Another way of representing audio data is by converting it into a different domain of data representation, namely the frequency domain. Source Separation Library!"). Bag AuthorInformation I have been practicing with this kernel for days and convert the codes to python since it's my language of choice. Gives a good foundation to exploring audio data. There are a few more ways in which audio data can be represented, for example. All of the libraries below let you play WAV files, some with a few more lines of code than others: 1. playsoundis the most straightforward package to use if you simply want to play a WAV or MP3 file. This is called sampling of audio data, and the rate at which it is sampled is called the sampling rate. Also the body language of the person can show you many more features about a person, because actions speak louder than words! AuthorInformation Examples of these formats are. Thanks. Any references?
