Part Number: OMAP-L137
Other Parts Discussed in Thread: DM3730

We (my self and my students) are using AM/DM37x Evaluation Module and we are programming it with Android OS.

I need to use the board for audio processing (input & output). 

Is there any documentation regarding how to achieve this?

Regards

    Hi Veton,

    TI does not provide Android OS specific audio processing applications but you can use GStreamer under Android or DVSDK.


    Also TI provides a collection of speech, audio, image, and video codecs optimized for its devices including c64x+ and DM3730 under Linux:

    Hi Tsvetolin,

    I am trying to record Audio on the same  AM/DM37X ( TMDSEVM3730 )  board, under Android OS.

    In the document  I found this Notice:

    "

    Important (for AM/DM37x,OMAP35x ONLY)
    Audio capture channels AUXL and AUXR are by default disabled for AM/DM37x,OMAP35x ASoC driver. To enable them, user can use the following 'amixer' commands:

    amixer cset name='Analog Left AUXL Capture Switch' 1 
    amixer cset name='Analog Right AUXR Capture Switch' 1  "

    This is explanation how to enable Audio In (MIC) under Linux, but I haven't found a way to do the same under Android OS.

    Do you have any idea?

    Best Regards,
