Q 2.How do I create deliverables using DSP Composer?

input to the flasher utility.

aac.exe,dts.exe,os.exe,pl2.exe ..etc.
3. Open the applicable sample .cpa files (installed by dspcondenser.exe in:
C:\CirrusDSP\DSPCondenser\projects\sample_cirrus.zip
The sample files included in thesample_cirrus zip file at the time publication are:
• decoder_aac.cpa
• decoder_ac3.cpa
• decoder_dts9624.cpa

4. DSP Composer is part of the evaluation kit installation. Make sure the latest version of the evalution
kit is installed in ‘C:\CirrusDSP’ folder to avoid any version mismatch issues. If there the version
installed on your system is out-of-date, a screen pops up with a request to update the needed files.
See the out-of-date evaluation kit notice in

version of DSP Composer exists and then replace the older version of the latest version of DSP
Composer..
