Cant get it to work on iOS

Hey there,

I try to implement a chat where the user can record voice messages.
I added your plugin via yarn add capacitor-voice-recorder and I have the following lines in my Info.plist:

<key>NSMicrophoneUsageDescription</key>
<string>To Record Audio Messages in Chat</string>

In my Vue file I have:

import { Plugins } from '@capacitor/core'

const { VoiceRecorder } = Plugins

VoiceRecorder.canDeviceVoiceRecord().then((result) => { alert('works') })

But VoiceRecorder is undefined on an iOS Emulator. There are other Plugins available, but not this one.
I guess there is something missing in the README. Because for Android you added the Plugin Class in the Android code.

UPDATE:
I'm using Capacitor 2.4.2 and it's also not working under Android. On Android's MainActivity.java it says:

Cannot resolve symbol "tchvu3"

On this line import com.tchvu3.capvoicerecorder.VoiceRecorder;

Can you please help me?

Thanks in advance
Nick

Add LICENSE.

Hey I was thinking why the capacitor-community doesn't have a plugin for audio recording.
capacitor-community/media#12
I will create a PR in media plugin to add the same functionality.
For which I might take some help for here. But before I do that,
I'm guessing this is open-source. Can you add the LICENSE?

A quick suggestion,
I'm afraid of using this plugin cause of maintainability.
Maybe you can also ask capacitor community to add this repo officially in order to receive more contributors.

Request: Update example & code to capacitor 3.0 syntax

How to pause recording?

I'm developing an app in which user can pause recording voice and than resume the recording from same point where it was paused. Is it possible to achieve this functionality with this plugin?

Android canDeviceVoiceRecord gives false negative

Checking out the Android version canDeviceVoiceRecord function it gives false while I can still record.
Looking at the code itself, I don't fully understand how it works.
As I can see it tries to create a MediaRecorder and then tries to start and stop it. However if I run this before asking for permission it will always fail.
So basically I don't see the purpose of the function, and in its current position (before asking for permission) it took me a lot of time to realize that I should simply not use this for right now.

When web will be supported

Thanks a lot for this plugin !

When do you plan to support web apis for voice record ?

On iOS 15.5 plugin returns empty recordDataBase64 and msDuration: 0

Hello @tchvu3,

I have noticed that on iOS 15.5 the stopRecording method returns empty recordDataBase64 value and msDuration: 0. The same code works well on iOS 12.5.5

Could you please check?

Edit: I'm using the latest version of the plugin: 2.2.0

How to prompt user for permission in order to avoid `MISSING_PERMISSION` error?

Hey there, great lib, thanks for making it.

How do I prompt the user for permission to record in order to avoid the MISSING_PERMISSION error? Do I have to manually bring up that prompt by calling a method on the VoiceRecording object? Or should Android/iOS just do it automatically once it detects permissions in the AndroidManifest.xml/Info.plist?

If the case is the latter, then what permissions do we need to add in order to voice record?

Question : How to truncate the b64 audio ?

Hello @tchvu3,

We are looking for truncate the generated audio. 🚀

1. Truncate the B64String directly

const start = result.value.recordDataBase64.slice(
  0,
  delaiSequenceDebut
);
const end = result.value.recordDataBase64.slice(
  -delaiSequenceFin
);

const audioRef = new Audio(
  `data:${result.value.mimeType};base64,${deb+fin}`
);
audioRef.oncanplaythrough = () => audioRef.play();
audioRef.load();

--> We hear nothing

2. Truncate an ArrayBuffer

// decoding
const binaryAudio = window.atob(result.value.recordDataBase64);
const lengthBinary = binaryAudio.length;
// To bytes
const byte = new Uint8Array(lengthBinary);
for (let i = 0; i < lengthBinary; i++) {
  byte[i] = binaryAudio.charCodeAt(i);
}
let arrayBuffer = byte.buffer;

// get the first 40%
const delaiSequenceDebut = arrayBuffer.byteLength * 0.4;
let arrayBufferStart = arrayBuffer.slice(
  0,
  delaiSequenceDebut
);

