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.

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.

Converting audio[edit]

Interface de usuário do Audacity

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.

With modern browsers the scripts Opusenc.js and Flac.js convert aiff, wave and raw audio to Opus or FLAC.

Criando e editando áudio[edit]

Quando registrar sons ou amostras de fala com seu próprio equipamento, tenha cuidado com os seguintes aspectos. Tenha certeza que eliminou todos os ruídos externos. Embora, seja possível remover ruídos indesejados do fluxo do áudio, é preferível fazê-lo antes para minimizar o seu trabalho de edição. Além disso, é aconselhável utilizar um microfone de alta qualidade. Microfones internos, como os utilizados em notebooks, produzem gravações de baixa qualidade, que incluem saturação, ruído e por este motivo um baixo pt:SNR.

O Audacity não é apenas capaz de gravar áudio, ele também oferece uma ferramenta de edição multi-plataforma para um ilimitado número de fluxos de áudio.

A note about copyright[edit]

Uploaders must ensure they have gathered all rights necessary, including but not limited to recording rights, rights by the interpret(s), by the composer and of the lyricist, whenever applicable. These individual rights should be specified separately on each file description page of audio and video files.

Copyright collecting agencies represent the usage rights stemming from authors' rights for works of their members. Often authors are forced to transfer exclusive usage rights for all their works to the agency as required by the statute of the collecting agency, and even the authors themselves need the agency's permission to publish their own work under a free license as a consequence. Most huge agencies will not grant permission for Wikimedia Commons acceptable licenses.
