The processed audio signal is cast to integer before being sent to the BeagleBone Black ALSA (Advanced Linux Sound Architecture) Audio Playback block, which sends audio to the sound card of the target hardware for payback using ALSA driver framework. A GUI is provided to assist run-time adjustment of the filter coefficients.ģ. Then, it is processed using a 3-band parametric audio equalizer, which consists of three second-order (bi-quadratic) filters whose coefficients can be adjusted to achieve a desired frequency response. The audioSignal with int16 data type is pre-processed and cast to single precision. The audioSignal is read from a wave file called guitartune.wav in the model InitFcn callback.Ģ. The input audio signals are generated using the Signal From Workspace block, which outputs the audioSignal at a rate of 44100 samples per second.
