# Sound Design Basics Guide Utilizing pre-recorded material like Apple Loops and Ableton Live clips are a great way to create music for any project. However, if you find yourself wanting to design your own sounds from scratch, it is worth first understanding a few fundamentals. We will use a software wavetable synthesizer called [Vital](https://vital.audio/) for our short sound design exploration (but any software synth will do). What's cool about it is that: 1. ***It is free*** 2. You can use it as stand-alone software or inside any DAW on macOS or Windows (GarageBand, Logic Pro, Ableton Live etc.) - So, any cool sound you make can be used anywhere! Download Vital for free [here](https://vital.audio/). ![Final Sound](https://files.slack.com/files-pri/T0HTW3H0V-F02UA2S1R38/screen_shot_2022-01-18_at_10.13.03_am.png?pub_secret=cf0895e71c) The sound we will be making is this warm, pulsating drone pad: <iframe style="border: 0; width: 100%; height: 52px;" src="https://bandcamp.com/EmbeddedPlayer/album=3081038187/size=small/bgcol=333333/linkcol=ffffff/artwork=none/transparent=true/" seamless><a href="https://danielbermudes.bandcamp.com/album/sounddesignbasics">SoundDesignBasics by Daniel Bermudes</a></iframe> ...this can be great for scoring podcasts too :) Feel free to copy the settings in the images too! ## OSCILLATOR We begin our exploration inside the Oscillator section. Here, we have *waveforms* that provide us all sorts of different sonic possibilities. There are countless wave shapes to choose from, but there are (4) fundamental ones: <iframe style="border: 0; width: 100%; height: 42px;" src="https://bandcamp.com/EmbeddedPlayer/album=3303256570/size=small/bgcol=333333/linkcol=ffffff/artwork=none/track=4204695691/transparent=true/" seamless><a href="https://danielbermudes.bandcamp.com/album/waveform-examples">Waveform Examples by Daniel Bermudes</a></iframe> <iframe style="border: 0; width: 100%; height: 42px;" src="https://bandcamp.com/EmbeddedPlayer/album=3303256570/size=small/bgcol=333333/linkcol=ffffff/artwork=none/track=2406044579/transparent=true/" seamless><a href="https://danielbermudes.bandcamp.com/album/waveform-examples">Waveform Examples by Daniel Bermudes</a></iframe> <iframe style="border: 0; width: 100%; height: 42px;" src="https://bandcamp.com/EmbeddedPlayer/album=3303256570/size=small/bgcol=333333/linkcol=ffffff/artwork=none/track=489423611/transparent=true/" seamless><a href="https://danielbermudes.bandcamp.com/album/waveform-examples">Waveform Examples by Daniel Bermudes</a></iframe> <iframe style="border: 0; width: 100%; height: 42px;" src="https://bandcamp.com/EmbeddedPlayer/album=3303256570/size=small/bgcol=333333/linkcol=ffffff/artwork=none/track=1880707037/transparent=true/" seamless><a href="https://danielbermudes.bandcamp.com/album/waveform-examples">Waveform Examples by Daniel Bermudes</a></iframe> Since we have (3) available oscillators, we can have up to three waveforms playing at the same time! But, for our example we will just use Oscillator 1 to play a sawtooth wave. ![Oscillator Section](https://files.slack.com/files-pri/T0HTW3H0V-F02U2M7F2T1/screen_shot_2022-01-18_at_10.53.37_am.png?pub_secret=deb9341a83) - To find it, click the wavetable selector (default is 'Init') and select the 'Basic Shapes' category. - Use the vertical white slider to scroll through the various waveforms until you find the sawtooth shape (pictured above) - IMPORTANT: under [Unison](https://soundbridge.io/make-bigger-synths-using-unison/), increase the Voice count from '1v' to '7v', and decrease the Detune amount to a value around '6%' (this will make our synth sound "larger than life") To play these sounds, use the keyboard at the bottom of Vital or your computer. This what we have so far: <iframe style="border: 0; width: 100%; height: 42px;" src="https://bandcamp.com/EmbeddedPlayer/album=3081038187/size=small/bgcol=333333/linkcol=ffffff/artwork=none/track=3801139475/transparent=true/" seamless><a href="https://danielbermudes.bandcamp.com/album/sounddesignbasics">SoundDesignBasics by Daniel Bermudes</a></iframe> ## FILTER Filters allow for shaping the tone of a sound. There are (2) basic ones to know: - Low Pass: Cuts away high frequency content, allowing lower frequencies to *pass* through - High Pass: Cuts away low frequency content, allowing higher frequencies to *pass* through In our example we will use a lowpass ladder filter, a recreation of the classic Moog Ladder Filter developed by [Bob Moog](https://moogfoundation.org/about/humble-visionary/) in the 1960s. ![Filter Section](https://files.slack.com/files-pri/T0HTW3H0V-F02UVCFT68H/screen_shot_2022-01-18_at_10.09.12_am.png?pub_secret=f801324886) - Turn on the filter (orange button on top-left corner) - Select the 'Ladder' filter with a slope of '24db' in the drop-down menu. - Increase the **Drive** parameter for a more saturated sound. - To open or close the filter (like in our example), move the horizontal white