Wikimedia accepts and encourages uploading audio files on Commons. Audio files, like images, must be freely licensed. The preferred audio container format is Ogg but other file types are supported. When uploading audio files use the file type oga; for video ogv, to differentiate amongst the generic ogg file type. However, mp3 format is allowed.

FLAC, both, embedded in the Ogg container or in its native container format is supported for applications where lossless compression is required, for example projects where a file has to be edited multiple times.

To convert your audio to one of the allowed formats, you can use most video converters, they can also handle audio without video or extract audio from video. The command line tool ffmpeg is available for various operating systems and internally used by many tools with a graphical user interface. On Linux check out OggConvert. For Windows and Linux you can use VLC to convert e.g. m4a to oga.

video2commons can be used to extract the audio from a video hosted on a variety of sites, including Commons itself (the video file URL itself has to be input, not the file page URL).

When recording sounds or spoken samples with your own equipment please take care of the following aspects. Make sure to eliminate all background noises. Though, it is possible to remove unwanted noise from the audio stream afterwards, it is better to minimize your editing work. Furthermore, it is advised to use a high quality microphone. Built in hardware microphones, especially those from laptops, are considered to produce low quality recordings which include clipping, noise and therefore a low SNR.

Audacity is not only able to record audio, but also offers a multi platform editing tool for an unlimited number of audio streams. The Audacity user manual offers suggestions tailored to specific use-cases such as digitization of analogue material, so read it.

Uploaders must ensure they have gathered all rights necessary, including (but not limited to) recording rights, and rights from any interpreters, performers, composers and lyricists involved, wherever applicable. These individual rights should be specified separately on each file description page of audio and video files.
