flutter plugin awesome mobile ios android audio-recorder

audio_recorder's Introduction

Audio recorder

Record audio and store it locally

Usage

To use this plugin, add audio_recorder as a dependency in your pubspec.yaml file.

Android

Make sure you add the following permissions to your Android Manifest

<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

iOS

Make sure you add the following key to Info.plist for iOS

<key>NSMicrophoneUsageDescription</key>
<string>Record audio for playback</string>

Example

// Import package
import 'package:audio_recorder/audio_recorder.dart';

// Check permissions before starting
bool hasPermissions = await AudioRecorder.hasPermissions;

// Get the state of the recorder
bool isRecording = await AudioRecorder.isRecording;

// Start recording
await AudioRecorder.start(path: _controller.text, audioOutputFormat: AudioOutputFormat.AAC);

// Stop recording
Recording recording = await AudioRecorder.stop();
print("Path : ${recording.path},  Format : ${recording.audioOutputFormat},  Duration : ${recording.duration},  Extension : ${recording.extension},");

Encoding format

For now, the plugin only use the AAC compression to encode audio. You can specify the extension of the output audio file in the file path that you give to the start method. The recognized extensions are :

.m4a
.mp4
.aac

If the file path does not finish with these extensions, the ".m4a" extension is added by default.

Exceptions

The start method raise an exception if :

A file already exists at the given file path
The parent directory of the file path does not exist

audio_recorder's Issues

Enum case 'granted' is not a member of type '() -> AVAudioSessionRecordPermission'

switch AVAudioSession.sharedInstance().recordPermission{
           case AVAudioSession.RecordPermission.granted:
               print("granted")
               hasPermissions = true
               break
           case AVAudioSession.RecordPermission.denied:
               print("denied")
               hasPermissions = false
               break
           case AVAudioSession.RecordPermission.undetermined:
               print("undetermined")
               AVAudioSession.sharedInstance().requestRecordPermission() { [unowned self] allowed in
                   DispatchQueue.main.async {
                       if allowed {
                           self.hasPermissions = true
                       } else {
                           self.hasPermissions = false
                       }
                   }
               }
               break
           default:
               break
           }

I'm trying to build for IOS, but keep coming across these exceptions:

Enum case 'granted' is not a member of type '() -> AVAudioSessionRecordPermission'

Enum case 'denied' is not a member of type '() -> AVAudioSessionRecordPermission'

Enum case 'undetermined' is not a member of type '() -> AVAudioSessionRecordPermission'

Any help would be appreciated,

Thanks

active development?

Is this repo in active development:?

I see some pull requests ect.. but no response from you.

Change wording "You must accept permissions" to "enable permissions for microphone and storage in phone settings"

Added these to four files but can't get past SnackBar message:

<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

Android Studio for Flutter.

No permissions to record audio

Hello Jordan, I am not able to get permissions to record audio with your example.

Also, I did include the permissions in the manifest:

<uses-permission android:name="android.permission.INTERNET"/> <uses-permission android:name="android.permission.RECORD_AUDIO"/> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
I tried with an emulated Pixel 2 XL and a real Pixel with the same result.

I am not an expert Android developer, but I don't see any ContextCompat.checkSelfPermission in your plugin. Could that be the problem?

Thanks in advance

Update pubspec.yaml to include Dart 2.0

As far as I can tell, a few of the past commits have brought this plugin up to date with the current Dart version, and should therefore be updated to reflect that so it can be safely used in up to date Flutter apps.
If I am wrong in this, let me know if there is any way I can help the process along and I would love to contribute.

java.lang.RuntimeException: start failed

if I try start recording for two times, the first try succeeded but the second try throw exception, even the output file of the first try isn't a valid file.

Audio quality

Hi,
First, I would like to thank you for the awesome plugin.

Is there anyway to enhance the audio quality?
I compared the recording of this plugin with android recorder app where the recording of the latest sounds better. I just used the example here.

Thanks

Excuse me, How can I fix this problem?

Size : Zero octets

Hi Everyone,

i'm facing a problem for 1 week.
Recording start and stop correctly, i get the exact duration but when i upload the audioFile in Firebase Storage, i can see the size equal to zero.
Microphone permission is granted, and no have idea when this issue would come from.

Thanks for your help.

SwiftAudioRecorderPlugin.swift build issues

Please, you need to change the lines 39 and 67 respectively as below:

39 - try AVAudioSession.sharedInstance().setCategory(.playAndRecord, options: [])

67 - switch AVAudioSession.sharedInstance().recordPermission{

This is the correct implementation. Your current build is wrong and crashes.

Error: A constructor invocation can't have type arguments on the constructor name.

I am getting following error after including the plugin

doesn't return proper audio file on iOS

My app is able to record and save on Android, but not on iOS.

When stopping record, it returns a empty audio file with .m4a saying
File length: 28
When I open the file, it does not start anything

Any help will be appreciated

Reverse audio?

Is there a way to reverse audio after recording?

Is it possible to change audio quality(bit rate.. etc)?

Example android build problem (fix)

FYI: The build of the example for android has some gradle config problems due to breaking changes of the package dependency path_provider as of version 0.3.0.

Using these instructions, the following diffs allowed me to run the example (though I had to enable access to the mic and storage manually after installing):

This package needs to be updated to file: ^6.0.0-nullsafety.2

Package audio_recorder depends on file: ^5.0.4

As per Flutter 1.22 this needs to be updated to file: ^6.0.0-nullsafety.2

Widget tests are failing

Because testWidgets() is not run in real time, it appears to be not possible to make dart async calls to file system when testing widgets. Since this plugin accesses the file system in dart code, my tests for widgets that use this plugin are failing, for example, when calling AudioRecorder.start().

