Android :: Microphone Audio Capture With Emulator Is Of Very Poor Quality / Make It High?

Jun 2, 2009

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

Here is the Activity source: http://juzzam.org:9090/RecordMicrophone.java.txt

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).

Android :: Poor Audio Quality Captured From Microphone With MediaRecorder / Implement Them?

Aug 11, 2009

I'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.

Mar 24, 2010

I have the N1's dock connected to a pair of M-AUDIO AV-20 speakers and the sound quality is less than enjoyable. The question is, does the phone get connect to the dock through bluetooth? I would expect a much better audio quality from ANY Dock.

Motorola Droid X :: Poor Audio Quality While Charging?

Aug 23, 2010

I am trying to listen to pod casts on my DX while it is charging via USB. For the first 5 minutes or so it works great but then I start to get static. The static goes away as soon as I unplug the USB cable. Same thing happens in the car while listening to pod casts and plugged into my car charger.

HTC EVO 4G :: Poor Bluetooth Earpiece Audio Quality With Handset

Jun 24, 2010

How is Bluetooth audio quality with your Evo? I'm using a Jabra Extreme earpiece and am experiencing poor audio quality. One person with whom I was speaking said that I sounded like I was running or was in a windy location (I was calling from a quiet hotel room). On my end there was noticeable static. As a test, I hung up and paired the Jabra with my Blackberry 8830, and the person with whom I was speaking said that I sounded a little distant, but otherwise clear. On my end, the audio quality was good.

HTC EVO 4G :: HTC EVO Poor Picture And Poor Sound Quality

Jul 23, 2010

I use to own a palm pre before I switched to HTC EVO. I think the evo is a great phone but the two things I missed so much about my palm pre is the camera and the sound qualities.

The EVO is said to use 8MP for its camera but honestly the camera quality is nothing compare to the palm pre. Simply put, the camera and the sound output on the evo sucks.

You can clearly notice the difference between the pictures I took using the pre and the evo. The pre gives far better picture quality and also better sound output. I always enjoy plays my sounds or using pandora on my pre, but with the evo the different is the case. The sound quality with the evo is horrible even when plugged to good speakers.

I bearly take picture with the evo because I am used to good picture quality with my pre.

I have had the evo for less than two weeks and i am seriously thinking of returning it because of these two issues.

I really want to know, is this poor picture and poor sound qualities a thing with the evo in general or is it just with the particular evo that I got.

HTC Incredible :: Poor Incredible Sound Quality - Poor Verizon Customer Service

May 26, 2010

I (like hundreds of others) have had a call quality problem with the two Droid Incredibles I purchased for my wife and myself when they were released on April 30th. Verizon recognized that there was a problem and replaced both devices with ones manufactured about a month later (5/02) and the same issue with poor voice quality continued.

We love the device EXCEPT for the lack of ability to understand callers. So, I asked Verizon to extend our 30-day opt out to give them an opportunity to work out the issues with this device. I just received a call from Verizon customer service (which I could barely understand) and was told they would not extend the 30 day period and my option was to live with the poor sound quality or switch to another device. Verizon has no other devices that were interested in at this time so well be canceling these two lines (and one other) and returning to T-Mobile. T-Mobile may not have the best coverage, but they do have great customer service, unlike Verizon.

Sprint HTC Hero :: Poor Battery Life Or High Awake Times

Jul 12, 2010

For those that suffer from poor battery life or high awake times, I was given a code to enter that will give you all kinds of hidden info about the battery and what programs are running in the background keeping the phone from sleeping. Hit phone, as if you were dialing a number to call, enter *#*#4636#*#*, then talk. You will seee a menu come up that you can change to show you all kinds of hidden info on the phone and battery. Hope this helps some of you that are suffering poor battery performance and high awake times.

Android :: Can We Get Raw Audio Off Microphone Using Droid

Nov 23, 2009

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?

