💖 MHA(1) — the openMHA server, bestie edition 💖

okay so this is the manual for mha, aka the openMHA server — as in the Open Master Hearing Aid framework. It lives in the User Commands corner of your man pages and it's literally the main character of the whole openMHA situation. ✨

🌸 NAME 🌸

mha — the openMHA server (Open Master Hearing Aid). That's it, that's the name, and honestly? Iconic.

🎀 SYNOPSIS 🎀

mha [OPTION]...  [COMMAND]...

🦋 DESCRIPTION 🦋

So mha is the main server component of the Open Master Hearing Aid (openMHA) framework. She's the backbone, the moment, the whole vibe. 🫶

She hands you a configurable runtime environment for audio signal processing — which is a fancy way of saying this is the stuff people use for hearing aid research and development. Very science, very slay.

The server can be controlled over network connections or interactively (choose your own adventure 💅), and she supports loading and configuring processing chains that are built out of openMHA plugins. Mix, match, stack 'em up. No cap.

✨ OPTIONS ✨

Every flag, every letter, nothing skipped, fr fr:

  • -q, --quiet — shush era. Suppress all output. 🔇
  • -p portno, --port=portno — set the server port number. The default is 33337. 📞
  • -a port, --announce=port — announces the process ID and the port number to 127.0.0.1:port. Like "hey localhost, it's me, here's my PID and my port" 💌
  • --interactive — starts in interactive mode. Come talk to her directly. 🗣️
  • -i str, --interface=str — sets the server interface to str.
  • -d, --daemon — daemon mode: she restarts automatically after exit. Immortal queen behavior. 👑 (she just keeps coming back)
  • -o str, --ok-ack=str — sets the acknowledgement string used for successful operations. Your little "yay it worked" phrase. ✅
  • -f str, --fail-ack=str — sets the acknowledgement string used for failed operations. Your little "uh oh" phrase. 😭
  • --log=logfile — turns on logging, writing to logfile. Receipts, kept. 🧾
  • -h, --help — displays a help screen and exits. The "just tell me what to do" button. 🙈

🌈 COMMANDS 🌈

Commands can be handed over on the command line or typed in interactively, whenever you're running in interactive mode. Either way, same energy. ✨

These commands are the ones you use to configure and control the openMHA processing pipeline. That's the whole point of them, iykyk. 💜

🍓 EXIT STATUS 🍓

  • 0 — successful execution. we ate. 🎉
  • non-zero — an error happened during startup or operation. not the vibe. 💀
