In light of newer technologies that have become available, we wanted to clarify section 3.2.3 of our vocals’ EULA. Our company’s position is that we will not prohibit users from using voice changing algorithms on exported audio from our AI vocals.
While it is not required if using the full version of the voice database, we would greatly appreciate if users who utilize exported audio for this purpose would also credit our voice databases for the initial rendition in order to acknowledge our team’s hard work on our vocals.
Lite versions still require credit even when used as the base of a processing workflow in this manner. We also wish to make it clear this applies only to Eclipsed Sounds’ Synthesizer V voice databases. (SOLARIA and ASTERIAN)
While converting exported audio using a voice changer is acceptable under section 3.2.3 of our EULA, it is still absolutely prohibited to develop voice changers, secondary synthesizers, vocal only sample packs, and the like from exported audio using our vocals.
This statement is only for Eclipsed Sounds products.
Other companies have not commented on this, so we must refer to the EULA:
Dreamtonics:
(3) Renditions must not be used as the input to a singing synthesis or speech synthesis model, algorithm, application or any data-driven workflow that generates singing voice or speech.
(3) 合成音声は、歌唱合成または音声合成モデル、アルゴリズム、アプリケーション、または歌声または音声を生成するデータドリブンのワークフローへの入力として使用しないでください。
AHS:
13 When using the product, you must not do any of the following acts, or any act that may lead to such acts

…
(14) 合成音声を、歌声合成や音声合成モデル、アルゴリズム、アプリケーション、または歌声や音声を生成するデータドリブンのワークフローの入力として使用する行為
This means Dreamtonics and AHS voices cannot be used as input to RVC. If you have a product from a different company, check license.txt
in the installation directory.
