What is MicUp?

MicUp is a real-time microphone processing app for Android. It captures your mic input, runs it through a DSP effects chain, and routes the processed audio to a virtual microphone — so every app on your phone (Discord, Teams, Zoom, WhatsApp, etc.) hears the cleaned-up, processed version of your voice.

No PC required. No monthly subscription.

Features

• Built-in DSP chain — Noise Gate, 10-band EQ, Compressor, Reverb, Pitch Shifter
• Plugin support — Load LV2, CLAP, and VST3 native plugins (.so, .clap, .lv2)
• Open plugin files — Tap a plugin file in your file manager to import it directly
• Monitor toggle — Hear your processed audio through headphones, or silence it while still routing to other apps
• Shizuku support — ADB-level ALSA loopback routing without full root
• Three virtual mic tiers — VoIP stream (no root), Shizuku (ADB), or Magisk (full root)
• Live VU meters — Input, output, and gain reduction metering
• Preset system — Save and load your effect configurations
• Built-in crash reporter — Crash logs auto-shared for easy bug reporting

License

MIT License — see LICENSE

This release focuses on stability and audio quality — especially for Android 14 and Shizuku users.

Fixed

• Crash on Android 14+ when the microphone service started while the app wasn't in the foreground
• Shizuku could fail to be detected if it wasn't ready at app launch (now auto-upgrades once available)
• Removed a permission misconfiguration that could block Shizuku's ADB-level routing
• Runaway restart loop on audio stream errors (now capped with backoff)
• Battery optimization prompt no longer nags on every launch once exempted

Improved

• Rewrote the audio monitor pipeline (16-bit → 32-bit float, dedicated worker thread) for smoother, glitch-free monitoring
• Manually switch between VoIP / Software Loopback / Shizuku / Root tiers in Settings, with clear reasons when a tier isn't available
• Pick your monitor output device (headset, speaker, earpiece, etc.) — now remembered across restarts
• "Hear yourself" monitor toggle now persists between sessions
