I have searched the whole group but wasn't able to find a answer for my problem.I want to record audio from the microphone, apply some audio signal processing and than save the processed audio data in a compressed format.I figured out, how to record audio uncompressed but now I wonder if I can use some api functions to store this data in a supported compressed format.

For example, can I plug a microphone into the 3.5mm jack and start recording the audio. (given the hardware is capable) Which leads me to my next question, if so, is there an app for it? I searched and searched but couldn't find much info on it...

How to record audio into ogg format?
View 1 Replies View RelatedI'm new in Android development and I have the next question/problem. I'm playing around with the Media Recorder class to record just audio from the microphone. I'm following the steps indicated in the official ://developer.android.com/reference/android/media/MediaRecorder.html
So I have a method that initializes and configure the Media Recorder object in order to start recording. Here you have the code:
//initializes audio recorder
//configure the input sources
mrecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
//set the output format
mrecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
//set the audio encoding
mrecorder.setAudioEncoder(MediaRecorder.AudioEncoder.DEFAULT)
My application cannot handle the JNIE overhead, as I need to make 2 JNIE calls to the native C/C++ code for every 20msec. So I am trying to use the native media libraries and the realted C/C++ files provided by Android in the folder "//external/srec/audio/test" of the donut build. Ex. AudioHardwareRecord, AudioInRecord etc.. I am implementing all the calls in the native layer.
I am using the sampling rate as 8000 and want to read 160 samples (320 bytes) at a time.
I used the following values to create the AudioRecord..
CODE:..........
It says "success" after creating this interface but I am getting the error "Bad Value" if I am doing the InitCheck.
And it is crashing once I start reading the samples or if I try to retrieve the configured sampling rate.
Has anybody tried to access this native code?
i'm big into freestyling. i have over 1500 instrumentals on my phone.i can't figure out how to play them and record myself (either audio or video) at the same time.i figure i'm either gonna have to download a new music player that won't close or a video/audio recorder that won't close the "Music" player that came with my evo.and before anyone goes tryin to be smart, i realize that even if i was able to accomplish such an action the quality would probably be really low due to speaker and mic being so close.my intent is more of a "on the fly lyric composition" rather than a " put myself on youtube to show everyone how awesome i am"

I would like to access the audio that my call manager captures while a call is active.
I would like to access it before it is transmitted to the other party.
I am trying to play a ringtone that is specified as the Default system ringtone. Unfortunately when i get the actual URI I get the above (content://drm/audio/2) and then when I try to play it, I hear the fallback ringtone - the one that you'd hear if the default was unavailable.
Ringtones appear to get this URI when downloaded through sites such as Myxer and the like.
Now it seems that when the default ringtone is on the SD card under a folder called 'ringtones' I do not run into this problem.
I have tried to add the line:
<uses-permission android:name="android.permission.ACCESS_DRM" />
...to the manifest but that doesn't seem to work either.
If anyone has an idea as how I would be able to play this ringtone, I would be eternally grateful! I have been researching this and I can't seem to find anywhere any documentation on how to do this.
Is it now possible mit sdk1.6 the audio decoder to access/use without using MediaPlayer ?
I saw : New version of OpenCore
Android 1.6 includes the updated OpenCore 2 media engine, which has:
* Support for OpenMAX encoders* Support for additional audio codecs in AuthorEngine* Improved buffering model supports shared buffers allocated in the decoder. but dont know how!
Can android apps share access to the audio output? I sometimes use Maps Navigation, which will give audible turn by turn instructions. I plug the EVO to my car stero using a patch cord so that I hear the instructions over my radio.
However, if I'm using another application that outputs audio, like Pandora or the music player, they go silent as soon as Maps speaks an instruction.
What I would like is for the apps to be able to share the audio output with some kind of priority set, so that Pandora would pause momentarily while Maps spoke an instruction and then resume.
Is that possible?
Is it only possible for one object to access the microphone at a time? That is, could I simultaneously use an AudioRecord to do some audio processing and use a MediaRecorder to record the incoming audio?
