• What are my audio devices?

  - by hellocatfood

  I'm attempting to use easycap to record from my camcorder but I'm having a slight problem. Using their test script I'm able to get audio and video. I've noticed that in the script on line 159 it makes a call to "DEV_ADUIO", which is reported as being "plughw:2,0". Exactly what is this device? Is it located in /dev/ somewhere? I've done "ls /dev/" and I can't find anything that would suggest an audio device

• How to convert image to CMYK in GIMP?

  - by edm

  I am supposed to send some artwork to the printers tomorrow and their guidelines requires it to be CMYK. I have installed the plugin Separate+ from the 'gimp-plugin-registy' package. I have also installed some ICC colour profiles from the 'icc-profiles' package. When I try to use the Separate+ plugin all I can get it to output is an image that looks like the original but with the colours inverted. How can I convert my image to CMYK?

• How to find an audio file's length (in seconds)

  - by mIL3S

  Hi all! (Objective C) Just using simple AudioServicesPlaySystemSoundID and its counterparts, but I can't find in the documentation if there is already a way to find the length of an audio file. I know there is AudioServicesGetPropertyInfo, but that seems to return a byte-buffer - do audio files embed their length in themselves and I can just extract it with this? Or is there perhaps a formula based on bit-rate * fileSize to convert to length-of-time? mIL3S www.milkdrinkingcow.com

• SEHException throw using Microsoft XACT Audio Framework (XACT3)

  - by Sweta Dwivedi

  I have been developing a game using Kinect + XNA and using Microsoft Audio Creation tool (XACT3) for managing my sound files and music, however in the code an SEHException is thrown whenever it tries to get the wave file from the wave Bank . . Sometimes the code works magically and all of a sudden it will start throwing this exception randomly ..I need a help on solving this exception /*Declaring Audio Engine for music*/ AudioEngine engine; SoundBank soundBank; WaveBank waveBank; Cue cue; /*Declaring Audio engine for sound effects*/ AudioEngine engine1; SoundBank soundbank; WaveBank wavebank; Cue effect; engine = new AudioEngine(@"Content\therapy.xgs"); soundBank = new SoundBank(engine, @"Content\Sound Bank.xsb"); **waveBank = new WaveBank(engine, @"Content\Wave Bank.xwb");** cue = null; engine1 = new AudioEngine(@"Content\Music_Manager\Sound_effects.xgs"); soundbank = new SoundBank(engine1, @"Content\Music_Manager\Sound1.xsb"); **wavebank = new WaveBank(engine1, @"Content\Music_Manager\Wave1.xwb");** effect = null; cue = soundBank.GetCue("hypnotizing"); cue.Play();

• SQL Full-Text indexing not populating

  - by Sam

  Hi, We installed a clustered SQL 2005 installation on windows 2008 and reattached our san drives from another machine and restored to do a migration to new hardware.

• Question SpeechSynthesizer.SetOutputToAudioStream audio format problem

  - by Chris Kugler

  Hi, I'm currently working on an application which requires transmission of speech encoded to a specific audio format. System.Speech.AudioFormat.SpeechAudioFormatInfo synthFormat = new System.Speech.AudioFormat.SpeechAudioFormatInfo(System.Speech.AudioFormat.EncodingFormat.Pcm, 8000, 16, 1, 16000, 2, null); This states that the audio is in PCM format, 8000 samples per second, 16 bits per sample, mono, 16000 average bytes per second, block alignment of 2. When I attempt to execute the following code there is nothing written to my MemoryStream instance; however when I change from 8000 samples per second up to 11025 the audio data is written successfully. SpeechSynthesizer synthesizer = new SpeechSynthesizer(); waveStream = new MemoryStream(); PromptBuilder pbuilder = new PromptBuilder(); PromptStyle pStyle = new PromptStyle(); pStyle.Emphasis = PromptEmphasis.None; pStyle.Rate = PromptRate.Fast; pStyle.Volume = PromptVolume.ExtraLoud; pbuilder.StartStyle(pStyle); pbuilder.StartParagraph(); pbuilder.StartVoice(VoiceGender.Male, VoiceAge.Teen, 2); pbuilder.StartSentence(); pbuilder.AppendText("This is some text."); pbuilder.EndSentence(); pbuilder.EndVoice(); pbuilder.EndParagraph(); pbuilder.EndStyle(); synthesizer.SetOutputToAudioStream(waveStream, synthFormat); synthesizer.Speak(pbuilder); synthesizer.SetOutputToNull(); There are no exceptions or errors recorded when using a sample rate of 8000 and I couldn't find anything useful in the documentation regarding SetOutputToAudioStream and why it succeeds at 11025 samples per second and not 8000. I have a workaround involving a wav file that I generated and converted to the correct sample rate using some sound editing tools, but I would like to generate the audio from within the application if I can. One particular point of interest was that the SpeechRecognitionEngine accepts that audio format and successfully recognized the speech in my synthesized wave file... Update: Recently discovered that this audio format succeeds for certain installed voices, but fails for others. It fails specifically for LH Michael and LH Michelle, and failure varies for certain voice settings defined in the PromptBuilder.

