This might be a round about way of doing it, but are there any time-stamped audio formats out there? Also, how is video-audio synchronization usually done?
Thanks in advance.
Good day everyone and happy holidays.
I'm trying to create a "simple" program that allows me to create a list of video files (Youtube video's to be precise) that are then run through by my program and converted any given format to pure MP3 audio. For this purpose I'm trying to use the BASS.dll and well it isn't going so well.
I was wondering if…
So I want to stream the audio from a mic using NAudio and then pass that stream to WCF which a Siverlight app can consume to broadcast the live audio sound. I want the latency to be as low as possible.
Any suggestions or if some one has already done it please point the source. Thanks in advance
Is there a mature library that could enable audio input and output and work within Haskell? (A nice wrapper is fine, of course.)
I'm looking for something that can easily capture microphone input and, perhaps, play various audio files as well.
Thanks.
I've noticed certain radio apps, that some stations required wifi and others did not. What were those other stations possibly using? Are there other methods of streaming audio on iOS?
Apparently, I was not clear in my question before.
I'm asking in terms of API's. Is there an API to interact directly with say, FM radio, on iOS? Is wifi the…
Hi,
it seems that this question has been asked before, I just would like to know whether there is an update in Android.
I plan to write an audio application involving low delay audio I/O (appr. < 10 ms). It seems not to be possible based on the methods proposed by the SDK, hence is there - in the meantime - a way to achieve this goal…
I cant seem to play any audio with CMUS because it always gives the above error

I was able to play such a disc using VLC, but I am wondering if any music player supports the DVD-A format.
UPDATE:
I checked Rhythmbox and Banshee - I found no option like Play Disc or Open Disc, so I have no idea how I could even try to start playing a DVD-A disc.
This has also nothing to do with missing plug-ins or codecs - the…
I'm having a problem with pulseaudio. My machine crashed, and when I rebooted and ran pavucontrol, I got a "Connection Failed: Connection refused" dialog.
When I run pulseaudio --log-level=info --log-target=stderr from the command line, I get the following output:

Hello,
I am trying to understand conceptually the best way to deliver real streaming audio and video content. I would want it to be consumed with a web browser, utilizing the least amount of proprietary technology. I wouldn't be serving static files and using progressive download, this would be real audio streams being captured…
From ASP.Net, I am using FFMPEG to convert flv files on a Flash Media Server to wavs that I need to mix into a single MP3 file. I originally attempted this entirely with FFMPEG but eventually gave up on the mixing step because I don't believe it it possible to combine audio only tracks into a single result file. I would love…
Hi,
I'm designing a cross platform (Windows/Linux/OS X) application, something like a digital audio workstation. I'd like to create a software where users have a fully featured sequencer (multiple tracks with automation) and where it is possible to create instruments using a visual language (as Pure Data/Max MSP).
Ehm... I…
I'm using the Windows API to get audio input. I've followed all the steps on MSDN and managed to record audio to a WAV file. No problem. I'm using multiple buffers and all that. I'd like to do more with the buffers than simply write to a file, so now I've got a callback set up. It works great and I'm getting the data,…
I'm writing a UDP local area network video chat system and have got the video and audio streams working. However I'm experiencing a little latency (about half a second) in the audio and was wondering what codecs would provide the least latency. I'm using NAudio (http://naudio.codeplex.com/) which provides me access to the…
Foobar2000 is a great audio player that is fully customizable, is light on system resources, and contains a lot of tools and features. Today we show you how to use it to rip an audio CD to FLAC format.
Note: For this tutorial we’re going to assume this is the first time you’re ripping a disc with Foobar2000. We’re running…
I have a PIC18F4455 microcontroller which I am trying to use to send 200 values over USB. Basically I am using a for loop and a printf statement to print the values to the usb output stream. However, when the code executes I see in my serial port monitor that it is only sending the first 25 or so values, then stopping. …

If I run the 12.x ubuntu (latest May 2012) from the CD, I get full audio settings, and sound playing in speaker. Profiles let me change analog to digital in/out.
Once I run install from the same CD onto the laptop HD, once it boots the first time, after selecting audio settings, there is no 'Hardware' tab and no way…
My powertop reports this for the two audio codec components.
4.85 W 100.0% Device Audio codec hwC0D3: Intel
4.85 W 100.0% Device Audio codec hwC0D0: Realtek
I think 10 W for audio is too high. Can somebody please suggest me a way to reduce the power…
After the 12.04 Update my HDMI audio stops working anytime I turn off my 2nd monitor(plasma TV). Graphics card is a Radeon 6800 which has DVI out to 1st monitor, HDMI out to receiver which the TV gets it's Audio/Video. Audio is always via my receiver sound.
Things work fine as long as it boots with the TV and…
I'm using Ubuntu 14.04 and everything was perfect until todays's update. Now my audio output (speakers) and input (microphone) stopped working. I guess it's a driver issue, but I need help to debug this problem and to solve it. I have a Dell Inspiron 5421 notebook with an Intel audio integrated sound card:

I'm working on a couple different iphone apps that both record and play sounds concurrently. Think multitrack mixing... play one sound a save it then listen to that sound while recording the next sound to another file. My mechanism for this has been to start up two different audio queues, one for recording,…
Hi all,
Can other Safari users please test http://recaptcha.net/learnmore.html for me, to see if the audio reCaptcha plays properly? On my machine, I can only hear the audio if I click the Download sound as MP3 link. I also don't get the spoken introduction at all. It works OK in Firefox and Chrome.

What is the best way to convert various audio formats to PCM?
For example: mp3, evrc, ogg vox.
Is there a library out there that will allow me to implement this relatively easily?
EDIT:
I guess my initial question wasn't really what I needed. Most of the libs I have found are file converters. What I…
