Arduino Audio DAC Options
In this articleย�Davidย� play around the code Michael Smith created for a PWM based DAC. Davidย� modified his code so that other DAC options could be tried.ย�Davidย� compare the 8-Bit PWM DAC with the R2R DAC at various numbers of bits. You might be surprised at how well a 4-bit DAC sounds. This article includes several sound samples for the various DAC options and demonstrates some software abstraction that allows for multiple DAC options.
