I can use AudioRecord to pull the audio data out. But the format is PCM, which is too huge to sent out through network. Does any one know how to change it to AMR ?

I need to load an audio resource and play it, but I also need to be able to modify some parameters (like the volume, or the playback rate) while the audio is being played. For example, I might want to play a 10 seconds audio stream, and change the volume only after 3 seconds. Is there a way to do it? I've been experimenting a little with AudioTrack without results.
View 5 Replies View RelatedI'm trying to figure out how to write an app that can decode audio morse code on the fly. I found this document which explains how to record audio from the microphone in Android. What I'd like to know is whether it's possible to access the raw input from the microphone or whether it has to be written/read to a file.
View 3 Replies View RelatedI first have to say that I'm biased, 'cus I like to write music apps (like music generation apps). However, this affects games as well. It's somewhat disappointing how OpenGL has made it into the NDK now but there isn't any NDK methods to get to sound to have faster access. Over the weekend I did some more testing and if you make a "drum" app, for example, and play the sound using either SoundPool or AudioTrack, you will get about a 100ms delay buffer, which is clearly audible (gap).
I made a test app where when you touch the screen, upon the DOWN event, it would play a short sound (like a drum sound). It clearly was not real time responsive or even close - you could hear the delay. I'd be interested to know if anyone who has made a game has any trouble with sounds? It seems like they aren't going to really trigger real time enough if you use SoundPool, for example. Am I completely wrong? Seems like your game is going to perform an action, play a sound, but the sound will have latency which I would think would throw off the game a bit..................
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.

Is there any way I can do a REAL TIME phone simulation on my PC. Its alike TV output from phone to projector (Galaxy S can do that) but I have other Android which have no TV output function from the phone, so I wonder if I connect the phone to PC and get the real time screen output (few second lagging is ok for me as well) to PC than I can project it out via projector during discussion, presentation.

View 1 Replies View RelatedI am currently trying to braodcast real time voice from Android using RTP to other Android phones connected over Wifi Ad-hoc network. I have few questions in this regard,
1. How to control and set the RTP on Android? 2. Which Codec are supported by Android for voice communication? and how to incorporate them?
We are able to record a voice from microphone and store it on SD card for a playback. The next step would be to link the outstream of real time voice with RTP also incorporating Codec
I was wondering why Android keeps lagging a bit. I mean, quadcore should be fast enough to stop that from happening right? So I started Googling.
I got this article: [URL] .....
Basically it says this: Android's UI rendering thread does not work in real-time (the priority is not set at that), unlike iOS'. It's just about the one thing that's still better about iOS in my opinion.

View 2 Replies View RelatedI know you can apply Permissions for Applications on it's manifest.xml file. What I want to know is, can those Permissions be adjusted by the Applications on the fly?Here's my reason: say I have an application that is allowed to do "x", "y", and "z" (SMS, sockets, etc) Permissions. Now lets say I have a logical "user" that connects to this Application, and I want that user to only be able to do "x" and "y", but not "z" Permissions. It would be nice to have the Android Framework handle that instead of having a bunch of "if's" in the App code.
View 1 Replies View RelatedI developed and published a game about two months ago. Since then, I've received several negative comments about input lag in the game. Before releasing the game, I already took several measures to hopefully prevent lag from occurring: 1) Game is almost entirely written in native code 2) After initialization, my process never invokes the GC during gameplay (no GC executions from my process show up in the log) 3) Average FPS is generally > 30 fps 4) I tested the game on both a Motorola Milestone and an HTC Magic and I don't experience any noticeable input lag (except perhaps when the GC is executed by other processes) My guess is that the lag that users are experiencing is a result of the GC being invoked by another process. Has anyone been able to address this issue? Specifically, have any game developers been able to achieve a completely lag-free game and thus avoid negative ratings that drag down your app? The only other suspicious thing I've noticed is the following lines showing up in my log any time a SoundPool clip is played: D/AudioHard wareMot ( 1054): AudioMgr:AudioStreamOutMot::standby called D/AudioHardwareMot( 1054): AudioMgr:Output 0xb538 entering standby D/AudioHardwareMot( 1054): AudioMgr:Closing stereo device D/AudioHardwareMot( 1054): AudioMgr:Output 0xb538 exiting standby

I know that there are some experimental applications that use DDMS and achieve a framerate of 5-6 fps. This framerate is completely insufficient for my purposes since the application has smooth animations that i would like to show. Is there anyone that has found a way to do a real time screen capture on android? Should I settle for a capture of the emulator or a real video done with a real camera?
