How can we hide logs?

Example:
wave length = 1712
waveHeader[0] = 1
waveHeader[1] = 0
waveHeader[2] = 16000
waveHeader[3] = 160
waveHeader[4] = 651
Total scaled samples: 1302
waveHeader[0] = 1
waveHeader[1] = 0
waveHeader[2] = 16000
waveHeader[3] = 160
waveHeader[4] = 856

First thanks for the awesome package , i see that the package extract the wave form audio to a wave file . i wonder if there is a way to extract the wave as (uint8list ) format . Kind regards

For starters, thanks for this great plugin.

I'm encountering a problem on Android only, when i extract the data from the audio file I get this error

PlatformException(Attempt to invoke virtual method 'int java.lang.Integer.intValue()' on a null object reference, null, null, null)

I'm using the same code from the example with a few modifications

final audioFile = File(widget.audioFilePath);

    try {
      final dir = await getApplicationDocumentsDirectory();
      final waveFile = File('${dir.path}/waveform.wave');

      JustWaveform.extract(
        audioInFile: audioFile,
        waveOutFile: waveFile,
        zoom: WaveformZoom.pixelsPerSecond(
          pixelPerSecond.ceil(),
        ),
      ).listen(_progressStream.add, onError: _progressStream.addError);
    } catch (err) {
      _progressStream.addError(e);
    }

I'm having this problem on an Android device on 9.0.

Many thanks.

Hi, I am first tring flutter develop and just_waveform. I tried to run example but it got error message: Unable to load asset: audio/waveform.mp3. Can help me to know where I got wrong?

I just added that package on my flutter project. Awesome package. But I met to frozen waveform generate on 99% while creating. If anyone has some solutions for that, Please let me know.

When I try to load an mp3 file around 3mb it returns the error PlatformException(ExtAudioOpenURL error, ExtAudioOpenURL error, null, null)

Have you tested with any max large files?

Hi. I get this error when try extract file from audio.

PlatformException(ExtAudioOpenURL error, ExtAudioOpenURL error, null, null).

This is only in the iOS version. Everything works fine on android.

Thera are my files path:

file:///Users/user/Library/Developer/CoreSimulator/Devices/DAB4C89D-6849-460A-A4C7-C1E2D7A81125/data/Containers/Data/Application/D7974DA8-ED71-480B-B289-36CE72899032/tmp/BDC72317-B389-4F46-8CE3-1A24A37172A9.m4a

I am working on a simulator, can this be the problem?

I'm gettings songs with flutter plugin on_audio_query which returns song.uri likes ipod-library://item/item.flac?id=4724756324520404040, how can I extract wavefrom from this.

Thanks.

I am trying to get a visualization bar in my app for audio. I am checking out your plugin and in the example page you have a line..

final progressStream = BehaviorSubject<WaveformProgress>();

Where does BehaviourSubject come from? I searched the page and that was the only reference to the name anywhere

Hello,

Thanks a lot for your nice plugin. One question: Is it possible to render the waveform for an audio-stream that is being recorded? I use your package just_audio and the package record: ^3.0.3 to do recordings.

Best regards, MapperMalte

In my app I use aac codec or audio format files and i will like to get the wave form so i am see the use of mp3 in the examples and i am led to believe thats the only codec supported ?

I have added that package to my flutter project. But when move before and next page, I met a issue for percent change one. The percent value is return the previous and current ones. Could you help me for that issue?

Hello,

Thank you for this plugin.

We create an app of meditation and sound relaxing named Evolum (4.9 stars in stores). We wanted to add audio wave in our app. As you know we can't get the audiowave file on the file directly in the app when an user want to relax.

We have a dashboard where internal user can upload audio to be available in the app.

This dashboard is web so we can't generate the audiowave file so we wanted to do by deploying our dashboard in macOS but some of our internal user have only window...

We try to doc something with Google Cloud function when a file is uploaded in our storage with that

https://github.com/bbc/audiowaveform

but we didn't successed...

So if adding window support is not a big challenge maybe that can be usefull for us.

Thanks,

Thanks for this awesome plugin.

Also add the method to cancel the ongoing extraction. If it is possible to cancel the extraction without adding any new method then please mention it in the documentation.
