I want to know if Jami’s plugin Audio filter has the function of a voice changer?
I think it would be great if there was a voice change function during voice calls。

Unfortunately not.

filtergraph:

void
FilterAudioSubscriber::setFilterDescription(const int pSampleRate, const int pSamples, const int pFormat)
{
    int rSamples = 1024; // due to afir internal fifo
    int midSampleRate = pSampleRate * rSamples / pSamples;
    std::string outFormat = av_get_sample_fmt_name((AVSampleFormat)pFormat);
    filterDescription_
        = "[ input ] aformat=sample_fmts=s16:sample_rates=" + std::to_string(midSampleRate)
          + ":channel_layouts=stereo [ resample1 ] , "
          + "[ resample1 ] [ ir0 ] afir=maxir=1:wet=10:dry=10:irgain=1:irfmt=mono:maxp="
          + std::to_string(rSamples) + ":minp=" + std::to_string(rSamples) + " [ reverb ] , "
          + "[ reverb ] aformat=sample_fmts=" + outFormat + ":sample_rates="
          + std::to_string(pSampleRate) + ":channel_layouts=stereo ";
}

Also, it cannot be used on Android because Windows or Linux already have many voice changers, while Android does not
