Linux - Without hardware soundcard, capture audio playback, and record it to file

由 二次信任 提交于 2021-02-18 22:10:32
问题 Is such a thing even possible? Is there a possibility to create a virtual sound card and then use for example PyAudio to listen to its output and save it to a file? NOTE that there is no hardware soundcard present on the machine. I have tried a lot of things, especially snd-dummy ALSA module, but I am starting to doubt if I am looking for the right tools. I would be grateful if someone could point me towards at least high-level solution. Preferably something that would work on Ubuntu server.

问题 I'm looking to make an application, who woul'd let me translate any audio going out of the speaker in live stream. This way, i will be able to translate any videoconference from any live stream app(youtube,teams,zoom,etc.). I'm not far from a solution, but not there yet. Src language would be: fr-CA or en-US Dst language would be : fr-Ca or en-US I was able to get audio stream back from speaker with a custom version of pyaudio allowing loopback with the WASAPI of windows.(https://github.com

问题 Firstly, I tried pip install pyaudio But that didn't work... I found that I need PortAudio, so installed it with brew : brew install portaudio That worked and then I restarted my Mac. But pip install pyaudio still doesn't work and I get the below error message: ERROR: Command errored out with exit status 1: command: /Applications/Xcode.app/Contents/Developer/usr/bin/python3 -u -c 'import sys, setuptools, tokenize; sys.argv[0] = '"'"'/private/var/folders/12/44t6pktj77xbqmyp7x368tdr0000gn/T/pip

howto stream numpy array into pyaudio stream?

由 喜你入骨 提交于 2021-02-04 16:06:24
问题 I'm writing a code that supposed to give some audio output to the user based on his action, and I want to generate the sound rather than having a fixed number of wav files to play. Now, what I'm doing is to generate the signal in numpy format, store the data in a wav file and then read the same file into pyaudio . I think this is redundant, however, I couldn't find a way to do that. My question is, can I stream a numpy array (or a regular list) directly into my the pyaudio to play? 回答1: If

PyAudio cannot find any output devices

问题 When I run: import pyaudio pa = pyaudio.PyAudio() pa.get_default_output_device_info() I get: IOError: No Default Output Device Available When I say: pa.get_device_count() It returns 0L . And of course if I list devices for i in range(0, device_count): print("Name: " + pa.get_device_info_by_index(i)["name"]) print("Index: " + pa.get_device_info_by_index(i)["index"]) print("\n") It will not print anything. I'm running Ubuntu 16.04 and have set my default sink by going: pacmd list-sinks pacmd
