KK audio test software is independently developed by Aupuxin Enterprise, which is used to control its audio analyzer for acoustic testing. After years of ongoing updating, it has been developed to version V3.1 .In order to meet the different types of test requirements in the market, KK has continuously added the latest test functions: open loop test, transfer function measurement, directivity measurement, waterfall diagram display, voice clarity score, etc.

Directivity test interface

The directivity test function is mainly used to test the sound of the speaker or the sound pickup range of the microphone. Equipped with the Aopuxin rotary table, it can control the steering angle of the product in real time for accurate measurement .

POLQA Voice Quality Assessment

In the process of sound transmission, the quality of  voice plays a very critical role. However, the conventional frequency response curve cannot highlight the situation of the human voice, so we introduced the POLQA voice quality measurement algorithm in the test platform, which can effectively measure  human voice.

Professional audio product test software

KK1.0 test software is a professional audio product test software that can fully test audio parameters，Including: frequency response, total harmonic distortion, separation, signal-to-noise ratio, balance, intermodulation distortion, common mode rejection ratio, acoustic sensitivity, acoustic horn abnormal sound, horn T-S parameters and other parameters.The test is stable and reliable, the operation is simple and convenient, and the test report can be automatically generated, saved and printed, which greatly improves the user’s work efficiency.

In addition, we can customize the software according to user needs. Go to www.apxbbs.

PCBA parameter test

KK1.0 has a friendly Chinese operation interface, and the finished headset can be tested its acoustic parameters of the speaker and microphone with one click.

PCBA parameter test is stable, 8 PCBA plug and test;

Supports 16 channels /8 PCBA, and detects 8 PCBA simultaneously in 20 seconds (20s /8 = 2.5s);

Abnormal sound test is accurate and fast, and can replace manual listening (Type C headphones).

Acoustic test time is also very short, one-click automatic test of all parameters;

Completely replace manual listening (noise, air leakage, noise) and can test parameters like  frequency response, distortion, earphone balance, polarity, delay, speaker impedance and F0 and so on.

Display all parameters on the one interface

Display all parameters on one interface Simple and quick to see real-time debugging results. You can debug parameters such as frequency response, FFT, power, and gain.

KK1.0 can automatically generate test reports, such as one-key automatic test  can get all electrical parameters including frequency response, distortion, balance, phase, signal-to-noise ratio, power, separation and other parameters.

For example, the sound card converter test can test frequency response, distortion, phase, balance, signal-to-noise ratio, power, separation and other parameters.
