Audacity generally records all sounds (depending on your settings). You can set it so that it records from your mic, or you can set it so that you can record from your speaker output, thereby recording any sort of conversation taking place in a program such as TeamSpeak. I suggest you record all voices, including yours; this way the context of the conversation is easier identified without assuming there was no instigation on your part.
Now, while I agree with everything Chrono said in that it isn't the responsibility of higher-ups to hold your hand to report baddies, keep in mind not to do what others have done in the past; ideally recording each and every event of someone you dislike as "evidence" against their behaviour. What I mean is simply this:
Is what you're recording relevant to your claim?
Are you just doing it to get rid of someone you dislike (is this only beneficial to you, not everyone)?
Does your evidence provide both sides of the story, not just yours?
In other words, if you have a personal vendetta against someone who seems to only have a problem with you, then alert a higher-up and see if you can arrange a talk with your "enemy" while a higher-up is present to see if some sort of compromise can be made.
Member Protests and the like are typically reserved for those you think are representing the clan negatively, or if that person is an ongoing problem within a group of people; however, I'm not saying this doesn't mean you can't report someone who is harassing you maliciously, feel free to do so if you believe they are genuinely being hostile.
