Music Speed Changer ▶▶▶

Music Speed Changer lets you adjust tempo and pitch in real time without affecting each other, with time-stretch and pitch-shift modes. You can loop sections, set AB points, and bookmark markers while you practice, making it ideal for musicians, students, and language learners who need to slow down, transpose, or highlight tricky parts.

It doubles as a full music player with playlists, queue, EQ (8-band), balance, preamp, and effects like reverb and delay. Pro adds formant shift and AI-driven key/BPM detection for smarter tone and easier creation; you can save edits to a new M4A and export.
