Echo doesn't cancel with PortAudio

    • Open Issue created by thewh1teagle @thewh1teagle

    Hey!

    Recently I created Rust bindings to speex for acoustic echo cancellation.

    I packaged it into python library as well.

    It works well with wav file but when trying to cancel echo with PortAudio in Python it doesn't cancel it.

    I'm not sure what I'm missing, maybe it's related to filter_length? this is the Python code:

    microphone.py (The instruction to run on top)

    It uses speex_echo_cancellation and speex_preprocess_run in lib.rs
