Once you have an Audigo mic, you can manage your account by visiting https://account.audigolabs.com and logging in with your email and password. You can then add a Studio or Pro plan.
First time subscribers will automatically receive their first month free when they add a plan.
For Canadian customers, if you do not already have an active billing account setup (i.e. you received Audigo as a gift or are using a different email address than the one used on the original order) please contact support@audigolabs.com for help with managing your account details.
