[1] Plaintiffs assign error to admission in evidence over their objections of testimony of defendant’s witnesses Case and Smith, and the admission in evidence of the tape recording, all of which concerned statements made by plaintiff Annette Searcy (now Levi), mother of the child whose paternity is here at issue, in January 1964 in which she admitted having had sexual intercourse with other men. There was no error in admitting evidence concerning these statements. Contrary to plaintiffs’ contention, the statements attributed to Annette Searcy concerned acts of intercourse which the jury could legitimately find from the evidence occurred during a period when the child could have been conceived. Plaintiffs’ contention that the central inquiry here is not what Annette Searcy said but she actually did is, of course, correct. However, in this instance evidence of what she said she had done was clearly admissible to prove what she had actually done. She is a party' to this action, and the statements attributed to her were admissible as admissions. 2 Stansbury’s N. C. Evidence (Brandis Revision), § 167. Moreover, that on cross-examination she denied having made the statements did not preclude defendant from offering evidence that she did make them. Defendant’s evidence was not offered or admissible merely for the purpose of contradicting plaintiff Annette Searcy Levi’s testimony but as substantive evidence relevant to the central issue in this case. The trial judge’s instruction to the jury that they could consider the challenged evidence only for the purpose of determining the credibility of Annette Searcy Levi as a witness was an error against defendant and favorable to plaintiffs for which they cannot complain.
[2, 3] The tape recording as such was also properly admitted in evidence. Sound recordings, if relating to otherwise competent evidence, are admissible providing a proper foundation is laid for their admission. State v. Lynch, 279 N.C. 1, 181 S.E. 2d 561 (1971) ; Searcy v. Justice and Levi v. Justice, supra; see Annot., 58 A.L.R. 2d 1024. Before the tape recording was ad*514mitted into evidence in the present case, defendant' presented the testimony of his witness, Clifford Case, who made the recording, concerning the manner in which it was made. Case testified that at defendant’s request in January 1964 he hid in the trunk of defendant’s car where he operated a tape records ing machine on which he recorded a conversation between defendant and Annette Searcy, who were seated in the front seat of the car. Case identified the reel and the tape presented at the trial as the reel and tape which he used to record the conversation. He also testified that he knew the voices of defendant and Annette Searcy, that he heard all of the conversation between them, that the conversation was reproduced on the tape, and that nothing was left out. Evidence was also presented to show that after the recording was made in 1964, the tape remained in defendant’s possession until he was first charged in this case in 1971, when he delivered it to the attorney who then represented him in Hendersonville, N. C. The record on appeal contains the stipulation signed by counsel for plaintiffs and defendant that the tape recording offered in evidence by defendant at the trial is the same tape recording delivered to defendant’s present counsel by his former attorney, that the tape recording was continually in the custody of the present counsel from the time of its delivery to him until the trial, that no alterations or additions were made to the tape subsequent to its delivery to defendant’s present counsel, and that these matters were stipulated by plaintiffs’ counsel upon voir dire prior to the time the tape was offered into evidence. We .hold that a proper foundation was laid for admission of the tape recording in evidence and that it was properly admitted Jn evidence.
[4] While testifying as to the arrangements he had made in January 1964 to get a tape recorder and have the conversation recorded, defendant was asked by his counsel if he got “some expert help on it,” to which he replied, “Yes, sir, from this sound technician.” Plaintiffs’ counsel moved to strike, and the court ruled, “As to expert, strike that.” Defendant was then asked by his counsel if he had consulted “someone in the electronics field about it,” to which he replied that he “got a' man that runs a sound and record shop in Hendersonville to instruct us on how to install it after we got the power converter.’’ Plaintiffs’ counsel moved to strike, “particularly as to the instruction which is hearsay.” The rulings of the court relative to' this testimony form the basis of plaintiffs’ third’ assignment of *515error. In these rulings we find no error. The court allowed plaintiffs’ motion to strike the reference to the sound technician “as an expert,” and it was entirely competent for defendant to testify that he “got a man that runs a sound and record shop in Hendersonville” to instruct him how to install the recording machine. The rule excluding hearsay evidence was in no way involved.
[5] Plaintiffs called as a witness the court reporter who served at the first trial for the purpose of presenting her testimony that when the tape was played at a voir dire hearing on the previous trial, it was difficult to hear and she was able to understand “only a word every now and then.” On defendant’s objection the court excluded this testimony, to which ruling the plaintiffs now assign error. In this ruling we find no prejudicial error. The excluded evidence was relevant only on a question as to the authenticity of the tape. Even on that question it had only limited probative value, since whether the tape was more or less audible to a particular witness who heard it under other circumstances when played on different equipment on some prior occasion would not be determinative. Furthermore, the record reveals that plaintiffs here were given ample opportunity prior to trial to investigate fully as to the authenticity of the tápe and as to whether it may have been in any way altered. Prior to the second trial, counsel for the parties met with the judge in chambers for the purpose of listening to the tape so that the court might make a determination as to whether it was of sufficient quality to be heard and understood by thé jury. Following that meeting, plaintiffs moved to require that defendant permit the tape to be examined by an electronics expert of plaintiffs’ choosing. Though no formal order was entered, at the court’s suggestion defense counsel agreed that the tape might be so examined by plaintiffs’ expert, subject to the case being continued if the expert concluded that the tape had been tampered with or was not the same. Plaintiffs’ counsel later stated during the trial that “plaintiffs had decided not to have the tape examined by an electronic expert because the matters had already been the subject of numerous continuances and plaintiffs desired to have the case heard.” Under these circumstances we find no prejudicial error in the court’s ruling excluding the court reporter’s testimony as to what she could hear when the tape was played during the course of the prior trial.
*516We have examined appellants’ remaining assignments of error, and in the trial find
No error.
Chief Judge Brock and Judge Arnold concur.
