  • Dell Vostro 1000 audio and wireless NIC drivers

    - by Ssvarc
    I have a Dell Vostro 1000 laptop with a fresh XP Pro install. I'm trying to track down the correct audio and wireless NIC drivers. I've used this Dell support driver page, but the drivers it gives for the service tag and XP OS don't work. Anyone have links to the correct, working drivers?

  • Alternatives to musicbrainz picard -audio-fingerprinting tagging services [closed]

    - by Journeyman Geek
    Possible Duplicate: Auto-tagging MP3s I'm currently using musicbranz picard to tag files that don't have any usable tagging information. For some reason, currently none of the files I trying to ID seem to be identified, despite some of them them being artists who are almost certainly on musicbrainz. So, I'm looking for something that uses an alternate database and does the same thing - to identify unknown music files off an audio fingerprint. Windows is preferred, but I would be fine with any of the big 3 OSes (Windows/Linux/OS X).

  • good player to use for audio books

    - by doug
    Hi there i just find that is useful to listen audio books, but when it is about tacking notices, the play/pause, adding bookmarks is impossible with the regular players(windows media player, vlc, bsplayer, winamp). Do you know a better alternative to that?

  • Software that will extract the individual audio channels from a WMA file

    - by typoknig
    I have a 6 channel WMA file and I would like to extract each of those 6 channels into its own mono WAV file. This is a simple task with AC-3 audio files, but apparently not with WMA. I could re-encode the WMA as an AC-3 then extract the streams, but I want lossless solution. Please only confirmed solutions. I have put a lot of time into searching for a solution and have had my fill of "try this" and "this might work".

  • Streaming audio/video in a publicly-hosted server increases bandwith usage

    - by Eka
    I have a website hosted in a public server (withoud any streaming content) ,using public hosting instead of private because its cheaper. But in public hosting their are limitations when compared to private hosting such as monthly bandwidth usage (1 GB), disk space, cpu usage etc. I am planning to embedd videos and audios (from other websites like youtube) to my already existing website. My question is if a client streams a embedded video/audio (hosted in another website) from my website any change in bandwidth occurs.

  • How to right click and play audio folder on Windows Media Player 12

    - by Mehper C. Palavuzlar
    It's always been hard for me to add a music folder with subfolders to Windows Media Player's playlist. I double click a file in the folder (or click on WMP shortcut), WMP opens, and I drag the other files or folders manually to the playlist. Isn't there an option to add a right-click context menu item that can automatically add all audio contents in a folder (with subfolders) to WMP playlist?

  • linearRGB conversion to/from HSL

    - by Otaku
    Does anyone know of a way to get HSL from an linearRGB color (not an sRGB color)? I've seen a lot of sRGB<-HSL conversions, but nothing for linearRGB<-HSL. Not sure if it is fundementally the same conversion with minor tweaks, but I'd appreciate any insight someone may have on this. Linear RGB is not the same as linearizing sRGB (which is taking [0,255] and making it [0,1]). Linear RGB transformation from/to sRGB is at http://en.wikipedia.org/wiki/SRGB. In VBA, this would be expressed (taking in linearized sRGB values [0,1]): Public Function sRGB_to_linearRGB(value As Double) If value < 0# Then sRGB_to_linearRGB = 0# Exit Function End If If value <= 0.04045 Then sRGB_to_linearRGB = value / 12.92 Exit Function End If If value <= 1# Then sRGB_to_linearRGB = ((value + 0.055) / 1.055) ^ 2.4 Exit Function End If sRGB_to_linearRGB = 1# End Function Public Function linearRGB_to_sRGB(value As Double) If value < 0# Then linearRGB_to_sRGB = 0# Exit Function End If If value <= 0.0031308 Then linearRGB_to_sRGB = value * 12.92 Exit Function End If If value < 1# Then linearRGB_to_sRGB = 1.055 * (value ^ (1# / 2.4)) - 0.055 Exit Function End If linearRGB_to_sRGB = 1# End Function I have tried sending in Linear RGB values to standard RGB_to_HSL routines and back out from HSL_to_RGB, but it does not work. I have seen almost no references that this can be done, except for two: A reference on http://en.wikipedia.org/wiki/HSL_and_HSV#cite_note-9 (numbered item 10). A reference on an open source project Grafx2 @ http://code.google.com/p/grafx2/issues/detail?id=63#c22 in which the contributor states that he has done Linear RGB <- HSL conversion and provides some C code in an attachment to his comment in a .diff file (which I can't really read :( ) My intent is to send from sRGB (for example, FF99FF (R=255, G=153, B=255)) to Linear RGB (R=1.0, G=0.318546778125092, B=1.0) using the code above (for example, the G=153 would be obtained in Linear RGB from sRGB_to_linearRGB(153 / 255)) to HSL, modify the Saturation by 350% and going back from HSL-Linear RGB-sRGB, the result would be FF19FF (R=255, G=25, B=255). Using available functions from .NET, such as .getHue from a System.Drawing.Color does not work in any sRGB space above 100% modulation of any HSL value, hence the need for Linear RGB to be sent in instead of sRGB.

