PartPerfect supports MP3, M4A, WAV, AAC, AIFF, and CAF files. Tap the "+" button in the Library and choose Import Learning Track to open your device's file picker.
Yes — tap the "+" button in the Library and choose Import Sheet Music. PartPerfect accepts PDF files. They appear in the Sheet Music view with a full-screen viewer that supports scrolling and pinch-to-zoom.
The track title is pulled from the audio file's metadata (ID3 tags). If there's no metadata, the filename is used instead. To fix the title, you'll need to update the metadata or rename the file before importing.
PartPerfect includes two built-in tracks — an introduction track called PartPerfect Overview and a Bluetooth Synch reference track for calibrating Bluetooth latency. Beyond those, you import your own learning tracks from your chorus, choir, or barbershop group.
Use the Balance slider on the Player tab. Many learning tracks have your part panned to one channel (left or right) and the other parts on the opposite channel. Slide the balance toward the channel that has your part to hear it more prominently, or slide the other way to hear just the other parts.
Go to the Settings tab and turn on Play as Mono. This sends the channel selected by the Balance slider to both ears instead of keeping it in its original stereo position.
Yes. Tap the turtle icon on the transport controls to cycle through three speeds: 1.0x (normal), 0.75x, and 0.5x. The pitch stays the same — only the tempo changes.
On the Player tab, drag the crop brackets on the waveform inward to mark the section you want to practise. Then tap the loop toggle button on the transport controls. Playback will repeat just that cropped section until you stop it.
The Record tab needs exclusive control of the audio system for recording, so it stops any track that's currently playing. Your learning track will keep playing if you switch to the Library, Pitch, or Settings tabs instead.
Headphones aren't strictly required, but they're strongly recommended when recording with a learning track. Without them, the learning track audio bleeds into the microphone, which affects your recording quality and pitch analysis accuracy. Both wired and Bluetooth headphones work.
PartPerfect always records from the device microphone, not from a headphone microphone. This gives you better audio quality for singing.
PartPerfect automatically compensates for audio latency, but Bluetooth headphones can introduce extra delay. Go to the Settings tab and adjust the Recording Sync Adjust slider (0–500 ms in 5 ms steps) until the alignment sounds right. Changes take effect immediately on your existing recording — no need to re-record.
Load the Bluetooth Synch track from the Library, record yourself with your Bluetooth headphones connected, then play back the recording. If the timing sounds off, adjust the Recording Sync Adjust slider in Settings until your recording lines up with the track. You'll hear the change in real time.
Go to the Settings tab and turn on Remove Low Rumble. This applies a filter that removes frequencies below 80 Hz, cleaning up room noise, air conditioning hum, and other low-frequency interference.
Turn on Auto-Normalize Volume in the Settings tab. This automatically adjusts your recording to a consistent volume level after you stop recording.
Yes. Tap the Solo Record button (the microphone icon in the Library header) to go straight to the Record tab in solo mode. You can also navigate to the Record tab without loading a track. In solo mode, the Balance slider is hidden and pitch comparison is not available since there's no reference track.
If you try to load a new track from the Library while you have a recording, the app will ask whether you want to discard the recording and load the new track, or keep the recording and go to the Record tab instead.
After recording with a learning track, tap the Check Pitch button on the Record tab. You'll be asked to choose which channel of the learning track contains the vocal part you were singing (Left, Right, or Centre), set a tolerance level, and then tap Analyze.
Standard tolerance is ±25 cents — a good choice for general practice. Strict tolerance is ±10 cents for a tighter evaluation. A cent is 1/100th of a semitone, so Standard gives you a reasonable margin while Strict holds you to a very precise standard.
Green bars mean you were on pitch (within the selected tolerance). Red bars mean you were off pitch. Grey bars indicate silence, breaths, or sections where pitch couldn't be detected.
It shows how much of your singing was within the selected tolerance. The percentage is colour-coded: green for 80% or above, yellow for 50–79%, and red for below 50%.
The Check Pitch button may be greyed out if there's nothing to analyse yet (for example, you haven't made a recording), or if you're currently in the middle of a recording. Once you've stopped recording and have a result to review, the button should become active.
