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.
