The Braw Bagpipe Tuner app is a tool for tuning and learning to play the bagpipes. It can tune a wide range of instruments that use a variety of musical tones.

It uses a microphone to listen to the sound of the bagpipe and then use this information to calculate the exact pitch that you are playing. This pitch is the note that you have to play to get the right tone.

The app can also calculate the exact frequency of the note that you are playing. It does this by analyzing the waveform of the sound that you are hearing. This is done by using a filter that is a perfect match for the frequency that you are tuning.

This is done by using a technique called autocorrelation. This is a type of filter that can identify the frequency of a sound.

The app can also be used to learn the correct tuning for the bagpipes. This is done by using a reference note that is the same note that you are tuning to.
