What's wrong with the ISO 19011 definitions?
3.1
audit
NOTE Internal audits, sometimes called first party audits, are conducted by, or on hehalf of, the organization itself for management review and other internal purposes and can form the basis for an organization's self-declaration of conformity. In many cases, particularly in smaller organizations, independence can be demonstrated by the freedom from responsibility for the activity being audited.
NOTE 2 External audits include those generally termed second and third party audits. Second party audits are conducted by parties having an interest in the organization, such as customers, or by other persons on their behalf. Third party audits are conducted by external, independent auditing organizations, such as those providing registration or certification of conformity to requirements of ISO 9001 and ISO 14001.
(emphasis added)
Absolutely nothing except for the fact that they are so simple to understand they can't be true, so it's easier to make up your own and continue getting lost going from the bedroom to the kitchen and totake other with you on the whirlwind tour.
