Hi-Res Audio Explained


What means hi-res audio?

High-resolution audio (hi-res audio, HRA, high definition, HD) is designed as the next step after CD digital quality (44.1 kHz / 16 bit). HRA appears to improve sounding of compact disk.

In simple words, HRA has higher resolution than traditional audio compact disc. From technical point of view, hi-res audio has higher bit depth and sampling rate, than 16-bit and 44100 Hz of CD.

On the consumer market, hi-res audio began to spread in end of 1990's. And now we have a wide range of HD music formats in online stores and audiophile streaming services.

WAV, FLAC, AIFF are most popular audio formats with high sampling rates and bit depths.

DSD (Direct Stream Digital) occupies a special place in family of high-definition recordings. It's 1-bit format with very high sampling rate.

Also, modern lossy data-compressied formats MQA and AAC support hi-res recordings.

But in fact, HRA allows solving some issues of low sampling frequencies.

Do you get benefits? There is no answer the question. It is personal choice. Should you try high resolution? Definitely.

There is nothing terrible. Many modern devices already supports wide range of sampling rates and bit depths. And, you get for free hi-fi music downloads for testing of your setup's abilities. Read about all about it below.


How can I listen to HD music?

To lictening HD music, you need capable device that is considered below. Also, you can download hi-res audio files in the Internet.

Could you improve sound via upsampling?

Just changing of sampling rate improves nothing. It is an abstract thing in a vacuum.

But, if you consider a higher sampling rate and bit depth with your musical device, it may give advantages.


Where to download hi-res audio?
