A cozy idle railway game in a strip along the edge of your desktop. Trains keep running while you work, and the town grows.
Who makes these
Marduk Syndicate is an independent software label making small, offline, one-price tools for PC gamers on Windows and SteamOS/Linux.
The rules are the same for every app:
- It does one job, and the store page and this site say plainly what it doesn’t do.
- Nothing is uploaded. Files, photos, clips and your voice stay on your PC.
- One price, no account, no subscription. You buy it on Steam, you own it.
- Windows and SteamOS/Linux are both native builds, not a Windows app running through a compatibility layer.
The guides on this site answer the questions people actually search for, with tests run on the apps themselves, and show how each app solves the problem in one pass.

- A soundboard for Linux and the Steam Deck: Soundpad doesn't run here, so here's one that does Simple Voice Changer
Soundpad is Windows-only (its Steam page lists Windows 7 or newer and nothing else). Simple Voice Changer's Soundboard runs natively on Linux and SteamOS: named boards, a global hotkey per sound, clips mixed into the same virtual mic as your voice, verified on this site's Linux machine.
- A virtual microphone on Linux without the setup: how Simple Voice Changer creates and removes it Simple Voice Changer
What a virtual microphone is on PipeWire or PulseAudio, why it usually means maintaining sound-server configuration by hand, and how Simple Voice Changer creates one automatically as your normal user and removes it on quit, verified on PipeWire 1.6.
- A voice changer for Linux in 2026: native, from Steam, with a soundboard (and no, Voicemod doesn't run here) Simple Voice Changer
Simple Voice Changer is a native Linux voice changer and soundboard sold on Steam: it creates its own PipeWire or PulseAudio virtual microphone with no driver and no root, runs under the Steam Linux Runtime on any current distribution and SteamOS, and was verified on this site's Linux machine.
- A voice changer without a subscription, an account or a server: what 'buy once' actually gets you Simple Voice Changer
How subscription voice changers are sold, without quoting prices, and what changes in practice when the app is bought once on Steam, runs offline and needs no account: no renewals, no lock-outs, no forced redesigns, your files on your PC. With the honest trade-off.
- A Voicemod alternative that runs offline, on Linux, with no subscription Simple Voice Changer
Why people look for a Voicemod alternative (subscriptions, the V3 redesign, log-in outages, more than one soundboard, moving to Linux) and what Simple Voice Changer does about each: neural voices on your CPU, your own RVC models, named soundboards, music under your voice, offline, one price, Windows and Linux.
- How to play music through your mic on Discord, and the two mistakes every tutorial makes Simple Voice Changer
Playing music or sound effects through your mic in Discord, games or streams with Simple Voice Changer: why music routed through a voice changer comes out pitch-shifted, why a music bed breaks voice detection unless it ducks, and how the Music page and Soundboard handle both. Plus copyright and server-rules caveats.
- How voice changers work: pitch, formant, robots, neural voices and what each can't do Simple Voice Changer
What a real-time voice changer actually does to your voice: pitch and formant shifting, vocoders, distortion, echo and reverb, and how neural voice conversion differs. How the audio reaches Discord and games, how much delay each kind adds, and the honest list of what each can't do.
- A game magnifier for KDE Plasma 6 (Wayland): why the built-in zoom isn't enough for reading games, and a lens that is Second Look
On KDE Plasma 6 under Wayland, the built-in Zoom effect magnifies the whole desktop and pixelates at high zoom. Second Look is a lens that enlarges only what's under the pointer, sharpened, with hotkeys and per-game profiles, built for KWin. Steam Deck Desktop Mode included. Not GNOME, not X11.
