TuneLab Piano Tuner vs BDAA

This app is for professional piano technicians. This is a professional tool that produces a custom piano tuning for any piano. It is part of the TuneLab line of piano tuning programs for smartphones, tablet computers and laptops that piano technicians have been using since 2001. Notable features: * Measures and uses inharmonicity of the piano to construct a custom tuning. * Provides an over-pull mode for more accurate pitch-raises. * Can store hundreds of tuning files for individual pianos. * Tuning files can be stored locally and in the Cloud on Dropbox. * Provides many historical temperaments for period music. * Switches notes automatically when you play the next note. * Provides a strobe-like Phase Display for fine-tuning. * Provides a versatile frequency spectrum display. TuneLab lets you customize a tuning by sampling the inharmonicity for a few notes of the particular piano. You can choose the kind of tuning stretch you want by specifying different intervals for the bass, the treble, and the mid-range of the scale. These intervals can be octaves, 12ths, double octaves, etc. Good defaults are in place if you are not sure which settings you prefer. After a custom tuning has been created from inharmonicity measurements you can store this tuning by name. The next time you need to tune that piano, or one very much like it, you simply load that same tuning file and start tuning. There is essentially no limit to the number of tuning files that you can store. TuneLab comes with some sample tuning files and an "Average" tuning file so you can start tuning right away without bothering to measure inharmonicity. TuneLab covers the normal piano range from A0 to C8 (88 notes). The automatic note-switching feature makes it possible to enjoy hands-free operation. There is also easy one-touch manual note switching. TuneLab has two different displays that are visible at the same time. One is the strobe-like Phase Display. This is a band where black squares move left or right depending on whether the note is sharp or flat. Tune the note to make the pattern stop moving. The other is the Spectrum Display. This is a graph of the frequency spectrum around the desired note that shows a peak in the audio frequency spectrum for every pitch present in the sound. The object in using this display is to tune the note until the peak in the graph is positioned at a central red line. The Spectrum Display makes it possible to do a rough pitch-raise without mutes since each string of a unison produces its own peak in the graph. Having both the Phase Display and the Spectrum Display visible at the same time gives you a more complete picture of the tuning than any single spinner-type or needle-type display. The Phase Display displays a selected partial at each note, but it can optionally display the tuning of up to four different partials at once in multi-partial mode.

BDAA is the companion app for the BDAA Convention — the annual gathering of musicians who play domra, balalaika, bayan, and the rest of the Slavic folk-instrument family. The community is multicultural: Russian, Ukrainian, Belarusian, and other traditions, all in one room. Sign in with the email you registered with, and the app shows you what you came for: — THE SCHEDULE. Every rehearsal, masterclass, concert, and meal in one place. Updates as the program evolves. Bookmark sessions and the app notifies you when their time or room changes. — YOUR PART. Pick your instrument and the app shows the right sheet music for every piece. Open the score in full screen, pinch to zoom, flip pages with a swipe. New revisions arrive without you doing anything. — REFERENCE AUDIO. Most pieces include a reference recording so you can practice along with how the conductor wants the piece to feel. — ANNOUNCEMENTS. Quick messages from the organizers — "rehearsal moved to room B", "bus leaves at 9", "send your photos to this album". You get them as push notifications. — OFFLINE. Once you've opened a piece, the score and audio are cached on your device. The app keeps working in concert halls with no signal. The app is free, ad-free, and built for the convention by participants. We don't track you, don't show ads, and don't share your data with anyone outside what's needed to deliver email and push notifications. See the privacy policy for details. To use the app you have to be registered for the convention. If you haven't registered yet, head to bdaa.org first — once you're on the participant roster, your email unlocks the app.
