Transfer Function measurements offer signif icant advantages over traditional Band Spectrum measurements for loudspeak er calibration\, providing phase\, coherence\, and reflection arrival time data. This is crucial as more loudspeakers come with built-in signal proc essing\, including phase correction. Transfer Function measurements ensure that such processing aligns with the speaker's phase correction. However\ , Transfer Function measurements require two channels: a reference signal and a microphone. In environments with limited routing options\, this can be challenging. The paper introduces 'Virtual Reference\,' a method that s implifies this by using a recording of the reference signal. Virtual Refer ence compares the microphone signal to this recording and plays its own re ference signal when necessary\, allowing the analyzer to operate normally. Additionally\, Virtual Reference addresses samplerate discrepancies betwe en devices\, ensuring stable phase traces and accurate measurements despit e minor deviations in samplerate.
