View 1 Replies View RelatedIs there a way to determine the audio format of an audio file in Android? On normal java I do it like this:
File file= new File(...);
AudioInputStream stream = AudioSystem.getAudioInputStream(file);
AudioFormat format= stream.getFormat();
Is 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?

View 5 Replies View RelatedI've recorded audio in my Android application in its AMR format and I'd like to convert these to something that I can more easily use, such as WAV or MP3.
I've found some online instructions for this, for instance: http://www.aquarionics.com/2004/08/04/how_to_convert_amr_files_to_mp3/
which say to start with the 3GPP reference solutions to convert AMR to WAV, and then use sox and lame from there.
I compiled this code and tried to convert my AMR file, but it seg faults. I think this is because Android's AMR files are wrapped in a 3GP container. There is some code online about how to unwrap the AMR files (http://www.benmccann.com/dev-blog/extracting-amr-audio-from-android-3gp-files/), but I can't seem to get it to work and it seems like a lot of extra trouble just to get the audio from these files.
I connected my phone via USB to my RR sport to upload audio files to the RR hard drive. However, I keep getting connection error. Apparently my device is not being recognized as a storage. I did the unmount thinking. Also, I am wondering how I can play audio from my phone through the RR audio system.
RR is 2010.
I have multiple audio files in the assets directory of my application. When the user clicks a button I want to play those files in a certain order, one after the other. There shouldn't be any noticeable lag between the audio files. What is the best approach to achieve this? I am thinking of using MediaPlayer objects and OnCompletionListeners. But, that would mean I have to create a lot of OnCompletionListeners because I need to know every time which audio file is next. Am I missing something or is there a better approach?

View 7 Replies View RelatedI've created an application which uses around 15 small audio files. Right now I'm using mp3 files and each is around 200KB. These files are stored in my res/raw directory. I'm using SoundPool class to play the files in my application. I'm hoping to put this application on the android market place. Can one of you suggest what is the best way to store so many audio files? Will my application be scalable? Is wav or ogg format better approach instead of mp3? Please let me know.
View 3 Replies View RelatedI think I should know this, but my mind has gone blank. I'm making an app that has a few hundred small sound files and I want it to play a certain file dependent on a String I pass to the function. Where I hit the brick wall is getting the resId of the sound file.

View 6 Replies View RelatedSome audio files return 0 from MediaPlayer.getDuration(), even though they're perfectly valid files that play ok and that players on Windows can find the duration of. There seem to be two different cases here: certain file types such as .wma and .wav always return 0 duration, and others only do so sometimes. I haven't been able to find any pattern in the latter case, but it does seem consistent per file. The music player displays 0:00 duration for these, so it's not just my code.

I have a audio files in a particular directory. I want to list the those audio files in a listView.
please tell me how to do this activity.
I've been trying to understand how to get data about all the audio files in the device using MediaAudio but unfortunately the documentation is far from clear. Also, thereīs almost nothing about it on the forum right now and I couldnīt find good resources over the internet.
Iīve seen pretty quick and objective examples on how to access the main information from the containers but I couldnīt find in any place how I could get the names of the tracks (MediaStore.Audio.AudioColumns doesnīt have an specific constant for it) and the most important, how I could retrieve the path for the media (audio file in this case) Iīve found using the info on MusicStore.Audio.
am I missing something here? It seems it should be so easy but I canīt find the info! Also if I change any data on the container, will this data be also changed in the real file as well?

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 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 have a button that plays an audio file on its click listener. If the button is clicked again and again while the audio file is being played then the app crashes. What's the solution?
