raspberry pi play multiple songs at once

Connect the audio jack to the input of any audio amplifier/music box/radio. You find the Python documentation here.Ĭopy the song you like to play into a subdirectory of the /home/pi folder (e.g. This allows you to select the sound card programmatically when constructing the player instance. To use the USB sound adapter, we wrote a small Python class wrapper that spawns Linux shell commands for the SoX player. Unfortunately it only supports output to the built-in audio card. To check the properties of the default sound card, type amixer.įor the Alsa sound system the Python module pygame may be used. If you are uncertain about the available sound devices type aplay -l. With hw:0 or hw:1 to output the song on the USB adapter of your choice without modifying the. With SoX you can change the sound card on-the-fly by setting the environment variable AUDIODEV to hw:0 or hw:1. (Consult the SoX website for more information).

Many audio formats of your sound file are supported (type sox to display them). Now you play a song from a terminal window with play. To install it on pure NOOBS system, connect the Raspberry Pi to the internet and type SoX is preinstalled on our SD card distribution. We recommend to use the SoX (Sound eXchange) software that is considered to be 'The Swiss Army knife of sound processing programs'. asoundrc that you find in the /home/pi folder. For the current NOOBS distribution you simply edit the file.

You find many information how to change the default sound output to the USB card, but most of them are obsolete due to changes in the Linux distribution.

The quality is not overwhelming, so you better purchase a Raspberry Pi compatible USB sound adapter. From a terminal (console) you type the command aplay to play the file mysong.wav with the ALSA (Advanced Linux Sound Architecture) player via the default sound card that outputs to the audio jack. Sound in different audio formats (most commonly WAV and MP3) can be played with standard sound players. The Raspberry Pi is equipped with an internal sound card that outputs sound to an audio jack. The source code of all examples can be downloaded from here.
