CODE:..................
This may be impossible but is there any way that I can get a smaller buffer size for AudioTrack than what is provided by getMinBufferSize method?
This is how I am instantiating AudioTrack right now: SR = 44100; bufSize = AudioTrack.getMinBufferSize(SR, AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_16BIT); audioTrack = new AudioTrack(AudioManager.STREAM_MUSIC, SR, AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_16BIT, bufSize, AudioTrack.MODE_STREAM);
With sample rate of 44100, getMinBufferSize always returns 4800. If I try to make the buffer size smaller than 4800 then I get the following error message: E/AudioTrack( 318): Invalid buffer size: minFrameCount 1200, frameCount 600 E/AudioTrack-JNI( 318): Error initializing AudioTrack E/AudioTrack-Java( 318): [ android.media.AudioTrack ] Error code -20 when initializing AudioTrack.

I am trying to playback voice data which is received in form of RTP packets in my application. The class
Receiver.java extends thread is playing back the audio. The question is
1. For real time streaming operation how to configure the write(byte[], int offsetInBytes, int sizeInBytes) methods?
2. What is the function and purpose of getPlaybackHeadPosition() What is playback head position kindly explain! Note: The RTP packets I am receiving are not from a traditional Datagram Socket but rather then from Ad Hoc Network so there is unknow delay for receiving the RTP packets. I need to design the Receiver class to play back the voice as soon as packets are recieved.

I am creating an android app that basically records an applies an "Effect" on the audio track then plays it back. I got my app to record an play back but I am stuck an not sure where do go from here. I have been Googling for days now trying to find a open source audio library or some way to change the audio after I record it. I currently have it setup to play back using SoundPool an I't lets me speed up an slow down the audio. I would like to do things like change pitch an add echo etc. I will appreciate any responses because I am totally stumped right now.
View 1 Replies View RelatedI am using a MediaPlayer instance in order to stream audio files from an Internet location. The audio player is in a separate activity. The user can select from a list of audio files and come to this activity which plays the audio.Now the user might go back to the previous activity (with the list)and select another audio file. In this case, I want to stop any other audio that is playing and start playing the new audio which was selected.Is there any way I can know whether an audio file is playing without having to hold on to the MediaPlayer object?

View 2 Replies View RelatedI'm trying to very quickly port over an html application with plays sound (with soundmanager2) to a native android app using WebView. From my research, I haven't seen any evidence that sound, such as mp3s, can be played via javascript or any other methods using WebView.
My goal now is to quickly port over the html app and then eventually create a truely native application without using WebViews.
If anyone has been able to successfully implement playing audio using WebViews and Javascript or if this is just not possible at this time.
I want to accept incoming calls and play an audio file for the caller. Is there a possibility of playing an audio file during a phonecall, so that the caller hears a wav- file? It seems to me that nothing is possible during a phone call since release 1.0. Hope this is getting better in the next release.
View 5 Replies View RelatedMy self-teaching project is a small application which plays an audio news stream. To be effective, the application really needs to interrupt any currently playing media players (eg: Last FM, Imeem, music player, Spotify etc).I don't know what will be playing or what application will be playing it, but I want to ask them all to pause until I've done. Sounds rather bold, I know, but it must be possible, because when there's an incoming call, that's basically what happens.Can I send a message to all audio players asking them to pause for a moment? Could I spoof an incoming call, just for the time it takes?

View 2 Replies View RelatedI am trying to make a very simple radio player for Android and I cannot get the audio streaming to work. In my latest attempt it plays for about 1 second and stops for some streams and it doesnt work at all for some other streams. Logcat doesn't give much useful information to me. I am testing on HTC Hero (Android 1.5).
If I hook the completion and buffer events I see the audio gets a complete event but it keeps buffering. Is there anything wrong with the code below? Should I be able to stream the the audio streams below? Is there a complete example somewhere of a working radio streaming?................
Is it possible to play audio over an active phone call, so the other end can hear it?
For example: A and B are talking on the phone. A presses a button that pulls audio from a resource and plays it over the phone call to B.
If so, what libraries should I look into? If not, is this something that could become accessible on rooted phones? (Of course, only other rooted phones would be able to use the application then...)
I want to play an audio file on a voice call as following:
The application initiates a call from device X to device Y
When Y replies application on device X should inject an audio file in the stream of the call so device Y hears this audio file.
My music application constantly plays music in the background, however I'd like to be able to detect when another application starts playing audio (such as the YouTube app) so I can pause/mute/stop the audio in my application. This will allow a user to continue browsing the web whilst listening to music, but then if they wish to watch a video at any point, they can do so without audio conflict.
One solution might be to listen for a broadcast which states when an application begins using the AudioManager. Does such an Intent Action exist? Edit: As in the answer provided below, there appears to be a method of detecting the loss of audio focus in 2.2 with AudioManager.OnAudioFocusChangeListener.
I have a activity which is called from another activity as an intent... This activity loads and starts playing a audio file. All is good - that much works. The activity also has a "stop" button and that stops the audio from playing - that is also fine.
But how do I stop the file from playing if the user uses the back button to leave the activity without clicking on the "Stop" button?
I have a requirement where I need to play an audio file in receiver mode(earpiece).I am not sure whether higher versions of Android SDK supports this receiver mode.I went through some links which said about 1.5/1.6 having changes in these Audio APIs and hence not sure.
View 1 Replies View RelatedHey, I have a problem with android programing when I try to record and then play the file that was just recored. I can both record and play the sound but the quality stinks. Its not just bad is really hard to listen to and sound abit like its a computer generated voice. I use the andriod SDK-emulator. The code that sets up the recording looks like this;
MediaRecorder recorder = new MediaRecorder();
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setOutputFormat(MediaRecorder.OutputFormat.RAW_AMR);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setOutputFile(path);
recorder.prepare();
recorder.start();
And the code playing the file later looks like this;
MediaPlayer mp = new MediaPlayer(); mp.reset();
mp.setDataSource(path); mp.prepare(); mp.start();
I don't know what part that makes the audio file sound really bad or if its just the emulator that makes it bad and that it would work on a real phone.
I'm using the SoundPool to play a series of small audio clips and am having issues with the audio when it starts. I have the audio attached to a button press. When I press the button mulitple times the tick persists. I was wondering if this was the audio file itself or is there something I need to do differently with the SoundPool other than play simply play the clip. These are .ogg files I created using Audacity. When I play them in my dekstop media player, they sound fine.

View 1 Replies View RelatedIs there an Android equivalent to the iOS Core Audio / Audio File Stream Services? I need to be able to read audio bytes from a network and feed them to the audio system under my control, so I can do my own timeouts / reconnects / range requests / etc. without interrupting the audio playback (since the system audio thread would be playing audio already enqueued). It seems that MediaPlayer doesn't give me this level of control. Is there a lower-level framework that does, either in the SDK or NDK?
