AudioPhase

**AudioPhase** is an acoustic analysis tool designed for sound engineers, installers, and professionals who need to quickly check polarity, phase, and cancellation between speakers.

A speaker connected with reversed polarity can cause significant bass loss, cancellations, and a much lower overall system performance. AudioPhase helps detect these problems using your Android device's microphone and specially designed test signals.

With AudioPhase you can:

• **Check the relative polarity between two speakers.**
Save one speaker as a reference and immediately compare it to a second to see if they are operating with the same polarity or if one is reversed.

• **Analyze phase and delay.**
View the correlation, relative delay, and a phase estimate between the measured signals.

• **Detect acoustic cancellations.**
Measure each speaker individually and then both working together to identify significant summing losses or cancellations.

• **Generate test tones.**
Select different frequencies to test bass, midrange, and other sound systems.

• **Perform frequency sweeps.**
Use sweep signals to check system behavior across different frequency ranges.

• **Identify incorrect measurements.**
AudioPhase verifies the quality of the captured signal and alerts you when a measurement is not reliable enough to provide a result.

• **Receive vibration alerts.**
Recognize measurement results and errors without needing to constantly look at the screen.

AudioPhase is designed for ease of use: simply place your phone in a fixed position, take a measurement of the first speaker, and compare it to the others.

Ideal for:

• PA Systems
• Subwoofers
• Sound Installations
• Nightclubs and Events
• Repair Shops
• Audio Technicians
• Speaker and Cable Testing

**Privacy**

The audio used during measurements is processed locally on the device. AudioPhase does not require a user account or internet connection to perform its main functions.

**AudioPhase — finds the speaker that's working against the others before you waste time searching for the problem by ear.**
