Hi All: Some information that may be of use, concerning to the WPI rules for royalties et al in <audio> files. What we know as rights. Uh, Meta elements required * Title : 100% * Artist ( Interpreter): 12% * Time: lenght of the <audio> piece. Royalties are assigned by time sequences. * Year: (_Objective Reason: It use to happen that some__ <audio> files have the same name, thus causing a mistake in the attribution to the artist as it happen in the past_) * Composer: 20% * Arrangements: 20% * Producer: 40% * Label: It depends on the contract, but as an agent collects all the rights * Software: Last but not least, some software use in the production of audio has its own rights. Uh. Hope this information it helps for the meta-tag issues _BTW . There is a new start-up company named orfium.com, which CEOs now all this issues, there is the cahnce ask them for more info._ Cheers --- Delfi Ramirez -- At Work My digital signature [1] 0034 633 589231 delfin@segonquart.net [2] twitter: @delfinramirez [3] IRC: segonquart Skype: segonquart [4] http://segonquart.net http://delfiramirez.info [5] On 2017-04-15 13:46, Roger Hågensen wrote: > On 2017-04-14 22:23, Andy Valencia wrote: > >> Ok.
