Realtime AEC效果不稳定，有时有效果有时无效

[huangjunsen0406]

作者你好！
我在 macOS 上使用这个 aec 库做实时回声消除时，发现效果比较不稳定，具体表现是：

有时候能正常抑制回声，通话对方听不到自己声音的回声

有时候完全无效，回声直接透传回麦克风

同样的配置在 Windows 上表现更稳定

我想请教一下：

aec 在 macOS 下是否需要做额外的配置？

是否与 macOS 系统音频 API（如 CoreAudio）或设备驱动有关系？

在 macOS 上有没有推荐的采样率、帧长或者延迟配置？

是否有其他可选的调试方法来确认参考信号是否正确？

但还是没找到稳定的解决方案。
如果方便的话，请帮忙指点下，非常感谢！

Hello author! When using this aec library for real-time echo cancellation on macOS, I've found the performance to be quite unstable. Specifically:

Sometimes it properly suppresses echo, and the other party doesn't hear their own voice echoing back
Sometimes it's completely ineffective, with echo passing straight through to the microphone
The same configuration works more reliably on Windows

I'd like to ask:

Does aec require any special configuration on macOS?
Could this be related to macOS system audio APIs (like CoreAudio) or device drivers?
Are there recommended settings for sample rate, frame length, or latency on macOS?
Are there other debugging methods available to confirm whether the reference signal is correct?

I still haven't found a stable solution. If convenient, please provide some guidance. Thank you very much!RetryClaude can make mistakes. Please double-check responses.

@thewh1teagle I am gonna test this out soon might be a bug ?