  • How does one convert 16-bit RGB565 to 24-bit RGB888?

    - by jleedev
    I’ve got my hands on a 16-bit rgb565 image (specifically, an Android framebuffer dump), and I would like to convert it to 24-bit rgb888 for viewing on a normal monitor. The question is, how does one convert a 5- or 6-bit channel to 8 bits? The obvious answer is to shift it. I started out by writing this: uint16_t buf; while (read(0, &buf, sizeof buf)) { unsigned char red = (buf & 0xf800) >> 11; unsigned char green = (buf & 0x07c0) >> 5; unsigned char blue = buf & 0x003f; putchar(red << 3); putchar(green << 2); putchar(blue << 3); } However, this doesn’t have one property I would like, which is for 0xffff to map to 0xffffff, instead of 0xf8fcf8. I need to expand the value in some way, but I’m not sure how that should work. The Android SDK comes with a tool called ddms (Dalvik Debug Monitor) that takes screen captures. As far as I can tell from reading the code, it implements the same logic; yet its screenshots are coming out different, and white is mapping to white. Here’s the raw framebuffer, the smart conversion by ddms, and the dumb conversion by the above algorithm. (By the way, this conversion is implemented in ffmpeg, but it’s just performing the dumb conversion listed above, leaving the LSBs at all zero.) I guess I have two questions: What’s the most sensible way to convert rgb565 to rgb888? How is DDMS converting its screenshots?

  • rpm file conflict after alien conversion

    - by Zitrax
    I have a program for which I generate a .deb file. The .deb file works fine on the systems I have tried it on (also tested with lintian). Previously it has worked to use alien to convert this to .rpm and install it on Suse. However it is now about a year since I tried it the last time and now I get an error when trying to install the alien made rpm on Fedora 11, I get this error: file /usr/share/icons/default.kde from install of testpkg-0.2-2.i386 conflicts with file from package kdelibs3-3.5.10-13.fc11.1.i586 Listing the content of the rpm file: $ rpm -qlp testpkg-0.2-2.i386.rpm / /usr /usr/games /usr/games/testpkg /usr/lib /usr/lib/libfmod-3.75.so /usr/share /usr/share/app-install /usr/share/app-install/icons /usr/share/app-install/icons/testpkg.png /usr/share/applications /usr/share/applications/testpkg.desktop /usr/share/doc /usr/share/doc/testpkg /usr/share/doc/testpkg/changelog.gz /usr/share/doc/testpkg/copyright /usr/share/games /usr/share/games/testpkg /usr/share/games/testpkg/images /usr/share/games/testpkg/images/bb.dat /usr/share/games/testpkg/images/bb_bg.dat /usr/share/games/testpkg/images/bubblemad_8x8.png /usr/share/games/testpkg/images/goldfont.png /usr/share/games/testpkg/lvl /usr/share/games/testpkg/lvl/lvl001.txt /usr/share/games/testpkg/lvl/lvl002.txt /usr/share/games/testpkg/lvl/lvl003.txt /usr/share/games/testpkg/lvl/lvl004.txt /usr/share/games/testpkg/lvl/lvl005.txt /usr/share/games/testpkg/lvl/lvl006.txt /usr/share/games/testpkg/lvl/lvl007.txt /usr/share/games/testpkg/music /usr/share/games/testpkg/music/alfa.it /usr/share/games/testpkg/music/beta.it /usr/share/games/testpkg/sounds /usr/share/games/testpkg/sounds/bounce.wav /usr/share/games/testpkg/sounds/click.wav /usr/share/games/testpkg/sounds/warning.wav /usr/share/icons /usr/share/icons/default.kde /usr/share/icons/default.kde/16x16 /usr/share/icons/default.kde/16x16/apps /usr/share/icons/default.kde/16x16/apps/testpkg.png /usr/share/man /usr/share/man/man6 /usr/share/man/man6/testpkg.6.gz Am I wrong in putting the kde icons in /usr/share/icons/default.kde which seem to be a symbolic link ? It's a symbolic link on both Kubuntu 9.10 and Fedora 11 though. Sounds like a common situation that the same directory is needed for different packages, so why is it a conflict ?

