According to CNN, ironically, a party-requested recount in Georgia is faster and less involved than the audit that has already taken place:
"Because the margin is still less than 0.5%, the President can request a recount after certification of the results. That recount will be conducted by rescanning all paper ballots," Georgia Secretary of State Brad Raffensperger had said in a statement on Friday after a state audit of the presidential results had been completed.
Georgia already conducted an audit of the presidential ballots, meaning all ballots in the presidential race were counted a second time -- which was a defacto recount. The audit was more rigorous than the recount will be as the audit was a hand recount of every ballot, whereas the new recount will be done by a machine rescan.
The Trump campaign has apparently also requested that ballot signatures be re-verified during this (2nd, nominal) recount, but apparently that signature re-verification is not going to happen:
Under Georgia law, the Trump campaign had two business days from Friday's certification to request the recount, which will be taxpayer-funded.
"Today, the Trump campaign filed a petition for recount in Georgia. We are focused on ensuring that every aspect of Georgia State Law and the U.S. Constitution are followed so that every legal vote is counted. President Trump and his campaign continue to insist on an honest recount in Georgia, which has to include signature matching and other vital safeguards," the Trump campaign said in a statement.
Signature matching for mail-in ballots is not done in recounts, however, according to campaign law expert Jonathan Diaz, a CNN contributor. Comparing of signatures on envelopes of mail-in ballots to those on file is done earlier in the process. The Trump campaign was upset more ballots were not thrown out because of signature issues.

Trump Requests Georgia Recount, Meaning 5 Million Votes Will Be Tabulated A 3rd Time
While thousands of workers spent most of the last week hand-counting every vote as part of a newly required statewide risk-limiting audit, this recount will be different.
The law calls for a recount to be conducted by retabulating every ballot through a scanner, the same way they were originally counted in the days following the Nov. 3 election.
In a statement announcing the recount, the Trump campaign demanded that it include signature matching of absentee ballots, despite repeated explanations from Secretary of State Brad Raffensperger's office that fulfilling such a request is illegal and impossible.
Raffensperger said in a op-ed that signatures (too) were already verified twice.
As to the legal distinction between the recount and the audit:
The recount will be done using scanners that read and tabulate the votes. County election workers have already done a complete hand recount of all the votes cast in the presidential race. But that stemmed from a mandatory audit requirement and isn’t considered an official recount under the law.
State law requires that one race be audited by hand to ensure that the machines counted the ballots accurately, and Raffensperger selected the presidential race. Because of the tight margin in that race, a full hand count of ballots was necessary to complete the audit, he said.
Had the (selected) race been not that close,
only a smaller sample of ballots would have had to be hand-counted
in the audit.
