Music Speed Changer

Slow down music without losing quality with Music Speed Changer, the professional audio editing app that lets you adjust tempo, pitch, and playback speed independently or together — all in real time.

Whether you're a musician practicing a difficult passage, learning to play an instrument in a different tuning, or simply wanting to experience your favorite tracks at a new speed, this app transforms how you interact with audio. Change the speed from 15% to 500% of the original tempo to match any practice pace or listening preference. Shift the pitch up or down across 24 semi-tones with fractional adjustments, giving you complete creative control without compromising audio quality. The professional-grade time stretching and pitch shift engine ensures your music sounds natural and clear at any speed or key.

Practice like never before with the advanced music looper. Capture sections of a song using seamless AB repeat playback, then loop them endlessly while you master tricky parts. Move between measures with a single tap to isolate exactly what you need to practice. Reverse any track to decode hidden messages or learn passages backwards and forwards. The waveform view gives you precise, visual control for hitting the exact moments you want to work with.

Take your audio creation further with professional tools built right in. An 8-band graphic equalizer with preamp and balance control lets you shape the sound to your preference. Apply effects like echo, flanger, and reverb, or reduce vocals for karaoke-style practice. Analyze any track to instantly see its BPM and musical key. Advanced audio separation features split vocals, drums, bass, and other instruments in any song, giving you isolated stems to work with — perfect for remixing or focused practice.

Save your edited audio as MP3, FLAC, or WAV files to share with friends or use in other players. Export the whole track or just your looped section to create unique ringtones or shareable creations. The built-in audio recorder captures new material directly within the app. Bookmark important positions with markers for quick navigation during long sessions.

Music Speed Changer works with virtually all audio formats and delivers instant playback with zero wait time for decoding. Its clean material design interface and light or dark theme options make it a pleasure to use for hours of practice, whether you're slowing down audiobooks, creating nightcore remixes, or pushing your musical skills to the next level.
