Hello Poncho,
Welcome aboard! ADI has made available for download a remarkable DSP book. Both myself and others are exploring DSP through this book and by experimenting with one of the kits. For example, I remember a musician who taught himself DSP this way and designed an ultrasonic assist device for the blind! You'll find the DSP book here: The Scientist & Engineer's Guide to Digital Signal Processing
SigmaStudio's drag-and-drop programming along with one of the SigmaDSP evaluation boards (such as the ADAU1701MINIZ) can get you started quickly. The evaluation boards come with a small startup guide that gets you running with a simple project. Afterward, continue learning with the book mentioned above, as well as searching and asking questions on this forum.
Best regards,
Bob
