Esporta Audio

Dopo aver importato un'onda sonora, potresti volerla esportare in memoria o in un file. Il plugin fornisce funzionalità per esportare audio in vari formati, con opzioni per sovrascrivere il sample rate (ricampionamento) e il numero di canali (mixing).

Formati audio supportati

Il plugin supporta l'esportazione nei seguenti formati audio:

• WAV - Waveform Audio File Format
• OGG VORBIS - Contenitore Ogg con audio Vorbis
• OGG OPUS - Contenitore Ogg con audio Opus
• BINK - Bink Audio (solo Windows x64, Mac e Linux in UE >= 5.0)
• RAW (PCM) - Dati audio Pulse-Code Modulation non compressi (Int8, UInt8, Int16, UInt16, Int32, UInt32, Float32)
