Open-source AudioTrace Reveals AI Voice Agent Signals
A developer published AudioTrace, a small open-source library that analyzes voice-agent call recordings and emits a structured, typed CallReport. The tool splits audio analysis into two layers: deterministic signal-processing measurements (silence, pitch, speaking pace, latency) and learned-model estimates (transcript, speaker, sentiment, intent). AudioTrace runs locally for privacy, can be installed via pip, returns a Pydantic CallReport, and is designed to integrate with observability tooling (OpenTelemetry) and agent tracing systems (LangChain, LangSmith). The blog post is the first of a series that will detail signal-extraction approaches and how to wire voice signals into CI pipelines. The project repository is published on GitHub (github.com/dimastatz/audiotrace).
