The VS1005 BreakOut Board MkII shows how to implement an inexpensive HiRes Recorder, capable of recording up to 96 kHz 24-bit resolution to a microSD card. A 4 Mbit VS23S040 SRAM IC is used to offer buffering that is essential to recording to SD cards. Card sizes up to 256 GB have been tested, giving an continuous recording time in excess of 120 hours using the highest quality settings.
