audiorecord

I'm trying to use the AudioRecord class to record a WAV file. The problem is that it only supplies the raw PCM data, and if I write it to a file, there is no header information, so it will not play in any media player. How can I create a WAV file from this raw data? Or alternatively, is there any other way to record sound in Android to a WAV file (or, alternatively MP3)? Oh, and I know that MediaRecorder can'y be used because it doesn't support either WAV or MP3 formats. OK, I've got this figured out.

I'm using AudioRecord to record 16 bit PCM data in android. After recording the data and saving it to a file, I read it back to save it as .wav file. The problem is that the WAV files are recognized by media players but play nothing but pure noise. My best guess at the moment is that my wav file headers are incorrect but I have been unable to see what exactly the problem is. (I think this because I can play the raw PCM data that I recorded in Audacity) Here's my code for reading the raw PCM file and saving it as a .wav: private void properWAV(File fileToConvert, float newRecordingID){ try {

I'm trying to implement AudioRecord (MIC) -> PCM -> AAC Encoder AAC -> PCM Decode -> AudioTrack?? (SPEAKER) with MediaCodec on Android 4.1+ (API16). Firstly, I successfully (but not sure correctly optimized) implemented PCM -> AAC Encoder by MediaCodec as intended as below private boolean setEncoder(int rate) { encoder = MediaCodec.createEncoderByType("audio/mp4a-latm"); MediaFormat format = new MediaFormat(); format.setString(MediaFormat.KEY_MIME, "audio/mp4a-latm"); format.setInteger(MediaFormat.KEY_CHANNEL_COUNT, 1); format.setInteger(MediaFormat.KEY_SAMPLE_RATE, 44100); format.setInteger

Is there a way to record mic input in android while it is being process for playback/preview in real time? I tried to use AudioRecord and AudioTrack to do this but the problem is that my device cannot play the recorded audio file. Actually, any android player application cannot play the recorded audio file. On the other hand, Using Media.Recorder to record generates a good recorded audio file that can be played by any player application. But the thing is that I cannot make a preview/palyback while recording the mic input in real time. Any feedback is very much appreciated! Thanks in advance!

I am designing an Android app and I need to implement an AudioRecord class to record the user's sound. After some research (that didn't provide enough information) and few failed attempts, I was wondering if anyone could help me by posting an example (code) on how to capture high quality sound using AudioRecord. I would really appreciate it. Thank you Rahul Baradia Here I am posting you the some code example which record good quality of sound using AudioRecord API . Note: If you use in emulator the sound quality will not much good because we are using sample rate 8k which only supports in