  • CentOS 5.5 ext4 conversion problem - ext4 partition is recognized as ext3

    - by FractalizeR
    Hello. I had 5.4 machine. Upgraded to 5.5 today via yum upgrade. All went fine. Rebooted. Wanted to convert root partition to ext4 (I have three partitions: /boot, / and swap). All of them on software RAID 1 (root is /dev/md2). I did the following for converting yum install e4fsprogs tune2fs -O extents,uninit_bg,dir_index /dev/md2 nano /etc/fstab # I indicated here that my /dev/md2 is of ext4 uname -a mkinitrd -f /boot/initrd-2.6.18-194.3.1.el5.img 2.6.18-194.3.1.el5 Rebooted. I expected fsck to start automatically as said on some site. But it did not. Threw some error (don't remember exactly which). Ok, I booted linux rescue and executed fsck: fsck -t ext4 -fy /dev/md2 Partition went fine. But still when I boot main system, it says in log: "ext3-fs:" then something about not being able to mount ext3 partition due to unknown extended attributed (200). I booted linux rescue again. It loads fine and correctly determines all my machine partitions both ext3 (boot) and ext4 (/) under /mnt/sysimage just fine. I retried mkinitrd thing again watching it's output and ensured ext4 module is included into the system. I also edited menu.lst grub file to include rootfstype=ext4 kernel parameter. Bad luck. I still have message from ext3-fs about not being able to mount filesystem because of attributes and kernel panic immediately after. I checked /etc/fstab - it's fine and saying that root is of ext4. What did I do wrong? This machine is empty so I can just reformat it with 5.5 and recreate partitions to be originally ext4. But... I just want to know what did I do wrong.

  • Any screen capture software that captures webcam, microphone inputs too ?

    - by mohanr
    I am going to conduct a user study. Apart from capturing the screen while the user is interacting with the system, I also want to capture the video/audio of the user. Is there any software that in addition to capturing the screen also overlays it with the webcam/microphone inputs. The goal is to capture the complete experience of the user: key/mouse interactions with the system along with their facial/vocal responses. I know that I can maybe run a screen-capture software and also run a software for capturing webcam audio/video alongside and try to sync/overlay both these streams with timestamps. But I am going to be dealing with probably several hundred hours of data. So I am looking for a tool that can streamline the process for me amap and help me keep my sanity at end of the process. Thanks,

  • SVG to JPEG/BMP conversion

    - by stanigator
    I have a svg file that I want to convert to jpeg or bmp (or any other image formats). However, all the conversions that I have used on the various online tools yielded very unclear output images. I don't want to use svg as it is very inconvenient. What would be your suggestions to get around that?

  • How do I set up live audio streams to a DLNA compliant device?

    - by Takkat
    Is there a way to stream the live output of the soundcard from our 12.04.1 LTS amd64 desktop to a DLNA-compliant external device in our network? Selecting media content in shared directories using Rygel, miniDLNA, and uShare is always fine - but so far we completely failed to get a live audio stream to a client via DLNA. Pulseaudio claims to have a DLNA/UPnP media server that together with Rygel is supposed to do just this. But we were unable to get it running. We followed the steps outlined in live.gnome.org, this answer here, and also in another similar guide. As soon as we select the local audio device, or our GST-Launch stream in the DLNA client Rygel displays the following message and the client states it reached the end of the playlist: (rygel:7380): Rygel-WARNING **: rygel-http-request.vala:97: Invalid seek request This is how we configured GST-Launch in rygel.conf: [GstLaunch] enabled=true launch-items=mypulseaudiosink mypulseaudiosink-title=Audio on @HOSTNAME@ mypulseaudiosink-mime=audio/x-wav mypulseaudiosink-launch=pulsesrc device=<device> ! wavpackenc For <device> we tried with the default sink name, this name appended with .monitor, and in addition with upnp-sink and upnp.monitor that was created when we selected DLNA media server from paprefs. We also tried to encode using lamemp3enc with no luck. These are our pulseaudio modules: http://paste.ubuntu.com/1202913/ These are our sinks: http://paste.ubuntu.com/1202916/ Did we miss any other additional configuration needed to get this running? Are there any other alternatives for sending the audio of our soundcard as live stream to a DLNA client?

