Moritz, Thank you.
Although your suggestion did not work, you gave me enough information to find one that did. The following works from a bash prompt. ffmpeg -i $INPUT -af 'lv2=plugin=https\\:// github.com/lucianodato/speech-denoiser' $OUTPUT Now I have a separate problem which is: *Plugin <https://github.com/lucianodato/speech-denoiser <https://github.com/lucianodato/speech-denoiser>> not found* root@b88297120832:/data# *ffmpeg -i $INPUT -af 'lv2=plugin=https\\://github.com/lucianodato/speech-denoiser <http://github.com/lucianodato/speech-denoiser>' $OUTPUT* ffmpeg version 4.1.3-0ubuntu1 Copyright (c) 2000-2019 the FFmpeg developers built with gcc 8 (Ubuntu 8.3.0-6ubuntu1) configuration: --prefix=/usr --extra-version=0ubuntu1 --toolchain=hardened --libdir=/usr/lib/x86_64-linux-gnu --incdir=/usr/include/x86_64-linux-gnu --arch=amd64 --enable-gpl --disable-stripping --enable-avresample --disable-filter=resample --enable-avisynth --enable-gnutls --enable-ladspa --enable-libaom --enable-libass --enable-libbluray --enable-libbs2b --enable-libcaca --enable-libcdio --enable-libcodec2 --enable-libflite --enable-libfontconfig --enable-libfreetype --enable-libfribidi --enable-libgme --enable-libgsm --enable-libjack --enable-libmp3lame --enable-libmysofa --enable-libopenjpeg --enable-libopenmpt --enable-libopus --enable-libpulse --enable-librsvg --enable-librubberband --enable-libshine --enable-libsnappy --enable-libsoxr --enable-libspeex --enable-libssh --enable-libtheora --enable-libtwolame --enable-libvidstab --enable-libvorbis --enable-libvpx --enable-libwavpack --enable-libwebp --enable-libx265 --enable-libxml2 --enable-libxvid --enable-libzmq --enable-libzvbi --enable-lv2 --enable-omx --enable-openal --enable-opengl --enable-sdl2 --enable-libdc1394 --enable-libdrm --enable-libiec61883 --enable-chromaprint --enable-frei0r --enable-libx264 --enable-shared libavutil 56. 22.100 / 56. 22.100 libavcodec 58. 35.100 / 58. 35.100 libavformat 58. 20.100 / 58. 20.100 libavdevice 58. 5.100 / 58. 5.100 libavfilter 7. 40.101 / 7. 40.101 libavresample 4. 0. 0 / 4. 0. 0 libswscale 5. 3.100 / 5. 3.100 libswresample 3. 3.100 / 3. 3.100 libpostproc 55. 3.100 / 55. 3.100 Guessed Channel Layout for Input Stream #0.0 : stereo Input #0, wav, from '/data/sample_car.wav': Metadata: encoder : Lavf58.12.100 Duration: 00:01:05.02, bitrate: 1411 kb/s Stream #0:0: Audio: pcm_s16le ([1][0][0][0] / 0x0001), 44100 Hz, stereo, s16, 1411 kb/s File '/data/sample_car.sdenoise.wav' already exists.
