Using Apple's Compressor to Convert Audio

If you've bought Apple's Logic Studio including Logic Pro 8, then you've also got the Compressor application sitting in your Applications folder.

The application isn't for audio dynamic compression, it's for converting file formats, specifically encoding video files from one format to another. It can also convert files from one audio format to another.

Why bother?

What's the audio equivalent of RAW image processing?

Radial Engineering Re-Amping Kit

I like it when something just works, but I always feel a bit ambivalent when I can't really notice it working.

The Kit

In this case, I've just been using the Radial Engineering Reamping Kitreamping-kit-slice-370.jpg. It consists of two main components (the J48 active phantom DI and the X-Amp amp driver) plus a power supply for the X-amp and a plastic box to hold it all in.

Using Compressors to increase attack - Musical Creativity 45

Compressors are regularly used to tame errant dynamics or to increase the perceived volume of a track. As well as squashing the audio, the compressor can be used to bring out some elements more than others.

Use of Tremolo - Musical Creativity 42

I've talked about tremolo as a musical feature before, this time I want to go into more detail.

First things first, let's sort out the guitarists: I don't mean using the tremolo arm/whammy bar or whatever you want to call it ("handle" as my girlfriend called it - and no she won't be picking up my guitars for a while). The whammy bar creates a vibrato feature, not a tremolo. Vibrato alters pitch.

Use random notes - Musical Creativity 38

Create a random part and modify it until it becomes musical. I'll describe a few options for taking a random parts and the processes I use for making them more musical.

1. Creating the randomness

I set Logic on a 4 bar cycle and hit keys at random on my keyboard. I chose a clean electric piano sound since they highlight any dissonance. It's not truly random because it's difficult to unlearn how to play, but after cycling through the 4 bars a few times it did become a mess of notes.

My Home-Grown Mastering Process

Introduction

When I master tracks myself, I do it within Logic Pro. I do not delude myself into thinking that the results of my efforts will be better than that of a professional mastering engineer. My view is that that there are times when mastering tracks yourself is the pragmatic choice. In this article, I provide details of my mastering process. This builds on the article about why process mapping is relevant to music and audio.

Lock the Bass in - Musical Creativity 28

Following on from the article about using gates on drums. I want to describe the main reason I use gates and that's to lock the bass into another pattern such as the kick drum.

It's quite a common use for a gate and when set well, it's subtle and almost unnoticeable, but definitely noticeable when you turn the effect off.