slider. The vertical white slider shown is the [Resonance](https://electronicmusic.fandom.com/wiki/Resonance#:~:text=In%20the%20types%20of%20filter,resonance%20setting%2C%20self%2Doscillate.) parameter. Adjusting this can create those sci-fi, alien tones (especially when opening/closing the filter). I left a very tiny amount for higher frequency detail. Now we have this: <iframe style="border: 0; width: 100%; height: 42px;" src="https://bandcamp.com/EmbeddedPlayer/album=3081038187/size=small/bgcol=333333/linkcol=ffffff/artwork=none/track=2536669177/transparent=true/" seamless><a href="https://danielbermudes.bandcamp.com/album/sounddesignbasics">SoundDesignBasics by Daniel Bermudes</a></iframe> ## ENVELOPE In short, an envelope describes how a sound morphs over time. The most basic one to look at is the [ADSR](https://www.masterclass.com/articles/adsr-envelope-explained#what-is-an-adsr-envelope) envelope: - Attack - Decay - Sustain - Release Every sound you hear goes through these (4) distinct stages. An envelope will allow us to modulate a parameter in Vital on a note-by-note basis (every new note will trigger the envelope again). ![Envelope Section](https://files.slack.com/files-pri/T0HTW3H0V-F02UGPXNR0B/screen_shot_2022-01-18_at_10.13.25_am.png?pub_secret=49dd31a5c0) Inside **ENV 1**, specifically experiment with the 'Attack' and 'Release' knobs. Hear how the sound slowly fades in and out when you increase these two parameters. *NOTE: **ENV 1** is specifically assigned to control the <u>amplitude</u> of the sound. **ENV 2 & 3** are left available for modulating other parameters in the synth.* Check it out: <iframe style="border: 0; width: 100%; height: 42px;" src="https://bandcamp.com/EmbeddedPlayer/album=3081038187/size=small/bgcol=333333/linkcol=ffffff/artwork=none/track=1043160850/transparent=true/" seamless><a href="https://danielbermudes.bandcamp.com/album/sounddesignbasics">SoundDesignBasics by Daniel Bermudes</a></iframe> The details are in the beginning and end of the example. Listen carefilly how the sound comes in and goes out. Subtle, but effective. ## LFO Similarly to an envelope, an LFO (Low Frequency Oscillator) allows us to modulate a parameter *continuosly* unlike an envelope that is triggered. ![LFO Section](https://files.slack.com/files-pri/T0HTW3H0V-F02UA35FSFQ/screen_shot_2022-01-18_at_10.10.10_am.png?pub_secret=004dc26a17) For our sound: - Select 'Saw Down' in the drop-down menu - Drag up in the Frequency box to change the *rate* of this pulsing effect. - In the Mode box, select 'Sync' - IMPORTANT: Hover over **LFO 1** until you see this icon: ![Icon in LFO box](https://files.slack.com/files-pri/T0HTW3H0V-F02UFFC4MA9/screen_shot_2022-01-18_at_2.22.51_pm.png?pub_secret=b99960aac2) - Click, drag, and drop it over to the Filter section. - This assignment will now allow **LFO 1** to modulate the filter, giving us that pulsating effect! - You can change how much the LFO is modulating the filter by increasing/decreasing the orange circle (change it to taste) Now hear it: <iframe style="border: 0; width: 100%; height: 42px;" src="https://bandcamp.com/EmbeddedPlayer/album=3081038187/size=small/bgcol=333333/linkcol=ffffff/artwork=none/track=3411974193/transparent=true/" seamless><a href="https://danielbermudes.bandcamp.com/album/sounddesignbasics">SoundDesignBasics by Daniel Bermudes</a></iframe> **Pro Tip:** Often times, a complex sound is the result of just one LFO or Envelope modulating various parameters on a synth. Experiment with connecting LFOs and Envelopes to different areas in Vital; you'll begin to develop cool things quickly. ## EFFECTS - [Chorus](https://www.izotope.com/en/learn/understanding-chorus-flangers-and-phasers-in-audio-production.html#chorus) - [Compressor](https://www.izotope.com/en/learn/multiband-compression-basics-izotope-mastering-tips.html) - [Delay](https://www.teachmeaudio.com/mixing/equipment/effects/delay) - [Reverb](https://www.izotope.com/en/learn/reflecting-on-reverb-what-it-is-and-how-to-use-it.html) In short, effects allow us to add even more character to a sound. Vital has a wide range of effects that add depth, space, thickness etc. in our sound design. Try them all in the Effects Tab! The effects used in this example are these: ![Effects Window](https://files.slack.com/files-pri/T0HTW3H0V-F02U24JPYKH/screen_shot_2022-01-18_at_10.05.20_am.png?pub_secret=c6b907c070) The result now sounds pretty similar to what we had in the beginning: <iframe style="border: 0; width: 100%; height: 42px;" src="https://bandcamp.com/EmbeddedPlayer/album=3081038187/size=small/bgcol=333333/linkcol=ffffff/artwork=none/track=2991392659/transparent=true/" seamless><a href="https://danielbermudes.bandcamp.com/album/sounddesignbasics">SoundDesignBasics by Daniel Bermudes</a></iframe> --- While designing something from scratch is obviously fun, do check out the available presets in the main drop down menu; they're super rad and valuable for learning!
