Audio C2PA — Frequently Asked Questions

What is C2PA for audio?

C2PA (Coalition for Content Provenance and Authenticity) extends to audio files, embedding tamper-evident metadata that records the audio's origin, editing history, and creator information.

What audio formats are supported?

Our C2PA Audio Checker supports MP3, WAV, FLAC, OGG, AAC, and M4A audio formats up to 50MB.

Can C2PA detect AI-generated audio?

Yes. If audio was created using an AI tool that embeds C2PA metadata (like AI voice generators or music tools), our checker will detect and display this information.

How does audio C2PA analysis work?

Upload an audio file and our tool scans it for embedded C2PA manifests containing provenance data, digital signatures, and content creation history.

Is my uploaded audio stored?

No. Audio files are processed on our server and immediately deleted after analysis. We never store, share, or retain any uploaded files.

Can AI voice clones be detected with C2PA?

C2PA can help identify AI-generated voice content if the creation tool embeds C2PA metadata. However, voice clones made without C2PA-supporting tools won't have this metadata.

What is a C2PA manifest in audio?

A C2PA manifest in audio is embedded metadata containing assertions about the audio's creation, editing tools used, digital signatures, and content provenance chain.

Which audio tools support C2PA?

Audio C2PA support is expanding. Major audio production tools and AI voice platforms are beginning to integrate C2PA for content authenticity.

Can C2PA survive audio compression?

C2PA metadata can be preserved in some audio formats, but heavy compression, re-encoding, or format conversion may strip the metadata.

What is the maximum file size?

The maximum audio file size for C2PA analysis is 50MB. Larger files should be trimmed before uploading.

Is the C2PA Audio Checker free?

Yes, completely free. No signup, no watermarks, no limits on the number of audio files you can check.

What does 'No C2PA Data' mean for audio?

It means the audio file doesn't contain any C2PA content credentials. This could be because it was created before C2PA adoption, the metadata was stripped, or the tool used doesn't support C2PA.

Can podcasts contain C2PA data?

Podcasts can contain C2PA data if the recording and publishing software supports C2PA embedding. This helps verify the podcast's authenticity and origin.

What is digitalSourceType in audio?

digitalSourceType is a C2PA assertion indicating how audio content was created — such as 'trainedAlgorithmicMedia' for AI-generated audio or 'capture' for live recordings.

Does Spotify preserve C2PA metadata?

Major streaming platforms are evaluating C2PA support. As the standard matures, platforms like Spotify may begin preserving and displaying C2PA provenance data.

What is Content Credentials for audio?

Content Credentials is the consumer-facing label for C2PA technology applied to audio, providing listeners with verifiable information about the audio's origin and editing history.

Can music tracks contain C2PA data?

Yes, music tracks can contain C2PA data if the digital audio workstation (DAW) or distribution platform supports C2PA embedding.

How accurate is C2PA audio verification?

C2PA verification is cryptographically secure. If C2PA data is present, the verification is definitive. However, absence of C2PA data doesn't mean the audio is fake.

Can AI text-to-speech be detected?

If the text-to-speech tool embeds C2PA metadata marking the output as AI-generated, our checker will detect it. Tools like ElevenLabs and others are adding this support.

What companies support C2PA for audio?

Adobe, Microsoft, Google, BBC, and others support the C2PA standard. Audio-specific C2PA adoption is growing as concerns about AI-generated audio increase.
