Espressif GMF Audio Elements Module

Audio/Video Processor module for ESP-GMF

VideoSDK IoT — prebuilt Rust staticlib for ESP32-S3-Korvo-2 audio (mic capture, Opus encode, WebRTC signaling). C ABI.

Espressif ASRC Module

Streaming MP3 player for ESP32-S3: HTTP chunked download → MP3 decode → resample → PCM out, fully PSRAM-resident, with abortable lifecycle. Audio output and HTTP transport are injected via abstract interfaces, so the component is project-agnostic.

An adaptive PCM audio renderer for ESP-IDF that stabilizes jittery network streams using dynamic time-stretching (Sonic).

Multimedia Render

IoTSdk is a lightweight ESP-IDF component that enables ESP32-based IoT devices to participate in real-time meetings through the VideoSDK platform. The component provides seamless integration for joining meetings, publishing streams, and subscribing to audio from other participants.
