DACs and ADCs
When many listeners think of listening to music in Direct Stream Digital (DSD), the first question that comes to mind is what audio gear and software will be needed. The answer to that question will be an audio component (digital player, portable or converter) that includes a Digital to Analog Converter (DAC) that converts DSD music to analog for your musical enjoyment. But then, there is this other great thing, recording!
Recording to DSD
There is another piece of the puzzle that is drawing more and more attention these days. This is the audio gear that enables recording professionals and listeners to record music and even your collection of Analog Tapes and Vinyl LPs to DSD. To transfer live music and other music sources to DSD requires the use of another type of converter – an Analog to Digital Converter or ADC.
ADCs for Recording Studios & Pro Use
The initial Analog to Digital Converters (ADC) for recording studio and professional use appeared in the early days of DSD and the Super Audio CD (SACD) disc from companies like dCS, EMM Labs, Mytek, Merging Technologies, Prism, Ayre Acoustics and Digital Audio Denmark. They offered Stereo and Multichannel (up to 8 channels per converter) analog to DSD conversion at the standard DSD 64fs (64 times the CD bit rate).
As interest grew in higher bit rate DSD recording, the recording industry saw the development of ADCs that provided a choice of standard DSD 64fs bit rate recording as well as double DSD (DSD 128fs) and quad rate DSD (DSD 256fs) recording from the pro equipment makers.
Today these higher DSD bit rate ADCs have proven quite popular. For example, Merging Technologies recently reported sales of over 1,000 of their Horus and Hapi model ADCs with 8 channels of up to DSD 256fs recording capability.
Recording Small Bands & Music Venues
The next phase of ADC development responded to the need to provide high quality yet affordable DSD recording capability for recording small bands, music venues and even speeches and lectures. Products from companies including Korg, Sony and Tascam brought ADCs and portable DSD recorders that sell for as little as $999 and yet offer true DSD stereo recording to the market.
Converting Your Analog Tapes & LPs to DSD
In the last year, this technology has started to reach the home audio market. Several products have been introduced that provide easy to use recording software and ADCs to transfer your Analog Tapes and LPs to DSD. This provides a new way to enjoy your music and expand your music library.
Products in the home audio ADC category include:
- Astell & Kern’s new AK Recorder ($899) which records music played on one of the company’s 300 series portable players to DSD
