PurePath Studio TLV320AIC3254 'Example Process Flows’

Other Parts Discussed in Thread: TLV320AIC3254

I am trying to develop a product using the AIC3254.  I have PurePath Studio v5.95 and a TLV320AIC3254 EVM.  I am particularly interested in the processes listed in the ‘Example Process Flows’ folder such as Active Noise Cancelation, Dual Mic Noise Cancelation, AEC Process Flows.  I would like to read whatever is available on the theory of operation of these processes.

Are there write-ups / whitepapers avalible on PurePath Studio ‘Example Process Flows’?

Thanks, Brian

    Our application notes for PPS examples are available in the installation folder \ApplicationNotes

    C:\Documents and Settings\<user>\My Documents\Texas Instruments Inc\PurePath Studio (Portable Audio) MiniDSP 5.95\ApplicationNotes.

    Thank you for this information reference content of the C:\Documents and Settings\<user>\My Documents\Texas Instruments Inc\PurePath Studio (Portable Audio) MiniDSP 5.95\ApplicationNotes folder. 

    There is not an ApplicationNotes folder in C:\Documents and Settings\<user>\My Documents\Texas Instruments Inc\PurePath Studio (Portable Audio) MiniDSP 5.95\. There are however \MyProcessFlows, \ComponentCache, \ComponentLibrary, \UserComponentLibraryolder, folders. 

    I have found an ApplicationNotes folder in C:\Program Files\Texas Instruments Inc\PurePath Studio (Portable Audio) MiniDSP 5.95\ApplicationNotes it contains two files: Multi Band Noise Reduction Application Note.pdf and AIC3254 Acoustic Echo Cancellation Application Note.pdf.  I have printed and read these documents and at this time are a little over my head, but, I am also interested in other the processes listed in the ‘Example Process Flows’ folder such as Active Noise Cancelation, Dual Mic Noise Cancelation.  Is it possible I am missing other available Application Notes?

    Also, I have PurePath Studio v5.95 installed on both a Windows XP and Windows 7 machine (the folders listed above are a little different on the Windows 7 machine but the content is the same).  Is there any problems running PurePath on Windows 7 vs. XP?

    Thanks for your time,

    Brian Weir

    PPS will run fine under Windows 7. The difference in locations for the ApplicationNotes folder is due to a sub-revision change for 5.95 in order to make it compatible with Windows 7. Let me know if you have any problems running PPS in Windows 7.

    I'll check if we have published documents for ANC & DMNC.
