Problem
Remote guest microphone processing doubles with local processing and produces hollow or phasey speech.
Solution
Root Cause / Diagnostic:
When a remote guest applies hardware DSP, software noise suppression, and compression on their local machine, and the studio engineer applies a second chain of dynamic processing, comb filtering and aggressive phase artifacts occur. Cascading dual compressors and equalizers causes severe phase distortion, unnatural frequency notches, and a thin, robotic vocal timbre.
Actionable Fix:
1. Audit and disable all client-side processing on the remote guest's client software: turn off Discord/Zoom/WebRTC noise suppression, echo cancellation, and auto-gain, requesting a raw, unprocessed 48 kHz linear PCM feed.
2. Consolidate audio signal processing exclusively at the studio broadcast console/DAW, managing all high-pass filtering (80 Hz), parametric EQ, and compression from a single master control point.
3. Compare the guest's raw input feed with the processed channel strip in real-time, verifying that the vocal fundamental frequencies (120 Hz to 250 Hz) remain warm, natural, and free of comb filtering notches.
Pro Tip:
Provide incoming remote guests with an automated pre-configured onboarding link (e.g., VDO.Ninja with `&proaudio=1&clean=1`) that automatically bypasses client browser preprocessing and delivers broadcast-grade uncompressed audio.