Google provides a file system abstraction package that addresses this problem. I was able to use this package to get widget tests to work (using mocking). Required making a minor change to the plugin's dart code (1 new line, 1 modified line, no change to API).

I can do a PR for this if interested (or add to existing PR #17). Let me know 👍

Instructions on the dart package README is out of dead

Instructions on the dart package readme says:
import 'package:flutter_audio_recorder_plugin/flutter_audio_recorder_plugin.dart';

but the example says:

Recording fails to save to file when running on physical iPhone

The library works great when running in iOS simulator. But on a physical iPhone, it is only creating a 28 byte mp4 file which is basically the header information. None of the actual audio content is getting written to the file.

I am including the NSMicrophoneUsageDescription key and have permission enabled for the microphone.

There are no errors reported by the library, but I see several of these messages in the console after starting the recording:

mediaserverd 1111: AudioConverterNew returned -50
Other reports suggest that these message indicate the system might be having trouble accessing a microphone. But I have an Xcode app that can successfully record on the same device without this problem.

Can't play audio recorded on Android

Hi, this plugins works for me except when a file was recorded on an Android and than played on an iPhone. I can record/play within an iPhone, I can record/play within android. I can reproduce in an Android audio recorded on an iPhone but I can't reproduce on an iPhone audio recorder on an Android. I hope the tong twist makes sense

I tried both playing the file straight from http and also downloading it locally and playing it afterwards.

Any ideas?

PS: My code is pretty vanilla from the example hence why I didn't include it

Critical: This project has no license

Technically at the moment this project is proprietary because it has no license.

Please add an open source license.

Add MediaRecorder.AudioEncoder.AAC support in Android

Android record default encoder is AMR，so if record in android, can't play in IOS.

`audio_recorder` does not specify a Swift version and none of the targets (`Runner`)

Hi guys,

found following error while trying 'pod install' in the /ios folder - Any fixes?

Unable to determine Swift version for the following pods:

Missing License in Flutters showAboutDialog

Thanks for your great work!

I just wanted to add this plugin to a project, but unfortunately, the license is missing in the automatically generated licenses dialog in Android.

For demonstration purpose, the source of a minimal example:

pubspec.yaml:

name: arlicense
description: A new Flutter project.
publish_to: 'none'
version: 1.0.0+1

environment:
  sdk: ">=2.7.0 <3.0.0"

dependencies:
  flutter:
    sdk: flutter
  audio_recorder: ^1.0.2

dev_dependencies:
  flutter_test:
    sdk: flutter

flutter:
  uses-material-design: true

main.dart:

import 'package:flutter/material.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
        title: 'ARLicense',
        theme: ThemeData(
          primarySwatch: Colors.blue,
          visualDensity: VisualDensity.adaptivePlatformDensity,
        ),
        home: Scaffold(
            body: Center(
                child: Builder(
                    builder: (context) => FlatButton(
                        onPressed: () => showAboutDialog(context: context),
                        child: Text("showAboutDialog"))))));
  }
}

Steps to reproduce:

Click on showAboutDialog
Click on View licenses
Scroll down.
=> You will find
audio_recorder
TODO: Add your license here.

I saw, that you already added a license to the project (- I think it is BSD?) - but as shown above, it seems not working - at least for me.

Best regards
Stefan

Can't play audio recorded on android, send to server , and received from on iOS

Hi.
I am trying to send messages betweenAndroid and iOS devices in my chat app. Audio that is recorded on Android won't play in iOS.

There is no issue the other way around when messages are sent from iOS to Android.

This issue was present on flutter_sound plugin but was fixed lately. Here is the issue Canardoux/flutter_sound#155;

Unfortunately I can't use flutter sound in my app for some unknown reason. My app is complex and has many plugins this probably could be the reason.

Any help is appreciated.

Thanks.

WAV file support

Title basically. Need to support saving audio as WAV files.

Incompatible with Google Speech-To-Text API guidelines.

@ZaraclaJ I have been beating my head around the neighborhood trying to find an audio recorder that is compatible with Google Speech-to-text cloud API. Sadly none of the formats that are supported in your recorder, qualify for the conversion.
With a lot of apps being created with firebase and flutter combo, this seems to be a bottleneck, technology-wise.
Ref: https://cloud.google.com/speech-to-text/docs/encoding
Some handy additions would be:

FLAC (best case scenario)
OGG_OPUS (size efficient + widely used in WhatsApp and telegram as well)
LINEAR16 (very handy to use)
MP3 (lossy yet most widely used globally)

Phone call interruption

@ZaraclaJ
Hi, thanks for the awesome plugin.

I have this issue:
While recording, in the case of an incoming phone call, audio gets corrupted (reduced to one sec) on iOS.

To handle this, I created this plugin https://pub.dartlang.org/packages/phone_state_i
which creates a call back for phone call states and I stop recording.

But after this, I realised that iOS still corrupting the recording, After digging more I figured that probably interruptions are not handled by your plugin. (https://stackoverflow.com/questions/31733559/handling-interruptions-with-avaudiorecorder)

I wanted to ask you if you can implement this method(handling interruptions) in the plugin?

path_provider incompatible with contacts_service 0.2.2

Hi,

I am getting issue in adding audio_recorder package to project. This is because of path_provider package is incompatible with other packages. Error details:

Because audio_recorder >=0.0.5 depends on path_provider ^0.4.1 and contacts_service 0.2.2 depends on path_provider ^0.5.0+1, audio_recorder >=0.0.5 is incompatible with contacts_service 0.2.2.
So, because securityguard depends on both contacts_service 0.2.2 and audio_recorder ^0.0.6, version solving failed.