• Method extension for safely type convert

  - by outcoldman

  Recently I read good Russian post with many interesting extensions methods after then I remembered that I too have one good extension method “Safely type convert”. Idea of this method I got at last job. We often write code like this: int intValue; if (obj == null || !int.TryParse(obj.ToString(), out intValue)) intValue = 0; This is method how to safely parse object to int. Of course will be good if we will create some unify method for safely casting. I found that better way is to create extension methods and use them then follows: int i; i = "1".To<int>(); // i == 1 i = "1a".To<int>(); // i == 0 (default value of int) i = "1a".To(10); // i == 10 (set as default value 10) i = "1".To(10); // i == 1 // ********** Nullable sample ************** int? j; j = "1".To<int?>(); // j == 1 j = "1a".To<int?>(); // j == null j = "1a".To<int?>(10); // j == 10 j = "1".To<int?>(10); // j == 1 Read more...

• How to create a text file from column and FTP that text file to server

  - by addi

  I have workbook with 2 sheets (Sheet1 and sheet2). On sheet1 user will enter the data which will be populated in the column B and then column C will hold the values from Col A and B on sheet2. I need to create a text file from the values in coloumn C on a click of a button and then upload(FTP) that file to a server. So the sheet1 will have 2 buttons. Button1 will save the excel file and create the text file in windows temp directory. e.g text.xls text.prop (text file whoch has all the values in column C on sheet2) Button2 will upload (FTP) the text file (.prop) to a server. Can anyone please send me the steps and VB code to achieve the above tasks? Thanks in Advance Addi

• Physics-based dynamic audio generation in games

  - by alexc

  I wonder if it is possible to generate audio dynamically without any (!) audio assets, using pure mathematics/physics and some input values like material properties and spatial distribution of content in scene space. What I have in mind is something like a scene, with concrete floor, wooden table and glass on it. Now let's assume force pushes the glass towards the edge of table and then the glass falls onto the floor and shatters. The near-realistic glass destruction itself would be possible using voxels and good physics engine, but what about the sound the glass makes while shattering? I believe there is a way to generate that sound, because physics of sound is fairly known these days, but how computationaly costy that would be? Consumer hardware or supercomputers? Do any of you know some good resources/videos of such an experiment?

• Playing part of a sfx audio file in HTML5 using WebAudio

  - by Matthew James Davis

  I have compiled all of my sound effects into one sequenced .ogg file. I have the start and stop times for each sound effect. How do I play the individual effects? That is, how do I play part of an audio file. More specificially, I've created a dictionary { 'sword_hit': { src: 'sfx.ogg', start: 265, // ms length: 212 // ms } } that my play_sound() function can use to look up 'sword_hit' and play the correct audio file at the correct start time for the correct duration. I simply need to know how to tell the WebAudio API to start playing at start ms and only play for length ms.

• mplayer (mplayerhq.hu) repeats ending audio frames

  - by kamikatze

  mplayer (from mplayerhq.hu) on windows repeats the last few audio frames upon exit. When the video ends, before you can see Exiting...

• No audio input deviced are installed

  - by Meowbits

  If I go to Sound Recording Devices and it says "No audio devices are installed" If I click to set up a microphone I get an error "Wizard could not launch, No audio input device found, make sure your audio hardware is working properly and check your audio configuration in the Audio Devices and Sound Themes control panel. Where can I get an audio input device? I just want something so I can actually use the microphone on my headset. This is ridiculous. I have tried to look for any file but I simply cannot find a way to add an audio input device... I really do not want to format my computer just for this problem but I am starting to feel like that is the only option I have. I have the latest chipsets

• How can I split a stereo audio track of a movie into two separate audio tracks?

