[MathJud]

In Chat's the user should be able to send voice messages in direct chats.

• Record a voice message
• Send the voice message as a chat file
• Make voice message playable from the GUI

Testing

• Voice-Message Size: Encoding, Bitrate, Samplerate #643
• Voice Message: Needs loading animation #644

@sukhman-sukh Thanks a lot for this offer.
I assigned you to the issue.

@MathJud Sorry for delay. I was working on the issue and went though code base. While implementing the record feature I am using import 'package:record/record.dart'; which is using await record.start(const RecordConfig(), path: 'aFullPath/myFile.m4a'); to start recording.
I want to know what path should I specify.
Is qual storing any messages on user end at any location?

Thanks for your work! The file should be saved locally and then handed over via RPC to libqaul.

1. record the file into the local flutter app storage.
2. send the path to the recorded file via to a chat group using the protobuf RPC message chatfile > SendFileRequest (see

   qaul.net/rust/libqaul/src/services/chat/chatfile_rpc.proto

   Line 32 in 0da91d6

   message SendFileRequest {

   )

• the file will then be copied by libqaul into the libqaul storage, will be encrypted and sent to the chat group.

[MathJud]

In order to hand the file over to libqaul for sending:

• There is a function in the libqaul_worker to send the file to libqaul (see

  qaul.net/qaul_ui/packages/qaul_rpc/lib/src/libqaul_worker.dart

  Line 261 in 0da91d6

  void sendFile({

  )
• the file sharing dialog is using the same function (see

  qaul.net/qaul_ui/lib/screens/home/tabs/chat/widgets/file_sharing.dart

  Line 54 in 0da91d6

  worker.sendFile(

  )

The feature is almost ready! Thanks to @sukhman-sukh & @brenodt !
The tests have shown the following discussion points and problems that need to be resolved:

• Voice-Message Size: Encoding, Bitrate, Samplerate #643
