1. Select the sampling frequency in the drop down provided.
2. Enter the value for tone frequency.
3. Enter the volume for the tone.
4. Click on Listen button to visualize the plot in the figure and listen to the tone.

If the sampling frequency is X, try listening to tone frequency of X/2. Why does this happen?

If the sampling frequency is X, and tone frequency is Y, try listening to tone frequencies Y and X-Y. Why does this happen?

1. Select the envelope (either ADSR, Rectangular or Exponential Decay) in the drop down provided.
2. Enter the value for tone frequency.
3. Enter the volume for the tone.
4. Click on Listen button to visualize the plot for the envelope in the figure and listen to the tone masked under that envelope.

1. Select the envelope (either ADSR, Rectangular or Exponential Decay) in the drop down provided.
2. Enter the value for fundamental frequency.
3. Enter the harmonic numbers to be combined.
4. Enter the corresponding volumes for each harmonic number.
5. Click on Listen button to visualize the plot for the note in the figure and listen to it.

Instructions

• Choose the window from the dropdown and listen to them. To add new notes, click on Add note button to fill the corresponding values in the new set of boxes on the right
• To remove a note, click on the "Remove" button under that specific note
• For each note, you will require to enter the fundamental frequency, harmonics, their corresponding amplitudes and note duration
• Enter only one fundamental frequency for that note, multiple harmonics (natural numbers) can be entered in a comma separated manner, and their corresponding amplitudes (in the range 0-1) also can be entered in a comma separated manner and enter only one duration (in seconds) for the note.
• You can add a maximum of 10 notes

NOTE: Add the necessary number of notes before entering the corresponding values. If you add a new note after entering the values for the previous notes, the previous notes' values get cleared.
