Music Speed Changer for Android

App snapshot

Music Speed Changer is a freemium audio editor for mobile devices that gives precise control over tempo and tuning. It’s designed for people who want to slow down, speed up, or retune tracks for practice, transcription, remixing, or general listening. The engine uses high-quality time-stretching and pitch-shifting algorithms to maintain audio fidelity while you experiment.

Core editing capabilities

• Independent control of tempo and pitch so you can change speed without altering key, or shift pitch without changing tempo.
• Time stretching that ranges from 15% to 500% of the original playback rate for extreme slow-downs or fast previews.
• Pitch adjustment spanning up to ±24 semitones for dramatic retuning or subtle transposition.
• The option to alter speed and pitch at the same time for advanced manipulation.

Looping and practice features

• Seamless looping of selected sections to facilitate focused practice, transcription, or detailed listening.
• Instant auditioning of looped segments so you can repeatedly hear the same passage without interruption.

Effects, mixing and vocal tools

• Built-in audio effects such as echo, flanger, and reverb to shape the sound.
• A vocal reduction feature that lowers lead vocals for karaoke-style playback.
• An 8-band graphic equalizer for frequency-based tone adjustments.

Interface and performance highlights

• Modern material-style interface with waveform displays to help with precise seeking and editing.
• An integrated audio recorder so you can capture performances or ideas directly in the app.
• Real-time playback and on-the-fly adjustments that don’t require full decoding, resulting in smooth, low-latency edits.
