Audio capture to WAV file

Products: Video Capture SDK .Net

WAV, short for Waveform Audio File Format, is a standard for storing audio on PCs. It's a variant of the RIFF bitstream format and typically uses linear pulse-code modulation (PCM) for uncompressed audio. WAV is known for its high quality, making it popular for professional audio applications but resulting in large file sizes.
