# Does Tessary support audio or voice traces?

Not yet. Tessary's media support currently covers two modalities: images (PNG, JPEG, GIF, WebP) and PDF documents. Audio and video are explicitly out of scope for the current launch.

Where it is supported, media in a span's input or output is stored and treated as part of that span's payload, the same as a tool call or a retrieved document, not a separate lookup.

If your agent runs over voice, what Tessary sees today is whatever text your instrumentation puts in the span, a transcript, a summary, whatever fields you choose to emit, not the raw audio itself. [Instrumentation is what decides what content leaves an agent's traces in the first place](/answers/instrumentation/who-decides-what-content-leaves-an-agents-traces), and that decision is what shapes what a voice agent's trace can show today.