PartPerfect's pitch analysis uses a signed average approach, which is vibrato-friendly. If you oscillate evenly above and below the target note (as singers naturally do with vibrato), those deviations cancel out and the bar shows green. The analysis looks at the average tendency, not individual wobbles.
This depends on how your learning track was mixed. Typically, your part is panned to one side (left or right) and the other parts to the opposite side. If you're not sure, try using the Balance slider on the Player tab first — slide it fully left, then fully right, and listen for which side has the vocal line you're singing. That's the channel to select when running pitch analysis.
Go to the Pitch tab. The pitch pipe displays 12 note segments in a circular layout. In the default Non-sticky mode, press and hold a segment to play the note, and release to stop. Switch to Sticky mode to tap notes on and off — you can even tap multiple notes to build a chord.
Tap one of the four octave buttons (2, 3, 4, or 5) below the pitch pipe to change the octave for all notes.
Tap the Clear All button. It's active whenever one or more notes are sounding.
Yes, as long as you have the app for that cloud service installed on your device. The share sheet will include those services as sharing options.
Tap the "+" button in the Library and choose New Folder. The folder is created in whichever view you're currently on — Tracks or Sheet Music.
Long-press on the item and drag it onto the folder.
The items inside the folder are not deleted — they move back to the top level of the Library.
Yes. Breadcrumb navigation at the top of the Library (e.g., Home > Vocal Exercises > Warm-ups) helps you find your way around nested folders.
All your tracks, sheet music, and recordings are stored locally on your device. PartPerfect does not upload your audio or recordings to any server.
You can share files manually to a cloud service like Dropbox, Google Drive, or iCloud Drive using the share function. There is no automatic cloud backup built into the app.
No. PartPerfect does not collect, store, or transmit any of your personal data. The app has no user accounts, no server-side storage, and no data collection of any kind. Everything you do in the app stays entirely on your device. See the full privacy policy for details.
No. All audio processing — including recording, playback, pitch analysis, and mixing — happens locally on your device. Your recordings are never uploaded to a server or processed in the cloud. They remain on your device unless you choose to share them yourself.
No. PartPerfect does not require a login, account creation, or any form of registration. You can start using the app immediately after downloading it — no email address, username, or password needed.
No. PartPerfect does not include any analytics frameworks, tracking pixels, or usage telemetry. We have no way of knowing how or when you use the app, and that's by design.
No. PartPerfect works entirely offline. All features — importing tracks, recording, pitch analysis, the pitch pipe, and sharing — function without an internet connection. The only time you need connectivity is when downloading the app itself or sharing files to an online service.
No. PartPerfect contains no advertising and does not share any data with third parties. There are no ad networks, no sponsored content, and no data sold or shared with advertisers.
Go to the Settings tab and find the Enharmonic Notes option under Display. Choose Sharps to see notes like C♯, D♯, F♯ or Flats to see D♭, E♭, G♭. This affects the note display in the Player and pitch analysis results. The Pitch Pipe always shows both sharps and flats on each segment regardless of this setting.
Make sure PartPerfect has permission to access your microphone. On iOS, go to your device's Settings > Privacy & Security > Microphone and check that PartPerfect is enabled. On Android, go to Settings > Apps > PartPerfect > Permissions and make sure the Microphone permission is set to Allow.
Some tracks with complex harmonics may sound slightly different at reduced speeds. This is normal — the time-stretching algorithm preserves the pitch but may alter the timbre slightly, especially at 0.5x.
Try using the search bar at the top of the Library. Search results span all folders, so you don't need to know which folder it's in.
This happens when you try to load a new track or start a new recording while an existing recording is still in memory. You'll always be asked to confirm before anything is discarded — nothing is deleted without your permission.
Bluetooth audio introduces extra latency that can cause your recording to sound slightly ahead of or behind the learning track during playback. PartPerfect compensates for this automatically, but you may need to fine-tune it. Go to the Settings tab and adjust the Recording Sync Adjust slider until the alignment sounds right — changes apply immediately to your existing recording, so you don't need to re-record. To help with calibration, load the built-in Bluetooth Synch track from the Library, make a recording with your Bluetooth headphones connected, then play it back and adjust the slider until everything lines up.
