I wrote Trunk Recorder because I was curious about what my local fire station was up to and I put together the original version of OpenMHz because I figured other people might want to listen to the recordings too.
The latest version of this site makes it easy for other people running Trunk Recorder to share their recordings. I am hoping that making it easier to listen to what our local fire, police and EMS have to go through everyday will lead to a greater appreciation for all the work they do, which goes largely unseen.
The audio from each system is archived for 30 days, so you can go back and listen to events you may have missed.

Transcription of calls from trunk-recorder using OpenAI Whisper.
- transcribe.sh runs from trunk-recorder which makes a POST request to the API, passing along the call WAV and JSON
- API creates a new task to transcribe the call and adds it to a queue (in RabbitMQ)
- Worker(s) (running on a machine with a GPU) picks up the task from the queue and executes it, transcribing audio
- As part of the task, worker makes an API call to Meilisearch to add the transcribed call to the search index
- If notifications are configured, as part of the task the worker will send appropriate notifications
If you're using OpenAI Whisper, you can use a local GPU to accelerate computations.
An online store selling recordings of the weird and offbeat, from Terence McKenna to John Lilly to Faustin Bray.
An archive of recordings from the early days of phone phreaking- stuff like conversations recorded off of bridges, tone sequences, war stories, stuff like that.
An archive of recorded messages and error tones from United States telephony networks. Available for online listening or free download.
A group of dedicated gamers record some of their sessions of play and publish them as podcasts for the rest of us to listen to. If you're not sure if you'll like a game, or if you think you're not running something correctly, see if they've run a session or two of your game and see how they did it.
An archive of pirate radio broadcasts from the late 1990's at archive.org. You can download them for free or listen to them online. The quality of some of the recordings is kind of poor (it is pirate radio, after all) but occasionally you'll come across a gem in the rough.
Archive of shortwave radio recordings to download.
