Convert DCT to DAU

Understanding dct and dau file formats

DCT files are audio files created by NCH Software's dictation software, such as Express Dictate. These files often contain voice recordings and may be encrypted or compressed for secure and efficient storage. DAU files, on the other hand, are also audio files, but they are typically associated with Dialogic's telephony systems and are used for storing voice prompts or messages in a format compatible with telephony hardware.

Why convert dct to dau?

Converting DCT to DAU is necessary when you need to use dictation recordings from NCH Software in telephony systems that require the DAU format. This ensures compatibility and seamless playback of audio prompts or messages.

How to convert dct to dau

1. Convert DCT to WAV: Use NCH Switch Audio Converter or Express Dictate to export your DCT file to a standard audio format like WAV.
