Speaker Test

Speaker Test serves as a versatile tool for testing speakers, ideal for anyone looking to evaluate new purchases or assess the performance of existing audio systems. This Android app functions as a straightforward sound generator, creating sine waves ranging from 20Hz to 20kHz and various types of noise including white, pink, and brown. This allows you to gauge speaker quality effectively, assuming familiarity with how these sounds should typically be perceived.

Functional Features for Effective Testing

To utilize Speaker Test, simply connect your smartphone’s headphone output to the input of an amplifier and activate the play function. The sound is generated in mono and supports different sample rates from 8000Hz to 44100Hz, along with adjustable sound buffer sizes. This flexibility caters to different audio testing requirements, ensuring that you can customize the testing process according to your needs.

How to Address Audio Dropouts

If audio dropouts occur during use, it might indicate a limitation of your device's CPU or memory. Adjust the sample rate to a smaller setting or increase the buffer size to mitigate this issue. Persistent dropouts at the lowest settings could hint at device limitations.

Future Enhancements for Speaker Test

While currently optimized to perform specific functions in its current design, Speaker Test plans to introduce new features soon. These include log scale generations, stereo sound output, phase testing capabilities, and additional sound generation options. A redesigned user interface is also in progress, aimed at enhancing the user experience.
