Hi Everyone, We're experiencing low audio quality using Hedra Realtime Avatar - need guidance: Setup: - livekit-plugins-hedra with Python Agents SDK - TTS: Tries both ElevenLabs Turbo v2.5 and Azure TTS at 48kHz - Audio output: 48kHz with RED encoding enabled - Playback: Android WebView + macOS Safari (both exhibit issue) Problem: Audio sounds noisy, mechanical, distorted - despite excellent connection quality Observed: - Connection quality: EXCELLENT (both WebView and agent logs) - Codec: audio/red (confirmed in trackSubscribed) - Sample rate/bitrate: not exposed by WebRTC API Investigation: - Hedra plugin hardcodes SAMPLE_RATE = 16000 in DataStreamAudioOutput - Direct TTS playback (no Hedra) sounds perfect through same WebView - Suspect Hedra backend re-encodes at low Opus bitrate regardless of input Questions: 1. Does Hedra API support audio quality parameters we're missing? 2. Is there a way to configure Opus bitrate for Hedra sessions? 3. Are there known Hedra backend limitations on audio quality? 4. Any recommended settings for production-quality audio with Hedra? Thank you!

If you disable avatar and run your agent does the audio quality sound fine?
