I’m currently trying to set up a homebrew cassette tape storage format, but trying to use existing tech where possible. I was excited to see that minimodem already exists for converting an audio stream to a byte stream, and is even available in termux for android, so I could decode cassettes with my phone! However, I’d like some sort of higher-level tool to encode and decode “packets” or “slices” so that I can add error correction. I’m sure this sort of thing must exist for amature radio purposes.
I could write a script that cuts a file into slices, with checksums and redundancy for each slice, and then pads them with null bytes so I can isolate each frame when decoding. What I want is to find out if that’s already been done. I’ve heard of AX.25 packets but I can’t find a tool that does that with stdio.
Interesting. Is that some new project?
No, but to learn bring computing to 2024 and to pad my github I’m currently working on a modern replacement written in React that can also use Electron on the desktop. It’s pretty light at around 150mb. I don’t have plans to natively port it to Linux, but it’ll work in Windows Linux and MacOS with a little tweaking.
I do have plans to release the Docker image I’ve used for testing later this year along with a Snap and Flatpak so I guess it will natively work on Ubuntu.
Oh, and longterm goals are to have an Android and iPhone port. I have an ad provider set up so I can offer the mobile apps for free (gotta hustle) but I’ll have a patreon and kofi set up by then for donations and a mostly ad-free version that aggregates usage info of your device and apps but doesn’t give away any personally-identifiable details if you opt-out.
I do almost nightly coding streams on Twitch and Youtube but I blur out the code itself because I don’t want anyone borrowing my idea and implementation.
You can find me on Insta, TikTok, Facebook and I’ll have links to my X (formally known as Twitter), Telegram, Discord, Riot, and Mastodon accts. I also have curated some playlists on Apple Music, Spotify, Tidal, and Amazon Music that include some chillwave tracks as well as some binaural beats, white noise, pink noise, and brown noise (to name a few).
I also have an affiliate link for a microdose provider that gives me a cut everytime you make a purchase which helps me out.