// get the last 45%
const delaiSequenceFin = arrayBuffer.byteLength * 0.45;
let arrayBufferEnd = arrayBuffer.slice(
  -delaiSequenceFin
);

// Concat the 2 previous arrays
const byteStart = new Uint8Array(arrayBufferStart);
const byteStop = new Uint8Array(arrayBufferEnd);
const tmp = new Uint8Array([...byteStart, ...byteStop]);

// convert to b64 
let newRecordDataBase64 = '';
var len = tmp.byteLength;
for (var i = 0; i < len; i++) {
  newRecordDataBase64 += String.fromCharCode(tmp[i]);
}
newRecordDataBase64 = window.btoa(newRecordDataBase64);

// playing the b64
const audioRef = new Audio(
  `data:${result.value.mimeType};base64,${newRecordDataBase64}`
);
audioRef.oncanplaythrough = () => audioRef.play();
audioRef.load();

--> We can hear the start but the ending part is corrupted

Do you kown how can we process this media ?

Thanks a lot,
Eddy & Julien

Error Message - 'VoiceRecorder has no web implementation'

I have followed the exact steps as provided in angular ionic project. However, this line ->
VoiceRecorder.canDeviceVoiceRecord().then((result: GenericResponse) => console.log(result.value));

is throwing exception -
"core.js:4197 ERROR Error: Uncaught (in promise): VoiceRecorder does not have web implementation."

In the documentation, it says that canDeviceVoiceRecord() will never throw an exception. Could you please confirm whether this plugin does not support web implementation or am I doing something wrong?

Thank you so much to look into this.

Support Capacitor v4

Support Capacitor v4

import VoiceRecorder from Plugins, we have this deprecation:

@deprecated
Provided for backwards compatibility for Capacitor v2 plugins. Capacitor v3 plugins should import the plugin directly. This "Plugins" export is deprecated in v3, and will be removed in v4.

import VoiceRecorder from capacitor-voice-recorder, we have this error on native devices:
Error: VoiceRecorder does not have web implementation

On iOS the plugin does not work well with other audio playback plugins

Upon recording start, the plugin sets the AVAudioSession category to record only which prevents the app from playing sounds with other audio plugins (e.g. native-audio).
My solution was to set the category to playAndRecord but I assume the proper solution is to save the current category and restore it after recording stops.

"ERR_REQUEST_RANGE_NOT_SATISFIABLE" error on stopRecording()

Hi,

I'm trying to record some audio in a web app and sometimes when I call stopRecording the error below appears.

I made sure that the recorder was running before pausing by checking if getCurrentStatus() returns 'RECORDING' or 'PAUSED'. This behaviour seems random because it is sometimes working and sometimes not. The error also doesn't get caught by any of the error listeners for the provided functions.

My Setup:
Chrome 107.0.5304.107 (Official build) (64-Bit)
"@capacitor/core": "^4.5.0"
"capacitor-voice-recorder": "^4.0.0"

Thanks for the help in advance

Help/Question: using this plugin to play the recorded audio with capacitor native-audio

Im using the plugin to record and now want to use it with native-audio plugin for playing.
What I found as a problem?
This plugin give base64 string. I found a solution to use it with cordova https://ourcodeworld.com/articles/read/279/how-to-create-an-audio-file-from-a-mp3-base64-string-on-the-device-with-cordova
In this given solution we convert it to blob object which in turn taken by cordova FileSystem plugin to write it to a file.

Although to use it with capacitor we need to convert it to string. Because Filesystem Plugin by capacitor accepts a string as data then encodes it with utf-8, utf-16 or ascii to save it. Which can be consumed by native audio.

