Carregamento Sob Demanda

This is a work-in-progress translation to Brazilian-Portuguese of On-Demand Loading.

Este é um trabalho em progresso de uma tradução para português do Brasil de Carregamento Sob Demanda.

Com a importação normal de arquivo, você deve esperar pela carga de um diálogo de progresso completar enquanto Audacity calcula a forma de onda. Isto pode levar vários minutos com arquivos grandes não comprimidos como WAV. Quando "Carga Sob Demanda" está habilitada em Preferências, você pode tocar, editar e ver o áudio quase imediatamente de qualquer ponto escolhido, enquanto a imagem da forma de onda ainda está sendo calculada em segundo plano.

Uso

Para usar Carga Sob Demanda, vá na aba Importar / Exportar de Preferências, e na seção "Quando importar arquivos de áudio", marque "Ler arquivos de áudio não comprimidos diretamente do original":

Then import an uncompressed file, for example WAV or AIFF, via any means (drag-and-drop, File > Open... or File > Import > Audio...). A sequence of patterned blocks representing the uncomputed waveform appears at once. The blocks are then progressively replaced from left to right by the computed waveform. To change the point from which the waveform should be computed, click at the leftmost point from which you want the waveform drawn. In the below image, we clicked in the center of the track and after a second or two, the waveform now starts being drawn rightwards from the cursor point:

Once the computation point has reached the end of the track, any uncomputed waveform will be drawn from right to left, unless interrupted by clicking elsewhere at an uncomputed point.

Multiple files may be imported simultaneously, and the waveform computation point moved from one to the other by clicking in the required track.

The percentage of the waveform that has been computed is displayed on the Status Bar, as shown at bottom left of the image above. When multiple files are being imported, the Status Bar will display the overall percentage of the multiple tracks that has been computed. To make Status Bar display the percentage completion of a particular track, move the mouse over that track.

In the future we hope to extend On-Demand processing to compressed formats such as FLAC and MP3, to formats imported via the optional FFmpeg library, and to effects.
