Streaming Audio on Windows

[Sascha353]

I try to get the raw PMC audio stream on Windows to work but didn't succeed so far. As far as I can tell VLC should be capable to stream it with this parameters:

echo "This sentence is spoken first. This sentence is synthesized while the first sentence is spoken." | piper --model en_GB-jenny_dioco-medium.onnx --output-raw | "C:\Program Files\VideoLAN\VLC\vlc.exe" --demux=rawaud --rawaud-channels=1 --rawaud-samplerate=22050 --rawaud-fourcc=s16l -

or this without the GUI:

echo "This sentence is spoken first. This sentence is synthesized while the first sentence is spoken." | piper --model en_GB-jenny_dioco-medium.onnx --output-raw | "C:\Program Files\VideoLAN\VLC\vlc.exe" -I dummy --demux=rawaud --rawaud-channels=1 --rawaud-samplerate=22050 --rawaud-fourcc=s16l -

Unfortunately it's not working as expected. I can hear a faint voice during the playback but it's mostly white noise and crackle.

Any advice for VLC or any other option on Windows for audio streaming?

Know issue for Windows apparently see [/issues/213]. Just need to wait a new Windows release, or try to compile with the modifcations ^^ If you try, let me know, i'm interrested :D @synesthesiam If you compile a new Windows, i would be glad to beta test it :D

Please try the Windows version of the latest release: https://github.com/rhasspy/piper/releases/tag/2023.11.14-2 This includes (hopefully) a fix for Windows streaming.

Just to add to this topic; sox.exe (Sound eXchange) can also be used to stream audio on Windows.

echo "This sentence is spoken first. This sentence is synthesized while the first sentence is spoken." | piper --model en_GB-jenny_dioco-medium.onnx --output-raw | sox.exe -t raw -b 16 -e signed-integer -r 22050 -c 1 - -t waveaudio pad 0 0.010 >NUL 2>&1
