hello

1. I plan to use the new IC of ADAU ADAU1452 ,but i can't find the algorithm of pitch transposer, if i want to the algorithm,

how can i do?

2. If i want to use the algorithm of Parametric EQ with ADAU1442 ,how can i do?

thank you

Hello,

1. The ADAU1452 is so new that advanced algorithms like the

Pitch Transposerhave not yet been coded. So far,Reverbis the only special effect available. Pitch Transposer is available for the ADAU1442 and most other SigmaDSPs. As presently implemented it's not quite up to the task of key-changing music, but may prove useful in other applications.2. The

Parametric EQblock (where you choose the desired response by editing a graphic window) is available for the ADAU1452, but not for the ADAU1442. However, you can build a parametric equalizer for any SigmaDSP by cascading severalGeneral Second-Orderfilters as shown below. Drag the General Second-Order filter to your schematic, then right-click it andgrowthe number of sections you need. Click the blue box in each section to open thesettingswindow, where you can adjust the Parametric EQ controls -- frequency, boost, and Q. You can use theStimulusandProbeblocks to show a response graph, Adjust the filter controls (adding more sections if necessary) to get the desired curve.Best regards,

Bob
