I am using a PC to telnet into a Lucid Lynx Ubuntu system, and trying to record audio via a microphone which is connected to the Ubuntu system, and play it back on the PC. The microphone works when recording and playing directly on the Ubuntu system (so I know it's not hardware), but not when recording over the telnet connection. Playing other audio files does work over the telnet connection (so once again, I know it's not hardware), it's just the recording that doesn't work.
So basically it's just the audio-in over the telnet connection that Ubuntu isn't liking.
I tried removing PulseAudio (as I had a Fedora system that I had to do this with also, and that was the fix for that system), but apparently recording doesn't work at all in Ubuntu without it, as the microphone wouldn't work directly on the system anymore after in removed it. So I reinstalled it, but I am still stuck.
I cannot use any other programs to accomplish this - and I don't think I have to, I believe something is just messed up somewhere that is not allowing my microphone to pick up sound over the telnet connection, but I don't know what it is.
I'm using audacity to record some songs and it works okay. However I use a Samson Go usb mic to pick up vocals and guitar, and i have a line out straight from my guitar. I can record from either by choosing which sound input I want to use in the Ubuntu sound preferences but I wanted to know if there was anyway I could select both and record both mic and jack simultaneously, is this possible??
I hear Pulse Audio is the culprit of all the sound issues. I would like to remove it, and default to straight ALSA or whatever distros like Fedora and Ubuntu use, which has never been problematic for me.
I have recently grown to love Linux for its fast reliable virus free and clean uncluttered operation for word, photo, spreadsheet and especially internet use. As a pro musician I've used Sonar on Windows XP for years and it's a great programme, however for various reasons I would like to abandon Windows completeley and I like Audacity, Ardour and Rosegarden. Although basic, these would get me through most of my projects as a guitar teacher. My questions are: is it considered essential to install a real-time kernel or can you get by nudging audio by 50 ms or so. Ubuntu Studio would be the answer I guess although on my HP dual core I get mouse and keyboard freezes with Ubuntu after 9.04! - weird. Fedora has always been rock solid on my machines although I understand that there is no real time package for versions after F12. Are there musicians out there that use Fedora? - which versions and what set up.
So I work off and on doing live sound work and I am interested in starting to record some of the shows I work on. Naturally I only run Linux based operating systems on my computers so I was wondering if anyone could recommend a good piece of hardware for recording 8-16 tracks that fully supports Linux. I have firewire and USB interfaces on my studio laptop.
I am currently dual booting Linux and Windows XP. On XP I use Adobe Audition (similar to Cubase) for Audio Recording and editing. It works well. But it is a pain to have XP just for this single task. If I installed XP in Virtualbox on Linux, and did my recording through that, would I have latency or other issues?
My Computer has a 2.2Ghz Core2Duo 64-bit with VT-x and 4GB of Ram.
I know about Ardour and other recording programs for Linux. In this case, I need to use this Windows only program. Sadly.
