race_cmd_audio_loopback_test_change_time_cmd(...); 可以知道该函数用来对audio loopback test进行参数配置,其payload域的定义体现在如下结构体中: typedefstruct{RACE_COMMON_HDR_STRUrace_header;uint16_ttest_interval;//unit: 100msuint16_tchecking_interval;//unit: 1msuint16_tis_print_checking_log;}...
三、以DSP中audio loopback test为实现对指令进行测试 首先确定ID的值是多少: 通过查看race_handlers[]中RACE_ID_AUDIO_LOOPBACK_TEST_BEGIN和RACE_ID_AUDIO_LOOPBACK_TEST_END的值可以发现,该loopback test的ID值的范围为0x1000 ~ 0x100F,因此我们在发送指令的时候需要把ID值设置为该范围内。 其次确定参数域...
cold reset后,选择STERO_CODEC_LB测试: 这里的参数在Bluetest3 user guide上有详细说明,我们这里直接采用默认即可。 实际测试结果: 其中黄色波形为MIC_AP上测试的到的,蓝色波形为SPK_LN上测试得到的。可见,audio的loopback测试成功。 审核编辑 :李倩
The Audio LoopBack Test uses an audio loopback cable to sample the output waveform at the microphone input. The sampled waveform is then saved for post-analysis. The sampled waveform must not have long latency. Test Prerequisites Your device must meet the following requirements before you run th...

得益于Audio Precision分析仪硬件的高性能与高精度，基于分析仪自身的输出与输入物理接口，如模拟输出到模拟输入，数字输出到数字输入。在LOOPBACK模式，其延时在出厂时经过校准为0.000S。这意味着当测量一款产品的延时时，Audio Precision分析仪自身带来的延时可以忽略不计。APx516B Analog Unbalance Input 1 to ...
