Is there anyway in android to loop a recorded audio through microphone. I mean that instead of speaking in microphone, i should be able to send a recorded audio from code into it.

I'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?
How can I get the volume of the audio stream coming in through the android microphone?

View 4 Replies View Relatedwe're a group of students and trying to implement some kind of voice cryptography over a gsm connection (without modifing any gsm related codecs, we render pure audio which gets transmitted via gsm). Is it possible to initiate a voice call and transmit our generated audio signal (means bypassing the microphone as the primary audio source for that call)? I write this because I'm slightly worried after reading some posts on this list/group which states that the android.telphony APIs are private and can't be called from processes outside the the telephone subsystem.

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...

View 1 Replies View RelatedI've implemented "Audio Capture Setup and Start" example (http:// developer.android.com/guide/topics/media/index.html) with small modification - the output format is MPEG_4 not THREE_GPP.
The result - records with extremely poor audio quality.
Could you help me to understand where is error and how is possible to do really good audio records with Android?
I've done an experiment with Camcorder - standard Android application. Sound quality of the video is same poor. The audio signal is extremely low (quite).
Is it "by design" or may be some hardware problem (T-Mobile G1)?
I've found description similar problem here - http://osdir.com/ml/AndroidDevelopers/2009-06/msg00752.html - "Microphone audio capture with emulator is of very poor quality". In my case this problem reproduces on the real device. Unfortunately I have not found answer. I read about some "custom" encoders.. but have not found any example how implement them.
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

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 have a Galaxy Note 2 and can't figure out how to record via my bluetooth headset not via the phone mic. Tried 20+ apps that record great via the phone mic but not via my headset.
View 10 Replies View RelatedI have been searching for quite some time now, and I haven't been able to find a way to actually get an SPL/db value from a microphone on android. The few threads and articles that I have found that discussed it treated it like something SO obvious that anyone should be able to do it, and were more concerned with getting their conversion algorithms correct. Does anyone know how to do this?

View 2 Replies View Relatedjust started using the Pandora music app, but my kids in the back seat could not hear it. so I stopped by Walgreens and picked up the "JUPITOR JACK". you can't miss it cause it has the big red ad: "AS SEEN ON TV". it works well enough, but I had to tweak my car audio system to make it decent. whatever the droid plays comes out on the car radio, it's better then my old belkin FM transmitter.

I'm having trouble with my microphones and was wondering if anyone else had the same issues? Pretty much no one can hear me if I call them, If I set it to speaker they can hear me fine (via top mic) but when I try to talk normally, still the same muted mic. I cant find any settings for this and I have tried rebooting the device. Anyone know what may be causing this or maybe I got a defective X?

View 1 Replies View RelatedIs 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?
