匯出音訊

匯入音波後，您可能希望將其匯出到記憶體或檔案。此插件提供以各種格式匯出音訊的功能，並可選擇覆寫取樣率（重新取樣）和聲道數（混音）。

支援的音訊格式

此插件支援匯出為以下音訊格式：

• WAV - 波形音訊檔案格式
• OGG VORBIS - 使用 Vorbis 音訊的 Ogg 容器
• OGG OPUS - 使用 Opus 音訊的 Ogg 容器
• BINK - Bink Audio（僅限 Windows x64、Mac 和 UE >= 5.0 的 Linux）
• RAW (PCM) - 未壓縮的脈衝編碼調變音訊資料（Int8、UInt8、Int16、UInt16、Int32、UInt32、Float32）

Blueprint

C++

// Assuming ImportedSoundWave is a UE reference to a UImportedSoundWave object (or its derived type, such as UStreamingSoundWave, UCapturableSoundWave, etc.)

// Export the sound wave to a file
URuntimeAudioExporter::ExportSoundWaveToFile(ImportedSoundWave, TEXT("C:/ExportedAudio.ogg"), ERuntimeAudioFormat::OggVorbis, 100,
    FRuntimeAudioExportOverrideOptions(),
    FOnAudioExportToFileResultNative::CreateWeakLambda(this, [this](bool bSucceeded)
    {
	    // Handle the result
    }));

// Export the sound wave to a RAW file
URuntimeAudioExporter::ExportSoundWaveToRAWFile(ImportedSoundWave, TEXT("C:/ExportedAudio.raw"), ERuntimeRAWAudioFormat::UInt16,
    FRuntimeAudioExportOverrideOptions(),
    FOnAudioExportToFileResultNative::CreateWeakLambda(this, [this](bool bSucceeded)
    {
	    // Handle the result
    }));

// Export the sound wave to a buffer
URuntimeAudioExporter::ExportSoundWaveToBuffer(ImportedSoundWave, ERuntimeAudioFormat::Wav, 100,
    FRuntimeAudioExportOverrideOptions(),
    FOnAudioExportToBufferResultNative::CreateWeakLambda(this, [this](bool bSucceeded, const TArray64<uint8>& AudioData)
    {
	    // Handle the result
    }));

// Export the sound wave to a RAW buffer
URuntimeAudioExporter::ExportSoundWaveToRAWBuffer(ImportedSoundWave, ERuntimeRAWAudioFormat::Float32,
    FRuntimeAudioExportOverrideOptions(),
    FOnAudioExportToBufferResultNative::CreateWeakLambda(this, [this](bool bSucceeded, const TArray64<uint8>& AudioData)
    {
	    // Handle the result
    }));
