Support Multi-Decoding (MP3, WMA, AAC, OGG, CDDA)
Support Shock-Proof Playback of CDDA
.. Compression:44sec / Non-Compression:11sec
Firmware Upgrade via CD-ROM
Control Servo DSP-IC Directly from DA255
.. A microcomputer to control Servo DSP-IC is not needed.
Heartland’s own “Filesystem Analysis Module” is used.
.. Support ISO9660, HFS, and UDF as CD-ROM format. And also,
.. this filesystem supports the ..playback of CD-R/RW packet write,
...so this solution can be play almost all CD-ROM Media.
This solution can be used as the platform for the development of various kinds of audio apparatus.
It is possible to lower the cost and reduce the developing period by providing solution which is enhanced until the high complete degree on a product level.
Silisand also provides the customizing support for the development of our customer’s products.
