Build a Spatius Backend with Go

Go Server SDK can be evaluated with Spatius through the documented backend runtimes boundary described below. Use the linked first-party references as the implementation source of truth.

Integration boundary

What connects to what

The Go SDK exposes backend sessions, PCM or Ogg Opus handling, motion callbacks, and LiveKit or Agora egress for teams that own the voice pipeline.

Go Server SDKaudio / session boundarySpatius Motion Servermotion + synchronized audioAvatarKit client rendering

Prerequisites

  • Current Go Server SDK credentials and access
  • Spatius App ID, Avatar ID, and an approved session-token flow
  • A defined audio source, format, sample rate, and interruption policy
  • A test environment that matches the target browser, device, or server runtime

Implementation path

Build a testable baseline

  1. 1

    Confirm the current Go Server SDK version and read both linked first-party sources.

  2. 2

    Run the smallest official Spatius sample without the partner dependency to establish an avatar baseline.

  3. 3

    Connect Go Server SDK at the audio or session boundary described in the architecture section.

  4. 4

    Verify audio format, pacing, interruption, reconnect, cleanup, and credential isolation.

  5. 5

    Record versions, target devices, network conditions, failures, and rollback behavior before production.

Decision guidance

Best for and not best for

Best for

  • Teams already committed to Go Server SDK
  • Developers who want to keep the avatar layer separable from the conversation stack

Not best for

  • Teams requiring an unverified integration to be treated as production-ready
  • Buyers looking for a fully managed end-to-end avatar-video service

Evidence-aware assessment

Advantages and limitations

Advantages

  • Adds a Go Server SDK-specific implementation decision instead of a generic provider list
  • Keeps the Spatius rendering boundary explicit
  • Provides a concrete validation and failure checklist

Limitations

  • The demo repository does not contain a complete Go ASR → LLM → TTS application. Present this as an SDK integration guide, not a turnkey Go agent.
  • Current package and API versions still require release-time verification
  • No first-party benchmark for this exact combined stack is included in the supplied evidence
Validation disclosure

The demo repository does not contain a complete Go ASR → LLM → TTS application. Present this as an SDK integration guide, not a turnkey Go agent. Indexing this guide does not convert an architecture blueprint into a claimed native connector; run and document the validation checklist before production use.

Page-specific FAQ

Implementation questions

Is Go Server SDK a native Spatius connector?

The supplied evidence classifies this as a documented path. Recheck the linked first-party sources for the current support boundary.

What must be tested before production?

Credentials, audio access and format, sample rate, interruption, reconnect, backpressure, cleanup, privacy, versions, and target-device behavior.

Does this page include performance results?

No. It does not publish latency, FPS, bandwidth, or reliability numbers for this exact combined stack without a reproducible first-party test.