  - by pesche

  I often record TV shows with a hard disk recorder/DVD writer, burn them as VRO file and convert to MP4 with Handbrake. The shows are bilingual broadcasts with two mono audio channels instead of a stereo one: dubbed voice on the left, original voice on the right. The TV set and VLC are both perfectly capable to play only the left or the right channel, but other video players may just offer to select between different stereo audio tracks (like they are present on many DVDs). I'd like to have an easy process to create MP4 or MKV files of these shows where the two audio channels are split into two separate audio tracks. The only way that I know of is to extract the audio track (e.g. using MPEG Streamclip), split it into two tracks using an audio tool like Audacity and then merge the audio tracks back (using a DVD authoring software, don't remember all details). Clearly not a thing to repeat regularly. Preferably a solution should run on Mac OS X, but Linux or Windows solutions are very welcome, too.

• iPhone SDK: Change playback speed using core audio AVAudioPlayer

  - by Harkonian

  I'd like to be able to play back audio I've recorded using AVAudioRecorder @ 1.5x or 2.0x speed. I don't see anything in AVAudioPlayer that will support that. I'd appreciate some suggestions, with code if possible, on how to accomplish this with the iPhone 3.x SDK. I'm not overly concerned with lowering the pitch to compensate for increased playback speed, but being able to do so would be optimal.

• Video and Audio Drift

  - by Cenoc

  Hey everyone, I was wondering, how much does recorded audio and video drift from their actual recording time usually? I'm recording both separately (into unsigned 8 bit PCM (44100 Hz) and raw image data files) and I was wondering how much I can expect each to drift. Thanks in advance!

  Hey, I was wondering, what was a good cross-platform utility for doing audio recording/ playback/ seeking in C++? I was thinking going the route of ALUT (OpenAL), but is there a better way? If not, do you guys know of any good tutorials/sample code for ALUT?

• Redaction in AutoVue

  - by [email protected]

  As the trend to digitize all paper assets continues, so does the push to digitize all the processes around these assets. One such process is redaction - removing sensitive or classified information from documents. While for some this may conjure up thoughts of old CIA documents filled with nothing but blacked out pages, there are actually many uses for redaction today beyond military and government. Many companies have a need to remove names, phone numbers, social security numbers, credit card numbers, etc. from documents that are being scanned in and/or released to the public or less privileged users - insurance companies, banks and legal firms are a few examples. The process of digital redaction actually isn't that far from the old paper method: Step 1. Find a folder with a big red stamp on it labeled "TOP SECRET" Step 2. Make a copy of that document, since some folks still need to access the original contents Step 3. Black out the text or pages you want to hide Step 4. Release or distribute this new 'redacted' copy So where does a solution like AutoVue come in? Well, we've really been doing all of these things for years! 1. With AutoVue's VueLink integration and iSDK, we can integrate to virtually any content management system and view documents of almost any format with a single click. Finding the document and opening it in AutoVue: CHECK! 2. With AutoVue's markup capabilities, adding filled boxes (or other shapes) around certain text is a no-brainer. You can even leverage AutoVue's powerful APIs to automate the addition of markups over certain text or pre-defined regions using our APIs. Black out the text you want to hide: CHECK! 3. With AutoVue's conversion capabilities, you can 'burn-in' the comments into a new file, either as a TIFF, JPEG or PDF document. Burning-in the redactions avoids slip-ups like the recent (well-publicized) TSA one. Through our tight integrations, the newly created copies can be directly checked into the content management system with no manual intervention. Make a copy of that document: CHECK! 4. Again, leveraging AutoVue's integrations, we can now define rules in the system based on a user's privileges. An 'authorized' user wishing to view the document from the repository will get exactly that - no redactions. An 'unauthorized' user, when requesting to view that same document, can get redirected to open the redacted copy of the same document. Release or distribute the new 'redacted' copy: CHECK! See this movie (WMV format, 2mins, 20secs, no audio) for a quick illustration of AutoVue's redaction capabilities. It shows how redactions can be added based on text searches, manual input or pre-defined templates/regions. Let us know what you think in the comments. And remember - this is all in our flagship AutoVue product - no additional software required!
