This online tuner analyzes the incoming audio signal in real time, detects its fundamental frequency, and compares it to the target pitch defined by standard tuning (A=440 Hz). The tuner indicates whether the played note is sharp, flat, or correctly tuned, allowing for precise pitch adjustment.
The tool is optimized for instruments in the keys of C, B♭, and E♭, automatically interpreting their transpositions to display accurate pitch information.
