由 梦想的初衷 提交于 2021-02-11 12:27:09
问题 I am setting up google's speech-to-text in a node/express environment on Google App Engine. I have an Angular app that communicates to the server via websockets. This all works perfectly on local host, but when my angular app points to the App Engine instance it does not. It can connect fine - sends connection msg back/forth. And it runs my google speech connection fine. However I get an error in the bit where i try to access the mic stream. The error message isn't much use: ERROR with

How to run same code on multiple files, or all files in directory

由 旧街凉风 提交于 2021-01-29 09:14:50
问题 so I am very new to coding and recently wrote a little program that involved R and sox.

Is this possible? Any help would be greatly appreciated. Thanks! EDIT: Actually, I should

pipe sox play command to stdout

由 倖福魔咒の 提交于 2020-12-31 06:12:45
问题 So I'm currently trying to stream my microphone input from my raspberry pi (rasbian) to some sort of network stream in order to receive it later on my phone. In order to do this I use arecord -D plughw:1,0 -f dat -r 44100 | top pipe the soundstream from my usb-microphone to stdout which works fine as far as I can see but I needed it to be a bit louder so I can understand people standing far away from it . So i piped it to the sox play command like this : arecord -D plughw:1,0 -f dat -r 44100|
