send_audio_file returnes NoneType. about alexa-voice-service-client

[Tagge]

This actually means that your audio file is not 'audible' to Alexa and that it returns nothing as a result. My problem was that the audio I was sending wasn't properly encoded (16000 hz sample rate, single channel, signed PCM is the way to go). When that was fixed I was able to get a result back.

@Tagge thanks for the explanation

@Tubinex did you solve the problem?

[Tubinex]

@richtier No, unfortunately I get my audio straight from Discord and I haven't figured out how to convert it to the correct format
but thanks anyway, maybe I'll find a way!

[richtier]

ah yes audio can be hard if there is little documentation.

in case it helps, if it's webaudio good news is I've done that myself: https://github.com/richtier/voice-command-lifecycle/blob/master/command_lifecycle/helpers.py#L23

used that in related project https://github.com/richtier/alexa-browser-client/

@Tubinex I was able to get Discord's audio 48k sample rate 2 channels -> 16k PCM 1 channels. Its a stream transformer in Node.JS though, lmk if you want it.
