Understanding Music Storage
If you are new to the high fidelity world then you have probably just learned that there is something better out there than the song files we download from Apple iTunes. High-resolution music is a step up from basic mp3 downloads keeping more of the original data that was created when the music was recorded. In other words, you get closer to what was originally heard in the studio or the live venue.
High-resolution audio comes in many formats including PCM, WAV, AIFF, and DSD. These uncompressed files give you a more detailed presentation of your music. You should note that not all high resolution players such as Astell & Kern, Onkyo, and Aurender play the same file types so you need to make sure you download files your devices will be able to read.
The Aurender X100L Digital Music Player and N100H Music Processors with hard drive storage support DSD (DSF, DFF), WAV, FLAC, ALAC, APE, AIFF, M4A and other major formats at native bit and sampling rates. You can download these types of files from websites like HDtracks.
These uncompressed files generally require approximately 50% more storage than the audio files you would download from iTunes. This is why high-resolution players provide more storage options, often giving you external storage choices as well.
CDs, while still a higher resolution choice than mp3 formats, are not considered high-resolution files. High-res audio typically starts at 24-bit, with a sampling frequency of 88.2kHz or higher. CDs are only 16-bit with a sampling rate of 44.1kHZ. The typical high res files of 24bit/96kHz will take up three times more storage than a CD. Once you get up to DSD formats your storage space significantly decreases.
That being said, the Aurender products provide more than enough storage options for you to continue your love of music and vast music collection.
