Hi all, I've loaded this "bazel" build system on Ubuntu 20.04 LTS on a Pentium E5300 box (no AVX/AVX2).
apt install bazel-4.0.0; ln -s /usr/bin/bazel-4.0.0 /usr/bin/bazel bazel build -c opt :encoder_main bazel build -c opt :decoder_main I note the audio samplerate is 16000 whereas Codec2 and the M17 project go with 8000. Running their test script: : export PATH=$PATH:/data/downloads/yy4418/lyra/bazel-bin bazel-bin/encoder_main --model_path=wavegru --output_dir=$HOME/temp --input_path=testdata/16khz_sample_000001.wav bazel-bin/decoder_main --model_path=wavegru --output_dir=$HOME/temp/ --encoded_path=$HOME/temp/16khz_sample_000001.lyra output I20210409 20:36:27.839759 178277 decoder_main_lib.cc:97] Elapsed seconds : 9 I20210409 20:36:27.839819 178277 decoder_main_lib.cc:98] Samples per second : 12246.8 time aplay $HOME/temp/16khz_sample_000001_decoded.wav Playing WAVE '/root/temp/16khz_sample_000001_decoded.wav' : Signed 16 bit Little Endian, Rate 16000 Hz, Mono real 0m8.481s user 0m0.195s sys 0m0.071s ============ So from an 8.5 sec test file, when decoded takes: real 0m11.183s user 0m11.050s sys 0m0.105s W20210409 20:43:22.203222 178355 kernels_generic.h:241] SumVectors: using generic kernel!
