I2S有噪音/静电

我通过BLE将Android的音频流传送到PSoC 4,并通过I2S发送接收到的数据以播放它,但是它听起来有噪声/静态-Y。我能够通过噪声听到某种正弦波,当我改变正弦波的频率时,我可以通过扬声器A听到它的变化。向PSoC转发。但是我听不到演讲者的任何讲话,只有噪音。
我在Android上创建了一个WAV文件,听起来不错。我已经尝试从一个文件的一部分,扮演一个正弦波,并直接保存在PSoC作为一个数组,播放,而不是接收到的数据,但它仍然有噪音/静态。
如有任何帮助,我们将不胜感激。

  I am streaming audio from an Android to a PSoC 4 via BLE and sending the received data through the I2S to play it back but the it sounds noisy/static-y. I am able to somewhat hear a sinewave through the noise and when I change the frequency of the sinewave I can hear it change through the speaker attached to the PSoC. However I cannot hear any speech from the speaker, only noise.

I have created a wav file on the Android and it sounds fine. I have tried taking the data from a portion of a file playing a sinewave and directly saving it on the PSoC as an array and playing that instead of the received data but it still has noise/static.

Any help would be appreciated.

你好
请附上这个项目。WAL文件如何通过BLE发送?在PoSO4BLE结束时,您是否测试了WAV文件的正确顺序?
谢谢,

  Hello
 
Kindly attach the project. How are you sending .wav file over BLE? Did you test if the .wav file is received at PSoC4-BLE's end in good order?
 
Thanks,
Hima
