Exportar audio

Después de importar una onda de sonido, es posible que desee exportarla a la memoria o a un archivo en uno de los formatos compatibles: OGG VORBIS, OGG OPUS, WAV, BINK, RAW (PCM). Si es necesario, también puede sobrescribir la tasa de muestreo (es decir, remuestrear) y el número de canales (es decir, mezclar).

Tenga en cuenta que la exportación al formato BINK solo es compatible en Windows x64, Mac y Linux en UE >= 5.0.
