A small program that I wrote cannot record the microphone. One api call, getminbuffersize keeps returning -2 which is not correct. The program works on a real android one. I use 11025Hz, 16bit pcm,mono recording.

As a first step toward a speech recognition project, we wrote a simple voice recording application based on the information in this thread: http://groups.google.com/group/android-developers/browse_thread/threa...
It is working; however, the audio is extremely poor -- too staticy for our needs code...
As a comparison, here is a similar audio file captured with audacity on a PC: http://juzzam.org:9090/myAudioFile_onPC.mp3
Has anyone been able to record high quality audio with the emulator? If not, is it any better on the android dev phone?
According to the documentation of MediaRecorder, there is only one audio encoder "AMR (Narrowband) audio codec" and three output formats--3gpp, mpeg, and raw AMR: http://developer.android.com/reference/android/media/MediaRecorder.html
Here is the Activity source: http://juzzam.org:9090/RecordMicrophone.java.txt
We are testing on Windows XP, with a Logitec USB microphone, eclipse ganymede, and we are using all the defaults for an android 1.5 app (no emulator command-line options.. we defined the sdcard in the avd manager).
I am trying to develeop a video capture application on the HTC Ion device using the MediaRecorder class. The application seems to run and record MP4 output file, but it is blank when I view it with QuickTime! I am wondering if I am setting up the MediaRecorder correctly. Also, expected to see a live preview because a Surface to display the preview was set . But nothing shows up. Any one have suggestions as to what could be doing wrong?
View 2 Replies View RelatedI have an application that I developed using the Android 1.1 SDK that I am trying to port to Android 1.5. In my application, I record a sound through the microphone and then do various things with it, including playing it back using a MediaPlayer object. My code works fine when I use the 1.1 target, but when I use a 1.5 target I get this error when setting up the player:
Command PLAYER_SET_DATA_SOURCE completed with an error or info PVMFErrNotSupported error (1, -4) Couldn't setup MediaPlayer java.io.IOException: Prepare failed.: status=0x1 at android.media.MediaPlayer.prepare(Native Method) at org.byu.chum.AudioUtils.AudioRecording.stopRecording (AudioRecording.java:92) at org.byu.chum.SoundRecorder.Recorder$StopListener.onClick (Recorder.java:198)...
It seems like Android isn't liking the format of my media, but I don't know why, since I just recorded that very format on the Android device. Here's the code that is throwing the error:
player = new MediaPlayer();
try { player.setDataSource(recordFile.toString());
player.prepare(); } catch (IOException e) { Log.e("playRecording", "Couldn't setup MediaPlayer", e); }
I've used the voice recognition feature on Android and I love it. It's one of my customers' most praised features. However, the format is somewhat restrictive. You have to call the recognizer intent, have it send the recording for transcription to google, and wait for the text back. Some of my ideas would require recording the audio within my app and then sending the clip to google for transcription. Is there any way I can send an audio clip to be processed with speech to text?

View 1 Replies View RelatedI have created an basic sound recorder application using MediaRecorder class. It has 3 buttons i.e.
1.Record: Start recording
2.Stop: Stop recording
3.Play: Play recorded file ( 3gp format)
I can record any number of files using this. Each files gets name as audio1,audio2 ..etc.The problem is after recording the file I can play it using play button. But if I exit my application I am not able to see that file listed in music menu in emulator. But at the same time when i browse my sdcard using eclipse I can see the recorded audio file. ( I have aleady mounted sdcard image and can see other sdcard content in emulator)Now if I close the emulator and relaunch it I can see that file in emulator music menu. Now suppose that file name is audio1.3gp. If I record a sound using my app it will record it using name audio1.3gp on same location. This time if I goto music menu I can see audio1.3gp file with latest recorded audio.
I have an HTC Evo 4G How do you send a recorded video in mms/text? I tried several times, but only when i record for 5 seconds(stupid) can a video be sent. Anything larger I keep getting file limit size is reached. Im sure that there is way for this to be done.

View 2 Replies View RelatedA few nights ago I brought up the camcorder to record some video, everything recorded very smoothly after it was done I went to the gallery to check out my video but upon play back the video was very hic uppy. And maybe I thought it was just that portion but it wasnt the whole video plus all my videos play hic uppy now. Anyone else having the same problem? Is this issue happening because of the froyo update.

View 11 Replies View RelatedI want to get the input/opinions of some other people on this topic. I have a couple of big events coming up that I will be recording with my (soon to have) Evo. Now I know that Qik is gonna be huge when it comes to 2 way video calls, but my question/dilemma is to either use the native Camcorder/Video Camera app and upload them to Youtube, or to use the Qik app and have it stored on the Qik site. From what I've heard and seen, when a video is recorded/streamed to Qik, the quality that results on the Qik site is NOT nearly as good as what you're actually seeing and recording on your screen (compression, whatever, bla bla bla). However, I have seen videos on Youtube from people with EVO's where the quality is a ton better and it looks really good. So, why would anyone want to use the Qik app to take video recordings, when the end result on their website is of less quality as supposed to using the Camcorder/Video Camera app and posting it to Youtube? Is the only benefit for Qik is that people can watch your video being streamed pretty much right then and there (with only a little delay)?

View 5 Replies View RelatedI've read a lot of posts in this group regarding raw audio processing. Most of them include references by Mr. Sparks about support for this in "future releases". I hope maybe he was referring to Android 2.0? To be clear, all I want to do is obtain audio data from the microphone in as high a fidelity as possible to perform DSP against it. This is blissfully outside the realm of any DRM-laden audio output issues (I hope).
So, in short, can we get raw audio off the microphone using Android 2.0 and a Droid, for example?
I have a bluetooth headset that works fine with android 1.5 for listening music or calling people.My problem is that microphone is only active when I call someone, but I would like it to be activated anytime, for dictation.Is there any way to activate bluetooth microphone with sdk or is there some special headsets that would be ok for that?

Does anyone know how to do this?

I'm not on the 2.2 update yet, but some videos I've recorded don't have a thumbnail in the gallery, nor do they play back.

Neither would play the sound. Anyone have a problem like this?
View 4 Replies View RelatedI would like to detect if microphone in the device or in a headset is mute during a call. Currently I've taken the following approach (unfortunately - it does not work): 1) register PhoneStateListener to detect when a call is started/ finished 2) when call is started then I start a thread that periodically calls audioManager.isMicrophoneMute() method to discover a microphone status. (audioManager is obtained by calling getSystemService (AUDIO_SERVICE) ) 3) when call is finished I stop a thread started in bullet 2
Unfortunately audioManager.isMicrophoneMute() always returns 'true', does not matter if I select or deselect the 'Mute' option in the menu during a call. Does anybody know if it is possible to detect the state of a microphone during a call?