Implementation.

import { FilesystemDirectory, FilesystemEncoding, Plugins } from '@capacitor/core';
import { useState } from 'react';
import { GenericResponse, RecordingData } from 'capacitor-voice-recorder';
import { TextAudioFieldOperations } from '@gastromatic/ui-mobile/dist/components/TextAudioField';

const b64toBlob = (b64Data: string, contentType: string, sliceSize= 512): Blob  => {

  const byteCharacters = atob(b64Data);
  const byteArrays = [];

  for (let offset = 0; offset < byteCharacters.length; offset += sliceSize) {
    const slice = byteCharacters.slice(offset, offset + sliceSize);

    const byteNumbers = new Array(slice.length);
    for (let i = 0; i < slice.length; i++) {
      byteNumbers[i] = slice.charCodeAt(i);
    }

    const byteArray = new Uint8Array(byteNumbers);

    byteArrays.push(byteArray);
  }

  return new Blob(byteArrays, { type: contentType });
}

const useAudio = (): TextAudioFieldOperations => {
  const { VoiceRecorder, NativeAudio, Filesystem } = Plugins;
  const [audio, setAudio] = useState({recordDataBase64: ''});
  const [uri, setURI] = useState('');

  const onStart = ():void => {
    VoiceRecorder.hasAudioRecordingPermission().then((result: GenericResponse) => {
        if(result.value) {
          VoiceRecorder.startRecording();
        } else {
          VoiceRecorder.requestAudioRecordingPermission().then((result: GenericResponse) =>
            result.value && VoiceRecorder.startRecording()
          );
        }
      }
    );
  };

  const onStop = async (): Promise<void> => {
    VoiceRecorder.stopRecording()
      .then((result: RecordingData) => setAudio(result.value));
    const blob = b64toBlob(
      audio.recordDataBase64,
      'audio/aac'
    );
    await Filesystem.writeFile({
      path: 'temp.aac',
      data: await blob.text(),
      directory: FilesystemDirectory.Cache,
      encoding: FilesystemEncoding.UTF8,
    }).then((result)=> setURI(result.uri));
  };

  const onPlay =():void => {
    NativeAudio.preloadComplex({
      assetPath: uri,
      assetId: "im_batman",
      volume: 1.0,
      audioChannelNum: 1,
    });
    NativeAudio.play({
      assetId: "im_batman",
    });
  };

  const onPause = ():void => {
    NativeAudio.pause({
      assetId: "im_batman",
    });
  }

  const onDelete = ():void => {
    setAudio({recordDataBase64: ''});
  };

  return {
    onStart,
    onStop,
    onPlay,
    onPause,
    onDelete,
    onSeek: (): void => console.log('Seek'),
  }
};

export default useAudio;

I'm still getting Error 00x00 by native-audio. Or am I doing something wrong?
How can we achieve this?

How to difference permission state "prompt" from "denied"

The permission check method returns true or false, but false could be "prompt" when permissions have not yet been requested or "denied" when the user has denied them. How can they be differentiated?

Upgrade documentation about NSMicrophoneUsageDescription

Upgrade documentation about NSMicrophoneUsageDescription

See how official capcitor documentation tell about this

"recordDataBase64" sometimes contains the mimeType

Hello,

I noticed that:

• on web recordDataBase64 contains the mimeType and encoding, e.g.: data: audio/webm;codecs=opus; base64, <actual encoding>
• on mobile it it just the raw encoding

Is that working as intended?

Thanks!

Capacitor 5 + Gradle 8 support

Seems like changes in the AndroidManifest.xml and build.gradle are required to make this plugin work on Capacitor 5 for Android with Gradle 8.

The package name needs to be removed from the manifest file and added to the build.gradle file as namespace field.

problems with different mimetypes in different browsers (v4)

Hey,

i have a problem with the different encoding of the files. As far as i can tell the mime-types are different for each scenario: audio/webm (recorded with chrome, also different depending on which browser you record with.) for browser and audio/aac (with different sigantures) from android or apple devices.

We record the voice messages in different devices or different browsers and need to support as many platforms as possible, we upload them via aws s3 as the pure base64 string, then download them as these strings, create an instance of an Audio HTML object and play them. (current state)

The problem is that these files have for example different durations then the real duration or do not get played at all (only in safari an issue). The encoding of voice messages recorded by the android devices seem to work in every browser (we tested) for some reason.

