Hi, I’m wondering how can I get the speech/music classification result when encoding the audio in opus 1.3.1? I found in the file opus_encoder.c, there is a opus_encoder_ctl request as OPUS_GET_VOICE_RATIO_REQUEST, so I wrote in my program the below code: #define OPUS_GET_VOICE_RATIO(x) 11019, __opus_check_int_ptr(x) int32_t voiceRatio; opus_encoder_ctl(encoder, OPUS_GET_VOICE_RATIO(&voiceRatio)); LOGI("voice ratio:%d", voiceRatio); But it always return -1. And then I found that in the opus_encoder.c, the classification can only enable when #ifndef DISABLE_FLOAT_API, but I’m not sure if & where we define the DISABLE_FLOAT_API? How can I build the lib without this macro? I build the lib for IOS, using the script at https://github.com/chrisballinger/Opus-iOS <https://github.com/chrisballinger/Opus-iOS> It takes me several days to test but no success, can you help me? Thank you very much! -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.xiph.org/pipermail/opus/attachments/20191113/d97ec1a1/attachment.html>
