#Python play sound install#

Tested pygame that didn't work with sdl2 - and I did not want to install another version of the sdl.

Tried pyglet which needed avbin for which I didn't find a source or an ARM binary. Checked ffmpeg-python which in fact worked for cool stuff like creating video overlays and converting audio and video, didn't seem to be the right choice for simply playing audio. It is noteworthy that one could instantiate more than one player if that helps (and have them play samples at the same time).Īlternative: gstreamer got Python bindings and mp3 as well as ogg decoding.ġ Installed ffmpeg along with sdl2 and ffpyplayer - didn't get it to play, both using pip3 and installing from github. pause seems to have a small but noticable lag, so likely in the range of a few tens to hundreds of milliseconds.

play feels immediate (push enter, hear sample start).

Time-critical playback of short sound bits

Vlc.libvlc_audio_set_volume(p, volume) # volume 0.100ĭidn't do any long time running tests though (feel free to post another answer about that if going that way). Playing from Python worked straight forward: import vlc 150 other packages and Python-bindings for vlc via sudo apt-get install vlc Does anyone know of a simple cross-platform Python 3 way to play an audio tone of a specific frequency I am developing a sorting animation to help beginners understand sorting algorithms and would like to play sounds that represent the magnitudes of the values being swapped. It's using a USB soundcard and alsa but it's likely to work with an I2S soundcard as well. On a Pi Zero with a recent Raspbian and Python 3.6 I tried a few things 1 that didn't work that well out of the box and finally I settled for vlc. Currently I am stuck with pygame, that has this weird glitch, where the only workaround is to do secret re-initialisation at regular time intervals. If there are reliable alternative to pygame, I'd gladly use that. But unfortunately it behaves bad, when the app has been running for long time. So a method more native to Python is sought.ĭespite the load of heavy reference requirements, I've currently settled on pygame. Launching an external player in separate process to play sounds might be acceptable for a 'media player' application, but not reliable when you need to play little bits of sounds with precise timing. Pyglet seems to be abandoned, at least the AVbin lib it relies on definately is.

For example, I can use headless vlc player to stream audio from youtube or various internet radio stations.īut I was quite surprised the options are quite poor when you need to play sound from Python. By default, Zero does not have audio output, but I have set up an I2S amp and speaker, following this guide: I have been trying to find a reliable method to play sound on my Pi Zero W, in Python.