Do you know of a way to record the voice messages with an encoding in e.g. Chrome that will work in Safari? Is there a way to convert this encoding, or record with a more broad possibilty to choose the encoding we want?

Questions regarding the plugin

@tchvu3 thanks for your amazing work here!

I'm about to start a simple journal app where I can record an entry and later on add some more information to that recording.
A few questions:

• After you stop the recording, where the file is saved? in a temp folder?
• If yes, can I use the "Filesystem" plugin from Capacitor to create/move this file to a permanent folder that will be created when the user install my app?

Thank you!

Error: EMPTY_RECORDING is throwed not in stopRecording

I get error Error: EMPTY_RECORDING that is throwed not from stopRecording therefore I am unable to handle such error

Limitations of the plugin

Hi there,

I'm looking to use this plugin in my next project and I wondered if there were any limitations in regards to the maximum duration of the audio file?

As I understand it from a previous question regarding file management the library creates a temp file which is then base64 encoded and then deleted. The base64 string is bubbled back up as a string to the web application and at this point is there a theoretical maximum size on this?

My use case is long audio recordings (1hr let's say) and I'm wondering if I'll face any issues.

Thanks in advance.

Sending via http post request

Hi @tchvu3 ,
Please how can I go about sending the data returned on recording stop as a file via HTTP post request?
I have tried various ways to convert the base64 data into a blob file that can be sent as form data but I think I'm missing something because every day I've tried has either led to an error or a corrupted file that cannot be played.

I would appreciate it if you can give me a summary of how you intended for the data to be transferred via HTTP requests.
Thank you in advance.

Add info to documentation about required RECORD_AUDIO permission

API enhencement request

This plugin is what I was searching for some time in order to replace the old deprecated cordova plugin media, but some functions are missing for a complete API:

• Functions for pausing and resuming recording, it seems possible since the the MediaRecorder class support pause and resume methods.
• Add parameters to VoiceRecorder.stopRecording to change the return value format. In my case I will record for dozens of minutes and the base64 encoded string will be really too large, it would be nice to have a parameter to specify that we want to move the temporary file to another location instead of returning its content. For example VoiceRecorder.stopRecording() could take an options object like

interface StopOptions { 
    move?: string;
}

In this case if move is != null, the plugin move the file to the given location (this could be an URI returned by Filesystem.getUri) and return this location instead of returning the file content as encoded string.

If you don't have enough time to do it, I will try to implement this (only for Android because I have no idea how to do this on iOS).

Feature request: live steam/mic input while recording

I'm using wavesurfer.js to render the final recording. Could there be a way of providing a live stream, or mic volume to the app from this plugin? Has anyone done anything similar? So that the user can see that they are being recorded.

Thanks
Nic

problem on ios real device, on stop recording i get an audio of 1 second only

How I can get audioCotext raw data ?

How I can get audioCotext raw data While recording ?
I need to get audio Contex raw data for using in javascripts method like

Unexpectedly found nil crash

I've found this plugin fatally crashes when my phone is in an audio call and I try to record an audio. I've got everything wrapped in try catch blocks and it still fatally crashes the app.

Xcode throws an error here, something about trying to implicitly unwrap nil

    public func stopRecording() {
        do {
            audioRecorder.stop()
            try recordingSession.setActive(false)
            try recordingSession.setCategory(originalRecordingSessionCategory)
            originalRecordingSessionCategory = nil
            audioRecorder = nil
            recordingSession = nil
            status = CurrentRecordingStatus.NONE
        } catch {}
    }
    ```

Feature Request: Provide option to not save recording to file

Hello!
We're doing a POC that has a special restriction on recorded audio: the audio cannot be saved to the device. Wanted to see how hard it would be to add an option for returning the raw recording data as base64 or a data URL instead of saving it to the device temp directory. Here's how the official Capacitor camera plugin handles this for reference. Thanks!
