In electronics, a digital-to-analog converter (DAC or D-to-A) is a device that converts a digital (usually binary) code to an analog signal (current, voltage, or electric charge). An analog-to-digital converter (ADC) performs the reverse operation. Signals are easily stored and transmitted in digital form, but a DAC is needed for the signal to be recognized by human senses or other non-digital systems.

A common use of digital-to-analog converters is generation of audio signals from digital information in music players. Digital video signals are converted to analog in televisions and mobile phones to display colors and shades. Digital-to-analog conversion can degrade a signal, so conversion details are normally chosen so that the errors are negligible.

Due to cost and the need for matched components, DACs are almost exclusively manufactured on integrated circuits (ICs). There are many DAC architectures which have different advantages and disadvantages. The suitability of a particular DAC for an application is determined by a variety of measurements including speed and resolution.



I saw this



And I was wondering are these things useful ? Anyone using similar equipments ?
Nuforce Icon uDAC2 - USB-DAC is quite cheap, 99 euros and has good reviews.

Don't know of that one but yes a DAC can be helpful if you are working professionally.

Pro studios often separate the DAC from the ADC to help reduce induced noise and also dedicate the chip and electronics etc. Specialist dacs tend to come from:

Lavry, Mytek, Forsell and a small number of other high end manufacturers.

Dan Lavry pretty much wrte the AES standards for dac etc. We use a Lavry Black DAC11. I think it costs about £1000 plus taxes. It has properly calibrated and stepped volume, a v. good headphone amp, USB AES/EBU, spdif etc ins and balanced XLR out. Clocking and jitter is possible the best in the business

(We use a Prism for the ADC and analogue hardware loop.)

This is very interesting. The quality of DAC affects directly to the quality of the audio that you record and process so investing on this is investing in quality. As Tony said, this is important if you work professionally with audio. I didn't know that device but it looks good.

In general, the DAC's in Macs have become quite good in the past few years. It's unlikely anything in the $100 range would be an improvement over what you already have.
