ErrorTone

Play an audio alert when your terminal commands produce errors. No configuration required — just install and start hearing alerts.

Features

Automatic error detection: Monitors all integrated terminals for error patterns
10 built-in patterns: error, Error, ERROR, Exception, Traceback, Failed, Segmentation fault, panic:, npm ERR!, ModuleNotFoundError
Custom audio file: Use your own .mp3, .wav, or .ogg alert sound
Custom patterns: Add your own error detection patterns (plain text or regex)
Smart debouncing: Prevents audio spam when errors repeat rapidly
Volume control: Adjust alert volume from 0.0 (muted) to 1.0 (full)
Cross-platform: Works on macOS, Linux, and Windows

macOS: Uses afplay for audio playback with native volume control
Linux: Uses paplay (PulseAudio) or aplay (ALSA) — install PulseAudio for volume support
Windows: Uses PowerShell System.Media.SoundPlayer
Remote/SSH: Shell integration may be limited — extension degrades silently
WSL: Works with PulseAudio audio backend configured
