Information is great, and so is doing something right the first time (a stitch in time…). But be careful that you’re not so caught up in reading and learning that you never actually do anything. Your first recording may not be spectacular. It may even be spectacularly terrible. But who cares? Get out whatever recording equipment you have (I’ll bet your phone can record audio/video) and get started. You may find your no-budget recordings are enough motivation to make some small investments in recording gear.
