This is the fourth in a series of posts documenting the development of Play With Your Music, a music production MOOC jointly presented by P2PU, NYU and MIT. See also the first, second and third posts.
After PWYM participants have tried mixing using just levels and panning, the next step is to include audio effects for additional audio manipulation. As a painless introduction, you can load any track from SoundCloud into our own miniature web-based effects unit, #PWYM Live Effects. Then it’s time to open up some dry stems in Soundation. In addition to mixing and panning, you can now do some creative application of Soundation’s effects. These include:
Both low-pass and high-pass filters are available, which block high and low frequencies, respectively. Why would you want to do such a thing? There are practical and expressive reasons. The practical one is to keep sounds from fighting each other in the mix. So, for example, my electric guitar has a very bass-heavy sound. If there’s a bassist on the track along with me, together we’re going to sound like mud. By applying a high-pass filter to my guitar, I can stay out of the bassist’s way and still get across most of the information in my sound. Similarly, I’d want to low-pass the bass for the same reason.
