DSP Tools Used

Echo Delay

• Convolution

• Sample Rate Calculations

• Audio Normalization

Pitch Modulation

• Short-Time Fourier Transform

• Decomposition of Signal and Replication through pitch shifting

Filters

• Low Pass

  • Butterworth

• High Pass

  • Butterworth

• Band Pass

  • Biquad Parametric EQ

• Band Stop

  • Biquad Parametric EQ

• Convolution of filter coefficients

  • Cascades many filters into one filter

  • Saves processing time because filtering function only needs to be called once

Loops

• Sampling continuous-time audio signals using buffering for reconstruction
