Hey everyone!
I've been working on a project for a while and finally feel like
it's ready to share. It's called Shockwave — an all-in-one e-stim
signal generator, funscript player, and remote control app for
Linux.
Why I built it: I love what's out there — Restim is fantastic for
tri-phase, Howl has great audio support, MultiFunPlayer does
amazing things with device sync. But I'm on Linux, and I wanted
something native that brought everything together in one place
without switching between apps or dealing with compatibility
layers.
So I built the tool I wished existed.

What It Does
Signal Generation — Full tri-phase with 24 animated motion
patterns, basic waveforms (sine, square, triangle, saw), and
pulse patterns. Real-time oscilloscope display.
Funscript Playback — Here's something I'm pretty happy with:
velocity-based intensity. Instead of mapping position directly to
output, it maps movement to intensity. Fast motion = strong
signal, stationary = silence. For e-stim this feels way more
natural to me since sensation comes from the change, not the
position. Your mileage may vary but I love how it feels.
Batch Funscript Conversion — Select a whole directory, convert
everything to tri-phase patterns in one go. Generates prostate
patterns, motion axes, all the good stuff. Great for processing a
big collection.
Media Player Sync — Connects to VLC, MPC-HC, HereSphere (VR), and
Emby. Play a funscript and it automatically searches your video
folders to find and play the matching video. Fuzzy name matching
handles inconsistent filenames. Adjustable latency for
fine-tuning sync.
Remote Control — This is my favorite feature honestly. Full
mobile web interface — open it on your phone, enter a PIN, and
you have complete control. Transport, signal parameters, library
browsing, edging sessions. Emergency stop always visible. No more
awkward trips back to the keyboard.
14 Edging Modes — Mix of automatic (Tease & Deny, Random Torture,
Wave Interference, Breathing Edge) and interactive (Ride the
Edge, Manual Throttle, Edge Training). Signal when you're close,
the system responds. Session stats tracking.
Audio Library — Import WAV/FLAC/OGG/MP3, rate tracks, create
playlists, favorites. Basic but solid.
Safety Features — DC blocking, amplitude limiting, fade-in
protection, rate limiting. Spacebar = instant silence. The
waveform shows actual output.

What Makes It Different
The main thing for me was having everything integrated. Funscript
conversion, playback, video sync, signal generation, remote
control, library management — all in one window, all working
together natively on Linux.
The velocity-based funscript playback is also something I haven't
seen elsewhere and it makes a real difference for how scripts
feel (at least to me).
And the phone remote is just chef's kiss for convenience.

This has been a fun project and it's become my daily driver.
Figured I'd share in case others find it useful too. Happy to
hear feedback, bug reports, feature ideas — whatever.
Enjoy!
