Authio vs IRCAM Amplify: AI Music Detector Comparison

Authio is the production AI music detection pipeline for music distributors, record labels, and DSPs. Every release entering the Forward Digital distribution pipeline runs through Authio before delivery to 110+ DSPs. The system publishes 99.42% accuracy on the 12-model forensic ensemble, sub 0.6% false-positive rate, and approximately 4.5 seconds of GPU-accelerated per-track latency, measured continuously on that deployment.

IRCAM Amplify's published accuracy figure has appeared as 97.6%, 98.5%, and 99% across different sources and dates, currently 99% on its product page. None of those three figures is paired with a public benchmark dataset or held-out methodology. Below is a side-by-side on the metrics that matter for catalog ingestion at distribution scale, with every IRCAM Amplify claim cited verbatim from its product page or from press coverage.

Authio vs IRCAM Amplify at a glance

Published accuracy figures: a moving target

Three different accuracy figures appear across IRCAM Amplify's official channels and press coverage. The product page lists 99 percent. Music Business Worldwide reported 98.5 percent in May 2024. Industry coverage cites 97.6 percent.

None of the three figures is accompanied by a published benchmark dataset, dataset size, or held-out methodology. The product page also does not specify whether the false-positive figure ("less than 1 percent") is measured against the same dataset as the accuracy figure.

Authio publishes 99.42 percent accuracy and sub 0.6 percent false-positive rate measured continuously on its production deployment at Forward Digital. The 12-model forensic ensemble scans every release entering the distribution pipeline before delivery to 110+ digital service providers, with detection signatures derived from per-platform spectral artifacts: Suno's digital haze and 32 kHz characteristic, Udio's transformer-pattern markers, MusicGen's 50 Hz EnCodec token boundaries, ElevenLabs Music's neural vocoder fingerprints, and Stable Audio's diffusion-process latents.

AI generators detected: Authio vs IRCAM Amplify

Authio trains a dedicated detection model for each named AI music generator listed below, plus a generic detection layer that handles emerging generators as new platforms enter the market.

• Suno: text-to-music generator with vocal synthesis
• Udio: transformer-based music generation, instrumental fidelity
• MusicGen: Meta's open-source autoregressive model
• ElevenLabs Music: ElevenLabs music generation arm
• Stable Audio: Stability AI diffusion-based generator
• Mureka: full-length song generator
• Riffusion: real-time spectrogram-to-audio generator
• MozartAI: AI music generation platform; detected via model-specific signature analysis
• Emerging generators: a generic detection layer flags new and unattributed AI music output as new platforms enter the market

IRCAM Amplify lists "Suno, Udio, Sonauto, Eleven Labs, and more" on its product page (accessed May 2026). The product page does not enumerate the complete set of generators detected.

API access and SDK comparison

Both vendors provide a REST API. Authio additionally publishes SDKs for Python, Node.js, and Java, with webhook support for asynchronous batch processing. Full integration details are in the Authio API documentation. Authio also provides a free in-browser checker at authio.io/ai-music-checker for ad hoc verification, with 5 free analyses per day and no signup required. IRCAM Amplify does not provide a free in-browser checker as of May 2026.

Pricing: Authio vs IRCAM Amplify

Authio publishes pricing publicly. Plans start at €15 per month for the Starter tier and scale to €3,999 per month for enterprise catalog ingestion. A free in-browser checker is available with 5 daily analyses, no signup required.

IRCAM Amplify does not publish pricing on its product page (accessed May 2026). Prospective customers contact sales for a quote.

Methodology transparency

The most reliable test of any accuracy claim is the conditions under which it was measured. Three questions to ask both vendors:

1. Where is the figure measured? Authio: continuously on its production deployment at Forward Digital. IRCAM Amplify: not published.
2. Is the system in production use at scale? Authio: yes, scanning every release in the Forward Digital pipeline before delivery to 110+ DSPs. IRCAM Amplify: no production deployment context published.
3. Are detection signatures public per generator? Authio: yes (Suno digital haze and 32 kHz characteristic, Udio transformer-pattern markers, MusicGen 50 Hz EnCodec token boundaries, ElevenLabs Music neural vocoder fingerprints, Stable Audio diffusion-process latents). IRCAM Amplify: lists generator names without per-generator detection methodology.

Authio is the distribution pipeline detector

Authio is built for one job: gate AI-generated content out of distribution catalogs before it reaches DSPs. Production deployment at Forward Digital, scanning every release across 110+ DSPs. Published 99.42% accuracy on the 12-model forensic ensemble. Sub 0.6% false-positive rate. ~4.5s GPU-accelerated per-track latency. Per-generator attribution across Suno, Udio, MusicGen, ElevenLabs Music, Stable Audio, Mureka, Riffusion, MozartAI, plus a generic head for emerging generators. REST API with SDKs for Python, Node.js, and Java. Webhook support for asynchronous batch processing. Public pricing from €15 per month. GDPR compliant, EU jurisdiction, no audio persisted to disk.

IRCAM Amplify publishes a higher batch throughput figure (more than 250,000 tracks per hour across parallel processing) and is the longer-established research-institution brand. The relevant comparison for a distributor or DSP is per-track gating latency, methodology transparency, and per-generator attribution depth. On those metrics, IRCAM Amplify has not published comparable numbers as of May 2026.
