You can record audio locally on the client side using the LiveKit Swift SDK with several approaches: • LocalAudioTrackRecorder: Capture audio from a local audio track and stream it as data. You can process or save this data as needed. • AudioMixRecorder: Record audio directly to a file, supporting multiple audio sources and real-time mixing. • AudioManager: Manage the underlying audio engine and start/stop local audio recording without joining a room. Example for recording audio to a file:

let audioSettings: [String: Any] = [
    AVFormatIDKey: kAudioFormatMPEG4AAC,
    AVSampleRateKey: 16000,
    AVNumberOfChannelsKey: 1,
    AVLinearPCMBitDepthKey: 32,
    AVLinearPCMIsFloatKey: true,
    AVLinearPCMIsNonInterleaved: false,
    AVLinearPCMIsBigEndianKey: false,
]
let recordFilePath = URL(fileURLWithPath: NSTemporaryDirectory())
    .appendingPathComponent("recording.aac")
let recorder = try AudioMixRecorder(filePath: recordFilePath, audioSettings: audioSettings)
try recorder.start()
// Add audio sources and record...
recorder.stop()

Audio recording is fully supported with these methods. Currently, the SDK does not provide a built-in method for local video recording on the Swift client. Sources: Sources/LiveKit/Track/Local/LocalVideoTrack.swift | sample-app-record-local/README.md
