Bitrate simply refers to how much data is expressed per second. These problems are jitter, high frequency mirroring, narrow dynamic range, and limited bitrate.īefore launching into the nuts and bolts of how everything works, you need to know three terms: bitrate, bit depth, and sample rate. Now, because DACs aren’t perfect, sometimes this leads to problems. The unit then outputs a wave that intersects all those points. To do that, it needs to translate the bits of data from digital files into an analog electrical signal at thousands of set times per second, otherwise known as samples. The job of the DAC is to take a digital samples that make up a stored recording and turn it back into a nice continuous analog signal. The higher the frequency, the higher the note. If you’ve heard that word before, you know that what frequency a sound is also corresponds to what note it is. Each wave will have a crest and valley-called a cycle-and how many cycles there are in a second is called frequency(displayed as Hz). When computers record an analog signal, typically it will be displayed in what’s called a waveform, or a representation of the wave where the Y axis is amplitude (how powerful the wave is), and the X axis is time. Low bitrates (a) can mangle the waveform a bit, but higher bitrates (b) can sound better in certain circumstances.Īll audio, whether it’s stored on vinyl or in an MP3 forms a compression wave when it’s played back. But seriously, don’t sink too much money into this. You could also decide to throw money at the problem by picking up an ODAC or O2 amp + ODAC combo, but that may be overkill.
FiiO makes plenty good products for cheap, and if you want an amplifier to go along with the DAC so you never have to worry about that either, their E10K is a solid pick for under $100.

This would also fall under the category of “looking for something to spend money on,” which isn’t the best use of your funds in terms of upgrade opportunities.īecause DACs are a largely spec-driven item, you can almost always pick out the one you need simply by looking at the packaging. Otherwise, if you’ve convinced yourself that your existing DAC is the limiting factor in your playback system and that upgrading it will yield a worthwhile improvement, then that too might be considered a reason to splurge. If you already have an external DAC and are running into any of those issues, you should check out this article. The main (real) reason you’d get a new DAC today is that your current system-be it your computer, smartphone, or home system-has noticeable noise, objectionable distortion or artifacts, or is incapable of operating at the bitrate of your audio files.

Where it used to be true that your digital Walkman or laptop’s internal DAC chip wouldn’t be suitable for high-bitrate listening, there are plenty of portable devices nowadays that can keep up just fine.īuying an external DAC means the noisy environment in your computer won’t mess with your music, though improvements will be minor.
Better tech has made shortcomings of even the cheapest chips practically inaudible, while digital music has exploded in quality past the point of diminishing returns. Who wants to listen to low-quality tunes?īut digital music has come a long way since then.
Lower sample rates, badly encoded MP3s… there were tons of things that children of the 90s had to deal with when it came to audio. Sometimes the DAC would have poor filtering, would be improperly shielded-introducing noise-or the power supply might be poorly regulated, impacting the quality of the rendered output.
This became particularly apparent when consumers started using their PCs as an audio source. High-end headphones and speakers could reveal source components, their DACs and output stages as the weakest links in the audio chain. Much like headphone amplifiers, standalone DACs came about as a response to poor audio quality at the consumer level.
