A DSP algorithm, a Pitch / Speed Shifter has been ported from the VS1005 to the VS1010. The Pitch / Speed shifter allows for independent control of an MP3 file's playback speed and pitch. It can be used in various applications, including but not limited to:

• DJ usage where it is very useful to be able to control playback speed and pitch independently.
• Language learning where adjusting speed without affecting pitch is very useful.
• Audio book devices where speed control without affecting pitch is convenient.
• Karaoke devices where pitch control can be used to match the range of the karaoke singer.

The Pitch / Speed Shifter can be downloaded from the VSDSP Forum.

The VS1005 operating system VSOS 3.61 has been released. This version recognizes the Internal/External SPI FLASH file system also if the device has been partitioned. It also makes it possible to modify kernel debug level from the command line.
