What is Audio OSINT ?

Audio OSINT is the process of finding valuable information from sound recordings and related material. It is a part of OSINT, which uses publicly available data to gain insights. Audio sources for OSINT can include official government press conferences, informal interviews on social media, podcasts, YouTube videos, police radio scanners, and call-in radio shows. These sources can provide valuable insights and help investigators make informed decisions.

Audio data can also be the first source of information for an event or activity, giving early indicators or alerts.

Identify Relevant Audio Sources: Monitor radio shows, podcasts, YouTube channels, and any other platform where audio data might be shared.

Record and Archive:
Save audio recordings into a repository for future reference.

Transcribe and Translate:
Convert audio recordings into text for easier searching. Use speech-to-text technology or manually transcribe. For foreign languages, translation is also necessary.

Analyze and Extract Intelligence: Read and interpret transcribed texts, looking for patterns, common themes, and other relevant data points.

Cross-Reference with Other OSINT Sources: Validate findings and build a more comprehensive understanding of the situation by cross-referencing with other forms of OSINT.
