firezenk / audiowaves Goto Github PK

Nice project.

a)
How would one Increase the sensitivity as it currently does not fire very well with normal conversation.
b)
Would it be possible to slow down the vertical drop of each bar so it has a better visual effect ?
Currently the spikes disappear very quickly so it is almost difficult to see them.

thanks

I tried :

1. Adding maven { url 'https://github.com/FireZenk/maven-repo/raw/master/'} in build.gradle (Project) [No errors] but can't add Visualizer to Layouts.
2. Also adding compile 'org.firezenk:audiowaves:1.1@aar' in build.gradle (Module) . [Error] Failed to resolve org.firezenk:audiowaves:1.1
3. Only adding compile 'org.firezenk:audiowaves:1.1@aar' in build.gradle (Module). [Error] same as above.

I have also a conflict .When I use Media Recorder along with this lib,IIegalStateException is occurred and I cannot record the voice.

Hello!

Thank you for sharing your work!

I am struggling to make it work in parallel with audio recording. I get MediaRecorder IllegalState exception again and again.

I am using your visualiser this way:

 private void startRecording() {
        mRecorder = new MediaRecorder();
        mRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
        mRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
        mRecorder.setOutputFile(mFileName);
        mRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_WB);

        try {
            mRecorder.prepare();
        } catch (IOException e) {
            Timber.e("prepare() failed");
        }
       mRecorder.start();
       mVisualizer.startListening();
    }

    private void stopRecording() {
        mVisualizer.stopListening();
        mRecorder.stop();
        mRecorder.release();
        mRecorder = null;
    }

What do I do wrong?

when build sample on my phone (api17) , return null for dispatcher in prepare and crashed sample,

Can you build an api to render the views, from a data set that is inputtable to your api, and thus remove the dependency from the DSP library that you are using?

Standard random number generators do not provide a sufficient amount of entropy when used for security purposes. Attackers can brute force the output of pseudorandom number generators such as rand().

Hi,
I'd love to use your library in my android app but I have played a little bit with it and I found some problems.

The first is connected to the issue #1 :

• starting with Android 5.0 we have to manage the runtime permissions and so, due to the fact that your widget uses the microphone when the layout gets inflated, it will fails every time you starts the app on Android 5.0 (the first time you don't have any permission like RECORD_AUDIO when you start the app the first time ). Have you ever try the library in this scenario?

The second is connected to the issue #3 :

• I think the point here is that if the widget starts to use the microphone when it gets inflated (method prepare()) you will never had the possibility to use the microphone for something else like in my case a voice recognition activity. It could be ideal to have the possibility to start and stop the entire service whenever we need to avoid multiple concurrency on the same resource (microphone). And by the way even with the current implementation it seems that the stopListening() method is not working at all.

I like the graphical part, I think is one of the best "on the market" at the moment (maybe the only one) so I really appreciate your work. Do you think we can improve it? Let me know if you need help, I will be happy to give you an hand!

Thanks!

This sample example is working fine but I want to attach it with playing media not with microphone, which means if the user is using earphones then also it will work as it is working with built in speaker(because right now mic captures sound coming from built in speakers). is there any possibility of doing so with this library?

Hi!

Thank you a lot for your sharing your work!

stopListening() does nothing. The visualizer is still updated.

Context :
I want to start listening when I click on the start button, then stop when I click on another button.

Did anybody face this behavior?

public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, Bundle savedInstanceState) {
    view = inflater.inflate(R.layout.record_sound, container, false);
    visualizer = view.findViewById(R.id.visualizer);

    view.findViewById(R.id.start).setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            visualizer.startListening();
        }
    });

    view.findViewById(R.id.stop).setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            visualizer.stopListening();
        }
    });
    return view;
}
