Closed YogarajRamesh closed 2 years ago

YogarajRamesh commented 2 years ago

Hi @igorski

  1. I am try to add processor to getInputChannel() but i got error
    error: cannot find symbol dcfilter = new DCOffsetFilter(1); ^ symbol: variable dcfilter Code snippet private DCOffsetFilter dcfilter; dcfilter = new DCOffsetFilter(1); _engine.getInputChannel().getProcessingChain().addProcessor(dcfilter );

    1. I am trying to add “reverb” to getInputChannel() while using OUTPUT_CHANNELS = 2 is working fine but while using OUTPUT_CHANNELS = 2 i got error
      Terminating with uncaught exception of type std::out_of_range: vector

Thanks in advance

Hi @YogarajRamesh

For .1, turns out the DC offset filter was not exposed to the Java API. This has been addressed in fec41190772f5b42761834ad05017114c80c96e5

For .2, the legacy reverb effect wasn't mono compatible, which all processors in MWEngine actually should be. This has been addressed in d539a6f6d9fce3e8fa40d08b8227cfe10b06ffa3
