Record and Play Audio. For video data, the term “file format” often refers to either the container format or the codec.A container format describes the layout of the file, while a codec describes how to encode/decode the video data. Video Reading Performance on Windows Systems:To achieve better video reader performance on Windows for MP4 and MOV files, MATLAB uses the system's graphics hardware for decoding.

Once the process is complete, the folder containing the converted audio files will open automatically. These functions write audio data to a file using specific file formats. For videos which also contain audio data, the rate of the audio data will be determined as the rate of the video multiplied by the number of audio samples passed in.
