AudioTweak vs Loopdrill

AudioTweak is an advanced audio player that helps musicians learn, transcribe, and practice songs. With AudioTweak, you can slow down fast passages, loop and save tricky sections, or shift the pitch into a key that fits your voice or instrument. Whether you're learning a solo, arranging a new part, or trying to hear a hidden bassline, AudioTweak gives you the tools to uncover every detail. You can isolate instruments with EQ, adjust tempo without losing sound quality, and even export your loops to keep practicing anywhere. AudioTweak makes practicing music smarter, clearer, and more enjoyable. AUDIO SPEED CHANGER Slow down tricky parts to practice at your own pace, or speed up exercises to build skill—all without affecting sound quality. PITCH CHANGER Adjust pitch to play your music in any key, match your instrument, or fit your voice. Explore alternate keys while transcribing or arranging. AUDIO LOOPER Repeat and focus on specific sections until you master them. Whether it's a tricky solo or a chord change, looping makes it easy to practice the hard parts as many times as you need. Save a loop with a name and jump straight back to it next time you open the song — the verse, the chorus, and that one awkward bar, always a tap away. COUNT-IN METRONOME Start every practice session in the pocket. The built-in count-in metronome gives you a rhythmic lead-in before playback begins, so you're always ready to play along from the first beat. AUDIO ISOLATION Use the 10-band EQ to cut out what's not important, and the stereo pan to shift focus between left and right channels. Perfect for isolating guitars, vocals, or other parts that sit to one side of the mix.

Loopdrill is a music practice player for anyone who learns songs by ear. Bring in a track from Files or Apple Music, slow it down without changing the key, mark the passage you are working on, and loop it until it sits under your fingers. Core playback tools are free. There are no ads and no subscription. SLOW DOWN WITHOUT CHANGING THE KEY Play anywhere from 25% to 200% speed while the pitch stays exactly where it was. Slow a solo down to hear every note, then bring it back up step by step. LOOP THE PART YOU ARE PRACTISING Set A and B on the waveform and the section repeats until you stop it. Drag either handle to adjust the range. Long-press a handle or the playhead to move it at one-tenth speed with a magnified view, so a loop can start exactly on the downbeat. SEE THE SONG The full waveform shows the shape of the track. Tap to jump, drag to scrub, and use bookmarks to mark verse, chorus, bridge and solo so you can get back to them instantly. TRANSPOSE IMPORTED FILES Shift the pitch from -12 to +12 semitones to match your tuning, a capo position or a more comfortable vocal range. A 10-band equalizer with presets such as Bass Boost and Vocal helps you bring the part you are copying to the front. APPLE MUSIC AND YOUR OWN FILES Play songs from your Apple Music library, or import MP3, AAC, WAV, AIFF and M4A files from the Files app. Speed control, loops and bookmarks work with both. Pitch shifting and EQ apply to imported files; Apple Music playback does not allow these two controls. IPHONE, IPAD AND MAC On iPad the library and player sit side by side. On Mac you get keyboard shortcuts for play, seek, loop and lyrics, and file import from Finder. One download covers all three, and the Apple Watch companion controls playback from your wrist. LYRICS PRACTICE PRO (OPTIONAL ONE-TIME PURCHASE) Follow timed lyrics, hold to select consecutive lines and loop a passage, and edit timestamps or the sync offset. Import multiple audio files or folders with matching LRC files. Try all Pro tools for 7 days using your own audio and LRC files that you have permission to use. Start the trial explicitly; there is no subscription or automatic payment. Your audio, lyrics and edits remain after expiry. Continue with an optional one-time Pro purchase at the displayed local price, or restore an existing purchase with the same Apple Account. Restoring does not restart the trial. Pro and trial availability depend on your App Store region. Pro includes practice tools, not a lyrics catalog or AI transcription.
