39. An apparatus comprising at least one processor and at least one memory storing computer program code, wherein the at least one memory and stored computer program code are configured to, with the at least one processor, cause the apparatus to at least: obtain user provided information and context information associated with said user provided information, in consequence to any user operation against said apparatus, wherein said context information is related to at least one current condition of the apparatus at the time of said any user operation, wherein said user provided information includes user provided audio information; access a code basis representing a plurality of coding symbols, said code basis comprising a pre-defined number of pre-defined frequencies, wherein said plurality of coding symbols represents a character and a symbol code table employable for coding said meta-information wherein said code basis is defined within a first frequency range, wherein said first frequency range is one frequency range of a plurality of frequency ranges forming a total frequency range within the frequency range of said user provided audio information, wherein said code basis is repeated within at least one further frequency range out of said plurality of frequency ranges; code said meta-information in accordance with said code basis defined within said first frequency range and repeated within said at least one further frequency range to obtain redundancy; combine user provided audio information and said coded meta-information by embedding said coded meta-information into said user provided audio information; and direct storage of said user provided information having embedded said embedded meta-information in a history storage in order to establish an information history functionality; wherein said meta-information is employable for retrieval of said user provided information by matching request information of a retrieval request with said meta-information for selecting a user provided information being assigned to said meta-information matched to said request information.
39. An apparatus comprising at least one processor and at least one memory storing computer program code, wherein the at least one memory and stored computer program code are configured to, with the at least one processor, cause the apparatus to at least: obtain user provided information and context information associated with said user provided information, in consequence to any user operation against said apparatus, wherein said context information is related to at least one current condition of the apparatus at the time of said any user operation, wherein said user provided information includes user provided audio information; access a code basis representing a plurality of coding symbols, said code basis comprising a pre-defined number of pre-defined frequencies, wherein said plurality of coding symbols represents a character and a symbol code table employable for coding said meta-information wherein said code basis is defined within a first frequency range, wherein said first frequency range is one frequency range of a plurality of frequency ranges forming a total frequency range within the frequency range of said user provided audio information, wherein said code basis is repeated within at least one further frequency range out of said plurality of frequency ranges; code said meta-information in accordance with said code basis defined within said first frequency range and repeated within said at least one further frequency range to obtain redundancy; combine user provided audio information and said coded meta-information by embedding said coded meta-information into said user provided audio information; and direct storage of said user provided information having embedded said embedded meta-information in a history storage in order to establish an information history functionality; wherein said meta-information is employable for retrieval of said user provided information by matching request information of a retrieval request with said meta-information for selecting a user provided information being assigned to said meta-information matched to said request information. 43. The apparatus according to claim 39 , wherein the at least one memory and stored computer program code are configured to, with the at least one processor, further cause the apparatus to: provide a correlation basis comprising each frequency being included in a set of code bases representing a plurality of coding symbols, said coding symbols being employed for coding said meta-information; and apply said correlation basis onto said user provided audio information having embedded said meta-information to extract said meta-information; wherein said extracted meta-information being available for retrieval.
