Audio Search

Find audio by description or sample.

Status: Available by request

Search for matching moments in your recordings. Audio Search runs on your computer. Audio, queries, and the search index stay on disk; nothing is uploaded.

Spectrogram of a recording. Time runs left to right and frequency bottom to top; warmer colors mark louder frequencies, including a run of regular pulses at the start.

For archives and sound libraries.

Find a passage in a sensitive recording or a sound in a professional collection without uploading either library.

Private archive search

For recordings that need to stay on your computer, including investigations and internal voice archives.

  • Query by sample or natural language without leaving the machine
  • Moment-level hits inside long recordings
  • Collections and CSV/JSON export for case or matter files

Audio professionals

Search sound effects, field recordings, production sound, podcasts, and radio archives locally.

  • Trim a sample, find similar passages, and listen to compare results
  • Watched folders with chunk windows and overlap you control
  • History, pinned searches, Favorites, and export into your pipeline

Search audio the way you search documents.

Organize libraries, watch folders for new files, and compare results at specific moments in a recording.

Text to audio

Describe what you need in natural language and land on timed moments inside long files.

Audio to audio

Drop a sample—or a trimmed region—and find similar passages across your indexed libraries.

A local search index

The model turns audio and text into numerical representations for matching. This processing runs on your device, with optional GPU acceleration.

Libraries & watch folders

Keep the index current as files appear. Choose the length and overlap of audio segments to search.

Compare, collect, and export

Compare hits, pin favorites into project bins, and export CSV or JSON when work leaves the app.

Command-line tools

Automate indexing and search for ops pipelines that prefer a terminal.

Where your data goes.

The embedding model downloads once. After that, indexing and search run locally. Your audio, text queries, embeddings, and results stay on disk. No cloud embedding service receives them.

  • Chunked indexing with temporal grouping of hits
  • Similarity ranking to find candidate matches for review
  • Index backup and restore
  • Built for private archives and professional sound libraries

Use it to find recordings worth listening to. A similarity score is not proof of what was said or who said it. Review the source audio before drawing conclusions.

The same local-embedding approach is the retrieval half of the private RAG systems we build.
