Audacity 4 has no vocal remover effect, so here are the three routes that work: the built-in center-cancel with Invert, the free OpenVINO Music Separation effect in Audacity 3, and a stem-separation plugin from MuseHub — with the exact menus, one comparison table and an honest account of what each can and cannot do.
Speed, tempo and pitch are three different jobs in Audacity. This guide covers each one in Audacity 4 (the clock handles, the pitch and speed dialog, BPM math, reset and render), fixing a tape or record that ran at the wrong speed, slowing a song down to practise, and the Audacity 3 routes.
Noise reduction leaves some sounds alone. How to lower breaths with Clip gain, fix mouth clicks with Click removal and Repair, take out squeaks, coughs and chair noise, and what really helps against room echo in Audacity 4.
Why a pitch change alone does not disguise a voice, how Audacity 4 splits voice effects between the Effect menu and realtime plugins, starting settings for robot, malfunctioning android, demon, FM radio and telephone voices, a free plugin chain you can save, and male-to-female changes.
