Screen and audio cast for Google Glass app demo - android

I am working on my Glass app demo and I used droidAtScreen to project the screencast from MyGlass for the presentation. The problem is that I cannot demonstrate the voice responses from the Glass based on user input. My backup plan is to record a video for demonstration and insert the voice output manually. Does anyone know if there is a better way to do both screen and audio cast for Google Glass app demo? Thanks for the help.

Have you tried Android Screen Monitor? I always use ASM.jar for any demonstration and it works fine with both audio and video demonstrations.
The link to download ASM.jar is here.
Detailed description is here. If you're using Droid#Screen than probably you know how to run Android Screen Monitor (ASM.jar), but here is a link for a reference that explains the process in detail.

This is how I solved the problem initially.
Use Screencast-O-Matic to record the video of screencast on my
laptop. The screencast is done using DroidAtScreen with
highest frame rate possible option checked. It has better frame rate than ASM screencast. During the video record session, my voice was captured. (so in other words, choose a
quiet place!!)
For simulating the Text-to-Speech engine voice, I used SitePal
demo site and the voice is Julie (US). It's the closest voice I could
find that matches the Google Glass speech engine. To record the
voice, I used Audacity and export it to .wav audio file. The key
is to play the video and find the exact time to insert the audio
file using any standard movie maker software.
UPDATE
Just finished the demo presentation at IT Expo. To my surprise, the simplest solution worked the best.
Create the video demo (under 2 minutes) as mentioned above but insist
on asking an audience to try it out.
Ask the person to say what
he/she heard from the Glass app as a response to the action (ex. The
item is saved)

Live phone Call caption / transcription (speech to text) on Android

This question is to help the "Hard of hearing community" so that they can READ the phone/mobile call because they can not hear it.
Android 11 provides an API "AudioPlaybackCaptureConfiguration". This API gives apps the ability to copy the audio being played by other apps.
Google also implemented the same on Pixel mobiles as shownn here - https://www.youtube.com/watch?v=7hb3p8LZIq8 . But it has few limitations -
It supports only english language, How to enable support for the regional language
The current implementation translates voice to text using a local mobile engine i.e. voice is not going to google server(all the processing is happening offline in mobile itself), so accuracy is also low.
After seeing a lot of posts here it seems developers are facing issue while implementing the same to capture the caller voice and then transcibe it due to some restriction by Google.
How to record internal audio on Android devices or record MediaPlayer Audio Stream?
Is there anyway to capture the caller voice (https://developer.android.com/guide/topics/media/playback-capture#allowing_playback_capture) ? Like in the youtube video I shared above, Google must be capturing caller voice and its offline engine is processing that voice and converting it to text. So can we capture caller voice using some way and then send that voice to some server API or to Google Live Transcribe app (or whatever it is) for better accuracy and then the converted text will be displayed on the screen (as per user choice of language).
I am also a developer though not a mobile one. So some terminology may be wrong , please excuse it and provide your suggestion.
Can we modify the Android source code itself according to our requirement and remove that limitation so that we can achieve what we want to do even if it require to build custom Android OS ?

Android capture internal (application) audio

I want to capture internal audio, programmatically. For instance, I want to play an audio file (on my device) and then capture the audio output - not using the microphone with the volume turned up.
Example use case: I want to make a library that other developers can use in their games, allowing users to record in-game audio.
Android says there is Playback Capture functionality, however, I just cannot find an example. I've googled for hours. Whenever I google 'android capture app sounds' or 'android record audio', I either get links to voice recording apps or some code recording from the microphone (usually nearly 10 years old)... e.g
Does anyone have a link to a working example?

How can I record a video with sound of my app using Android Studio?

I am developing an app with Android Studio 2.1 and I would like to record a video of an usage example, with sound.
I have already recorded some videos, but always without sound. As the sound in my app is a key feature, I would like to have the video with the audio output of my app.
Is it possible? In case it is, how could I use it?
Thanks!
Maybe you should try using external app for recording both screen and sound. I have dig in just few mins and i have found some apps.
Here I left link to a top http://www.androidauthority.com/best-screen-recording-apps-600838/
The last one seems to be the one you are looking for (SCR Screen Recorder, which requires root), hope it works!
Other option could be to use a male to male audio cable and record the audio transmitted to the pc.

android audio track wont output beyond a certain frequency

I have create an app for android that creates and stores a single tone, then plays it back utilizing android audio track class. Here's the issue: on my phone I can only play tones up to a frequency of about 11kHz, and on a virtual phone run from my PC (same exact code) I can get frequencies up to about 14kHz. What could cause this cutoff?
Using a tone generator app from the market, my phone can produce up to 20kHz signals, so I know it is not a hardware issue.
Thanks.
It might help if you provide some of the code for how you're generating the tone.
For audio stuff, you should go here http://music.columbia.edu/mailman/listinfo/andraudio and signup then ask there. There's a great community of Android developers for that list all dedicated to audio development.
Also, self-promotion, I run a forum website (relatively new and needing updates) and I plan to add an Android Audio forum on it once I get enough interested folks. If you're interested, sign up here

Live streaming using android Device

I have been working on an android app that streams videos live on a server using android built-in camera and anyone can watch that live stream from my website which is deployed on the server.
So can any one help me on how should i start working on my project because at present i have no direction to start with.
More specific example is:-
Like a person goes to a picnic and he wants his friends and family to see whats going on with the tour and his family can see live what he's doing live.....
There is an open-source project that does a very similar thing:
http://code.google.com/p/ipcamera-for-android/
It basically uses the LocalSocket of the camera to read the video and stream it from a webserver. You should be able to find lots of information in the source code.
If you want to stream over the internet, for everyone to see i can recommend you the service justin.tv which lets you broadcast you stream to the whole internet. If tried it, and it works very good!
However, if there's no wifi you will probably have a very laggy connection, unless you convert the video in a smaller size...
