Audio Processing &
Privacy Architecture.
How recordings are previewed, sent for analysis, and retained by this website.
Audio Preview & Flash Analysis
My Audios uploads WAV recordings to website storage and checks their format. The inspector previews session files in your browser. Run analysis sends the original stereo WAV through this website to flash.vionis.site for Caller CH0 classification. Agent CH1 supplies conversational context.
Real Model Results
Voice Authenticator displays the actual Vionis Flash verdict, confidence, measured features, and processing time. Results can be wrong and do not verify identity. Flash does not perform semantic verification. Requesting a transcript separately sends audio to ElevenLabs; transcripts are not used by Flash.
Client State & Persistent Preferences
Non-sensitive UI preferences (theme mode, navigation rail toggle state, selected sample and tab parameters) are stored in client-side LocalStorage and session cookies. Recordings and their filenames, duration, sample rate, upload date, and channel mapping are retained in website storage when uploaded through My Audios. Flash analysis results remain in session memory and are not saved by this website. The Flash adapter does not log or persist audio. This page does not make retention guarantees about external processing services.
Deterministic Session Teardown
Resetting the inspector or closing the tab ends the active audio preview. Saved recordings remain in My Audios for future use. Use Delete recording there to remove a file from the shared demo library.
