Product Design: PD4 - D/A and A/D Design for Today’s High Resolution Audio Formats

With new interest in “ultra” DSD and DXD, A/D and D/A converters, to be fully inclusive, now must support a wide range of PCM formats (1Fs, 2Fs, 4Fs, 8Fs) as well as DSD (64 Fs, 128 Fs, and 256 Fs). Converter design and signal processing influence the performance obtained from these various formats and can also affect how they are perceived. A panel of AD/DA design engineers highly experienced in getting the best out of formats ranging from redbook to high resolution offer their take on these formats and on implementation for optimal quality. Along the way, many of the issues, assertions, less understood areas influencing sonic quality, and perhaps some of the canards that have developed surrounding these formats are discussed.
