The admissibility of summaries is a matter within the discretion of the court. The Texas Supreme Court has held that some of the elements may be inferred and need not be shown in detail. The court also held that specific objections are required to preserve error in improperly admitting recordings. The rule of optional completeness applies to tape recordings introduced during trial. This rule provides that the adverse party may at any time introduce any other part or any other recorded statement which ought in fairness to be considered contemporaneously with it.
