There is no specific or singular program in Linux to "open an audio file." Just as in Windows, there are a large variety of media players to choose from. These include Amarok, Rhythmbox, Juk, VLC, MPlayer, Banshee, and Audacious.
You will need a media player software application to listen to an audio file on a computer. That are many different types of media player software applications that you can download for this purpose to your computer.
Audacity, an open source application for Windows, Mac and Linux can change the pitch of a file. It is available for free at audacity.sourceforge.net
Player
By using whatever tool is associated with that file type. There are dozens of text, graphics, audio, and video editors.
Any type of audio file converter can be downloaded. The software is available for download in plenty of places online. There are also some online audio converters for use with sites such as Youtube, if you're uncomfortable downloading.
To convert an audio file into a waveform video, you can use software like Adobe After Effects or Audacity. These programs allow you to import the audio file and generate a visual representation of the sound waves, which can then be exported as a video file.

It depends on what you mean by "run the audio file copied from a CD." If you mean you copied a track straight off a CD onto your computer's hard drive then you have two choices: create a virtual CD-ROM drive to play the track; or, two, convert the audio file to a format the media player you have on your PC can play (mp3, wma, etc.). In either case you'll need special software to create the virtual drive or to convert the audio file for playing. If neither option is for you then you should still be able to play your audio CD from your CD-ROM drive using the default audio software that came with Windows.
You can create a waveform video from audio by using video editing software that has a feature to visualize audio waveforms. Simply import your audio file into the software, choose the waveform visualization option, adjust settings as needed, and then export the video with the waveform overlaid on the audio track.
There is plenty of software which allows Linux to work with NTFS file system. For windows there is not as much. But I think Acronis "Backup and Recovery" allows you to read Linux file systems under windows.
The best way to eliminate unwanted noise in a video file is to separate the audio into its own file and run it through filters in an audio editing program like Sound Forge.
