SLS is a new technology for scalable audio coding. Primephonic offers this format up to 24-bit with a maximum sampling frequency (sample rate) of 192 kHz.
With cloud-based music streaming services, bandwidth can vary drastically depending on whether you use a WiFi network or mobile network. As a result, streaming services store the same audio content multiple times on their server, each with a different file type and bit rate.
To prevent this, SLS offers a solution so that only a single file is necessary. This file dynamically adjusts to the available bandwidth, using scalable audio frames. In this way, a listener does not have to choose between high or low audio quality, because the adaptive way of streaming makes it possible to always have the best possible experience based on the available bandwidth.