  • How do you play or record audio (to .WAV) on Linux in C++? [closed]

    - by Jacky Alcine
    Hello, I've been looking for a way to play and record audio on a Linux (preferably Ubuntu) system. I'm currently working on a front-end to a voice recognition toolkit that'll automate a few steps required to adapt a voice model for PocketSphinx and Julius. Suggestions of alternative means of audio input/output are welcome, as well as a fix to the bug shown below. Here is the current code I've used so far to play a .WAV file: void Engine::sayText ( const string OutputText ) { string audioUri = "temp.wav"; string requestUri = this->getRequestUri( OPENMARY_PROCESS , OutputText.c_str( ) ); int error , audioStream; pa_simple *pulseConnection; pa_sample_spec simpleSpecs; simpleSpecs.format = PA_SAMPLE_S16LE; simpleSpecs.rate = 44100; simpleSpecs.channels = 2; eprintf( E_MESSAGE , "Generating audio for '%s' from '%s'..." , OutputText.c_str( ) , requestUri.c_str( ) ); FILE* audio = this->getHttpFile( requestUri , audioUri ); fclose(audio); eprintf( E_MESSAGE , "Generated audio."); if ( ( audioStream = open( audioUri.c_str( ) , O_RDONLY ) ) < 0 ) { fprintf( stderr , __FILE__": open() failed: %s\n" , strerror( errno ) ); goto finish; } if ( dup2( audioStream , STDIN_FILENO ) < 0 ) { fprintf( stderr , __FILE__": dup2() failed: %s\n" , strerror( errno ) ); goto finish; } close( audioStream ); pulseConnection = pa_simple_new( NULL , "AudioPush" , PA_STREAM_PLAYBACK , NULL , "openMary C++" , &simpleSpecs , NULL , NULL , &error ); for (int i = 0;;i++ ) { const int bufferSize = 1024; uint8_t audioBuffer[bufferSize]; ssize_t r; eprintf( E_MESSAGE , "Buffering %d..",i); /* Read some data ... */ if ( ( r = read( STDIN_FILENO , audioBuffer , sizeof (audioBuffer ) ) ) <= 0 ) { if ( r == 0 ) /* EOF */ break; eprintf( E_ERROR , __FILE__": read() failed: %s\n" , strerror( errno ) ); if ( pulseConnection ) pa_simple_free( pulseConnection ); } /* ... and play it */ if ( pa_simple_write( pulseConnection , audioBuffer , ( size_t ) r , &error ) < 0 ) { fprintf( stderr , __FILE__": pa_simple_write() failed: %s\n" , pa_strerror( error ) ); if ( pulseConnection ) pa_simple_free( pulseConnection ); } usleep(2); } /* Make sure that every single sample was played */ if ( pa_simple_drain( pulseConnection , &error ) < 0 ) { fprintf( stderr , __FILE__": pa_simple_drain() failed: %s\n" , pa_strerror( error ) ); if ( pulseConnection ) pa_simple_free( pulseConnection ); } } NOTE: If you want the rest of the code to this file, you can download it here directly from Launchpad.

  • Voices disappear when using headphones.

    - by James
    How do I declare a variable in C? P.S. I have a pair of SteelSeries Siberia headphones. I've noticed that when watching some films the voices are completely silent, yet when I unplug the headset and listen through my speakers they are there and sound normal. I have no other software that could be interfering with it and it happens regardless of the software I use for playback (I've tried VLC, WMP and Quicktime). It is so strange, and it almost sounds deliberate - the rest of the audio is untouched but voices disappear. The films only have single audio tracks, and it doesn't happen with every film. Can anyone give me any hints as to what could possibly cause this? I am stumped!
