What we do

Measurement and verification, built for audio

Podcast advertising is bought on trust. We replace that trust with evidence.

Audio Analysis

We fetch audio files at scale, transcribe them with high accuracy, and extract signal metrics from loudness to silence. Every episode becomes structured, searchable data.

How it works

From audio file to verified evidence

A single automated pipeline handles every episode we monitor.

Fetch

Audio files are collected automatically from podcast RSS feeds, hosting CDNs and ad servers, then normalized for processing.

Transcribe

Speech-to-text with word-level timestamps turns every episode into an accurate, timecoded transcript.

Analyze

Ads are detected and matched against scripts; audio quality is measured; content is classified for brand safety.

Report

Verification results, quality metrics and suitability scores are delivered through dashboards, scheduled reports and API.
