Audio Bug

[ProPaulFuentes]

I’m currently trying to implement the audio feature using Exyte Chat v2.7.4.
I’ve seen and followed the guidance from this issue: #198, and I updated everything accordingly.

However, the audio feature still isn’t working on my end.
The UI appears correctly, but no audio is recorded. The audio indicator remains inactive, and when checking the iPhone Control Center during recording, the microphone icon stays greyed-out at the end (as if the system never registered any audio session).

Here is the part of my implementation:

private let recorderSettings = RecorderSettings()

ChatView(messages: (translationState == .done) ? viewModel.data?.translateMessages ?? [] :  viewModel.data?.messages ?? [], chatType: .conversation, replyMode: .quote) { draft in
                print("DRAFT = \(draft)")
                viewModel.sendMessage(chatId: chatId, draft)
            } messageMenuAction: { (action: Action, defaultActionClosure, message) in
                ...
               
            }
            .setAvailableInputs([.text, .media, .audio])
            .setRecorderSettings(recorderSettings)

Expected behavior:
Audio should start recording when interacting with the audio UI component, and the microphone indicator should turn active.

Actual behavior:
UI displays correctly, but:
• No sound is captured
• Control Center sound stays greyed out
• Nothing is saved or passed to the Chat controller

Hello,
I hope you are well.
Do you have any idea where the problem might be coming from?

Hey @ProPaulFuentes, unfortunately we do not have the resources for open source right now. You are most welcome to support this library by submitting a PR adding this functionality. Have a nice day

@ProPaulFuentes try setting the codec to FLAC
i.e. change the first line from the code snippet you posted to:

private let recorderSettings = RecorderSettings(audioFormatID: kAudioFormatFLAC)

You may need to import AVFoundation to get access to the kAudioFormatFLAC constant.

For more context:

I had the same issue: the orange dot that indicates that the microphone is active wasn't being displayed, and the recording produced empty audio files.
But changing the codec to one of kAudioFormatFLAC, kAudioFormatAppleLossless, kAudioFormatLinearPCM fixed it for me.
(I tried all the available codecs, and these were the only ones that worked)

Note:

These are the logs when I try to record audio using the default codec, kAudioFormatMPEG4AAC (which doesn't work):
From logs when trying to record using default codec (doesn't work):
