After recording the last episode via Transmits, I mentioned that I needed to test recording on playback on mobile, specifically Mobile Safari (since I am an iPhone user), and Chrome on Android. My goal for Transmits is that I can launch the initial version as a progressive web app (PWA), so it’s crucial for it to work when added to the home screen on either iOS or Android devices.

Well, in classic fashion, once I went to test the app on mobile devices, it totally failed in Mobile Safari, and regular Safari for that matter. It turns out that Safari only supports saving files via the FileSystemSyncAccessHandle, which only works within the context of a Web Worker. So, I rolled up my sleeves and started refactoring the app to include a web worker–surprisingly the first one I have written!–and wire up the file saving to use it. Low and behold, this week’s episode was recorded on my iPhone, via Transmits running as a PWA!

Next up, I am working on a spike to get speech to text working for transcription running locally via a Web Assembly (WASM) wrapped version of OpenAI’s Whisper model. Once that is working, then will come defining the data models and start working on building out the cloud sync support. Not gonna lie, I am getting pretty stoked on this app so far, and I hope you will too!
