A computer is not a recording device in the same way that a microphone, camera, or tape recorder is. A computer can be used to store and process recordings, but it cannot create them on its own.

In the United States, only one party to a conversation needs to consent to the recording. This means that you can record a conversation without the other person's knowledge or consent, as long as you are a party to the conversation.

Recordings are not always admissible in court. In order to be admissible, they must be relevant to the case and they must be authentic. This means that they must be shown to be accurate and reliable.

Courts consider all of the above factors when determining the admissibility of a recording. They want to make sure that the recording is relevant to the case, that it is authentic, and that it was made in a way that is fair and impartial.

When recording a conversation for legal or forensic purposes, it is important to use a high-quality recording device, to make sure that the recording is clear and audible, and to identify all of the parties to the conversation. This will help to ensure that the recording is admissible in court.
