I am looking to create an application that will allow me to record from my mic and playback the recording through other pc's. At this point however I would just like it to play back on my own computer so I can get it working. I have been looking at NAudio for the past few hours and it seems like it may be able to help me achieve this g...
Hi! I was using audiotrack to play some sounds in a loop. Now I need to know in which period of time I'm right now, so i decided to use setPositionNotificationPeriod which works quite good. The problem is that it just work for the first "loop" but stop being called after that :\ The code looks like the following: ... audioTrack.setPos...
Hi everyone In the last few days I was trying to write small program to monitor the audio line-in using win-api (winmm.dll). I can pinvoke api functions such as waveInOpen but I can't figure out how to use these functions to achieve my target. the question is - can someone can briefly tell me how can I get the data from the audio line ...
I've got an application which records audio from the microphone and then performs some post-processing on the audio in realtime, so I must use the AudioRecord class instead of the standard MediaRecorder. My code for recording is as such: DataOutputStream dataOutputStreamInstance = new DataOutputStream(bufferedStreamInstance); android.o...
Hello, I got a flex3 app and a red5 0.63 server. My app plays audio only flv files stored in the server, but don't play correctly. It plays some milliseconds, and stops. It receives the metadata, the seekbar length is correct. When I try to seek, it goes back to the beginning and plays the same few milliseconds. do you have any idea? ...
I'm playing an audio clip using a UIButton that calls a method (see code below). I'm trying to figure out how to write a statement to detect if the audio is running, and if the audio file is playing then disable/hide the UIButton. At the moment if you keep touching the play button multiple instances of the audio clip play. -(void) aud...
My aim is to have a set of frequencies like 2 frequencies that represent the bits (0 and 1). I want to send those frequencies to the audio out through sound card. At the other end I connect the cord to mike in of the sound card. I like to sense that signal (generated series of 2 fixed frequencies) from other computer and re-form the data...

OSStatus recordingCallback(void *inRefCon, AudioUnitRenderActionFlags *ioActionFlags, const AudioTimeStamp *inTimeStamp, UInt32 inBusNumber, UInt32 inNumberFrames, AudioBufferList *ioData) { SInt16 noi= SInt16(inTimeStamp->mSampleTime); printf("\n%d", noi); noi= SInt16(inTimeStamp->mRateScalar); ...
I have no experience with audio programming at all and have been looking at the AV Foundation Framework thinking this is what I need to use to create an app that allows me to record and do simple editing of a recording. By simple, I mean have the ability to go to a part of my recording and snip out a segment. I've gathered that I shoul...
I have two audio queues that I want to synchronize to start playing at the same time. I would like to use OSStatus playbackCallback(void *inRefCon, AudioUnitRenderActionFlags *ioActionFlags, const AudioTimeStamp *inTimeStamp, UInt32 inBusNumber, ...
Hi, I want to record a sample from the microphone, then I want to play the recorded file maximizing the volume and apply some audio effect, like modifing sample rate or addind an echo. Waht is the best way? is there an example? ...
I want to measure a system's speaker volume by playing a sound and listening for it on a local microphone at the same time. This is for a specific application. The exact recorded sound is not as important as differentiating between the microphone volume recorded before the sound is played and while it is playing. The idea is to warn the...
I am looking to record voice in as compact a file format as possible for an ipad app, and not concerned about sound quality. I chose the ima4 format but don't really know much about audio, so am having trouble figuring out how to play back the produced file to test how it sounds. Is this a compressed format that I have to uncompress wi...
I wish to record audio at 32 kHz on my Symbian device but it only supports 48 kHz. From searching the internet I believe the term for what I am trying to do is called downsizing. Is there a C++ library that will compile and run on Nokia Symbian phones that will do this for me? Or is the algorithm simple enough for me to implement on my o...
I need a audio and videoplayer that is usable both in non flash-browsers (such as iphone-safari) and in non html5-video-enabled browser (such as all old browsers) Apart from this clean asthetics(think vimeo), support for many codec-types and easyness to implement are all bonuses. Free or paid doesn't matter! ...
Any suggestions? ...
I was hoping to make an application that did real time voice manipulation like the the T-Pain App. But AVAudioRecorder only enables a post processing from of audio manipulation. Is there another API that will enable real-time audio processing? thanks! ...
Hi experts :) I'm about to make a decision about the ideal technology for audio/video chat and I need your expert advice, specifically on the client side. java media framework doesn't seem mature enough, fms seems ok but are there any java clients for flash media server or Red5? any clues, guides appreciated. thanks ...
Hey, I was looking for a good MP3 or OGG decoder that use the BSD license or public domain and that is also light-weight (something that comes with sources without the need of platform specific configuration). ...
