Some packages are aimed at musicians, others at single voices, or a small number of speakers. That said, it’s possible to spend hundreds of dollars on audio editing software, but there are free alternatives too - it’s a market that supports a variety of entry points, and it’s important to choose the right one for you so you don’t end up paying over the odds, but equally don’t end up saddled with software that doesn’t support the features you need.
A laptop, a quiet place, a decent mic and some of the best audio editing software will produce a result that, while not perfect, will get the job done at a fraction of the cost and still deliver extremely high quality audio. You no longer need a full recording studio with padded walls and expensive mics to create good-quality audio.
