Create a draft of the interface/graphical user interface design - you can use powerpoint shapes or the APPDesigner feature in MATLAB - submit only the image of the proposed interface Design Considerations: - Able to record audio and store into a variable or import/load ".mat" files - able to playback sound - plot original signal and its FFT - able to create filter (FIR (Act \#4) and IIR (Act \#5) with user defined (order and cut-off freq) - able to apply different filters (FIR (Act \#4) and IIR (Act \#5) - display the pole and zeroes, impulse response, frequency response of filters created - Plot new waveform and its FFT - Playback filtered audio Create a draft of the interface/graphical user interface design - you can use powerpoint shapes or the APPDesigner feature in MATLAB - submit only the image of the proposed interface Design Considerations: - Able to record audio and store into a variable or import/load ".mat" files - able to playback sound - plot original signal and its FFT - able to create filter (FIR (Act \#4) and IIR (Act \#5) with user defined (order and cut-off freq) - able to apply different filters (FIR (Act \#4) and IIR (Act \#5) - display the pole and zeroes, impulse response, frequency response of filters created - Plot new waveform and its FFT - Playback filtered audio
