I will describe briefly my trouble with audio recording.
So, I am doing audio recording using MediaRecorder, but unfortunately when I playback the recorded audio, I have media with a very low volume. I don't here anything (almost anything).
Is there any possibility to setup recording volume?

I'm writing an Android application that plays back voice mails using Media Player, which are just WAV files that have been sent to the device. When I play the file, it's played on the device's speaker, or else it plays through headphones if they're plugged in. What I want to do is play the file so that it sounds to the user as if it's at the same volume level as a normal phone call. Is there a way to route playback so that the file is played through the phone's ear piece instead of out of the speaker?

View 4 Replies View RelatedI'd like to create an audio recording in Android. (Actually, I just want access to the mic without recording it, but it seems that's not supported so I'll have to create a recording and tail the file). I'm having a very hard time getting started. Mostly I'm just hoping that someone from Google reads this and will update the documentation because the example won't compile - it looks like it's from some previous version of the SDK because there's an error in every other line. I made my best guess as to what the usage should be, but I keep getting a number of different exceptions. One question I had is whether I can just specify an arbitrary path to the MediaRecorder to start recording or whether I have to create an entry in the content database. The JavaDoc for MediaRecorder.setOutputFile isn't clear on what it's expecting.

However, my HTC Desire, even at the lowest possible volume, is still too loud for my fragile ears. Is there any way to fix this and change volume settings?

I have a Java application where in I am trying to read Audio samples from the mic into a buffer and then write the samples back to speaker from a buffer for playing. I have used AudioRecord and AudioTrack interfaces. Below are my configurations for the Record and Track object creation. AudioTrack(0, 8000, 2, 2, playBufSize, 1); AudioRecord(1, 8000, 2, 2, recBufSize); Using AudioRecord interface I am able to read the samples from mic continiously (8000 sampling rate and 640 samples per read). In the similar way I am also able to write some pcm samples to the speaker from a buffer and play it continuously using the AudioTrack interface (without record). But when I try to do both record and play simultaneously I am able to only record audio from mic but I am not able to play any samples to speaker. I am getting this error " ------- attemp playback while recording, cheat it! ----- " in the log cat.
I have given the following permissions "android.permission.RECORD_AUDIO" and "android.permission.MODIFY_AUDIO_SETTINGS" in the Manifest file. I didn't find any special permission to play the audio. Is there anything else that I need to enable?
I am developing a recorder application It works fine with Microphone. I want to record from Bluetooth headset. I set it like
my_Aud_Mgr.setMicrophoneMute(true);
//AudioManager my_Aud_Mgr;
my_Aud_Mgr.setBluetoothScoOn(true);
But it cant record from Bluetooth device. How to record from Bluetooth device.
Im trying to record audio directly from the system. Using the standard API, you can only record from the MIC or phonecalls, ala: MediaRecorder.Some ways I've tried is to read from /dev/audio and /dev/eac from my app, but I think the sandbox of the app is preventing this.Im thinking about using the NDK, but Im not sure if that would overcome the sandbox aspect ? Ideally, there is some solution outthere to access the audio sub- system directly. Whether it be directly to alsa, to the AudioFlinger, to /dev/eac

I tried screencast recorder, z screen recorder etc(to record video+audio then extract audio), but they all record audio from the microphone, so that didn't work out. is there a way to extract the audio from the game somehow, or some on screen audio recorder for android devices?
I've noticed times when my in-call volume is stuck on high even when turned all the way down to the lowest setting. I traced this to having previously connected to a bluetooth device for phone use (this happens with two different bluetooth accessories). After disconnecting from bluetooth (whether or not the bluetooth antenna is also turned off), call volume is extremely loud and doesn't respond to the volume-down key. I have to reset the phone to get it back to normal. Anyone else notice this? Any fix for this? I presume this is a bug in the Android 2.1 OS. BTW--this also happens with a friend's Eris running a 2.1 leak v3.

No ringers, no audio in videos, no touch tones, nothing. All the ringers are turned up, it's NOT on silent mode.
I can however talk on the phone, the ear piece works. Mic works too.

I love my Evo 4g but I have to say it lacks in sound quality. Phone calls get distorted if the volume is set too high. It sounds bad like the speaker is blown, I wonder if this is an actual defect or if it can be fixed with a software update. I also use Pandora and mp3 player and when I use my 3.5 mm to cassette adapter in my car the low/mid range frequencies are hollow sounding. I use many other devices in my car (ipod,laptop,Samsung mp3 etc.) And none sound like this. I've also plugged directly into home surround system and bose inner ear head phones and noticed this. I hope they can fix this with a OTA update .....

View 2 Replies View RelatedHey, I have a problem with android programing when I try to record and then play the file that was just recored. I can both record and play the sound but the quality stinks. Its not just bad is really hard to listen to and sound abit like its a computer generated voice. I use the andriod SDK-emulator. The code that sets up the recording looks like this;
MediaRecorder recorder = new MediaRecorder();
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setOutputFormat(MediaRecorder.OutputFormat.RAW_AMR);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setOutputFile(path);
recorder.prepare();
recorder.start();
And the code playing the file later looks like this;
MediaPlayer mp = new MediaPlayer(); mp.reset();
mp.setDataSource(path); mp.prepare(); mp.start();
I don't know what part that makes the audio file sound really bad or if its just the emulator that makes it bad and that it would work on a real phone.
I am trying to develop an app which streams live audio/video. I have the mediarecorder to record both audio, video frames , and it does so. But the thing is it records a chunk of audio and then records a chunk of video frames and then records a chunk of audio frames to the file. How do I determine where my audio frames start and where the video frames start?. Also is there any way to figure out the Video frame length ?. Iam really stuck at this point and any help will be greatly appreciated. This is how I initialize the mediarecorder in my app, Code...

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).
Voice recorder and all other 3rd party apps record audio like absolute garbage. I am very disappointed. Such an awesome camera and camcorder but it sounds like I am speaking through a damn kazoo. I am dying to know if it's firmware or just cheap hardware, not to sound bitter but the iphone has a SUPER high quality mic being that Incredible just came out I was very surprised at the low quality of the audio recording
