- 3. Introduction Hello and welcome to lesson 3 of Introduction to Music Production. I’m Saijal from South Africa and today I’ll be presenting the different categories of audio effects used in music and what properties of sound they affect. 3 Introduction to Music Production Lesson 3 – Categories of Effects
- 4. Audio Effects and Types Audio effects are devices (in physical or digital form) which are used to alter how a piece of audio sounds. In the DAW we could refer the audio effects as Digital Signal Processing or DSP. We have 3 categories of effects. Below is a list of these effects as well as which property of sound they relate to. Dynamic Effects Applies to amplitude Delay Effects Applies to Propagation Filter Effects Applies to Timbre Lets have look at the above in a little more detail in the slides that follow. 4 Introduction to Music Production Lesson 3 – Categories of Effects
- 5. Dynamic Effects Dynamic effects processors/plugins act on the dynamic range of your music – IE the range between the loudest and softest sounds. By adding a dynamic effect you can essentially increase or decrease this range. When an incoming audio signal crosses a set threshold level, the processor adjusts the volume according to parameters set by you. Examples of dynamic effects plugins are Compressors, Limiters, Gates and Expanders. Each of the above works differently. Limiters for example limit the volume of the incoming sound to the threshold level. Sound higher then the threshold will remain at that threshold. Compressors on the other hand scale the volume down when the threshold is reached. Some important controllers that you will find on your dynamic effects plugin are threshold, attack, release, ratio and gain. 5 Introduction to Music Production Lesson 3 – Categories of Effects
- 6. Delays Effects 6 Introduction to Music Production Lesson 3 – Categories of Effects As the name implies, delay effects basically delay the incoming audio signal and outputs it after a specified time. Sound coming into the effect is split into a wet (or delayed) signal and a dry (or unaffected) signal. The wet signal goes into a buffer from where it emerges after a predefined time (delay time – usually in milliseconds). The output from this buffer is then splits into 2 paths. One path feeds back into the buffer while the other gets mixed with the dry signal using the wet/dry control. Examples of delay effects include delay, reverb, phasers and flangers. Some common controls found on delay effects plugins include delay, feedback & wet/dry mix. Wet/dry may be in the form of one controller or a separate controller for each.
- 7. Filter Effects Filters allow you to amplify or attenuate certain frequencies of a sound. A low-pass filter will allow low frequencies to pass through and block the high frequencies. A high- pass filter will do the exact opposite. Band-pass filters lie between low-pass and high-pass. These allow for the a narrow range of frequencies to go through while filtering out frequencies above and below the range in question. 7 Introduction to Music Production Lesson 3 – Categories of Effects
- 8. Conclusion This presentation only scratches the surface of audio effects. There is a lot that can be said about each of the plugins in each category as I discovered when researching the topic for this presentation. Below are some of the links that I used which you might find useful as well. Some of them go into some detail about the common controllers (wet/dry, attack, release etc) and what they mean or do so I strongly suggest reading them if you are new the audio effects. Thanks for the making time to read and evalute.
