hey there,
I've got an app that records audio. I'm wondering how I can increase the gain. is there a way to normalize the audio or amplify it somehow?
thanks,

We are developing a social website and looking to implement video/audio chat for users (people a user is friends with). Most of the talk from the tech team was to use flash. But I don't want users to install anything. Can video/audio/conferencing be done purely in AJAX? Either develop it from scratch or use open source frameworks if any?
Let's say that I have Microsoft Media Server stream (i.e. mms://[some ip address here]). This stream contains both audio and video. Is it possible to stream this to an Android phone? How would I go about doing this? Preferably with video, but if it is an audio stream only that would also be okay.
Hi! Using Pixel-Bender, it's possible to manipulate audio with effects, mixing channels etc. (http://www.kaourantin.net/2008/10/audio-mixing-with-pixel-bender.html). Could this technique somehow be applied to a video sound track?

I'd like to use Festival in an iPhone app. Is this possible, considering the way Festival generates and then plays back audio files? Can I pass Festival an audio file directly from itself to play back? or is there a different way to read things?
Is there another Text-to-speech engine for C/C++ to use with iphone?
I am running remote audio-file-fetching and audio file playback operations in a background thread using AsyncTask. A Cancellable progress bar is shown for the time the fetch operation runs.
I want to cancel/abort the AsyncTask run when the user cancels (decides against) the operation. What is the ideal way to handle such a case?
I am looking to use ogg vorbis, instead of mp3s to stream audio. It seems that Flash player does not natively support ogg. Is there a codec engine that can be embedded with the app itself that can play .ogg instead of .mp3?
In general, what would be a better format than mp3 for streamingaudio and that is supported by Flash?
Hi, I have an app that records and plays audio with AVFoundation. I'm trying to work out how I would implement an audio trimmer (kind of like the one in Quicktime for Mac) and am totally stumped. Can anyone offer any help on how I would do this? Thanks!

Hi,
Was just wondering how do these sites (and many other softwares that generate flash movies from audio clips,images , docs) work ? how do they compile the media files(audio/image/vid) into a flv movie on the server ? Can the same be done using some open source tech.
Any info or hint or some direction where i'd get more info regarding this would be very helpful.
Thanks
I'm working at the audio buffer level, mixing audio signals created by a colleciton of objects. Since I'm looping through these objects at 44.1khz, efficiency is crucial. Is there any difference in the efficiency of iterating over an NSArray vs a C array of pointers? How about NSMutableArray?
I have a uinavigationcontroller with 2 views. In the second view I have some audio playing. When I click the back navigation item on the navigation bar the audio still plays. How do I end the process of anything happening in the second view when the user clicks back to the initial view.
Thanks for your help.
I'm uploading some audio to soundcloud, but would like to add the audio to a specific playlist i have also created, without making an extra request (see "Adding Sounds to a Set" http://developers.soundcloud.com/docs/api/guide#uploading). Is it possible to upload directly to a playlist?
Alternatively, I could send an extra request to add the track to the playlist but how would you do this in AS3. I see examples for JavaScript but am unsure how this would work in Flash.
Hi,
I have one audio file captured from my iphone. I want to upload this audio file using SFTP protocol?
Is is possible? Is there any third party library available? Is it the same as putting file on FTP?
Thanks,

Hi! I wish to download a video from YouTube and then extract its audio. Can anyone point me to some C# code to download a video? Thanks!
UPDATE: For clarification purposes, I already know how to extract audio from a .FLV file like these. Thanks!
What approach is considered to be the best to store and manage video files? As databases are used for small textual data, are databases good enough to handle huge amounts of video/audio data? Are databases, the formidable solution?
Apart from size of hard disk space required for centrally managing video/audio/image content, what are the requirements of hosting such a server?
I have the table :
id id_products id_atribut name value
1 13 8 autdio 2.1
2 13 9 hdd 200 Gb
3 13 10 cd-rom 2
4 20 8 audio 2.1
the problem is, how can i select from this table where name="audio" and value="2.1" and name="hdd" and value="200 gb" and return id_products=13 ....
How can i do this?
I'm creating a view with images, videos, audio and documents (books) and I like to shown a picture of each of them in a carousel.
Everything works nicely with images and videos as far as we added a image-thumbnail (image filefield) to their CCK but we like to show a default image for audio and documents without changing the original CCK. Is it possible with imagecache (may be with imagecache_custom_code or views_custom_php) or we need to look for a different approach?
Thanks for your help,

Hello
I create my custom WM encoder profile. The reason I need a custom, non
standard WM profile is that I need that the video resolution must be
the same as input video stream. I created below profile but after I
encode my video and audio with it, the WMP while loading says that the
WMV1 codec is not found and prompts me for downloading WM encoder
codecs. After installing them, the problem still exists.

I am trying to do an app, to where when it launches, it will detect audio, and then play it back automatically. NO BUTTONS, NOthing to press. Just a picture of something then, it listens for audio, then plays it back. Similar to the Talking Carl app in the App Store. Any ideas/help? Would appreciate it, if i could use the code with IB.