Android :: High Quality Youtube Playback

Mar 3, 2010

I moved from the iphone to the hero and so far things have been great. Now to my question. On my iphone I had jailbroke it and was able to get an app to fool the phone into thinking it was on wifi when using the network data. This resulted in high quality youtube playback like when in wifi at home. Is there an app or a way to get the same thing on the android OS? Been looking around and have yet to find something. On another note. I have two gmail accounts set up on my hero and only get the proper push with one of them. Is this common?

Android :: Nexus One And High Quality Youtube Video

Mar 8, 2010

From our android app I launch Youtube app with the proper video id. This works well across all devices. On Nexus One the youtube app defaults to using low quality video. I have added &fmt=18 in the url (for eg: http://www.youtube.com/watch?v=NsjadfLYnD4&feature=youtube_gdata&fmt=18 , see this blog for details http://blog.jimmyr.com/High_Quality_on_Youtube_11_2008.php) which should have forced a high quality video but doesn't.Anyone know a work around for this ? The screen resolution on nexus is really beautiful it saddens me that I can't make use of this to play hq videos.

Android :: High Quality Image Resizing / Scaling

Nov 17, 2010

I need to scale down images coming from a Network stream without losing quality. I am aware of this solution Android: Strange out of memory issue but it is too coarse - inSampleSize is an integer and does not allow finer control over the resulting dimensions. That is, I need to scale images to specific h/w dimensions (and keeping aspect ratio). I dont mind having a DIY bicubic/lancoz algorithm in my code but I cant find any examples that would work on Android as they all rely on Java2D (JavaSE). EDIT: Ive attached a quick source. The original is 720x402 HD screen capture. Please ignore the top 2 thumbnails. The top large image is resized automatically by android (as part of layout) to about 130x72. It is nice and crisp. The bottom image is resized with API and has severe artifacting. Code...

Android :: Voice Calls Uses Its Own Audio Instead Of Build In Microphone

Apr 22, 2009

we'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.

Nexus :: One VoIP Sound Quality Is Very Poor

Jan 6, 2010

I have both a Droid and a Nexus One. I have both of them set up for VoIP calls, and both are set up the same way. Here's how I set them up:

How To Set Up VoIP on the Nexus One Google Phone using Sipdroid for Free Calls | Dave's Tech Shop

How To Set Up VoIP on the Motorola Droid on Verizon Wireless using Sipdroid for Free Calls | Dave's Tech Shop

The call quality on the Nexus One is much worse than the Droid. I did repeated tests with both. And I used WiFi, so it can't be a difference between VZW and T-Mobile.

Anyone else tried VoIP on the Nexus One yet? I wonder if I have a defective phone or if this is a bigger issue.

The VoIP call quality problems are worse when using a headset on the Nexus One! VoIP quality on the Nexus One is marginal to poor without a headset, but with a headset it is unacceptable. I have tested four different headsets now. I have also tested those headsets on the Droid, and they are good. So the problem is the Nexus One, not any particular headset. My first thought was that I had a bad headset jack. However, after more trouble shooting I tend to think its not as simple as that. Music sounds fine through the headset. It is only VoIP sound that sucks when using a headset. The problem is so bad that phone calls using a headset are not workable.

Summary of Nexus One and VoIP:
* VoIP sound quality is marginal on WiFi with no headset.
* Music sound is good with headset on Nexus One.
* Headsets I'm testing with are good with VoIP and music on Droid.
* VoIP on Nexus One with a headset has poor sound quality.

Android :: Image Displayed At Webview From Url With High Quality Loss

Mar 17, 2010

I want to display an image from an url with an Webview at Android. With Android phones with Version 1.5 and 1.6 there is no problem. but the same pic and the same code on an AndroidPhone with Version 2.0 and the pic is totaly pixelated. Like Android is resizing the image first to a smaller one and then resizing it back to "normal" size. Unfortunately its important to display the pic without any quality loss. I tried to integrate it in the sourcefolder to show it as an normal image, but at Android 2.0 i get an exception because the image is to big. (At Android 1.6 there is no problem) Any ideas how i can display the image without quality loss with Android 2.0 ?
