Riffline: Music Practice

Your music practice tools, together in RIFFLINE.
Practice the difficult part at your own pace.

From guitar riffs and fast solos to vocal and band practice: open your own audio, adjust the key and tempo, and repeat the part you want to learn. Player, metronome, tuner and library are in one app.

Change pitch and tempo while playing
• Shift the key from -12 to +12 semitones to suit your practice.
• Adjust playback speed from 50% to 150% while preserving pitch. Pitch and speed can be set independently.
• Find your practice tempo with automatic BPM estimation and tap tempo. Estimates may vary with the track.

Focus on the part that matters
• Move the A and B handles on the waveform to repeat a section.
• Pinch to zoom, swipe with one finger to pan, or tap to seek.
• Enter times directly for precise loop boundaries.

A metronome for your rhythm
• Set 30–360 BPM in 0.5 BPM steps.
• Choose meters such as 4/4, 5/4 and 6/8, plus beat subdivisions.
• Pick click, wood, rim, bell or digital sounds.
• Turn individual beats on or off and set a separate metronome volume. The metronome runs independently of the player.

Tune in the same app
• Read note names, frequency and cents with the chromatic tuner.
• Choose Standard E, Half-step down, Drop D, D Standard or Drop C.
• Adjust the A4 reference from 430 to 450 Hz.
• Six-string simultaneous tuning analysis is available in beta. If harmonics overlap or a reading is uncertain, check one string at a time.

Keep your practice setup
• Save each track's pitch, tempo and loop settings, along with named presets.
• Export the entire track or an A–B section as a 16-bit WAV with your pitch and tempo settings.


Four looks for your practice
• Daylight: a bright, calm workspace.
• Original: dark tones with bold accents.
• Mono: a hand-drawn monochrome style.
• Neon: vivid neon colors.
• Switch in Library under SKIN. All four skins share the same features.

Before you start
• WAV, MP3, FLAC, AIFF and other formats depend on codecs supported by your device. Import supports mono or stereo tracks up to 50 MiB and 10 minutes per file.
• The tuner requires microphone permission.
• Playback and practice tools stop when you leave the app or lock the screen.
• The library uses on-device storage. Keep original audio backed up before clearing app data or uninstalling.
• Export large WAV files in shorter A–B sections.
• Music files are not included. Import audio you have the right to use.
