This is the Multimedia Programming project which implements the Audio Algorithms such as changing frequency, data encoding format (PCM) , amplitude, mono or stereo etc.

Question 1:

Write a software in Java that performs following.

1. Generate, play and save (in .wav file) a sinusoidal wave with following user selectable parameters at run-time.

• a. Frequency (upto 20KHz)
• b. Data encoding format (PCM)
• c. Duration of the signal.
• d. Amplitude
• e. Mono or Stereo

2. Capture sound from an input device(i.e. microphone) and save (in .wav file). Create a separate thread for user interface(UI). At any time, the user should be able to enter any of the following minimum requirement.

• a) Stop playing a sound (if playing or capturing)
• b) Increase/Decrease volume (if playing).
• c) Increase/Decrease speed (e.g. fast forward, slow forward)
• d) The UI must be responsive all the time (weather a file is playing or not)
