Side by side

What it is
audioproxy:Audioproxy renders audio variants on demand via signed URLs, streaming and caching them without a job queue.
Layercode CLI:Layercode CLI lets you create, test, and deploy voice AI agents from the terminal with built-in tunneling and edge-native audio delivery.
Best for
audioproxy:On-demand audio variant rendering
Layercode CLI:CLI-driven voice AI agent development
Who it’s for
audioproxy:Developers needing on-the-fly audio transcoding and variant generation.
Layercode CLI:Developers building voice AI agents who want fast local testing and zero infrastructure setup

audioproxy features

  • URL-based API. All variant options are encoded in the URL, which also serves as the cache key.
  • Streaming render. The first request streams encoded audio while it is being generated.
  • Cache & range support. Subsequent requests hit a cached file with full range-request capability.
  • S3 or directory source. Reads source files from a mounted directory or any S3-compatible bucket.
  • Audio processing options. Supports format, bitrate, VBR, resample, trim, fade, gain, loudness normalization and speech enhancement.
  • Peak data format. Can output waveform min/max pairs as JSON or binary for UI rendering.
  • Health & metrics. Provides /health, /ready and Prometheus metrics endpoints.
  • Signed URLs. Requests are signed GETs; signatures are excluded from the cache key for shared variants.

Layercode CLI features

  • One-command init. Create a voice AI agent with a single CLI command, including real-time speech-to-text and text-to-speech.
  • Built-in tunneling. Local testing via an integrated tunnel eliminates manual webhook URL copying.
  • Sample backend. Provides a starter backend that processes transcripts and generates responses based on prompts.
  • LLM-agnostic. Use any large language model while retaining full control over agent logic and tools.
  • Edge deployment. Deploys audio processing to 330+ global edge locations with ~50 ms latency.
