Hello! Here is an immediate update to the devCrypt driver. There was an issue that would show itself if you read two files simultaneously from an SD card, one file in plaintext and the other file encrypted. This has now been corrected. The documentation now also includes speed tests. In short, you c...

Hello!

At the moment, only 16 bits is supported.

Hello! Have you been able to solve your issue? If not, could you save the beginning of a stream to a file so that we could check whether all headers are formatted in such a way that VS1053 would be happy with it?

Hello!

Unfortunately the current Reverb Generator does not support adding an Equalization Filter that would only apply to the Wet part of audio.

Can you explain why you want to do this? If we understand the reason, perhaps we can help.

Just to add to the previous message, you can either turn all filters off by calling: SetEqu 1 0 SetEqu 2 0 [...] SetEqu 16 0 ... or from C code something like ... #include <aucommon.h> #include <vsos.h> int i; for (i=0; i<16; i++) { struct FilterEqualizer fltEqu = {0}; ioctl(fp, IOCTL_AUDIO_SET_EQU_...
