1. A method for processing an audio signal, the method comprising:conducting, using a first instance of an audio personalization application running on a first audio output device, a user hearing test;
outputting, to a server, user hearing data from the user hearing test;
storing the user hearing data on a database associated with the server, wherein the user hearing data is stored using a unique identifier of the user as reference;
determining, based on the user hearing data, a set of calculated digital signal processing (DSP) parameters for a given sound personalization algorithm;
receiving, at the server, a request for personalized auto playback at a second audio output device, the request generated in response to a second instance of the audio personalization application running on the second audio output device receiving a user input comprising the user's unique identifier, wherein the second audio output device is different from the first audio output device;
outputting the calculated DSP parameters to the second instance of the audio personalization application running on the second audio output device, wherein the calculated DSP parameters are outputted by the server in response to receiving the request and the user's unique identifier from the second audio output device; and
processing, on the second audio output device, an audio signal by using the given sound personalization algorithm parameterized by the calculated DSP parameters.
