The new revision of the VS1063 AEC (Acoustic Echo Cancellation) appnote shortly explains how to test that AEC is running. It also shows a case study on how to improve acoustic design.

The new minor release of the VS1005g Datasheet clarifies a few registers and offers a top and bottom photo of the chip.

VS1063a Datasheet v1.11 corrects definitions for the AD Mixer.

A new variant of VS1063a, called VS1163a, has been added to the VS1063a Datasheet.

VS1163a omits MP3 encoding capabilities, but otherwise it is 100% compatible with VS1063a.

The new appnote corrects an error in how to read the DREQ pin status with software.

The VS1053 Playback and Recording AppNote v1.03 is a minor bugfix to the previous release: recording Pause Key 'p' has been removed from the user interface because that was a VS1063-only feature.

The VS1063 Datasheet, VS1063 Hardware Guide, and VS1063 Programmer's Guide have been updated to version 1.02.
