mediarecorder

I'm using the Android MediaRecorder to record AAC encoded audio files. Setting the output format to MPEG-4 worked pretty well. But as my audio player supports neither MPEG-4 nor 3GP I tried to get raw AAC files by using the output format AAC_ADTS , which is supported by Android since API level 16. mRecorder = new MediaRecorder(); mRecorder.setAudioSource(MediaRecorder.AudioSource.MIC); mRecorder.setOutputFormat(MediaRecorder.OutputFormat.AAC_ADTS); mRecorder.setOutputFile(mFileName); mRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AAC); Here is where I got stuck. The MediaRecorder created

My app records an audio clip and send the clip to the server using Retrofit2 after the recording is completed.The file is received in server,but the file is broken,what I mean by broken is that it cannot be played. I use the following URL(example url: mydomain.co/audio/myaudio.mp4 ) to play the audio clip,which I tried with another audio file using postman ,the audio file can be played successfully.Besides,even downloading the audio clip captured by android via Filezilla also has the same broken file. This is how I record the audio: private void startRecordingAudio() { Log.d("audiorecording",

I'm developing an audio processing application where I need to record audio, and then process it to obtain features of that recording. However, I want the audio in a playable format to play it after with MediaPlayer. I've seen that to record audio to process it it's better to use AudioRecord, because I can get the raw audio from there. But then I can't write the data to a file in a playable format (is there any library to do this in android?). I used this method to record raw data and then write it into a file: http://andrewbrobinson.com/2011/11/27/capturing-raw-audio-data-in-android/ But when

According to Android SDK MediaRecorder.setCamera can be used to recycle the existing camera instance for video capture and preview without resetting the preview. I was not able to find any sample, and all my attempts were futile: I either get the wrong state exception, or MediaRecorder.prepare fails. Does anyone know if this method usable at all? How can I use it then? Any samples available on the Web? For reference: http://developer.android.com/reference/android/media/MediaRecorder.html#setCamera(android.hardware.Camera) lyron I ran into the same problem and found out how it can work. Some

android手机的Mic对声音的感知 以下是转载的文章，前段时间我也在做mic录音方面的东东，等整理出来再总结一下。。 这段时间做了个有关android手机利用mic捕获外界环境音量的小东东，多方查询，各种研究，现在把这些东西跟童鞋们分享一下，如有不足或者差错，还望大牛们多给意见。 android提供可以实现录音功能的有AudioRecord和MediaRecorder，其中AudioRecord是读取Mic的音频流，可以边录音边分析流的数据；而MediaRecorder则能够直接把Mic的数据存到文件，并且能够进行编码(如AMR,MP3等)。 首先，要将你的应用加入权限（无论你是使用AudioRecord还是MediaRecorder）: <uses-permission android:name="android.permission.RECORD_AUDIO" /> 然后，分开介绍两者的用法。 《！--AudioRecord--》 1、新建录音采样类，实现接口： public class MicSensor implements AudioRecord.OnRecordPositionUpdateListener 2、关于AudioRecord的初始化： public AudioRecord (int audioSource, int sampleRateInHz, int

In short, I'm looking for a way to get the byte stream from the camera while recording video. The aim is to continuously record while saving certain portions of the current recording without stopping the actual recording process to access the output file. Is this even possible, or will I need to actually stop the recording and save it for it be playable? I've seen projects and open source library's that allow live streaming from the camera to a server via a local socket and the ParcelFileDescriptor class, so I assume (maybe incorrectly) that the recorder byte stream must be accessible somehow.
