Make a karaoke backing track
Open Vocal Remover and choose a stereo song. Choose Fast AI and preview 10 seconds. Quality AI provides a slower alternative for difficult mixes. Listen to the instrumental before processing the full recording. Complex mixes may still contain vocal traces or artifacts. Basic stereo mode is faster, but can also reduce centered instruments. Open Karaoke Studio with the result and use headphones while recording.
Cut a ringtone with smooth edges
Open Audio Cutter, enter the start and end times in seconds, then add a short fade. Listen to the exported WAV to check the opening and ending. Volume & Fades gives separate fade-in and fade-out controls.
Practice a difficult phrase
Choose Practice Room, mark the phrase, and slow the playback. Loop it while practising your voice or instrument. Use tap tempo to check the beat and Live Tuner for one steady note at a time.
